SpaceX inclusion in the S&P 500 is delayed as S&P Dow Jones Indices declined to relax megacap IPO rules, delaying passive inflows. Eligibility requires 12 months of trading, US profitability, and a 10% free float. SpaceX meets none ahead of its expected June 12 debut. The index provider will maintain standards, unlike Nasdaq and FTSE Russell, which have eased requirements.
