Elon Musk spent twenty-five years making rockets reusable and turning orbit into a commercial address. Now his company is telling Wall Street the real money lies in selling artificial intelligence to corporations -- a pitch buried inside a 300-page S-1 regulatory document.

Key Takeaways:

SpaceX is preparing a summer IPO aimed at a $1.75 trillion valuation and roughly $75 billion raised, which would top every public listing ever recorded.
The filing claims a total addressable market of $28.5 trillion, with $22.7 trillion coming specifically from enterprise AI -- a category currently led by Anthropic and OpenAI.
The xAI unit SpaceX absorbed in February posted a $6.4 billion operating loss in 2025 and swallowed $12.7 billion of capital expenditure, more than rockets and satellites combined.

The S-1 filing sets out what a company expects to earn, what risks it faces, and how big the prize really is. SpaceX answered that last question with a number few companies would dare print. More than ninety percent of its claimed opportunity -- about $26.5 trillion -- sits in AI. The lion's share of that, $22.7 trillion, comes from selling AI services to businesses.

"We believe we have identified the largest actionable total addressable market in human history," the filing says.

Total addressable market figures are neither forecasts nor valuations. They are ceilings -- the theoretical maximum revenue a firm could collect if it somehow served every possible customer. Investors treat them as signals of ambition rather than arithmetic. Uber claimed $5.7 trillion for ride-sharing alone when it went public in 2019, so huge numbers are not new. SpaceX just printed one nearly five times bigger.

What makes the number jarring is the gap between the pitch and the present. SpaceX today earns its keep from Starlink and launch contracts, not chatbots. Starlink, the satellite internet arm, pulled in $11.4 billion of the group's $18.7 billion revenue last year and produced $4.4 billion in operating profit. Everything else on the income statement pointed downward.

The company did not respond to a request for comment.

The xAI problem

In February, SpaceX absorbed xAI, the research outfit Musk founded in early 2023. On paper, the acquisition gave the group a credible AI arm. In the filing, it looks closer to a hungry passenger.

The AI unit lost $6.4 billion in operating terms last year, four times the $1.6 billion it lost in 2024. Those losses wiped out Starlink's profit and then some. Overall, SpaceX ended 2025 down $4.9 billion.

The spending story is sharper. Group capital expenditure climbed to $20.7 billion in 2025. AI took $12.7 billion of that -- more than the rocket and connectivity businesses combined. The filing warns prospective investors that the outflow is not slowing, and that SpaceX plans to manufacture graphics processing units, the chips that run AI models, in-house.

To turn the spending into revenue, the company says it will deploy a specialist sales force and send engineers known as "forward deployed engineers" to live inside client operations and help staff actually use the tools. It also plans to commercialize products inherited from xAI, including Grok Enterprise and Macrohard, an agentic platform developed jointly with Tesla.

"We believe that our enterprise strategy, which is focused on serving the digital needs of the world's largest industries with Al solutions, positions us competitively to pursue this rapidly growing opportunity," the filing says.

A market with entrenched incumbents

Enterprise AI is not empty territory. Anthropic and OpenAI dominate the category today and have each signaled plans to go public, potentially as early as this year. SpaceX will arrive at the party carrying rocket fuel, a loss-making research lab, and an unusually large chequebook.

One source familiar with the company's finances was blunt about the valuation gap between what can be measured and what the IPO will likely price in.

"If you decide I'm going to be really sober about this and only value the businesses that I can actually see, you're not going to be in the ballpark of what the market will almost certainly set the valuation to be," the source said.

Translated: public markets are going to pay for the promise, not the P&L. A $1.75 trillion price tag on a group losing billions depends on investors buying the $22.7 trillion enterprise-AI story. If they do, it will be the biggest IPO ever written. If they squint at the Starlink figures and nothing else, the arithmetic falls apart.

Musk has wanted a central seat at the AI table for years. The filing is the most concrete statement yet of what that ambition costs -- and what it would pay back if the largest addressable market in human history turns out to be addressable at all.
