The agreement runs through 2029, gives Reflection access to Nvidia GB300-powered Nebius infrastructure, and comes as Nebius expands AI cloud capacity amid persistent GPU supply constraints.
Reflection has signed a multi-year deal worth more than $1 billion with Nebius Group for AI computing capacity through 2029, securing access to Nebius infrastructure using Nvidia GB300 chips for AI model development. The agreement adds to Reflection's earlier multi-billion dollar chip acquisition deal with SpaceX and comes as the startup pursues a reported $2.5 billion fundraising at a $25 billion valuation. The deal also highlights Nebius's broader push as an AI-focused cloud provider at a time when startups are seeking alternatives to larger hyperscalers amid reported GPU shortages. Nebius, which spun off from Yandex in 2024, has said it partnered with Nvidia on March 11, 2026, to deploy more than 5 gigawatts of Nvidia systems by the end of 2030 and is investing about $2.3 billion to build UK-based capacity targeting 65 megawatts by 2027 using Nvidia Blackwell Ultra infrastructure.
