AI Data Centers Head to Space as Major Tech Giants Race to Orbit

What Happened The space-based computing revolution has moved from concept to active development, with several major players making concrete moves toward orbital AI infrastructure: Starcloud became the first company to successfully train a large language model in space using an NVIDIA H100 GPU in 2025, proving the technical feasibility of the concept. The company has since filed with the FCC for a constellation of up to 88,000 satellites. SpaceX submitted FCC applications in January 2026 for millions of satellites dedicated to space-based computing, leveraging their Starlink manufacturing and launch capabilities.
