SpaceX's AI Business Is Now Growing Faster Than Its Rockets

SpaceX is now, by its own numbers, as much an AI company as a rocket company. The firm reported $14.6 billion in revenue for the third quarter of 2026 on Tuesday, up 161 percent year-over-year, and said the growth came almost entirely from two places: its artificial intelligence business and its satellite internet arm.

The standout is a division SpaceX calls "SI," short for Super Intelligence. It brought in $7.6 billion in the quarter, an 830 percent increase from a year earlier. SpaceX attributed that surge to three things: new cloud services agreements, the acquisition of AI coding tool Cursor, and rising adoption of its Grok chatbot among both businesses and consumers.

For a company whose brand was built on reusable rockets, that's a striking shift in where the money comes from. SpaceX's actual Space division, the one that launches satellites and astronauts, posted just $1.8 billion in revenue, up a modest 6 percent year-over-year, and actually lost $7 million in income from operations. The SI business, by contrast, turned a $431 million operating profit.

The real engine of the company's finances, though, is Starlink. SpaceX's Connectivity business, which houses the satellite broadband service, generated $5.2 billion in revenue and $2.4 billion in operating income, the biggest profit of any of its three segments. SpaceX said it now has 13.6 million Starlink consumer subscribers.

A rocket company becomes an AI and broadband company

The numbers reflect a deliberate pivot that's been building for a while. SpaceX went public in June, and this is only its second earnings report as a publicly traded company, but the quarter it just closed was an eventful one. The company officially completed its $60 billion acquisition of Cursor, the AI coding assistant, folding it into the new SI division. It also launched the 13th flight of its Starship rocket and rolled out a new V5 residential dish for Starlink customers.

The pattern from the prior quarter is holding, too. On its Q2 call, SpaceX noted that Connectivity was the only one of its three segments not posting an operating loss, while both AI and Space were still in the red on that measure. This quarter, Connectivity remains the clear profit center, but SI has now flipped into the black as well, even as core Space operations slipped into a loss.

Behind that momentum is a strategic buildout. During the Q2 earnings call, SpaceX president Gwynne Shotwell laid out plans for a terrestrial mobile network intended to compete directly with T-Mobile, AT&T and Verizon. Combined with the Cursor deal and Grok's enterprise push, it points to a company stretching its ambitions well beyond orbit, into cloud computing, software tools, and consumer wireless.

Why this matters

SpaceX has always generated headlines for its rockets, but its balance sheet now tells a different story. The Space segment, literally the company's namesake business, is its smallest revenue contributor and the only one losing money on operations. Connectivity and SI are carrying the company financially, and SI's growth rate in particular, 830 percent in a single year, suggests SpaceX is positioning itself less as a launch provider and more as a diversified technology conglomerate that happens to also build rockets.

That framing matters for how investors and competitors read the company going forward. Elon Musk's broader empire has increasingly leaned on cross-pollination between his ventures, from xAI's Grok model to Tesla's compute needs, and SpaceX's SI business appears to be where some of that convergence is landing on the books. The Cursor acquisition gives SpaceX a foothold in the AI coding tools market, a crowded space where enterprise adoption has become a key growth lever for rivals too.

Musk's other major company, Tesla, reports its own earnings on Wednesday, giving a near-immediate point of comparison for how AI-related bets are playing out across his businesses this quarter.

For now, SpaceX's quarter makes clear that its most explosive growth isn't coming from anything that leaves the launchpad.
