    If OpenAI and Anthropic eventually become public companies with trillion-dollar valuations, it will be interesting to see if their company ethos remains the same. With that much purchasing power, it's very tempting to gobble up competitors and raise prices.

    • johnQdeveloper 7 minutes ago

      They already do both.

      The real competition is coming out of China right now and I doubt the Chinese government is going to let them buy out their "fast follower" AI companies that are consistently 6-12 months behind in terms of quality. That said, I'm factoring quality as in Opus 4.5/Sonnet 4.5/GPT-5.5 as break points since I haven't really seen an improvement since that point when using AI.

      The question is not "if" they will lose their ethos but "how long will it take".

      • pton_xd 18 minutes ago

        If "Open AI" was their ethos, it was lost immediately. I'm not sure what the ethos of Anthropic is.

      I’m curious which labs will start producing hardware be it robotics, consumer or commercial devices, chips, energy infrastructure or transforming shipping crates into housing for displaced and jobless humans. O_o

    • blmarket 30 minutes ago

      IPO won't lose their ethos. Competition out from their duopoly will.

      • seanp2k2 13 minutes ago

        Who else right now is making competing models that are roughly as capable? Now factor in hardware availability / future delivery contracts and capital requirements for building datacenters and running new training. If you're trying to compete and lease all that with VC money or loans, good luck actually competing.

      > if their company ethos remains the same.

      What? In what way would the change? They are already raising prices..

    SpaceX submitted an amendment to their S-1 today[1]

      Are we in a race to see who can pop the bubble first?

      • FuckButtons 27 minutes ago

        They all know it’s coming, if it pops before they ipo then they don’t get their billion dollar payday, they have every incentive to move quickly.

      • roadside_picnic 28 minutes ago

        As you likely know, rules have recently been changed that basically force many 401k funds to invest in these IPOs while simultaneously having a relatively small number of the initial IPO to be sold to the public forcing the funds to by at inflated prices.

        The bubble won't pop until these retirement accounts of have been raided.

  • cmiles8 36 minutes ago

    There is a mad rush to get these IPOs out the door before the market sneezes.

    • roadside_picnic 23 minutes ago

      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.

      • noelsusman 3 minutes ago

        Very few 401ks offer the NASDAQ 100 as an investment option. Last I checked it was <1%.

      • giarc 7 minutes ago

        I get the sentiment that this is unscrupulous, however, isn't 15 days enough time to find the right price? Or will that not really happen until first quarterly earnings report, which will not occur within that 15 day window?

      • chinathrow 9 minutes ago

        How do these people sleep at night coming up witj schemes like that?

      • cdelsolar 4 minutes ago

        If you believe this is going to happen you can change the allocations of your retirement plans.

    • gonzalohm 30 minutes ago

      And oh boy do they make sure everyone knows that they are doing an IPO

  • freediddy 42 minutes ago

    This is the first time I've seen a Public, Confidential S-1 filing.

    • Maxatar 28 minutes ago

      It's the contents of the submission that are confidential, not the fact that they are submitting.

      The contents themselves contain a lot of detailed information about the internals of the company including financials, revenue, ownership details etc... those details are what's confidential until the SEC gives its approval, at which point the public can then review the document.

      • outside1234 21 minutes ago

        What this means it that it won't survive scrutiny, so better hide it so that there is only a small amount of time to do it.

        • jmtulloss 10 minutes ago

          Why do you think this? Confidential filings before an IPO are standard practice.

    • Sol- 40 minutes ago

      I suppose they announced it because the fact that they submitted it would leak anyway.

    • iLoveOncall 29 minutes ago

      That's how you know it's purely marketing and they're not actually going public.

      • 0123456789ABCDE 20 minutes ago

        excuse me. what am i being sold, in this so called marketing?

        • iLoveOncall 14 minutes ago

          You? Nothing. Private investors? The dream of an IPO.

      • sh34r 22 minutes ago

        Given how often these get leaked (see Palantir + SpaceX) and the cost of preparation, why would you ever file an S-1 unless you were serious?

        • iLoveOncall 13 minutes ago

          Because you want another funding round but you will get it only if investors think they're going to get their money back soon.

  • 40acres 17 minutes ago

    After years of companies refusing to go public (looking at you Stripe), it's almost refreshing to see a hyped tech go actually IPO.

