SpaceX IPO: Key Records and Milestones Behind the Company’s Market Debut

Mumbai | June 17, 2026 

SpaceX has broken a string of Wall Street records within days of its stock market debut. The aerospace, satellite and AI company raised $75 billion in its initial public offering, the largest IPO in history, eclipsing the previous global record held by Saudi Aramco’s 2019 listing by more than double. 

A Record Public Listing 

Shares were priced at $135 each, valuing SpaceX at approximately $1.77 trillion ahead of trading, instantly making it one of the most valuable companies in the world before a single share changed hands publicly. The stock closed its first session 19% higher at $160.95, taking the market capitalisation above $2.1 trillion, one of the fastest moves to that threshold by any company on record. Within days, the stock had climbed more than 60% above its IPO price, touching levels around $220. 

Trading and Options Records 

Three trading sessions after listing, SpaceX’s market value reached approximately $2.7 to $2.8 trillion, overtaking Amazon and briefly passing Microsoft to rank among the world’s five most valuable companies. More than 510 million shares worth roughly $84 billion changed hands on the first day. SpaceX options contracts traded approximately 1.8 million times on debut day, surpassing the previous record of about 364,000 contracts set by Meta Platforms in 2012, with total premiums traded estimated at around $2.8 billion. The company became the third most actively traded single stock options name in the US, behind Tesla and Nvidia. 

Investor Demand and Wider Impact 

Retail investors received roughly 20% of IPO allocations, a higher share than most large US offerings, with demand reportedly exceeding available shares multiple times over. The listing pushed Elon Musk’s net worth above $1 trillion, making him the first person to cross that threshold. It has also reset expectations for the next wave of mega listings, including potential offerings from AI companies such as Anthropic and OpenAI. 

SpaceX Business Segments and Strategic Significance 

SpaceX runs three launch vehicles, the medium-lift Falcon 9, the heavy-lift Falcon Heavy, and the in-development Starship, the largest rocket ever flown. It also operates Dragon spacecraft for NASA’s crew and cargo missions to the International Space Station, and Starlink, its satellite internet network, now the company’s largest revenue source. 

In February 2026, SpaceX acquired xAI, Elon Musk’s artificial intelligence company, as a wholly owned subsidiary in an all-stock deal, aiming to combine its rocket and satellite capabilities with AI technology to build space-based data centres. The following month it announced Terafab, a chip manufacturing project with Tesla and xAI built around AI compute capacity. The New York Times also reported, though SpaceX has not separately confirmed it, that the company had agreed to acquire AI coding startup Cursor for $60 billion. Together, these moves have positioned SpaceX as a combined space, satellite and AI infrastructure business heading into its listing, aligning with the broader investor appetite for AI-linked offerings. 

Outlook 

Whether the valuation holds remains to be tested, but as a stock market debut, SpaceX’s listing already ranks among the most significant in financial history.
