Reflection AI Signs $6.3B SpaceX Compute Deal, Becoming Third Major Lab at Colossus 2
Summary
- • Open-source AI startup Reflection AI signs a $150M/month compute deal with SpaceX worth up to $6.3 billion through 2029.
- • Reflection will access Nvidia GB300 chips at SpaceX's Colossus 2 data center near Memphis, Tennessee, starting July 1, 2026.
- • The deal is smaller than SpaceX contracts with Anthropic ($1.25B/month) and Google ($920M/month), cementing Colossus 2 as a shared frontier AI hub.
- • Reflection AI, founded by ex-DeepMind researchers in 2024, frames the deal as a commitment to open-weight AI amid rising demand after the U.S. government banned Anthropic's closed Fable and Mythos models.
Details
SpaceX–Reflection AI compute deal
Reflection AI signs a $150M/month compute contract with SpaceX for access to Nvidia GB300 chips at Colossus 2, beginning July 1, 2026.
$6.3B total deal value
The deal is worth up to $6.3 billion if both parties maintain it through 2029, payable at $150 million per month.
Peer deal comparison: Anthropic & Google
Anthropic pays SpaceX $1.25B/month and Google pays $920M/month under similar contracts, all running through July 2029.
Colossus 2 data center, Memphis TN
SpaceX's Colossus 2 hosts Nvidia GB300 chips and was originally built by xAI for internal AI work before becoming a compute rental business.
90-day flexible exit clause
Either party can cancel the contract with 90 days' notice after the first three months — a clause also present in SpaceX's Anthropic and Google deals.
SpaceX pivots to AI compute marketplace
After xAI's internal AI efforts faltered, SpaceX began renting out Colossus chip capacity to frontier AI labs, becoming a major third-party compute provider.
Open-weight AI positioning
Reflection frames its open-weight model strategy as a direct response to the U.S. ban of Anthropic's closed Fable and Mythos models, arguing enterprises now recognize the risks of closed-model dependence.
Reflection AI background
Founded in 2024 by two former Google DeepMind researchers; this is the company's first compute deal and largest public strategic commitment to date.
Financials, infrastructure details, and strategic context for Reflection AI's $6.3B compute deal with SpaceX at the Colossus 2 data center.
What This Means
SpaceX has quietly become one of the most important AI infrastructure players in the world, with three long-term compute contracts worth tens of billions of dollars — all anchored at the Colossus 2 facility that began as Elon Musk's internal AI project. Reflection AI's entry at $150M/month places an open-weight startup on frontier-level infrastructure footing alongside the largest closed labs, validating that open-source frontier AI can attract serious capital. The flexible exit clauses on all three deals are a telling signal: despite the headline numbers, all parties are pricing in significant uncertainty about AI's long-term revenue trajectory and leaving themselves escape hatches.
