S&P will NOT be changing their inclusion rules for MegaCap IPOs like SpaceX

[S&P Dow Jones Indices Consultation on Treatment of MegaCap Companies - Results - Jun 4, 2026](https://press.spglobal.com/2026-06-04-S-P-Dow-Jones-Indices-Consultation-on-Treatment-of-MegaCap-Companies-Results)

There has been a lot of doomerism regarding the SpaceX IPO and how SP500 is changing their rules, causing people to go so far as to sell off their portfolio to avoid investing in SpaceX. The S&P just released their official review of these rule changes and have decided NOT to fast-track SpaceX (and other mega-cap IPOs).

This means the earliest SpaceX could be eligible to join the S&P 500 is June 2027.
