Summary
SpaceX executed Wall Street's largest initial public offering in history on June 12, 2026, with shares soaring 19% on their debut day. The offering raised $75 billion and valued SpaceX at $2.1 trillion following its first-day close just below $161 per share, after the stock opened at $150 and briefly reached $168 intraday. This performance substantially exceeded the historical average of 7% first-day appreciation observed across IPOs from 1980 through 2025, according to Jay Ritter, professor at the University of Florida's Warrington College of Business.
The IPO elevated SpaceX to the sixth largest U.S. public company by market capitalization, surpassing Musk's electric vehicle manufacturer Tesla. Between his SpaceX holdings and Tesla equity, Musk's net worth reached approximately $1.1 trillion, according to Forbes, establishing him as the world's first trillionaire. His 42% ownership stake in SpaceX ensures unilateral control over the company's strategic and capital allocation decisions.
Musk justified the IPO as necessary funding for SpaceX's long-term capital requirements in satellite deployment, orbital data center construction, and artificial intelligence infrastructure development. The company's prospective objectives include establishing human colonies on Mars and expanding lunar transportation capabilities. Speaking from SpaceX's Starbase facility in South Texas during the Nasdaq bell-ringing ceremony, Musk reiterated the company's ambition "to make life multiplanetary" and stated SpaceX's intent to transport individuals to the Moon, Mars, and beyond. Despite current operating losses, investor appetite reflects confidence in these ambitious technological and commercial programs materializing into profitability.
The strong reception underscores market willingness to value speculative growth trajectories and transformative technological bets at substantial multiples. SpaceX's transition to public markets positions it to access capital markets for continued expansion while maintaining Musk's operational control through his controlling stake.
