SpaceX Aims for 1 GW of Orbital AI Compute by 2027

Elon Musk reiterated that space is the only way to scale artificial intelligence infrastructure and that SpaceX is targeting 1 gigawatt of orbital compute per year by late 2027. The company revealed a first-generation satellite, AI1, about 70 meters across, designed to carry modular compute hardware.

Musk cited limits on terrestrial power and land. He noted solar arrays in orbit collect roughly five times the power available on the ground and do not face nights or weather, adding that “it’s always sunny” in space.

SpaceX opened an 11-million-square-foot factory in Bastrop, Texas, called Gigasat to mass-produce AI satellites beginning in 2027. The company is targeting 1 GW of orbital compute per year by late 2027, aims for 100 GW annually by 2030 and has discussed eventual terawatt-level capacity; Musk cautioned the timetable could be optimistic.

AI1 spans about 70 meters and carries a compute payload that averages roughly 120 kilowatts and peaks at about 150 kilowatts. The craft is built to accept interchangeable compute modules rather than being tied to a single chip supplier. Musk described the AI satellite as “much simpler than a Starlink satellite.”

SpaceX has filed with regulators for a constellation that could include up to one million satellites, projecting as much as 100 GW of capacity under that plan.

SpaceX raised roughly $75 billion in its Nasdaq debut on June 12 and closed with a valuation near $2.1 trillion. The company holds 18,712 bitcoins in its corporate treasury; Tesla holds 11,509 bitcoins.

Some analysts and engineers identified technical hurdles that could slow deployment, including thermal management in vacuum, radiation effects on electronics, launch cadence and the cost of launches, and the logistics of in-orbit repair and maintenance. They warned these challenges could delay large-scale orbital compute for years or decades and noted most current AI capacity remains in terrestrial data centers.

If the Bastrop factory begins shipping complete AI satellites by late 2027 as planned, the program will provide an early operational test of SpaceX’s orbital compute approach.
