    Up until this point, the potential for an AI bust blast radius was limited to corporate investors, but this is going to cause regular retail/401k investors to get exposure, which could have far bigger impacts on a downturn.

    Not to mention the insane wake-up call it is going to be for these AI stocks when 3 months after they launch they have to start making earnings calls and showing their financials. That quarter-by-quarter pressure and scrutiny is no joke, and probably the biggest downside of going public.

    I'm bullish on AI, but kind of bearish on any specific AI company. None of the initial big dotcom companies like AOL or Yahoo survived at the scale they briefly had.

    • panarky 6 hours ago ago

      If we're doing historical comparisons, there was so much hype for AOL and Yahoo that drove valuations far beyond the economics. In time, the hypesters were proved wrong.

      In contrast, there was overwhelming doom and gloom for Google's IPO, in spite of their incredible growth and margin economics. In time, the doomers were proved wrong.

      There's so much doom and gloom about Anthropic that directly contradicts their astounding growth and margins. For a long-term investor, Anthropic is looking a lot more like Google not AOL.

      I can only hope the doomer narrative dominates until I can get a few shares at a reasonable valuation.

      Vibes are almost always wrong. Ignore the vibes and focus on revenue growth rates and inference margins.

      • pseudosavant 5 hours ago ago

        Google is an excellent example of the companies that followed after the initial batch of big dotcom companies. They ate Yahoo's lunch. The dotcom bust was in 2000, and Google went public in 2004.

        I'm betting more on the successors to this initial group of AI companies. The ones that have to build actual profitable businesses.

        • radicalbyte 4 hours ago ago

          Google was easily 10x better than any of their competition. It was effectively alone in the market.

          Most of us were using 56k modems to access the internet back then, Google's search returned results within a couple of seconds. Yahoo, Lycos, Excite, Alta-Vista were still loading. Then the search results themselves were so good you could often just pick the first result. They eventually added a button which just took you directly to the first result. Which I used.

            Curious, why do you say that as if the "I'm Feeling Lucky" button isn't still on the homepage in 2026?

            • bravoetch 3 hours ago ago

              I couldn't even tell you when I used the Google search page. It's been years at least. I wouldn't be surprised if many other people also don't go there to search. I assume most search straight in the url bar.

            > Alta-Vista were still loading

            Your memory is faulty. AltaVista was always super fast--it never had the advertising bloat that the other ones had until the very end.

            The problem AltaVista had was that it didn't scale when the Internet went exponential--so AltaVista would give you good search results until you asked current, topical questions. AltaVista relied on running a single, super-expensive stonking huge Alpha machine while Google ran on lots of commodity servers that spidered constantly.

            • BryantD an hour ago ago

              This is inaccurate. When I was running AV operations around 2000, we were running on a couple dozen huge Alpha machines for the index layer and queries. We had a bunch of smaller machines for Web serving, and a high memory set of Alphas as a caching layer.

              See https://www.usenix.org/legacy/publications/library/proceedin... for the 1997 server count, which was before we got to the three tier architecture.

              We also spidered constantly. A couple of those huge backend Alphas were dedicated to holding the constant spider index. AV had a well earned reputation for quick discovery, although I think Google wound up faster. We suffered a bit from maintaining separate indexes for the main corpus and recent pages, and I imagine Google handled that better.

              But the period of time when our main index went to hell was the period of time when we failed to do a new main index crawl for several months. I won’t get into why that happened politically because my memory isn’t perfect and I don’t want to criticize anyone who won’t see this to stand up for themselves, but it’s absolutely the case that we let the index get stale.

              And I will say that I think the execs were distracted by the idea of challenging Yahoo by buying a shopping site and a local news site of sorts and, unlike the Google of the time, they lacked the wisdom to focus on our primary product.

              And now I fade back into the hedges, until the next time AV comes up… I suspect a high percentage of my HN comments are on this exact topic. It makes me sad.

          When did Google pivot to advertising?

          • parasubvert 3 hours ago ago

            Before the IPO; AdSense came out in 2003. Before that they really make much money.

            Simple text ads to start. It was built on MySQL, Java and C++ and became how they made most of their money.

      • davedx 5 hours ago ago

        "until I can get a few shares at a reasonable valuation"

        I doubt you will. Most likely IPO reference price will be like SpaceX's, 100x ARR or so.

        You're better off buying Google who own a huge chunk of Anthropic at a much saner average.

        • panarky 3 hours ago ago

          If it's 100x ARR then I'll watch from the sidelines.

          But if it's 40x in October, and inference margin is strong, and revenue is still growing 20% per month, then I'm in.

      • ifwinterco 5 hours ago ago

        I don't think it's really doom and gloom, that's mostly on here.

        The normies are all still excited/scared and the valuation based on secondary trading is going up and up.

        Maybe not quite as crazy as the dot com boom but I'd say the current environment for AI and related equities is a lot closer to the mid/late 90s than 2004

        • panarky 5 hours ago ago

          Normies are on fire for SpaceX, where the economics are horrible and the hype is off the charts.

          Normies have never heard of Anthropic, where the economics are incredible and doom vibes are pervasive.

