Key Data Points
Nvidia and Nebius announced a strategic partnership in March. The two companies are working together to deploy high-performance cloud computing infrastructure geared toward artificial intelligence (AI) workloads.
"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," Nvidia CEO Jensen Huang said at the time. "Together, we are scaling the cloud to meet the surging global demand for intelligence."
The tech giants have an insatiable appetite for compute
Nvidia isn't the only AI leader Nebius has partnered with. The neocloud provider has announced multibillion-dollar infrastructure deals with tech titans like Microsoft and Meta Platforms.
In all, Nebius has already secured over $40 billion in contracted revenue from its customers. With the AI boom still in its early innings, that figure is set to grow far larger in the coming years.
