S&P 500 Rejects SpaceX, Also Blocking OpenAI and Anthropic
Ars Technica AI·4h ago·Business
S&P Dow Jones Indices will not shorten the 12-month seasoning period for newly public companies or waive profitability and public-float requirements based on size.
That blocks a fast path into the S&P 500 for SpaceX after an IPO, and would also affect OpenAI and Anthropic if they list.
The decision delays potential passive-fund buying and signals that high valuations alone will not override traditional index rules.