          • boelboel 5 hours ago ago

            I think both have a similar amount of people who know about it. But it might just be my circle which is mostly in finance and some in engineering/medicine. These are also the type of people who actually invest. There's little doom vibes among those who're older if anything they're the one who think we'll get to some agi type situation.

        And ignore debt you can't pay back? Fine during ZIRP era because there was always another $50M around the corner. There is no extra $50B around the corner.

        They've all over-invested in AI, same as the railroads, and it will collapse the same way.

      • ai_fry_ur_brain 4 hours ago ago

        They've changed the rules that will force these companies into every ETF commonly held by people's 401ks. The doomer narrative doesnt matter, they're forcing the common man to be the exit liquidty for the elite before the bubble pops.

        I conjecture that some amount of the "doomer posting" is a consequence of other people realizing what you realized here and attempting to sway public sentiment for personal gain.

        Anthropic is selling a commodity item that was just invented. It’s like investing in someone who is blowing lightbulb glass by hand.

        We’ve already seen a startup make a chip which generates a hundred pages of text in milliseconds. When companies start bringing out hardware like that for cutting edge models, the entire business is dead. AWS will just eat the market.

        Ah yes, time tested and battle hardened inference margins.

      • arw0n 5 hours ago ago

        History does not repeat itself, but it rhymes. Drawing these comparisons to the Dotcom bubble is only of limited utility. I think there's good reason to believe that recursive self-improvement is a bust, and LLM models will become a commodity. The real value lies in multi-modal integration and good harnesses. The current frontier labs are theoretically in a good position to capitalize on this, but it is far from obvious that they will succeed. I think Google and some of the chinese giants are in a far better position to actually go the last mile.

    • munk-a 2 hours ago ago

      It's the indices we need to be concerned about and it's especially the bloated carcass of xAI hanging onto SpaceX.

      SpaceX was a profitable company, it was heavily invested into R&D and had managed to build a tidily profitable connectivity business in Starlink. Now the company is being burdened with all the worthless debt of X and xAI with a likely merger with Tesla following launch just to hand Musk a big check when he hits the valuation targets.

      IPO inclusion on indices should be illegal, the price discovery simply hasn't happened yet and it's a direct grab at the most vulnerable retail investors - the passive index huggers that were told that if they just buy an index it'll never be spectacular and it might dip but it'll steadily go up.

      I would not be surprised if the US Government ends up bailing out retirees over this and cements the country's descent into debt. Pretty much everyone can see it coming, but we have to act as if Elon is valuing his companies in good faith and not just trying to rob a payday.

    • EugeneG 5 hours ago ago

      Reminds me of this... During Apple's 1980 Initial Public Offering (IPO), Massachusetts regulators banned residents from purchasing the stock. The state's securities regulators deemed the offering "too risky" and "over-valued," enforcing a state rule that prohibited IPOs with a price exceeding 25 times earnings.

      • groundzeros2015 5 hours ago ago

        And it was probably prudent to wait. The investors who wanted to take more risk could do that.

        Retroactive reasoning with investments (if I just bought X) is insane.

        • cj 4 hours ago ago

          Indeed.

          They IPO'd in 1980, yet their stock price was below the IPO price for the majority of 1980-1987.

          It also fell to its IPO price for an extended period of time between 1996-1998.

          You hypothetically could have waited 20 years after the IPO before investing without giving up theoretical gains.

            Empires usually go through a long period of decline before they collapse. I'm not sure why you'd think this Empire is immune to collapse or decline.

            You're going to lose everything and your children will have no future. When they're old they'll be speaking from a similar perspective to the people who lived through the decline and fall of the USSR. Keep coping though.

        • EugeneG 4 hours ago ago

          The stock market (and in particular the US stock market) has been an incredibly positive influence on the average American's 401k... Great driver of allowing Americans and beyond to share in the upside of successful companies... big reason why Americans can retire.

          Of course, it doesn't always go up...

          I think you have an oddly negative bias.

          • ai_fry_ur_brain 4 hours ago ago

            I think you have too much trust in a class of Elites that see us as pigs to be taken to the slaughter. The lindy effect isnt real, just because it has been positive doesn't mean it will continue to be that way

            The levels of greed in our society our unmatched. Planes, mansions and yachts for a few thousand people while 10s of millions struggle to buy basic medicine for their children.

        Well Apple followed being a disaster for two decades.

    • martinald 2 hours ago ago

      Let's get it in perspective though. The S&P500 market cap is currently $70T.

      Assume that Anthropic, OpenAI and SpaceX all IPO and get included in SPY with the new fast listing rules. They are likely to be worth $3-4T combined, which means 'retail' investors are going to have perhaps 5% of their portfolio in it.

      _Arugably_ that's a pretty fair allocation for retail investors to have to these "moonshot" style companies.

      Also - if any one of these IPOs don't go well; I suspect the other(s) will have to postpone, further reducing exposure.

      • xracy 2 hours ago ago

        Who invests in an index fund for "moonshots"?

        Everyone I know who invests in an index fund is doing so to mitigate the risks of things like "moonshots" which are typically much riskier investments.

