SpaceX Reveals $18.7bn Revenue and $4.9bn Loss Ahead of Record-Breaking IPO

For more than two decades, SpaceX has been Silicon Valley’s most closely guarded balance sheet, a privately held empire of reusable rockets and orbiting broadband terminals whose numbers were the subject of feverish speculation but never confirmation.

On Wednesday, Elon Musk’s space and satellite group finally pulled back the curtain, and the figures suggest a company spending astronomical sums to chase an even bigger prize.

In a prospectus filed in preparation for a stock market debut that could rank as the largest in history, SpaceX disclosed revenue of $18.7bn (£14.7bn) for 2025, a 33 per cent leap on the previous year. But the headline numbers also laid bare the cost of Mr Musk’s ambitions. The Hawthorne-based group swung to a loss of more than $4.9bn, against a $791m profit in 2024, as capital expenditure nearly doubled to $20.7bn from $11.2bn the year before. Much of the increase, the company said, was funnelled into artificial intelligence development, satellite manufacturing and the build-out of its Starship programme.

The disclosure, lodged with the Securities and Exchange Commission, marks the first time the world’s most valuable private business has been forced to show its working. According to filings reviewed by CNBC, SpaceX is valuing itself at $1.25 trillion and could float as soon as next month, aiming to raise between $50bn and $75bn — a sum that would dwarf Saudi Aramco’s $29bn record listing in 2019.

For City watchers, the prospectus reads as a study in the trade-offs of frontier capitalism: vertiginous top-line growth bankrolled by equally vertiginous cash burn. Starlink, the satellite broadband arm that now serves several million subscribers worldwide and is fast becoming a fixture in rural Britain, drove the bulk of the revenue expansion. Launch services, including National Aeronautics and Space Administration and Pentagon contracts, contributed the rest. But the cost of staying ahead of rivals such as Jeff Bezos’s Project Kuiper has rarely been steeper. As we reported in October, bankers have been quietly pencilling in a valuation as high as $1.75tn once retail investors are factored in.

The group’s reach now extends well beyond rocketry. Following the acquisition earlier this year of xAI, the artificial intelligence venture behind the Grok chatbot, and the social media platform X, SpaceX has become something approaching a conglomerate of Mr Musk’s pet projects — a structure unpicked in our earlier analysis of the xAI deal. The integration costs of that combination help explain the swing into the red, but they also underline the strategic bet at the heart of the float: that rockets, satellites and large language models are converging into a single, vertically integrated infrastructure play.

A successful debut would all but guarantee that Mr Musk, already the world’s richest person, crosses the threshold to become its first trillionaire. It would also enrich a swathe of Wall Street institutions and long-serving employees whose paper fortunes have been locked up for the better part of a decade.

The flotation, if it lands as planned, looks set to unblock a pipeline of mega-listings that has been jammed since the 2021 boom went bust. Cerebras, the Californian artificial intelligence chip designer, kicked off what bankers are billing as a generational window last week, closing 68 per cent above its issue price on its Nasdaq debut and ranking as the biggest technology offering since Uber went public in 2019. Anthropic is understood to be sounding out advisers, while OpenAI, the maker of ChatGPT, is preparing to file confidentially in the coming weeks.

For all the excitement, the prospectus also signals the risks that come with putting a company of this profile into public hands. SpaceX’s fortunes are tied unusually tightly to a single founder, whose attention has been split across half a dozen ventures and whose political pronouncements have at times unsettled customers and regulators alike. Capital expenditure of $20bn-plus a year is not easily trimmed when Starship development and Starlink’s next-generation constellation depend on it. And the firm’s profit reversal will give pause to fund managers weighing a multi-billion-dollar punt on a stock with limited room for valuation expansion.

Mr Musk and a SpaceX spokesman did not respond to requests for comment. Whether public-market investors share the company’s view of its own worth will be settled in a matter of weeks. What is no longer in any doubt is the scale of the numbers, and the audacity of the bet.
