The startups racing to put AI data centers in space before Big Tech gets there

Starcloud, Axiom Space, Lonestar, and others are betting they can stake claims in orbit before Google and SpaceX scale up

A startup nobody had heard of 17 months ago is now valued at $1.1 billion and has already put a GPU in orbit. Starcloud, a Redmond, Washington company that went through Y Combinator's summer 2024 cohort, raised $170 million in a Series A in March 2026 and has filed with the FCC for an 88,000-satellite constellation. In November 2025, it became the first company to run an Nvidia $NVDA H100 GPU in orbit.

The ambition is clear. So is the competition. Google $GOOGL plans prototype satellites by 2027. SpaceX has filed for up to a million. Jeff Bezos has sketched out gigawatt-scale orbital facilities for Blue Origin. A handful of startups are racing to establish positions in orbit before the largest companies in tech arrive in force.

Their strategies differ sharply — and those differences reveal what each company believes the market actually is right now, before launch costs fall far enough to make AI data centers in space viable at scale.

Starcloud is the farthest along

Starcloud has the strongest claim to operational hardware. Its 60-kilogram Starcloud-1 satellite, launched aboard a SpaceX Falcon 9 on Nov. 2, 2025, carried an Nvidia H100 GPU and ran multiple AI workloads in orbit — including training a small language model on the complete works of Shakespeare, according to Introl's February 2026 analysis of the orbital data center market. The company, formerly Lumen Orbit before a rebrand in early 2025 to avoid a trademark conflict, is planning its next satellite........