        • martinald 2 hours ago ago

          Is it? I thought the idea was diversity of risk, not "mitigating risk". You clearly don't want 100% of your 401k in OpenAI or Anthropic. But you probably do want 1 or 2% of it in, to give you the long term growth potential?

          Regardless SPY is actually a pretty "risky" index fund on some measures - it pays a (very) low dividend compared to many other intl/ETF funds and is weighted very heavily towards tech stocks (atm).

          If you genuinely wanted to mitigate risk you would probably not choose SPY.

          • xracy 2 hours ago ago

            > Is it?

            Given that they've had to change the rules of index funds to allow for this, yes, this is not what people expect.

            • martinald an hour ago ago

              But the US has never had $1T+ IPOs before. And also a huge amount of enormous private companies that don't want to go public for various reasons.

              Also, the rules have changed before. It's not the first time these rules have changed.

              I see both sides of the argument (it's definitely _not_ good for 401k investors if Anthropic/OpenAI/SpaceX make huge leaps in technology that allow for far higher earnings that they aren't able to access, for example).

              But my main point is that these investors regardless would "only" have 5% exposure to these. That surely cannot be considered a systemic risk that the OP is inferring.

        Most (all?) 401k plans limit you to a pre-picked list of ETFs and mutual funds you can invest in. Not to mention the standard advice for decades has been 'broad market index fund'.

        • qznc 6 hours ago ago

          Afaik this is the first time that an IPO is big that it immediately gets a significant share of a broad market index fund. The rules among the providers are actually quite diverse, so it's complicated. The Rational Reminder podcast discussed it in April: https://rationalreminder.ca/podcast/406

          Their conclusion: It might be bad, but so be it. No need to change strategy.

          • lanthissa 6 hours ago ago

            if you want to personally manage your risk you can by taking a small short position or buying long dated puts.

            It being in the public markets is something you can deal with if you want.

            It being in private markets means you cannot choose to participate in the upside if you want.

        • mnicky 5 hours ago ago

          Good thing is that index funds don't hold stocks at market capitalization but only at free float value. So a company whose shares are mostly held by founders, employees, and strategic investors gets a weight well below its headline valuation.

          • BoggleOhYeah 3 hours ago ago

            Most don’t. The one that is the center of much of the controversy around these IPOs, NASDAQ-100, doesn’t use float adjustments.

            A lot of people have been using it to passively invest in AI (via QQQ).

            It’s nonsensical for a variety of reasons but we live an era of the stock market just being another casino…

        The filing isn’t the problem. The indices dumping into them is.

        • hellojesus 4 hours ago ago

          Agreed. Ben Felix has a video about this, I think he focused on SpaceX in it. The problem with the standard total market funds is they gobble it up right away. There are funds that do wait some period of time to purchase new ipos to let them smooth out, but I'm not sure those are typically available in 401k plans.

          Hedge funds already know broad based mutuals will have to purchase these so can sneak in before them and then sell to them for a marginal gain. Mayhaps the newest strategy for exiting is generating so much hype that you're guaranteed an exit by retail retirement funds?

      > I'm bullish on AI

      I started as being very skeptical circa 2024, became more open minded towards the end of 2025, and am becoming skeptical again now. Reason being, I interact with entrepreneurs now and I see what they hope for in AI. The universal desire seems to be "people will just talk to AI instead of me while paying me the same as before or more". This is typically covered with coping mechanisms (e.g. "I am not building a chat bot, I am building..." after which they describe a chat bot).

      I think the crash is getting more likely because the disconnect between what the technology can be used for does not match what people want it to do.

    • lanthissa 6 hours ago ago

      you cant have it both ways, the public can either have exposure and capture the upside or not.

        • ashdksnndck 6 hours ago ago

          The narrative is that inference on existing models is profitable. All of the profits and many billions of additional capital invested go into training the next model, which is some multiple more expensive to train than the last. Each new model generation also leads to more revenue growth. Newer models are more compute-efficient when distilled (so could possibly be higher margin) but also they work on longer time-horizon tasks and can make greater use of test-time compute which increases token counts. So the inference ROI on each model can pay back the cost of training it, but future growth demands put all that money and more into training the next model. The numbers we’d need to prove whether this is true are not public, but it makes sense and fits what info we do have.

          Theoretically, if training more expensive models stops resulting in better capabilities or isn’t economically viable, the labs can shift gears into making profit on old models. A lot of future growth is priced in so this would lead to a collapse in share price if it happens anytime soon.

          There’s a story out that Anthropic might be profitable this quarter. This is in one sense bad news - it means that the company wasn’t aggressive enough about acquiring capacity last year, because they didn’t foresee how fast their inference business would grow. Anthropic is now forced to make suboptimal choices about serving existing users vs. training the next model (need to scrounge for capacity by paying other players like SpaceX). And as a Claude Code user I feel like I’ve been affected by that, what with the random outages and performance degradations.

          • epolanski 3 hours ago ago

            Wait till people find out you can have the same or close to the same output at 1/100th of a price.

            You cant possibly believe we'll be just spending more and more in tokens endlessly.

            And if the margins are so good for anthropic they will collapse. There's too much competition in the field.

