SpaceX has not been added to the S&P 500. They asked for the rules to be waived. S&P said no. I don't understand this article.

S&P 500 didn’t change their rules but other indexes have.

Q: What is the purpose of modifying the liquidity and seasoning requirements? Could this change result in the inclusion of illiquid securities in the index?

A: Most indexes require a liquidity threshold for new constituents, often as a minimum share count or average daily trading value. For the Nasdaq-100®, securities must have a three-month average daily traded value of at least $5 million. Since only very large companies – typically with full market capitalizations over $100 billion as of March 2026 – would have qualified for fast entry, they are expected to easily and quickly meet this requirement. However, an average daily traded value of at least $5 million from the time of listing will still be required for fast entry candidates. Many indexes have included seasoning requirements to ensure that traditional IPOs undergo price discovery and stabilization before being included. These requirements were originally intended to prevent small or little-known companies from entering too soon. However, there is now a trend toward IPOs being larger and more mature than in the past. Companies expected to meet the fast entry threshold are likely to be among the world’s most significant and well-known firms. High investor interest and trading volumes should accelerate price discovery, further supporting a shorter seasoning period. Note that the seasoning period for companies outside of the Top 40 remains at three months.

Several indexes have changed not just Nasdaq, but it’s one more people have heard about.

Nasdaq isn't super relevant.
Sure but it’s not the only one. Add in SPY, QQQ, and IWM Force Index Funds and the percentage of Americans buying SpaceX early due to rule changes looks bad.

Edit: Ops SPY didn’t change their rules.

SPYis sp500 is it not? Why would they include it?

For others like qqq it has no bearing to be frank. It follows the nasdaq 100. Maybe an argument that the extra few months would have allowed more price discovery but I am not so sure.

Also CRSP, which is the index used by US Total Market funds and many Target Date funds.
CRSP is float-weighted!
float adjustment results in any CRSP tracking fund/etf having a $10,000 investment being approximately $17 worth of SpaceX. This isn't a real problem the media is trying to push it as.
Less informed journalists heard about it after we did and then decided to publish what they learned on twitter.
Rage bait article or the author is just misinformed
Firms or funds, don’t care, want to put money in anyway…
