SpaceX Soars 19% to $161.11 on Debut, Becomes U.S. Sixth-Largest by Market Cap; Russell 1000 May Add Within 5 Days, S&P 500 Access Blocked

According to Investopedia, SpaceX listed on June 13, opening at $150 per share and closing at $161.11, up 19.34% from its $135 IPO price. The company's market capitalization surged to $2.1 trillion, ranking it the sixth-largest publicly traded U.S. company by market value.

While the S&P Dow Jones Index Company maintained its current inclusion rules—requiring profitability, 12 months of trading history, and minimum free-float criteria—SpaceX is expected to enter other major indexes rapidly. FTSE Russell's Russell 1000 could add SpaceX within five trading days under current rules, and Nasdaq modified standards to allow qualifying mega-IPOs into the Nasdaq-100 Index within 15 trading days. Broad market indexes including the S&P U.S. Total Market Index and CRSP U.S. Stock Market Index may also include SpaceX shortly after listing, potentially triggering passive fund buying across multiple benchmarks.
