SpaceX IPO Poised to Reshape Markets and Index Rules
SpaceX’s forthcoming IPO, potentially valuing the company at up to $2 trillion, is already reshaping market dynamics by boosting demand for mega-cap tech and prompting the S&P 500 to consider fast-tracking SpaceX’s index inclusion; Nasdaq has already moved to fast-track SpaceX onto the Nasdaq 100, while AI IPOs from OpenAI and Anthropic are expected later this year. Proposed S&P 500 rule changes for MegaCaps—no profitability requirement, a six-month inclusion window instead of 12, and removal of the 10% public float requirement (SpaceX’s float is about 5%)—could take effect around June 8 if approved by May 28. Critics argue the changes favor issuers, while supporters say indices should reflect current market realities.
