SpaceX reveals “AI1,” an orbital data-center satellite, ahead of its IPO

Elon Musk unveiled AI1, the first generation of SpaceX’s orbital AI compute platform — a solar-powered satellite with a 70-meter wingspan that sustains about 120 kilowatts of compute (peaking near 150) and sheds heat through a liquid radiator into space. Musk called it “much simpler than a Starlink satellite,” with two prototypes targeted for early 2027 and a constellation to follow. The reveal lands the same week SpaceX prices its IPO, with shares set to debut on the Nasdaq under the ticker SPCX.
