SpaceX

Founded by Elon Musk in 2002 and headquartered in Hawthorne, California, SpaceX is the dominant commercial launch provider, flying the reusable Falcon 9 and Falcon Heavy and developing the fully reusable Starship super-heavy system from Starbase, Texas. The company also operates Starlink, a low-Earth-orbit broadband constellation of thousands of satellites that surpassed 10 million active customers by early 2026. After a December 2025 insider share sale valued it at roughly $800B, SpaceX went public on June 12, 2026 in a record ~$75B IPO (Nasdaq: SPCX), debuting at a market capitalization of roughly $2.1 trillion — the largest IPO in history.
