S&P Dow Jones Rejects Fast-Track MegaCap IPOs, Delaying SpaceX Entry

S&P Dow Jones Indices has rejected proposals to fast-track mega-cap IPOs into the S&P 500 and related indices, preserving the standard 12-month seasoning period. The decision, following its June 4 consultation, blocks an estimated $13.4 billion in passive inflows for SpaceX until at least June 2027. While broader total-market indices will see targeted eligibility tweaks effective June 8, S&P maintained its profitability, float, and listing requirements, contrasting with Nasdaq and FTSE Russell's shorter windows. The move upholds index principles over market-cap exceptions.
