SpaceX made history with the biggest-ever IPO, sending it into the top ranks of the largest public companies and putting founder Elon Musk on the verge of becoming the world’s first trillionaire.
The company raised $75 billion in the IPO, pricing 555.6 million shares at $135 each, according to a statement on its website Thursday. SpaceX’s IPO is more than double the size of Saudi Aramco’s $29.4 billion listing in 2019.
Space Exploration Technologies Corp., as it is officially known, has given the underwriting banks an over-allotment option to buy an additional 83.3 million shares at the IPO price, the statement shows, which would increase the size of the deal to about $86 billion if fully exercised.
The IPO drew demand for more than four times the available shares, Bloomberg News reported.
At the IPO price, SpaceX has a market value of $1.77 trillion. Accounting for employee stock options and restricted share units, the pricing gives it a fully diluted valuation of about $1.8 trillion. The company will debut on Nasdaq and Nasdaq Texas Friday under the symbol SPCX.
Musk’s first-mover advantage allows SpaceX to notch another jump in its valuation in less than a year. SpaceX’s acquisition of Musk’s xAI in February vaulted the combined company’s private valuation to $1.25 trillion, and the original SpaceX value to $1 trillion. That was up from about $800 billion in an insider share sale in December — roughly double its mark from July 2025.
At the IPO price of $135, SpaceX’s market value ranks it among the top 10 public companies globally, and make it larger even than Musk’s own Tesla Inc.
Musk’s Paper Gains
Musk’s net worth will jump roughly $275 billion to about $970 billion after taking into account SpaceX’s offering price, just shy of trillionaire status, according to calculations by the Bloomberg Billionaires Index. Musk’s SpaceX stake, including options, is worth $688 billion at $135 a share.
A successful showing in public markets Friday could tip the scales into making him a trillionaire. His wealth will boom even further if he meets performance-based conditions for awards of as many as 1.3 billion additional class B shares in aggregate, split into tranches.
