SpaceX IPO Surges 19% as Markets Absorb Exclusion from S&P 500

SpaceX began trading Friday after its blockbuster June 12 IPO and rose 19.22% without disrupting equities. The S&P 500 finished the week up 0.5%, the Dow gained 0.8%, and the Nasdaq added 0.3%. S&P had already ruled out fast-track inclusion, citing its standard one-year seasoning, profitability, and 10% float requirements that SpaceX fails to meet. Other providers moved to ease rules, shifting immediate flows to non-S&P indexes and upcoming rebalances on June 18, June 26, and July 6. Attention now turns to whether investor appetite for mega-cap tech IPOs will hold for candidates such as Anthropic and OpenAI.