            • ashdksnndck an hour ago ago

              I don’t believe similar scores on small bounded tasks mean models are interchangeable. I’ve found that heavy token-burning workflows are good for my productivity (letting multiple sessions run async working of different stuff). Claude ultracode is an easy example to point to, but there are tons of harnesses out there doing similar things. I find using a higher quality model matters because it affects how far it can get unattended before heading the wrong direction. I’ve tried using the cheaper/faster models and it’s a real downgrade (or completely useless). A model that’s even smarter with longer time horizon would be even better for my productivity. I don’t think we are at the ceiling for model quality or price. My employer pays a lot for my tokens but it’s still a lot less than they pay me.

              I agree Anthropic faces some risk they could get commoditized, but on the other hand if things go well they could end up leading adoption into more industries. There are upside and downside scenarios. Recursive self-improvement is obviously an important unknown and could lead to winner-take-all.

            • gopher_space 29 minutes ago ago

              There's the "how much of my company exists in a black box controlled by some asshole" angle as well, but in my mind the biggest issue is that current models are already capable of saturating a dev in like four hours.

        • acdha 6 hours ago ago

          Yes - IIRC, Amazon was profitable on books by 1996, with other sectors following as they expanded and it was clear that they could post profits any time they wanted by slowing expansion. It was surreal through the bubble years to see “analysts” equating them with companies which were losing money on every sale with no clear way to change that.

          • madars 5 hours ago ago

            Exactly right. Even though ride sharing industry lost money in subsidy arms race and side bets it was likewise fundamentally sound in major metros since early on.

      It's more insidious than that. These IPOs aren't being rushed, they were waiting for all the pieces to be in place to force 401ks and other retirement plans to buy these IPOs.

      The most recent change was the NASDAQ adopting the "fast change rule" which allows newly IPO'd companies to be listed in the index after only 15 days of trading. This rule was decided March 30, 2026 and only came into effect May 1, 2026.

      The plan is to rapidly drive these prices up in the first 15 days, get the companies listed in the NASDAQ so funds are forced to purchase them at higher prices, then leave retirement accounts holding the bag.

        As unlikely it is to happen at scale, as a thought process - what would happen if people start selling those index funds in a mad rush? Just drives the transaction volume because those with that new money will just buy something else in the market?

        I know SpaceX, Anthropic, and OpenAI will probably be a drop in the bucket in terms of scale of these funds, (free float % etc). But, is it realistic to take the money out of index funds for a bit until the price of these new stocks come crashing eventually?

        • nostrademons 7 hours ago ago

          If people actually dumped index funds for cash en masse it would be catastrophic. To attach some numbers, MSFT averages about 35M shares in daily volume, and that includes all the market makers, HFTs, etc. BlackRock (iShares) owns 593M shares of MSFT and Vanguard owns another 482M. Together, the amount of shares that index funds own is about a month and a half of total trading volumes. I'd bet that such a crash would unfold over about 2-3 days, which brings up the specter of stocks literally going "no bid", where there are not enough buyers for every seller to sell, at any price.

          Likely the government would step in and inject cash directly into the markets to support them in such a scenario, because a broad-index stock market crash is the modern-day bank run. Retirees carry the bulk of their savings in the form of stocks; if it disappears, we'd likely face revolt.

          • gizajob an hour ago ago

            If you hit sell on a vanguard ETF and it sells on the market, then Vanguard isn’t the buyer is it? So in that situation with everyone dumping ETFs there would be a lag on the time taken for the ETF to sell and Vanguard to then dump the stocks back out in the market. It’s never occurred to me the situation where huge numbers of people dump index funds and how Vanguard/Blackrock account for that without becoming bag holders of the underlying stocks themselves.

            In any case, I’m not sure that large enough numbers of ETF holders are sitting close enough “to the button” to hit sell in the event of a sharp downturn occurring over the space of even a week or two. And a lot of them would see it as an opportunity to DCA into the dip anyway.

However, in April the methodology changed to allow stocks with either 10% FSO or approximately $3.3 billion in float-adjusted market capitalization to be eligible for index inclusion.

            But isn't that what "total market" means? I don't see how if you invest in a total market fund you could declare "except for SpaceX, Anthropic and OpenAI".

            • alemanek 7 hours ago ago

              Until recently companies that IPOed weren’t immediately added to the major indexes so there was a longer period for price discovery. This year that changed; so you have retirement funds that typically are more conservative acting as exit liquidity for these massive IPOs.

              I would have less of an issue if the inclusion in major indexes was delayed 6-12months but we are looking at inclusion within like 5 days for some of these indexes.

              • tonfa 5 hours ago ago

                The float will get bigger as you wait tho, since it's common for early investors to be locked for e.g. 6 months. You can argue it's better to smooth the entry as float gets unlocked rather than being front run by all the hedge funds in a single day on a massive capitalization.

              Mostly by having a pulse for the last 10-20 years as someone in the bay area seeing it repeatedly play out as tech IPOs get dumped onto retail investors repeatedly, including the 'good' ones. Being lucky enough to participate in IPOs makes you check these wrt when to balance IPO pop exit (weeks/months) vs long-term tax benefits of holding (2yr+).

