S&P 500 rejects SpaceX, also blocking entry for OpenAI and Anthropic (arstechnica.com) AI

S&P Dow Jones Indices rejected SpaceX’s request for accelerated entry into the S&P 500, and did not waive eligibility rules that would have also delayed or prevented similar expedited access for AI firms OpenAI and Anthropic despite their expected IPOs; the decision keeps requirements such as seasoning period and minimum investable weight, meaning potential passive-fund buying triggered by S&P 500 inclusion will occur only after the standard criteria are met.
