Microsoft has finalized a $19.4 billion deal with Nebius Group NV, securing access to over 100,000 of Nvidia’s latest GB300 chips, Bloomberg reports. The agreement is part of Microsoft’s effort to address the global shortage of AI data center capacity and enhance its ability to deliver advanced AI services to customers.

This deal reflects Microsoft’s broader strategy of leveraging neocloud providers for rapid AI infrastructure expansion. The company has already committed over $33 billion to firms such as CoreWeave, Nscale, Lambda, and Nebius, which specialize in providing AI-focused server power. By partnering with these providers, Microsoft can scale quickly without waiting for new data centers, while managing costs as operational expenditures rather than heavy capital investments.

“We are very much in land-grab mode in the AI space,” said Scott Guthrie, head of Microsoft’s cloud division. “We’ve made the decision that we don’t want to be constrained in terms of capacity.”

Following the announcement, Nebius shares rose 5.5% in New York trading, while Microsoft’s stock remained largely unchanged. The deal underscores Microsoft’s aggressive push to secure computing power and strengthen its position as a global leader in AI cloud infrastructure amid surging demand.
