SpaceX became the sixth-largest company by market cap after its $1.8 trillion IPO valuation jumped in early trading.
SpaceX’s market valuation climbed to $2.4 trillion on June 19, 2026, following its June 12 IPO, which priced the company at $1.8 trillion. The surge makes it the sixth-largest company globally by market capitalization, reflecting strong investor demand for its satellite internet, launch services, and AI ventures.
The company’s Starlink unit leads the satellite internet sector, while its Falcon 9 rockets dominate commercial launches. SpaceX’s Starship program and xAI division, which developed the Grok AI model, contribute to an estimated $28.5 trillion total addressable market. Competitors Anthropic and OpenAI also filed for IPOs in May and June, but SpaceX’s scale sets it apart.
Early trading activity suggests robust appetite for aerospace and AI-linked equities, though long-term performance remains tied to execution in high-growth segments.
