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

S&P Dow Jones Indices rejected SpaceX's request for accelerated entry into the S&P 500 index on June 4, closing the door on a potential rule change that would have also allowed AI companies OpenAI and Anthropic to join major indexes soon after their own IPOs. The decision blocks SpaceX from accessing billions of dollars in passive investment funds and maintains existing requirements for profitability, a 12-month seasoning period, and minimum public float. The ruling provides relief to investors concerned about retirement savings exposure to SpaceX's unprofitable AI bets and $29 billion debt load.

SpaceX has requested unusually swift entry into several leading stock market indexes as a condition of its historic stock market debut. But the S&P 500 stock market index representing many of the largest profitable US companies has surprised market analysts by refusing to bend the rules for Elon Musk’s space and AI company.

The June 4 decision by S&P Dow Jones Indices—the company that creates and manages stock market indexes such as the S&P 500—means that SpaceX will not gain accelerated access to potentially billions more dollars through passive investment funds that automatically purchase shares of S&P 500 companies. An exception for SpaceX could have also allowed leading AI companies such as OpenAI and Anthropic to gain entry not long after their own expected initial public offerings (IPOs). That possibility has now been shuttered.

The news will likely come as a relief to people concerned about passive investor money and people’s retirement savings plans having greater exposure to the market risks associated with SpaceX’s big bet on AI and speculative orbital data center plans. AI companies are generally facing more challenges in funding and building expensive AI data centers, even as they shift more of the subsidized costs of running AI services onto shocked customers through usage-based pricing.

To weigh expedited entry for SpaceX, the S&P Dow Jones Indices held a monthlong consultation to consider changing or waiving several main requirements for so-called MegaCap companies with “unprecedented market capitalizations.”

Those proposed changes included shortening the “seasoning period” for new IPOs from 12 months to six months, waiving the investable weight factor (IWF) requirement for MegaCap companies to make at least 10 percent of their shares publicly available, and waiving the requirements for MegaCap companies to demonstrate profitability in the latest quarter of the financial year along with the previous four quarters.

Such rule changes would have accommodated SpaceX’s plan to only offer approximately 3 percent of its IPO shares to public investors, and the fact that SpaceX is currently unprofitable with a growing debt load that has reached $29 billion because of its spending spree on AI infrastructure.
