alt Hacker NewsIt'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.

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.
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?
Very few 401ks offer the NASDAQ 100 as an investment option. Last I checked it was <1%.
It is not going to take 15 days for short selling hedge funds to right-price these IPOs. It is going to take something closer to a few seconds.

Dumb question: why couldn't retirement accounts simply not purchase these?
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?
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.
How do these people sleep at night coming up with schemes like that?
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.
If you believe this is going to happen you can change the allocations of your retirement plans.

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. […]
