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.
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.

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.
Dumb question: why couldn't retirement accounts simply not purchase these?
Or one that just imposes a reasonable waiting period on adding newly-IPO’d listings.

VTI in turn is the primary holding of most of Vanguard's Target Date retirement funds, which are widely held in 401ks.
Edit: oh looky did I inflame the PE simians?
And there are plenty of ways to manipulate the price, such as issuing a low float to a hyper hyped stock..
Meanwhile some of these companies are also lobbying to be able to only have to submit annual or biannual earnings reports, too.
Everyone is looking for multiple ways to leave the dumb money holding the bag.
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.
There's maybe, at best, 1% of the country even aware that this might be a problem.
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.
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.
Marketing only takes you so far in creating noise.
Its weird seeing this focus on bench marks again - PC's did this for quite some time. But in the end it came down to - what does all this additional horsepower let you do? Oh create interesting apps, multi-tasking etc. Which was really the value-add.
What? In what way would the change? They are already raising prices..

The bubble won't pop until these retirement accounts of have been raided.
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....
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.
Would it crash other company stocks so that investors start selling and purchasing Anthropic shares, or how does it work?
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.
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.
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).
