HAWTHORNE, Calif. — Elon Musk has put a striking number on his vision for artificial intelligence: he now expects essentially all superintelligence-class compute to run in space. Asked on Monday about the share of AI computing that will eventually leave Earth, Musk said it "will round up to 100%."
The comment, made in reply to Sequoia Capital partner Shaun Maguire, extends a forecast Musk floated days earlier that monthly deployment of orbital compute will likely surpass all terrestrial capacity around the end of 2028. It reframes space not as a niche for communications satellites but as the primary home of humanity's most demanding computing — a continuation of the compute build-out already visible in projects like Colossus 2.
The Case for Computing in Space
Musk's logic is physical. Data centers on Earth are constrained by power, cooling, and land; in orbit, a satellite bathed in uninterrupted sunlight has abundant energy and the vacuum of space as a heat sink. Scale the solar arrays and the radiators, and the ceiling on compute rises far above anything a terrestrial campus can match.
SpaceX's answer is Star Mind, a planned line of AI satellites meant to fly in large formations, each carrying more than 250 kilowatts of solar power. Flown by the thousands — and eventually far more — such a constellation could host computing clusters unlike anything built on the ground.
From Forecast to Flight Hardware
Maguire, who has been circulating a detailed bottoms-up model of SpaceX's finances, said he plans to publish a systems-level analysis of orbital compute "over the next week or two." Musk's one-word reply — "Absolutely" — suggested the company welcomes the scrutiny.
Turning the vision into hardware is where SpaceX's unique advantages compound. Cheap, reusable launch is the enabler, and Musk has separately floated audacious delivery concepts, including a lunar mass driver to fling AI satellites into orbit at low cost. Whatever the launch method, the economics hinge on SpaceX's ability to put mass in space more cheaply than anyone else.
A Race SpaceX Is Positioned to Win
Musk is not alone in looking up. Google is pursuing orbital AI hardware of its own, with its first demonstration satellite slated to ride a SpaceX rideshare — a reminder that even rivals depend on SpaceX to reach orbit. That dual role, as both competitor and launch provider, gives SpaceX a vantage point no one else enjoys.
Musk was careful to frame the 100% figure as a forecast rather than a schedule, and Maguire's full write-up has yet to appear. But the trajectory is set. SpaceX has spent two decades driving down the cost of reaching orbit; now it intends to use that advantage to move the very engine of the AI era off the planet. More detail on the company's launch cadence and roadmap sits on its official site. If Musk is right, the data centers of the 2030s may orbit overhead rather than hum in the desert.
