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.
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'.
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.
> 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.
Official justification, and other changes besides timeframe, e.g.:
> First, eligibility and company size. As multi‑class share structures have become more common, we now consider both listed and unlisted shares when determining eligibility and ranking. This allows the index to reflect a company's full economic size, while index weighting remains based solely on listed shares. This change affects who qualifies for inclusion, not how constituents are weighted.
> A new method to calculate the market capitalization of companies to determine their eligibility for inclusion in the index. It involves adding listed stock and unlisted shares that are part of different share classes. Scrapping a rule that requires companies to float a minimum 10% of their shares. Companies with a low float will receive a lower weighting on the index. […]
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?
>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.
Dumb question: why couldn't retirement accounts simply not purchase these?
almost all 401k plans offer funds based on s&p 500, not nasdaq/russell others. s&p has also halved their trading days requirement from 1 yr to 6 months, but that's still sufficient to be past the post-ipo lock-up period.
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?
This has been a thing in the CRSP indexes (ie. the benchmark for Vanguard’s VTI) forever. As long as it meets float and cap requirements, it’s inserted into the indexes five days after trading begins.
It makes sense. They intend to track the market as it is.
Though, you can definitely make the case that the popularization of index funds has allowed their holders to essentially become patsies to hype IPOs.
Very true. Anthropic just raised money at the end of last week.
There's no way they could have done that without telling those investors the S-1 was prepared and awaiting their signature on the round before they hit Submit, so to speak.
Is there anything structurally to prevent a super wealthy buyer from guaranteeing this essentially -- moving money and debt around in order to essentially put a floor under the stock and guarantee buy rates until the retirement fund index purchasers have time to absorb all the shares at the artificially high price? Feels to me like this is almost guaranteed to happen -- ...
OpenAI, SpaceX, and this IPO: I don’t think there’s enough liquidity for all of them. Investors may pull money out of other investments, and hopefully that doesn’t cascade into a full market crash.
Anthropic unlike OpenAI has reached an operating profit of 559 million, which is really telling. They've also been migrating enterprise customers to API pricing, which is likely part of why they've become so profitable.
Exactly. Incredibly hard to understand what hard, non-headline-quoting, steel man arguments there are about how exactly the market will hiccup. And as if all of the AI companies somehow know this and are looking to IPO themselves out when anthropic revenue is growing > 10x per year for multiple years. Feels like a massive disconnect between “this will all implode” people and any real numbers.
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.
> Are we in a race to see who can pop the bubble first?
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:
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.
And as suspected, the Anthropic deal is not recurring revenue, its just a think they can cancel anytime with 90 days notice...Release the bad news slowly and when people are looking somewhere else...
SpaceX AI segment lost about $2.5B from operations in Q1 2026 on $818M revenue...they are burning dollars. Musk controls about 85% of voting power through supervoting shares, and cannot be fired...go IPO buyers...nothing like economic exposure without control....
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.
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.
You speak so authoritatively about quality and performance of these models, yet there are no quantitative metrics that correlate to real world outcomes that indicate that the quality and performance of these models is anything but subjective noise and classic benchmark nonsense.
A company consumed half a billion dollars worth of tokens in a month and nobody noticed anything until the bill came due.
Tha $500m dollars is roughly equivalent to 2000 people working for a year or 500 people working for four years, they can and would accomplish a lot if they worked in companies that add value to the economy by solving real problems.
I’m curious which will start producing hardware be it robotics, consumer or commercial devices, chips, energy infrastructure or transforming shipping crates into housing for jobless humans. Maybe even tanks of gel with arrays of humans in suspended animation reading our biometrics, thoughts, pumping in nutrients and training on the data. O_o
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.
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.
Becoming public allows everyday people to access the wealth generation machine your created.
Sometimes I think that the endless cynicism around corporations that exists online is the real ploy by capitalists to keep people poor. It seems to be pretty damn effective at making people allergic to claiming their slice of the pie.
"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.
Stripe seems to be doing fairly well as a private company. They continually offer liquidity events for employees to cash out, while also retaining less pressure for hypergrowth from outside activists and investors.
I think this IPO will be the real test of whether the concept of a Public Benefit Corporation actually holds up in practice. Don't mess this up, Anthropic.
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.
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?
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.
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.
I've heard of the changes to the NASDAQ rules and I somewhat get how they make it so these stocks are included in index funds earlier than before. As far as I know, NYSE and others haven't done the same change so index funds there are "safe", i.e. will include the stocks only after a longer period, implying that it will have settled in value by then. 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.
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.
Really seems that this entire industry has been told it will get a MASSIVE bailout. And with Fink basically confirming so means, Hillary was right? Trump is a tyrannus dictator?
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?
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.
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.
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).
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.
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.
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.
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.
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.
Can't see the relevance of this comment to the post. You can do a Google search for "confidentially submits draft S-1 to the SEC" to see other examples of companies announcing these submissions and they're all written in the same way.
It's just a standard/template that most companies reuse.
Is there any real reason to have generated announcements anyway? You could get more polished text with some copy editors and I can't imagine cost is really a big concern for it.
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.

Right in time to get rich and externalize any fallout.
Really seems that this entire industry has been told it will get a MASSIVE bailout. And with Fink basically confirming so means, Hillary was right? Trump is a tyrannus dictator?
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?
The contents are confidential. They are just announcing they submitted it.
The S-1 itself isn't made public in a confidential filing.

so we shouldn't talk to humans when an ai can give an answer?

Expect the token price to correlate with the stock price.
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?
It also means the equity in any 2021-2023 minted unicorn is worth zero.
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.
At least all the index funds are obligated to, right?
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"....

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.
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.

company must have a history of profitability before being included in the S&P 500
Index funds follow indices and often only rebalance quarterly
you and me will all be left holding a small cut of the bag
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).
Who’s going out of the gate first, Anthropic or Space X. Sequencing probably matters more than it should.
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.
They are metered. That's why their ARR went from $9B to $45B in 6 months.
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

Only Nasdaq has changed their inclusion rules (at least for now).
What does it mean to submit confidentially – what's the process there? I assume it be made public when approved by the SEC?
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.
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.

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.

And you can consistently beat the market as long as passive index investors believe in efficient markets.

> Time to short the market.
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?
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.
Can't see the relevance of this comment to the post. You can do a Google search for "confidentially submits draft S-1 to the SEC" to see other examples of companies announcing these submissions and they're all written in the same way.
It's just a standard/template that most companies reuse.

> This announcement is being published under Rule 135 of the Securities Act of 1933
It's a required public disclosure following a format traditionally used in mandatory public disclosures.
Is there any real reason to have generated announcements anyway? You could get more polished text with some copy editors and I can't imagine cost is really a big concern for it.
It is possible that they are dogfooding
It's a legal notice, what are you talking about?
