AI1: data centres where the sun never sets
AI1 is SpaceX's wager that the cheapest place to run AI compute is orbit: unlimited solar power, free cooling, and no grid permits. It's the youngest segment — and the one repricing the stock.

The model
Compute-as-a-service, launched in-house
Each AI1 cluster packages GPUs, solar arrays and radiators into modules launched on SpaceX's own vehicles — the same vertical-integration play that made Starlink possible. Revenue comes from multi-year reserved-compute contracts with AI labs and hyperscalers. The bull case: as Starship drops launch costs below $100/kg, orbital compute undercuts terrestrial data centres on power-constrained workloads. The bear case: radiation, bandwidth and servicing costs eat the margin.
Risks & watch items
What the market is watching
- Cluster 2 uptime data — the 99.9% SLA claim needs months of proof.
- Tenant economics: contract terms remain undisclosed; watch the Q2 earnings call for first revenue disclosure.
- Orbital debris and licensing scrutiny scale with every cluster.
