- FTSE Russell's rule changes allowing faster index inclusion for IPOs, including SpaceX, could drive significant inflows into newly listed companies. This 'fast entry' rule, mirroring NASDAQ, may pressure other index providers like S&P to follow suit. While primarily impacting global and US indexes, it signals a potential shift in how large IPOs are integrated, creating demand for index-tracking funds and potentially impacting liquidity for existing investors.

New rules are:
(1) IPOs are eligible even with less than 5% free float, as long as the free float meets the minimum requirement within 12 months after IPO
(2) IPOs with large market capitalisations will be included on the index (and bought by index funds) in 5 trading days after listing, under its "fast entry" rule.
This follows NASDAQ that has already changed its index rules. Watch as S&P follows suit.
