SpaceX, Elon Musk’s rocket and satellite maker, officially finalized its initial public offering as the world’s largest stock market debut, in a testament to the tech mogul’s influence and people’s belief in his business vision.
On Thursday, SpaceX confirmed its I.P.O. price was set at $135 a share and that it would sell more than 555 million shares, the company said in a statement. That means SpaceX would raise around $75 billion from its offering, putting its valuation at $1.77 trillion.
With those numbers, SpaceX would shatter an I.P.O. record previously set by Saudi Aramco. Saudi Arabia’s state-owned oil company was valued at $1.7 trillion and raised more than $29 billion when it went public in 2019. SpaceX will begin trading publicly on Friday under the ticker symbol SPCX.
A SpaceX spokesman did not immediately respond to a request for comment.
SpaceX’s long journey to the stock market has been defined by many superlatives. Apart from being the biggest-ever I.P.O., SpaceX is also the most dominant space company from the world’s richest man. And it would become the benchmark for a wave of other offerings, which are all expected to unleash an avalanche of wealth across Silicon Valley and Wall Street, creating influential new titans in the process.
Anthropic, the artificial intelligence start-up that makes the Claude chatbot, and its ChatGPT-making rival, OpenAI, have both confidentially filed to go public in recent days. Each company has a valuation approaching $1 trillion. If Anthropic and OpenAI successfully pull off public offerings, it would mean another milestone: Three-trillion-dollar companies reaching the stock market for the first time.
A defining trait of the offerings is that they are likely to make those who are already wealthy even wealthier. At $135 a share, the SpaceX stake controlled by Mr. Musk would be worth more than $860 billion. (He cannot sell some of the SpaceX shares he controls until the company hits various operational milestones, according to the firm’s filings.)
And a slight increase in the company’s share price in its first days of trading could turn Mr. Musk, 54, into the world’s first trillionaire.
Mr. Musk, who founded SpaceX in 2002, has redefined the space industry with partly reusable rockets and a satellite internet service, Starlink. In February, SpaceX bought his A.I. company, xAI, which owned his social media platform, X. He separately runs the electric carmaker Tesla, as well as other companies.
SpaceX, which has contracts with NASA and other federal agencies, had long been something of a financial mystery. Last month, the company revealed a full picture of its finances for the first time in an I.P.O. prospectus. The company reported that it had lost more than $4.9 billion last year, compared with a $791 million profit in 2024, because of increased expenditures on A.I. Revenue was $18.7 billion last year, up 33 percent from the previous year.
SpaceX’s underwriters, which include Goldman Sachs and Morgan Stanley, also have the option of purchasing an additional 83 million I.P.O. shares from the company to sell to investors. If the underwriters exercise that option, the company would raise more than $86 billion in the offering.
