Reflection AI has signed a large compute agreement with SpaceXAI, becoming the latest outside AI company to use the Colossus 2 data center near Memphis.

The reported deal gives Reflection access to Nvidia GB300 chips and related hardware starting July 1, 2026. TechCrunch and CNBC both report that Reflection will pay $150 million per month through 2029 if the arrangement runs its full course, putting the potential contract value at about $6.3 billion. The companies can terminate the agreement with 90 days' notice after the first three months.

The agreement is notable because Reflection is trying to build frontier-scale open-weight models, a strategy that requires large clusters of current-generation AI accelerators. Instead of waiting on new capacity from traditional cloud providers, the startup is buying immediate access to infrastructure that SpaceX built around Colossus.

For SpaceXAI, the contract adds another customer to a commercial compute business that is emerging alongside its own model work. The company has been turning surplus or expanded AI infrastructure into leased capacity for other labs, making high-end chips a revenue line rather than only an internal research expense.

Reflection framed the deal as a way to push open models closer to closed frontier systems. That remains an execution question: the agreement secures hardware, but the quality and release terms of Reflection's future models will determine whether the compute translates into a meaningful open-weight alternative.
