S&P 500

S&P 500 rules block entry for SpaceX, OpenAI, and Anthropic

The S&P 500 index committee declined to waive profitability requirements for SpaceX, a decision that also effectively bars OpenAI and Anthropic from index inclusion. The ruling reflects the index's existing rules requiring companies to demonstrate profitability before joining. This has strategic implications for AI lab valuations and public market access, as index inclusion typically drives significant institutional investment.
