Nebius Group NV (NASDAQ:NBIS) is trading like the math still hasn't caught up to the story: roughly $46 billion in marquee AI infrastructure deals against a market cap just above $28 billion.

The $27 Billion Meta Pact

Meta Platforms, Inc. (NASDAQ:META) has agreed to spend up to $27 billion over five years on Nebius AI infrastructure, one of the largest single AI cloud commitments in the market. 

The deal, announced Monday, includes $12 billion of dedicated capacity beginning in 2027 and up to $15 billion in additional on‑demand capacity as Meta races to scale frontier models on Nvidia-powered "AI factories."

For Nebius, this is locked-in hyperscaler demand that underwrites a massive build-out of next-gen data centers.

The $17 Billion Microsoft Agreement

Before Meta, Microsoft Corp. (NASDAQ:MSFT) had already validated Nebius with a five-year AI infrastructure contract worth about $17.4 billion. Certain options could lift the total closer to $19.4 billion. 

Nebius will supply GPU capacity from its Vineland, New Jersey, facility, alleviating bottlenecks for Microsoft in AI compute without adding to its own capex. 

CEO Arkady Volozh has framed the Microsoft deal as central to Nebius' core AI cloud model, providing long-duration, highly visible revenue to fuel expansion into 2026 and beyond.

Nvidia's $2 Billion Strategic Bet

Then Nvidia stepped in with a $2 billion equity investment and deep technical alliance, sending NBIS shares sharply higher. 

The partnership gives Nebius early access to Rubin-generation platforms, Vera CPUs, and BlueField systems. It also targets more than 5 gigawatts of Nvidia-powered capacity by 2030, effectively positioning Nebius as a flagship "neocloud" for the agentic AI era.

Do The Math

Put together, Nebius has roughly $46 billion of contracted or potential deal value from Meta, Microsoft, and Nvidia. Hold that against a public equity value of about $28 billion. 

These are multi‑year, capacity-based agreements with big capex requirements and execution risk. For investors, the simple spread between backlog and market cap highlights how quickly Nebius has gone from niche neocloud to one of AI's most levered infrastructure plays.

NBIS Price Action: Nebius shares were up 11.87% at $126.37 at the time of publication Monday, according to Benzinga Pro data.
