S&P Global said it will not change its eligibility rules, effectively denying SpaceX an early entry into the S&P 500 index [1].
This decision prevents the aerospace company from gaining immediate inclusion in one of the world's most influential stock market benchmarks. Such an entry typically triggers massive buying from passive index funds, which can significantly inflate a company's valuation during its initial public offering.
S&P Dow Jones Indices, the manager of the S&P 500, said on June 4, 2024, that it would keep its current eligibility requirements unchanged [1, 2]. The company is not loosening the rules to allow for fast-track inclusion for new listings [3, 4].
SpaceX, founded by Elon Musk, has a planned IPO date of June 12, 2026 [5]. The company has already begun its investor roadshow as it prepares to move from a private entity to a publicly traded corporation.
By maintaining the existing rules, S&P Global ensures that all companies must meet the same stringent financial and liquidity criteria before joining the index. This includes requirements regarding a company's history of positive earnings, and the availability of shares for public trading.
The refusal to create a special carve-out for mega-IPOs means SpaceX will have to wait until it meets the standard requirements after its listing is complete. This puts the company in the same position as other large firms that have transitioned to the public market in recent years.
“S&P Global said it would not change its eligibility rules”
The decision by S&P Global reinforces the stability and predictability of the S&P 500 by resisting pressure to modify rules for high-profile companies. For SpaceX, the lack of immediate index inclusion means the stock will not benefit from the automatic, large-scale buying pressure that usually accompanies S&P 500 membership, placing more emphasis on organic investor demand during the June 12, 2026, IPO.
