Nvidia Takes 9.3% Stake in Nebius, Boosting AI Cloud Partner

Nvidia has disclosed a material equity stake in Nebius Group, the cloud infrastructure specialist, according to an SEC filing released on Tuesday. Nvidia owns 22,256,412 shares of Nebius through a combination of common stock and prefunded warrants, which amounts to a 9.3% stake in the company currently valued at about $5 billion（約8000億円）. The news sent Nebius shares up 18.91% in trading.

The investment builds on a strategic partnership announced between the two companies in March. Under that deal, Nvidia and Nebius are working to deploy high-performance cloud computing infrastructure specifically designed for artificial intelligence workloads. At the time of the partnership announcement, Nvidia CEO Jensen Huang described the effort in expansive terms: "Nebius is building an AI cloud designed for the agentic era, fully integrated from silicon to software and powered by Nvidia's next-generation accelerated compute. Together, we are scaling the cloud to meet the surging global demand for intelligence."

Nebius has already built substantial revenue momentum in the cloud infrastructure space. The company has secured over $40 billion（約6.4兆円） in contracted revenue from customers, with partnerships announced alongside major tech companies including Microsoft and Meta Platforms. Nvidia's equity stake appears designed to deepen the strategic relationship and signal to the market that Nebius is a credible infrastructure provider as global demand for AI compute continues to grow.

Nvidia's disclosure of a 9.3% stake in Nebius reflects the AI giant's strategic focus on the cloud infrastructure layer that underpins AI workload deployment. The March partnership announcement positioned Nebius as a specialist in building AI-optimized cloud infrastructure, and Nvidia's equity investment signals the company sees material upside in Nebius's ability to scale that business. The timing is significant: with Nebius already holding over $40 billion（約6.4兆円） in contracted revenue from major tech players like Microsoft and Meta Platforms, the stake represents a vote of confidence in the company's execution during a period when demand for AI compute is described by Nvidia CEO Jensen Huang as surging globally. The 18.91% one-day jump in Nebius stock reflects investor recognition that Nvidia's backing strengthens the company's position as a credible infrastructure provider in the race to meet enterprise AI demand.
