Starcloud, a startup specializing in orbital data centers capable of AI processing, has secured an additional $250 million funding, extending its March 2026 Series A round which initially raised $170 million. This extension catapults the company’s valuation to $2.3 billion and will support the expansion of its manufacturing capabilities as well as advance its Starcloud-3 satellite, designed for deployment on SpaceX’s upcoming Starship rocket. CEO Philip Johnston emphasized the critical need to secure launch contracts amid a tightening rocket launch market, as SpaceX plans to retire its Falcon 9 rockets by 2028, limiting available launch opportunities.

The company holds FCC approval to operate up to 88,000 satellites and is actively pursuing contracts to lock in launch capacity, including rideshare missions slated for 2027, which will carry Starcloud’s 8 kW compute satellites. These satellites are intended to run AI inference for clients such as U.S. government agencies. Johnston mentioned that Starcloud is also exploring dedicated Falcon 9 launches and other providers’ services to sustain its ambitious deployment schedule given the current scarcity of reliable rocket services, with key competitors like Blue Origin and ULA’s new vehicles not yet fully operational.

Starcloud’s vision hinges on SpaceX’s Starship rocket succeeding as a reusable, cost-effective platform for large-scale orbital data center deployment. While Starship remains unproven with its first reflights expected by late 2026 or early 2027, the company is banking on its improved launch economics to compete with terrestrial data centers. Industry leaders including Nvidia and Cisco participated in the funding round, with Nvidia reportedly investing $25 million—a sign of confidence given Starcloud’s unique deployment of Nvidia H100 GPUs in orbit, making it the first to train AI models on these devices in space.

The startup is also collaborating with Nvidia on the Vera Rubin Space-1 chip, which is being designed specifically for space conditions and is expected to launch by late 2028. Starcloud’s engineers are focused on critical design challenges such as thermal management, radiation shielding, and survivability under launch stresses. The company is growing steadily, operating out of a large facility in Woodinville, Washington, near major satellite manufacturers like SpaceX and Amazon. This strategic positioning positions Starcloud to lead the emerging market for AI-driven space-based computing despite the current constraints on launch infrastructure.
