On June 12, 2026, SpaceX lists on Nasdaq under the ticker SPCX. The day before, the group priced its IPO at 135 USD per share and raised 75 billion USD, the largest IPO in history.

Market value exceeds 2 trillion USD on day one. - The bell is rung simultaneously at Nasdaq MarketSite in Times Square and at the Starbase site in Texas. - According to the prospectus cited by NPR, proceeds will fund launchers and Starlink, and accelerate the pivot to AI: terrestrial data centers, AI chips and "orbital AI compute infrastructure." ### Key figures | Metric | Value | |---|---| | Amount raised | 75 billion USD | | IPO price | 135 USD | | Implied valuation | about 1.77 trillion USD | | First-day close | 160.95 USD (+19%) | | Q1 2026 net loss | 4.3 billion USD | | Elon Musk's voting power | about 85% | ### Caveats SpaceX is not profitable. Morningstar values the group at just 780 billion USD and rates uncertainty "very high," citing execution, the AI infrastructure buildout and dependence on Elon Musk, who controls the board. ### Why it is a turning point For the first time, a frontier AI lab becomes publicly tradable, backed by a space group. The deal paves the way for the expected IPOs of OpenAI and Anthropic. ### Key takeaways SpaceX's record makes AI a central driver of an industrial group's valuation. Governance, concentrated in Elon Musk's hands, remains the main point of attention.
