S&P 500 Rejects SpaceX, Also Blocking OpenAI and Anthropic

S&P Dow Jones Indices decided not to modify the company-inclusion rules for major indices such as the S&P 500, effectively rejecting the possibility of "fast-tracking" ultra-large newly listed companies like SpaceX into the index. The current rules require newly listed companies to go through a 12-month observation period after listing and to meet conditions on profitability and public float; S&P stated that it will not relax these standards merely because a company has a very large market capitalization. This decision has the most direct impact on SpaceX, because if it conducts its highly anticipated IPO, the market had originally hoped it could be included in the S&P 500 more quickly, thereby attracting buying from ETFs and passive funds that track the index. According to estimates from Bloomberg Intelligence, if fast-tracked inclusion had happened, SpaceX could have brought in around $14 billion in passive buying, OpenAI possibly over $8 billion, and Anthropic about $4.6 billion. Now that the rules remain unchanged, it means these capital inflows will at least be delayed, and it also reduces the likelihood that retirement accounts and ETF investors would be forced to immediately absorb highly valued companies that may not yet have stable profits. For the AI industry, this is not product or model technology news, but an important signal from the capital markets about the IPO path of AI giants: even with extremely high valuations, OpenAI and Anthropic cannot rely on scale alone to obtain a fast-track ticket into the S&P 500 if they go public in the future. Supporters of fast-tracked inclusion argue that ultra-large companies are sufficiently representative of the market even right after listing; opponents worry that if the index makes exceptions for a few highly valued, not-necessarily-profitable companies, it would transfer more risk onto passive investors. By choosing to maintain the traditional threshold this time, S&P shows that it places greater value on rule consistency and index quality, rather than catering to the latest wave of AI and space-tech giants' IPO fever.