              - The initial pop is known to be manufactured by banks, so mostly benefits insiders, so good time to diversify. I'm conservative so sold to cover effective basis or whatever risk strategy :)

              - The lockup period (6mo) is a similarly known artificial event, and studies show that

              - Tech companies take ~8 quarters of prep for the IPO as they do financial engineering to transition from VC growth-at-all-costs to public $, and I'd expect the same for whatever nonsense they pulled to juice numbers to shake out. And that's not including oddballs like the Musk alternate universe, just normal tech companies covering up EBITDA and low interest rate madness.

              - Tech is especially volatile as an industry, so even more skepticism here. Eg, the latest IPO I was involved in was a successful professional social network play, and chatgpt killed it.

            The person I was responding to was speaking to the fast-track concept, which has been a thing in CRSP indexes for a quite a while.

            The float requirement changes are directly due to these huge IPOs only placing small amounts of float on the market. Their goal seems to be tracking the market and making this change prevents them from excluding two notable companies from their indexes.

            IIRC CRSP indexes are float-weighted so they aren't going to attempt buying a ton of these IPOs anyway due to that low float.

            Again. Would I have made the change? No because placing that little float on the market isn't kosher IMO.

              These IPOs will have minuscule impact on the indexes initially. They will have a big impact if they can maintain share price in the first ranking/reconstitution after the lockup period expires.

              • BoggleOhYeah 6 hours ago ago

                They will have a big impact if they can maintain share price AND the float increases due to the lockout period expiring (ie. pre-IPO owners selling off shares).

              • largbae 5 hours ago ago

                Won't the lockup expiry increase the float on these already-included companies, forcing mechanical buying by all the very large pool pool of folks holding these index funds? Thus creating forced buyers to maintain said share price?

                • stockresearcher 2 hours ago ago

                  Every single index fund is different. They all have publicly available methodology guides; you can read them to understand how it works and to model various scenarios.

                  This particular one, the CRSP total market - which Vanguard uses for VTI - has a “modern” methodology that is thought to be very good. Once every three months they re-rank the entire market and assign weights based on the market as of a particular point in time. Then, a randomly-chosen number of days later, the fund (Vanguard) begins a weeklong reconstitution process in which they buy and sell stocks to reflect the new weights. It is intentionally a weeklong process so that the market is setting prices and not Vanguard with the size of their orders.

                  The lockup expiry happens, the market reacts, the market is re-weighted, the index reconstitutes. In that order. The price of the stock has to survive the increased float to force the index fund to buy lots more shares.

        They only go into the index if they are actually worth enough to go into the index. If they drop below a certain value they will naturally be kicked out of the index just like any other company. I.e. if they are not actually in the top 500 US companies then they will not be in the 500 index. The risk of any one company is balanced by all the other companies in the index also.

        If they really are a scam, their value will drop and they will be kicked out of the index. I still don’t understand how this means people will be “holding the bag”.

        Additionally if you really believe that they are a scam and their price will fall you can just short the stock to completely neutralize their effect on your 401k.

        • randbyte 43 minutes ago ago

          By the time they drop and being kicked out (if they do) the insiders already dumped their shares. Not to mention now all the index fund holders will rush to sell creating even more price pressure.

          Shorting (itself being a bad idea for regular investors) also breaks the mantra of passive investing, 401k or otherwise. It’s almost impossible to short right after IPO because of low float and high margin risk.

          • chasd00 6 hours ago ago

            In your 401k portal/website there's usually a setting like "I plan to retire on year X". When you set that, or something similar, there's typically a managed fund that gradually decreases risk as you approach that year. When you have lots of time before retirement you can ride the ups and downs but as you get closer the less time you have to recover from a downturn so the more conservative you want your investments.

            If you're really worried and want to be conservative tell the portal you want to retire in 2030. That will allocate your investments to something conservative and you'll be more protected from a downturn. On the other hand, you'll also be equally protected from an upswing.

          All rallies do come to an end. The fact that we all don't know exactly what will cause this one to end is exactly part of the problem and 100% doesn't mean it won't happen. Usually some external shock spooks the market and a massive sell off happens.

          So what could happen, any number of things. An obvious near term issue might be inflation increases dramatically in the US (on account of the oil shock), causing interest rates to increase - maybe dramatically - , which causes the stock market to retract. Also, the housing market is pretty much toast at the moment and an increase in interest rates might finish it off too causing a contraction there. So many ways things can break.

          But honestly, I'll tell you after it happens and it will happen. Having lived through a few of these now when everyone tells you it's a sure thing and prices go up for ever you get an inkling you are near the pop.

            Yes sure, but that statement contains zero information -- why do you believe it will end in a time short enough for the "market bubble" comments to even make sense?

            External shocks -- sure of course. Inflation problems in US -- absolutely, it's a ticking time bomb with a debt crisis looming. Housing market I don't really know anything about but I'll take your word for it.

            But all of this has been true for awhile, and could have been stated with equal veracity over the course of the last 5 years at least. Your beliefs shape your actions; so why does this belief shape actions any differently than it has earlier?

