Nebius Group shares jumped between 15% and 18% on Thursday after the company reported first-quarter results that exceeded analyst expectations [1, 2, 3].

The surge reflects growing investor confidence in "neocloud" providers as the demand for artificial intelligence infrastructure accelerates. The stock's performance suggests that Nebius is successfully scaling its operations to compete with larger cloud entities.

Nebius Group, traded on the NASDAQ under the ticker NBIS, reported Q1 2026 revenue of $399 million [4]. This figure surpassed the consensus analyst estimate of $388.6 million [5]. The company also reported a seven-fold increase in revenue year-over-year [6].

Beyond financial gains, the company announced significant infrastructure growth. Nebius provided power guidance of 4 GW for 2026 [7]. This expansion includes the addition of 1.2 GW of power capacity in Pennsylvania [8].

Market reactions varied slightly across trading windows. Shares surged nearly 15% in pre-market trading [3], while other reports indicated the stock rose as much as 18% [1] or 16% [2]. The earnings report was scheduled for Wednesday, May 13 [9].

The company's growth trajectory is tied to its ability to secure massive amounts of power, which is a primary bottleneck for AI data center expansion. By securing gigawatt-scale capacity, Nebius aims to provide the computational power necessary for training large-scale AI models.

The rapid rise in Nebius's valuation underscores a shift in the AI market where power capacity is becoming as valuable as hardware. By securing 4 GW of power and beating revenue estimates, Nebius is positioning itself as a critical infrastructure layer for AI developers who cannot access the limited capacity of hyperscalers like AWS or Azure.