    • parthdesai 5 minutes ago

      Is it actually refreshing? It's actually refreshing to see Stripe staying private for so long. That means, they have a sustainable business model, and can take on projects that might benefit users in the long term despite negative short term consequences instead of focus on growing at all cost for the most part.

  • sschueller 28 minutes ago

    Where will it be listed? I am considering selling all my index ETFs in those markets until the this blows over.

    • PUSH_AX 25 minutes ago

      Time in market > timing the market.

      • rottencupcakes 9 minutes ago

        It's this sort of mentality and the prolitferation of passive investing that gives these companies the opportunity to pass the bag.

  • eamag 21 minutes ago

    why did they raise 3 days ago? What's the benefit of doing this instead of going public right away? If it's just cash to pay for GPUs, can't they issue bonds or something?

    • Maxatar 11 minutes ago

      You pretty much always do a late-stage private round shortly before an IPO, that is the standard. The goal of the late-stage funding round is to give a better idea of how much capital can be raised by the IPO. It helps reduce uncertainty about expectations of what the company is worth before going public.

    • 44df 16 minutes ago

      Pump up the valuation baby.

      Price setting.

    • gedy 11 minutes ago

      IPO isn't really about "raising money for the company" any longer, unless one means raising the money in their wallets so they can take the money and run.

  • ssgodderidge 44 minutes ago

    Can someone help me understand how its "confidential" if they blog about it? Perhaps they simply mean the details of the S-1 are confidential for now?

    • kylecazar 43 minutes ago

      The contents are confidential. They are just announcing they submitted it.

    • ConnorBoyd 43 minutes ago

      The S-1 itself isn't made public in a confidential filing.

  • ch4s3 44 minutes ago

    I'm curious to know if they generated this with Claude and what the prompt looked like.

  • chinathrow 44 minutes ago

    Expect the token price to correlate with the stock price.

  • hubraumhugo 39 minutes ago

    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?

    • nemomarx 37 minutes ago

      At least all the index funds are obligated to, right?

      • qwytw 28 minutes ago

        Based on current rules they wouldn't included in the S&P 500 for at least several years even based on optimistic scenarios.

        Of course IIRC they looking into tweaking the rules to allow some handpicked extremely unprofitable companies in, due to "reasons"....

      • bluGill 24 minutes 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 31 minutes ago

        Most index funds wait for at least a year before adding a new listing. The only exception that I'm aware of is QQQ and SpaceX.

        • nemomarx 16 minutes ago

          If space x gets an exception, why wouldn't anthropic?

        • qwytw 27 minutes ago

          Technically they couldn't be added to the S&P 500 etc. until they become profitable.

      • nly 31 minutes ago

        Index funds follow indices and often only rebalance quarterly

      • DenisM 27 minutes ago

        company must have a history of profitability before being included in the S&P 500

      • outside1234 19 minutes ago

        But only the amount the company floats for many index funds. So in the case of SpaceX, they are only floating 5% of the company. So the number of shares something like VTI has to buy is much smaller than the total market cap (5% of it).

      • whateveracct 36 minutes ago

        you and me will all be left holding a small cut of the bag

  • outside1234 22 minutes ago

    Got to dump this on everyone's SP 500 index fund before people figure out that there is a 95% drop in token usage when they are metered.

    • dcre 21 minutes ago

      They are metered. That's why their ARR went from $9B to $45B in 6 months.

  • kypro 38 minutes ago

    What does it mean to submit confidentially – what's the process there? I assume it be made public when approved by the SEC?

    • Maxatar 30 minutes ago

      It means that Anthropic has submitted a document that it intends to share with the public in order to solicit public investment. This document includes details about its business, financials/revenue, ownership structure, risks, etc...

      The document itself is what's confidential until the SEC approves it, at which point Anthropic will release that document to the public and IPO.

  • rvz 42 minutes ago

    Of course that fundraise was the last one: [0], everyone getting ready to dump their pre-IPO shares on to you as China catches up with their open models.

    Better to do it now than to wait a day longer and the tokens are not getting any cheaper here.

    Obviously OpenAI will file for IPO certainly this month, or even this week in response both SpaceX, and Anthropic.

    Then AGI will then have been achieved externally.

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

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

    • rvz 34 minutes 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.

      • bensyverson 29 minutes ago

        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.

      • bjtitus 24 minutes ago

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

  • kenyuz 41 minutes 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.
