Mr. Musk’s rocket and satellite maker disclosed its financial performance as it prepares to go public in what is set to be one of the largest offerings to date.
SpaceX, Elon Musk’s privately held rocket and satellite maker, has long been something of a financial mystery, even as it became synonymous with audacious plans to reach the stars.
That changed on Wednesday, when the company revealed just how lucrative its rocket launch and satellite internet businesses have been.
SpaceX’s revenue soared to $18.7 billion in 2025, up 33 percent from a year earlier, the company disclosed in a filing required of firms that are seeking to go public. In the first three months of this year, revenue rose to $4.7 billion from $4.1 billion in the same period a year ago.
But the company lost more than $4.9 billion last year, compared with a $791 million profit in 2024, as capital expenditures nearly doubled to $20.7 billion from heavy spending on artificial intelligence development. In the first three months of this year, SpaceX lost almost as much money as all of 2025, recording a $4.3 billion loss.
SpaceX, which also owns the social media platform X and xAI, the maker of the Grok chatbot, drew back the curtain on its finances for the first time as it prepares for what could be one of the largest initial public offerings to date. The company, which values itself at $1.25 trillion, is aiming to reach the stock market as early as next month and could try to raise $50 billion to $75 billion from the offering.
If successful, SpaceX’s I.P.O. could pave the way for other enormous offerings, including from the A.I. companies Anthropic and OpenAI, which is also preparing to file confidentially for an I.P.O. in the coming weeks. Last week, Cerebras, an A.I. chip maker, kicked off the expected wave of offerings and rose 68 percent on its first day of trading, becoming the largest public offering so far this year and the biggest of any technology firm since 2019.
