S&P 500 rejects SpaceX, also blocking entry for OpenAI and Anthropic

# S&P 500 Says No to SpaceX's Fast Track SpaceX wanted special permission to join the S&P 500 index quickly so it could tap into the trillions of dollars that retirement funds and investment accounts automatically invest in index companies—but the S&P 500 rejected the request. This decision also blocks a similar shortcut for AI companies like OpenAI and Anthropic when they eventually go public. Some investors are relieved by this, since it keeps retirement savings from getting too heavily invested in SpaceX's risky bets on space ventures and AI data centers.
