TL;DR
The S&P 500 has refused to include SpaceX, OpenAI, and Anthropic, citing their financial viability and eligibility rules. This decision affects billions in passive investment flows and raises questions about future index entries.
The S&P 500 has officially rejected SpaceX, OpenAI, and Anthropic from inclusion in its index, citing adherence to its strict eligibility criteria, including financial viability standards. This decision impacts billions of dollars in passive investment flows and has implications for the companies’ valuations and IPO strategies.
The S&P Dow Jones Indices confirmed that no changes will be made to the eligibility criteria, including rules on financial viability, seasoning periods, or minimum IWF thresholds. Despite proposals that would have accelerated SpaceX’s entry due to its IPO and potential passive fund inflows—estimated at over $14 billion for SpaceX, $8 billion for OpenAI, and $4.6 billion for Anthropic—the index provider maintained its standards. The decision comes days after analysts from Morningstar described SpaceX as overvalued, with a valuation of $780 billion, less than half of its IPO target of $1.75 trillion. Meanwhile, other indices like Nasdaq and FTSE Russell have granted accelerated entry to SpaceX and other companies, but the S&P 500 remains firm on its criteria.
According to the S&P Dow Jones Indices, the core reason for the rejection is that SpaceX, OpenAI, and Anthropic do not meet the profitability and stability requirements necessary for inclusion. The index provider also clarified that a recent rule change, which allowed faster entry for some indexes, does not apply to the S&P 500. This decision affects the companies’ ability to benefit from passive investing, which follows the index and accounts for trillions in assets managed by firms such as Vanguard and Fidelity.
Why It Matters
This decision matters because inclusion in the S&P 500 triggers massive passive investment flows, totaling around $7.5 trillion in assets. Such inflows can significantly boost a company’s market capitalization and investor visibility. The rejection underscores the index provider’s focus on financial stability over potential growth or strategic importance, which could influence how tech and AI firms approach IPO and index eligibility in the future. For investors, this raises questions about the valuation and growth prospects of these companies, especially as some are seen as overvalued or unprofitable.

Background
The S&P 500’s criteria for inclusion have historically emphasized profitability, liquidity, and market capitalization. Recently, there has been debate over whether these standards should be relaxed for mega-cap companies, especially those in emerging sectors like AI and space technology. SpaceX’s IPO, valued at $1.75 trillion, was expected to bring significant passive inflows, but the company’s current unprofitability and high debt load—reaching $29 billion—disqualified it under existing rules. OpenAI and Anthropic, as private AI firms, also do not meet the profitability thresholds, despite their high-profile status and potential for future growth.
Other indexes, such as Nasdaq-100 and FTSE Russell, have moved to accelerate entry for SpaceX and similar companies, but the S&P 500 remains committed to its standards. This divergence highlights ongoing debates about index rules and the valuation of innovative tech firms amid concerns over overvaluation and financial stability.
