Nebius Hits Record High After $17.4B Microsoft AI Deal

Nebius Group’s (NBIS.O) shares surged 43% to a record $91.75 on Tuesday after striking a $17.4 billion, five-year deal with Microsoft to supply AI infrastructure. The contract could rise to $19.4 billion if Microsoft scales up demand, making it one of the largest partnerships in the rapidly growing AI data center sector.

Deal Impact

  • Nebius will supply dedicated GPU infrastructure from its new Vineland, New Jersey data center, starting later this year.

  • Microsoft has been facing AI cloud shortages and is relying on external providers like Nebius and CoreWeave to meet client demand.

  • Rival CoreWeave’s shares rose 4.4% in parallel, reflecting investor optimism for the broader AI cloud sector.

Market Significance

  • Nebius stock has more than doubled in 2025, driven by global AI demand and investor enthusiasm.

  • Analysts said the deal de-risks Nebius’ capacity expansion and cements its position as a key supplier to hyperscalers and AI labs.

  • BWS Financial analyst Hamed Khorsand called it “unprecedented clarity on long-term revenue potential.”

Strategic Outlook

  • The agreement builds on Nebius’ full-stack AI cloud model, which provides Nvidia-powered computing, storage, and developer tools.

  • CEO Arkady Volozh said the deal will accelerate AI cloud growth from 2026 onward, reinforcing Nebius’ expansion strategy.

  • Founded from the spinoff of Yandex assets, Amsterdam-based Nebius is now seen as a leading independent AI infrastructure provider.

Trump EPA Proposes Faster Permitting to Speed AI Infrastructure Buildout

The Environmental Protection Agency (EPA) under President Donald Trump unveiled a proposal on Tuesday to accelerate permitting for AI-related infrastructure, allowing companies to begin construction of certain facilities before receiving Clean Air Act air permits.

Key elements of the proposal

  • Early construction allowance: Firms could start building parts of projects not directly tied to emissions before permits are finalized.

  • Target facilities: Power plants, manufacturing hubs, and data center infrastructure.

  • Objective: Reduce permitting delays that have long been cited as barriers to large-scale projects.

EPA Administrator Lee Zeldin said:

“For years, Clean Air Act permitting has been an obstacle to innovation and growth. We are continuing to fix this broken system.”

Context

  • The proposal follows the EPA’s “Powering the Great American Comeback” initiative launched six months ago, prioritizing power generation for AI-driven data centers.

  • The U.S. and China remain locked in a tech arms race, with AI development central to both economic and national security ambitions.

  • Rapid AI adoption is fueling surging demand for power, putting pressure on utilities and grids nationwide.

Regulatory background

  • Under the New Source Review program, companies cannot normally begin construction of major facilities before securing air permits.

  • The Trump administration is pushing a deregulatory agenda, including repeals of scientific and legal bases for greenhouse gas regulation — a move widely criticized by environmentalists.

Implications

  • Supporters argue the change will fast-track AI infrastructure, critical for U.S. competitiveness.

  • Critics warn it could weaken environmental safeguards and increase pollution risks while AI-related energy demand skyrockets.

Nebius Signs $17.4 Billion AI Infrastructure Deal With Microsoft

Nebius Group (NBIS.O) announced on Monday a five-year agreement with Microsoft (MSFT.O) to provide GPU infrastructure capacity, a deal valued at $17.4 billion that could expand to $19.4 billion if additional services are acquired. The news sent Nebius shares surging more than 47% in after-hours trading.

The partnership highlights the escalating demand for high-performance AI compute as tech giants race to secure infrastructure for training and running advanced models. Under the deal, Microsoft will gain access to Nebius’ dedicated GPU infrastructure from a new Vineland, New Jersey data center starting later this year.

Nebius specializes in offering AI cloud services powered by Nvidia GPUs, combining computing, storage, management tools, and in-house designed hardware to support AI developers. CEO Arkady Volozh said the deal is not only financially significant but also positions Nebius for accelerated AI cloud growth from 2026 onwards.

Microsoft already stands as the largest customer of CoreWeave (CRWV.O), another AI infrastructure provider. The Nebius agreement suggests the company is broadening its supply chain to mitigate risks as hyperscaler demand grows.

Amsterdam-based Nebius was formed after the split of Russian tech giant Yandex, and has been expanding rapidly into the U.S. and European AI infrastructure markets.
