SpaceX completed its initial public offering on June 12, 2026, listing on the Nasdaq under the ticker SPCX at $135 per share and raising $75 billion in the largest IPO in history, surpassing Saudi Aramco's $29.4 billion in 2019. On its first trading day, shares opened at $150, reached an intraday high of $176.52, and closed at $160.95, a 19 percent gain from the offer price.
The first-day closing price gave SpaceX a market capitalization of approximately $2.1 trillion, according to CNBC and other outlets, with an intraday peak valuation near $2.3 trillion when shares hit $176.52. The valuation briefly exceeded that of Meta Platforms and Samsung before settling, trailing only Nvidia at roughly $5 trillion.
The IPO also made Elon Musk the world's first trillionaire, NBC News reported from the Nasdaq floor, as the stock surge pushed his net worth past the trillion-dollar threshold.
SpaceX's record debut sets the benchmark for the highest IPO market cap in 2026, but potential challengers remain. Anthropic, an AI company previously reported to be targeting a confidential S-1 filing and an October listing, and xAI could still go public later this year at valuations that might surpass SpaceX's roughly $2.1 trillion first-day close. As of August 2026, no subsequent IPO has matched SpaceX's first-day market cap, and the field of potential contenders remains uncertain with months left in the year.
