Nebius Stock Jumps Over 27% on Billion-Dollar AI Deal and Strong Sector Demand

Shares of Nebius (NBIS) surged as much as 28.7% in morning trading, driven by a confluence of positive factors including a major new client contract, the removal of a key selling overhang, and strong sector-wide demand for artificial intelligence infrastructure.

Key Catalysts Behind the Move

The rally was ignited by several company-specific and market developments. According to a report from Investing.com, the primary drivers include:

• A major client agreement: Nebius disclosed a multi-year deal to provide more than $1 billion of GPU-based computing capacity to Reflection AI. The contract, which runs through 2029, provides investors with contracted, long-duration revenue, signaling strong enterprise demand for the company's services.
• Relief from selling pressure: The news followed reports that the Situational Awareness fund had collapsed, which may have been responsible for recent forced selling in the stock. The end of this selling pressure likely removed a significant headwind for the share price.

Microsoft Earnings Provide Sector-Wide Lift

A powerful tailwind came from technology giant Microsoft, which reported fiscal fourth-quarter results that beat expectations. Microsoft's Azure cloud revenue growth accelerated to 43%, with the division crossing $100 billion in annual revenue for the first time.

As Nebius operates as a specialized GPU-focused "neocloud" provider, Microsoft's strong performance was seen by investors as direct validation of sustained enterprise demand for the entire AI compute ecosystem. This positive sentiment was amplified by a broad market rally, with the Nasdaq Composite climbing 2.3%.

Technical and Sentiment Backdrop

The sharp move also occurred from a technically oversold position. Nebius shares had declined more than 30% from their mid-July highs, closing near $148 in the prior session, which attracted dip-buyers on Tuesday's positive news flow.

Analyst sentiment was already constructive heading into the session, with a consensus Buy rating on the stock. Northland Capital Markets holds one of the highest price targets at $410, according to the report. The combination of fundamental catalysts and a favorable technical setup propelled the stock to an intraday high of $195.89.
