TL;DR
The S&P 500 has officially rejected applications from SpaceX, OpenAI, and Anthropic for inclusion, citing strict eligibility rules. This decision affects billions in passive fund investments and raises questions about future AI and tech company entries.
The S&P Dow Jones Indices announced on June 6, 2026, that it will not include SpaceX, OpenAI, or Anthropic in the S&P 500 index, citing adherence to existing eligibility criteria. This decision prevents these companies from triggering large passive investment flows and impacts their market prospects.
The decision follows discussions around rule changes that could have allowed SpaceX to gain entry based on its IPO plans and financial status. Despite proposals to modify investable weight factors for certain indexes, the S&P 500 maintained its strict criteria, including financial viability and seasoning periods. SpaceX’s current unprofitability, with a debt load reaching $29 billion, and the uncertain profitability of AI firms like OpenAI and Anthropic, contributed to the rejection. The move comes days after analysts labeled SpaceX as overvalued, with a valuation of $780 billion, less than half its IPO target of $1.75 trillion. While other indexes like Nasdaq and FTSE Russell have approved faster entry for SpaceX and similar firms, the S&P 500’s decision underscores its conservative approach.
Why It Matters
This decision is significant because it blocks a potential $14 billion passive investment inflow for SpaceX and billions more for AI firms, which could have influenced market valuations and liquidity. The rejection highlights the challenges tech and AI companies face in meeting the S&P 500’s strict eligibility criteria, especially regarding profitability and financial stability. For investors, it underscores the importance of index rules in shaping market dynamics and the valuation landscape for large-cap tech and AI firms.

Background
The S&P 500’s eligibility rules have historically emphasized financial stability and profitability, which many tech startups and AI companies struggle to meet at early stages. Recent proposals aimed to relax some criteria, such as adjusting investable weight factors, but these were not adopted. Meanwhile, other indexes like Nasdaq-100 and FTSE Russell have adopted accelerated entry rules for certain high-profile companies, contrasting with the S&P 500’s conservative stance. The decision comes amid ongoing debates about overvaluation in the tech sector, with SpaceX’s valuation being notably reduced from earlier estimates, and concerns about the sustainability of AI firms’ growth models.