            Again totally true, I have also lived through them and expect more. But "these companies are IPO'ing because they know the market will pop" is kind of the thing that I was trying to address. For all the signals of market danger, there are plenty of optimistic signals all over the data. Growth is pretty robust across all sectors today.

        • torben-friis 7 hours ago ago

              Token cost might be sustainable but still not profitable enough to make up for the costs of either training or the investments gifted away until it became profitable. They also might have no relevant moat that allows them to enshittify enough. But mainly, they are in "I need to kill whole industries to be worth it" tiers of investment.

              • aspenmartin 6 hours ago ago

                > But mainly, they are in "I need to kill whole industries to be worth it" tiers of investment.

                Yes agreed. Coding is a pretty big industry though in and of itself. Same with healthcare, legal, etc etc etc. Of course we have zero model today that can seriously kill an industry, but if you look at (1) how good things are today (insanely fast and rapid adoption) and (2) robust performance trends from many complimentary sources, it's kind of inevitable and I haven't really heard a coherent steel man argument for why "killing whole industries" is somehow a far-fetched idea.

                > still not profitable enough to make up for the costs of either training or the investments gifted away until it became profitable.

                Regardless of the weeds of the economics today, you have a clearly valuable asset that at the very least already a must-have for enterprise and will become even more essential over time. There is token economics that either already do or will make sense. You will have some sort of marginal cost + profit margin that things will stabilize at. You can pay a premium for high quality frontier models. "But it costs more in R&D to fund this!" ok but then token costs will increase. Why is this some sort of death knell?

                  >it's kind of inevitable and I haven't really heard a coherent steel man argument for why "killing whole industries" is somehow a far-fetched idea.

                  They don't only require "good enough to kill industries" (which is doubtful but certainly feasible), that's just step one. I think about it in terms of potential failure modes:

                  - if models don't reach worker-substitution levels, they fail

                  - if models reach that level, but it's too expensive to run and a worker's still cheaper, they fail

                  - if models reach that level, but the resulting tech is cheap enough to use, they fail (since open models can compete)

                  - If the models work but there's social rejection leading to regulation (due to mass unemployment for example), they fail

                  - if the models work but there are significant deal breakers (like a fundamental inability to keep them safeish to use) they fail.

                  So it's not really a single AI killer reason, it's more that the success case requires things to land in a very specific future where models work, and they're cheap enough, and expensive enough, and valuable enough, and exclusive enough, and safe enough, and...

                  Each "and" is a multiplier reducing their chances, and there's a ton or factors. Not imposible, but not where I'd put my money.

                  • aspenmartin 3 hours ago ago

                    If 1B people consume via personally or their employer on average $100/mo of tokens or services that solves the problem right there and that is not inconceivable whatsoever and feels like an underestimate. Repayment doesn’t imply you have to build an end to end replacement of an industry.

                    This also negates this whole like “you have to completely replace a human” fallacy. Why do you need to replace a human? Why not just increase the value each human brings you?

                    The model of open weights has been around for awhile. You have frontier labs releasing them. They are powerful and capable and track yet lag frontier models. Without massive government subsidies from probably China who did something similar with manufacturing I don’t get the idea of OSS somehow toppling the entire industry of frontier models. How would this happen? Did demand for frontier models drop after GPT-4? GPT-5? Because the cost of GPT-4 perf is maybe 100x cheaper today. You can always pay a premium for a better model (more data spend with proprietary data sources, more compute for training, more thinking budgets), and in the end, things will either go to a monopoly or prices will stabilize around the marginal costs.

                    Also safeguards are always important. They are thorny fundamental horrific problems and I can tell you there will be a hellscape of pain as people figure out the trivial ways to do bad things with some of the worst security practices we’ve seen. But I don’t get why this is a dealbreaker, we are using these systems everywhere and in loads bearing environments, today, and reliability and hallucination rates continue to increase / decrease.

                      0.15B is the full actively employed population of the US. 0.2 extra for the full EU, and we're barely making a third of the needed numbers, and this is assuming that the guy cleaning the street or the plumber will have a 100 bucks subscription just because - not to mention that a hundred bucks is 10-20% of median monthly income in many countries, even some EU ones.

      That is not why you are seeing a deluge in listings. It takes 1-2 years to make a company IPO ready and is a massive operational headache, and the controls needed take multiple quarters to implement.

      The reason you are seeing a boom in IPOs versus 2023-25 is because a large portion of funds that are from the 2016-20 vintage are about to hit the 10 year mark when LPs need to be made whole.

      This means you need to exit your investments either with an additional round, an acquisition, or (the most common approach for growth equity which is what series D and later rounds are) IPO.

    Curious how someone with a 401k, who didn't want their retirement to be used by these companies to buy at an inflated price, would go about opting out of this.

    Typically I just have my 401k in an index fund so that things have to become established before they're added. This seems like it's circumventing that, and I would be inclined to vote with my wallet. But everything around 401k index funds that I see are very opaque, so it's not totally clear to me how I would avoid this if I wanted to.

    • thunky 28 minutes ago ago

      If your 401k offers it you could look into an "equity income" fund. Not for the dividend income per se, but because these a are big stable companies with a track record of paying dividends.

      Also, consumer staples are known for holding their ground during downturns.

