S&P’s decision could also delay index inclusion for companies like SpaceX and Anthropic|Daniel Oberhaus|CC BY-SA 4.0

S&P Global declined to change its index entry requirements, dimming SpaceX’s chances of a quick inclusion in the S&P 500 after its anticipated blockbuster IPO.

The decision comes as Elon Musk’s company is expected to list on June 12 and could become the largest IPO in history, with a valuation of approximately $1.75 trillion.

To be included in the S&P 500 index, companies must be profitable under Generally Accepted Accounting Principles (GAAP) in their most recent quarter and over the trailing 4 quarters.

That could pose a challenge for SpaceX, which reported a net loss of $4.94 billion in 2025 despite a 33% increase in revenue to $18.67 billion.

Nasdaq has eased eligibility requirements, paving the way for newly listed megacaps to join the Nasdaq-100 more quickly.

S&P’s decision could also delay index inclusion for other companies, such as Anthropic, that are expected to pursue blockbuster IPOs.
