The numbers are specific. Beginning July 1, 2026, Reflection AI will pay SpaceX $150 million per month for dedicated GB300 compute access at Colossus 2. The contract runs through December 2029, roughly 42 months, putting the full-term value at approximately $6.3 billion. The agreement includes a termination clause allowing either party to exit after the initial period, which means actual payments may fall short of the headline figure.
$6.3 billion. That’s what non-hyperscaler compute costs when you’re training at frontier scale.
Reflection AI is an open-source AI startup. Reflection AI stated the agreement provides access to GB300 chips to train what it describes as frontier open-source models; that framing is the company’s own characterization, not an independently verified capability claim.
The real story is what this deal reveals about compute pricing outside the hyperscaler ecosystem. AWS, Azure, and GCP have long set the reference price for GPU access. SpaceX’s Colossus 2, a separate facility from xAI’s Colossus supercomputer, is now offering an alternative at $150 million per month, and Reflection AI chose it. That’s a market signal, not just a contract.
SpaceX isn’t new to commercial compute. The Reflection AI deal adds a named anchor tenant at a facility that only entered public awareness with SpaceX’s S-1 filing earlier this year. Hyperscalers are becoming the capital infrastructure of AI deployment — SpaceX is now competing for exactly that position from outside the cloud establishment.
What to Watch
Analysis
This is SpaceX's second confirmed commercial compute tenant at Colossus 2 within 90 days of its Nasdaq debut, following the previously reported Google deal. A third anchor tenant before Q4 2026 would shift this from a pair of high-profile contracts to a repeatable commercial pipeline.
The catch is the single-facility concentration. Colossus 2 is where this deal lives. Any operational disruption at that facility, power, regulatory, or otherwise, becomes Reflection AI’s problem with limited recourse.
SpaceX has assembled a compute stack that includes its own data center infrastructure and confirmed anchor tenants within 90 days of its Nasdaq debut. If the Reflection AI contract runs its full term, Colossus 2 will have generated more commercial compute revenue than many enterprise cloud divisions report in a year. Watch whether a third major tenant is announced before Q4 2026 — that would confirm SpaceX’s compute business is a pipeline, not a pair of one-offs.