      But the general advice given is to accept that you probably can't beat the market so don't overthink it and just own the whole thing.

      Also keep an eye on expense ratios. A lot of 401k providers gouge you on anything but the basic funds. So you'd have to beat the market by that much more.

    • benl an hour ago ago

      Technically I think this would be fairly straightforward. You could keep the index fund and then short the stock you believe is overvalued, to the degree it's weighted in the index fund. That would give you stock market exposure equivalent to the index without the company you don't believe in.

      But I would strongly advise you to NOT DO THIS.

      The above position makes it explicit that your thesis involves shorting a stock that could go through the roof in value. That emphasizes what a risk you're taking with your thesis. If your typical investment approach is to just buy index funds, then carry on just buying index funds and let the market do its work.

      By the way, if SpaceX, Anthropic, OpenAI etc were to be excluded from the indices, then professional investors would just start a trade the inverse of the one I outlined above - i.e. they'd start shorting your index fund to the extent it was underweight in those companies, in order to profit off the exclusion of those tickers from it.

      If you're in this for the long term (which I assume you are given this is your 401k), don't try to second-guess the market short-term.

    • 0xbadcafebee 2 hours ago ago

      You can pick funds that have little exposure to tech, which probably isn't what you're asking, but is a safer bet than being too much in tech:

        Just because it's a bubble doesn't mean money can't be made.

        If you're worried it and the risk involved, perhaps go from 100% equities (100/0) to an allocation that has some bonds (90/10, 80/20, etc). Rebalance as things get out of whack.

        There are products that do this rebalancing for you: target-date funds that increase bond allocation as you get closer to retirement, or fixed-allocation all-in-one funds (VASGX, VSMGX; CA: VEQT/XEQT).

        Having some bonds and rebalancing would have saved US domestic investors in the so-called Lost Decade of the '00s:

      "Going public" means something completely different now, especially for these companies in the news (Anthropic, OpenAI, SpaceX, etc).

      Going public used to mean selling a portion of your company for the capital required to grow. Ideally John Q. Public buys stock, the company grows, and they can sell the stock for more money.

      These companies already have the capital required to grow from private investment, and already grew; they're behemoths. The act of "going public" are those private investors using the public market to cash out their investment. The exponential growth the public buyers are expecting to see has most likely already happened.

      You pretty much always do a late-stage private round shortly before an IPO, that is the standard.

          Most stocks suck:

          > We study long-run shareholder outcomes for over 64,000 global common stocks during the January 1990 to December 2020 period. We document that the majority, 55.2% of U.S. stocks and 57.4% of non-U.S. stocks, underperform one-month U.S. Treasury bills in terms of compound returns over the full sample. Focusing on aggregate shareholder outcomes, we find that the top-performing 2.4% of firms account for all of the $US 75.7 trillion in net global stock market wealth creation from 1990 to December 2020. Outside the US, 1.41% of firms account for the $US 30.7 trillion in net wealth creation.

          > Four out of every seven common stocks that have appeared in the CRSP database since 1926 have lifetime buy-and-hold returns less than one-month Treasuries. When stated in terms of lifetime dollar wealth creation, the best-performing four percent of listed companies explain the net gain for the entire U.S. stock market since 1926, as other stocks collectively matched Treasury bills. These results highlight the important role of positive skewness in the distribution of individual stock returns, attributable both to skewness in monthly returns and to the effects of compounding. The results help to explain why poorly-diversified active strategies most often underperform market averages.

          * https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2900447

          Further, over ten years, most individual stocks under perform a market index (even more so if stock was initially a top performer):

          > […] Since 1926, the median ten-year return on individual U.S. stocks relative to the broad equity market is –7.9%, underperforming by 0.82% per year. For stocks that have been among the top 20% performers over the previous five years, the median ten-year market-adjusted return falls to –17.8%, underperforming by 1.94% per year. Since the end of World War II, the median ten-year market-adjusted return of recent winners has been negative for 93% of the time. The case for diversifying concentrated positions in individual stocks, particularly in recent market winners, is even stronger than most investors realize.

Is that true at all? I'm sure the situation is much more complicated, but I do wonder how to figure out how much I'm affected.

      • lbrandy 9 hours ago ago

        There is a huge amount of misinformation on this topic, including in this thread, at the minute.

        Some index funds have a very long horizon before they include them (e.g. a year). Others are "fast-tracked" (e.g. notably VTI). Most of those, however, are float-adjusted, so only the stock available for trade is considered part of the marketcap. So e.g. VTI / VTSAX will buy spacex relatively quickly after the IPO but at the float-adjusted weight of ~$75B because that's the % of stock available.

        If you care alot about this, now is the time to understand how your index fund treats IPOs wrt to delays + float adjustment.

        • avensec 8 hours ago ago

          Do you have any suggested reading references?

          Specifically, I do a typical 3FP and own VTSAX, but I don't read bogleheads or anything. True set-it-and-forget-it, but I do want to read more if things are shifting.

          • lbrandy 8 hours ago ago

            You should not trust me, but here's my understanding. I wish there was a really good writeup somewhere to explain this authoritatively but I'm not sure there is one. Would also love to see one. Frankly vanguard should do it.

