The SpaceX AI Business Just Made the Rockets Irrelevant

SpaceX reported third-quarter results on Tuesday, and the numbers no longer describe a rocket company. The SpaceX AI business drove most of the beat. Revenue reached fourteen point five eight billion dollars, up one hundred sixty-one percent from a year earlier and well above the twelve point seven billion analysts had expected, according to S&P Global Market Intelligence consensus figures cited by Fortune. Net income landed at four point four billion dollars, or thirty-five cents a share, reversing a five point five billion dollar loss the year before, the Guardian reported. It was only the company's second earnings report since going public in June at one hundred thirty-five dollars a share, and Zot News collected the headline figures.

The size of the beat matters less than where the money came from. The SpaceX AI business, newly renamed Super Intelligence, generated seven point five six billion dollars in the quarter, nearly triple the two point five six billion it produced in the spring and ahead of the six point three billion analysts projected. That is more than the connectivity business, which includes Starlink, and the rocket business made combined, at about seven billion dollars between them. Rockets, the thing the company is named for, now account for roughly twelve percent of revenue. SpaceCAPEX published the full segment breakdown. The name is already taken, incidentally: the White House tried to claim "super intelligence" for all of AI last month, as this column noted at the time.

The SpaceX AI business is mostly a landlord operation. Customers leasing computing capacity from it include Anthropic, Google, and Reflection AI, and the division folds in Grok plus the newly acquired Cursor, which contributed six hundred eight million dollars from its consolidation date, according to AInvest. The division swung into operating profit in the quarter. On the earnings call, chief executive Elon Musk said chips are no longer the main constraint on expanding AI capacity. Power and cooling are, Business Insider reported. Musk added that the company has struggled to find available hardware, naming Nvidia's GB300 and GB200 systems, Google TPUs, Amazon Trainium chips, and Nvidia H100 GPUs, and said the compute shortage could persist for years, KuCoin reported.

Rockets are now the side business

The reframe is stark. SpaceX spent two decades making rockets reusable, and Starlink was supposed to be the cash machine that paid for Mars. Instead the cash machine turned out to be renting out processors. Starlink had a soft quarter, adding one point six million consumer subscribers and missing analyst forecasts, even as enterprise and government revenue climbed. The rocket division grew six percent. The SpaceX AI business grew eight hundred thirty percent. The same pattern showed up earlier this month, when this column argued that SpaceX's spectrum ambitions reveal a company that wants to own the pipes, not just fly through them. The future of the company is humming in a warehouse, not going up.

The bottleneck moved to the power grid

On the earnings call, Musk said the constraint on AI growth is no longer chips. It is electricity and the equipment that keeps servers cool. Short-term computing contracts are renewing at higher prices, and Musk said the company could rent out its capacity several times over if it accepted every request. That turns every data center fight into an energy fight. Gen Z activists in Virginia are already pushing for a moratorium on new data centers, as GenZNewZ reported earlier this month. The AI race spent years being described as a silicon shortage. The new description, straight from the earnings call, is a power shortage, and the SpaceX AI business is now a utility-scale power customer that happens to own rockets.

The bill is the story now

There is a catch, and it is enormous. SpaceX spent nineteen point six billion dollars on capital expenditures in the quarter, sixteen point four billion of it on AI infrastructure. Finance chief Bret Johnsen told analysts that spending could double this quarter to between thirty-five and forty billion dollars, while new computing deployments are paying for themselves in under a year. The under-a-year payback claim is doing a lot of work here. If returns stay ahead of the spending, the SpaceX AI business justifies the outlay. If they do not, it is the most expensive landlord operation ever assembled. Either way, the argument is no longer whether AI demand exists. Musk said the company could rent its capacity several times over. Demand is the one thing nobody on the call questioned.

The Mars posters can stay on the wall. But the company that was supposed to make humanity multiplanetary now makes most of its money the way a cloud provider does, and its chief executive spends earnings calls talking about electricity instead of orbit. The SpaceX AI business is the company now. The rockets are the logo.
