Reflection AI will pay $150 million per month from July 2026 through 2029 for Nvidia GB300 chips and hardware at SpaceX’s Colossus 2 data center in Tennessee, in a contract worth up to $6.3 billion. The open-source-focused startup calls this its first major compute deal and one of the largest infrastructure commitments in the open AI space.

• Reflection AI committed to $150M/month from July 2026-2029 (up to $6.3B total) for Nvidia GB300 chips at SpaceX's Colossus 2 data center, with 90-day cancellation option after the first quarter
• This dwarfs in comparison to Anthropic ($1.25B/month) and Google ($920M/month) deals for the same facility, but is still notable as a small startup's first major compute deal
• Colossus began as xAI's private training hub before SpaceX absorbed it and opened capacity to outside labs once xAI's plans stalled
• Reflection positions itself as an open-weight lab, arguing this reduces vendor lock-in and geopolitical risk, gaining relevance after the U.S. blocked Anthropic's closed models Fable and Mythos
