Starcloud Raises $450M for Orbital AI Compute While Racing Falcon 9's 2028 Retirement
Starcloud has raised $450M in total after closing a $250M extension to its March Series A. The round values the orbital data centre company at $2.3B and includes NVIDIA among eleven extension investors.
The strategic signal from NVIDIA’s participation is specific. Starcloud is the only known company running an NVIDIA H100 data-centre GPU in orbit, launched in November 2025. The operational data from that hardware feeds directly back to NVIDIA as it develops the Space-1 Vera Rubin Module, its first GPU designed for the space environment.
CEO Phillip Johnston described the NVIDIA relationship to TechCrunch in those terms: Starcloud’s H100 experience is the reference point for what NVIDIA’s space-grade silicon needs to handle.
What Starcloud Is Building
The company’s thesis is that orbital compute can serve AI inference workloads across large geographic footprints without dependency on ground-based power or fibre infrastructure. Starcloud-3, its largest planned spacecraft, is designed to fly on SpaceX’s Starship once that vehicle reaches commercial cadence.
Starcloud has also completed what it describes as the first model training run on an orbital GPU. The H100 in orbit is not a scaled-down space-grade variant; it is the same hardware used in terrestrial clusters, making the performance data directly comparable to ground deployments.
The 2028 Problem
Johnston identified the critical constraint in comments to TechCrunch: “One of the biggest costs is now on securing your launch capacity. Launch is pretty constrained right now because the Falcon 9 program is scheduled to end in 2028.”
Starship is the intended solution. SpaceX’s larger vehicle is designed to reduce per-kilogram launch costs to levels that make orbital data centre economics viable at scale. But Starship has not yet demonstrated the commercial cadence Starcloud’s scaling plan requires, and the overlap between Falcon 9’s retirement and Starship reaching consistent operational tempo is where the plan is most exposed.
The $250M extension is partly about manufacturing capacity for Starcloud-3 and future spacecraft, partly about locking in launch commitments before the available slots on Falcon 9 disappear. At $2.3B valuation with $450M raised and operational orbital hardware, Starcloud leads its category by margin. Whether it can scale fast enough before its primary launch vehicle retires is the question the next 24 months will answer.
