Reflection AI will pay $150 million monthly from July 2026 through 2029 for Nvidia GB300 chips and hardware at SpaceX’s Colossus 2 data center, in a contract worth up to $6.3 billion and cancellable after three months with 90 days’ notice. The startup says this deal underpins its open-weight AI strategy, positioning it against closed labs like Anthropic and OpenAI.

• Reflection AI will pay SpaceX up to $6.3 billion ($150M/month, 2026-2029) for GB300 chip access at Colossus 2, but either party can cancel with 90 days' notice after the first quarter.
• Reflection is the first open-weight AI lab to land a compute deal in the same tier as Anthropic ($1.25B/month) and Google ($920M/month) with SpaceX.
• The Colossus facility was originally built for xAI, and its underused capacity is now being sold to outside labs since xAI's own projects have lagged.