            VTSAX (and VTI) follow the CRSP index. This is float-adjusted but they likely will be fast tracked (these are two separate rules in how this index chooses to weight things and participate in new stocks). At ~5% float, these companies will be in the 50-100B range. So under all those assumptions, they'll be bought quickly but represent less than 1% of VTSAX (until they float more shares on the public market).

    With SpaceX, OpenAI, and Anthropic, we're likely to see 3 of the largest IPOs ever (by a wide margin) this year. Will existing institutional investors trim other positions to allocate a lot of capital for these mega listings or is this not a concern?

    • thewebguyd 9 hours ago ago

      Most likely. Funds generally don't have much unallocated cash, they operate fully invested, so three huge IPOs will force an asset rebalancing which can cause some liquidity drain from the rest of the market.

      Plus as insider lockup periods expire, that's a ton of dollars pulled out of the market and into safer assets. It's going to be a huge net exit of capital.

      I'd expect a lot of volatility and pretty heavy downward pressure across the rest of tech.

      • bluGill 9 hours ago ago

        Maybe. If you read the fine print they are not. They have the goal of matching the index returns, but they never say anywhere they have exactly the stocks in the index.

        Index funds all make active choices and often hold companies not in the original index. They are more passive than a traditional funds that buys and sells all the time, but they still make active choices. When an index changes stocks they can look up the price - but the funds mirroring the index need to make real trades that if not carefully done will change the value of the stocks (and cause the fund to under perform the index), so index funds have plans to prevent this. Compared to a traditional fund an index fund looks passive and there is much much less for the manager to do - but that doesn't mean the managers do nothing.

      • chilipepperhott 9 hours ago ago

    As a layman external observer, this seems a bit rushed to me? I know there's a race amongst the frontier AI labs, but I don't quite understand the rush (apparently there is still a lot of money to go around), so as some comments imply, it does look like "our financials look good right now let's strike while the iron is hot!"

    I do think Anthropic's business has very good long-term prospects, but the current run rates are not sustainable and they know it which is why they, more than OpenAI, are under higher pressure to IPO. Some things to consider:

    1. This was surprising to me, but enterprises Claude Code (and Codex) plans are billed on token usage at API rates. I was expecting lower rates for volume subscriptions. This explains their huge spike in ARR, but I expect competitive pressures will soon come into play, especially as companies start to get more budget-conscious. Specifically...

    2. Tokenmaxxing is finally encountering the inevitable pushback. My theory is it was an effort to incentivize devs to experiment and figure out ways to get productive with AI by throwing money at the problem, which was always going to be a short-term dynamic. Companies are going to be much more intentional about token budgets (especially as Anthropic is apparently now asking for volume commitments for enterprise plans.) Smaller, open-weight models may start looking much more attractive.

    3. I've said before but I think Anthropic severely underestimated their own popularity and corresponding demand for compute and has to enter costly deals to acquire capacity to keep Claude's 9's above GitHub's, even as they alienated customers with short term tweaks to optimize usage. These deals will eat into their margins and Claude's problems likely pushed customers to competitors, the effects of which could take time to be more evident.

    So maybe whatever looks good on their financials right now is time-limited, and the current boost may start petering out at some point, which may influence when OpenAI files their own IPO.

      S&P 500 requires trailing 12 month profitability to be on the index. We won't see any of these on the S&P for at least a year or more.

        The profitability requirements are potentially being dropped. Consultation just closed and may be implemented as soon as next week.

        I thought S&P also changed the rules on this one

          Reading these messages is getting me discussed. Is there any fund/index fund that is not breaking the rules to allow easier pump and dump from big players?

      Only Nasdaq has changed their inclusion rules (at least for now).

    of course. do it now while they have the users. in a year when everyone has laptops with 128gb+ running models locally, anthropic stands zero chance. same with openai. i dont even use openai anymore. this will be one of the biggest crashes in history.

    Did mythos write the S-1? It better not have been a human given the amount of hype they are pushing.

    Time to short the market. We are at peak bubble.

      The market can remain irrational longer than you can remain solvent.

      post your position for all to see if you're so confident. Time in market is way better than timing the market. I'd rather ride through a downturn, buying at the same pace i always do, and come out the other side than try to time it. Been there done that and i got burned every time.

      Shorting when there is a mania is way, way too risky

      The amount of actual, hard cash revenue these companies are making is a different ballgame from the dot-com bubble.

        Cisco was making loads of hard cash revenue during dotcom.

      I've seen this comment on HN at least 5 times already.

        I've been seeing this sentiment since I got into professional software development nearly 20 years ago.

      This is actually the pin everyone was looking for that will pop this AI bubble, including the token cost falling in China and the release of open models that are good and run locally.

        It could be, but the market could bounce right back. And if it does, it's hard to know who will emerge stronger. Anthropic could end up like Amazon, or it could end up like Yahoo.

        Where are these open models that are as good as GPT and Claude and run locally?

  • kenyuz 9 hours ago ago

    Every post anthropic generates feels like misdirection and bad summarization using AI. There is no sense of who the audience for this post is for and includes a lot of redundant information.
