The main catalyst was Nvidia’s planned $2 billion investment, which cemented Nebius’ position as a growing supplier in the global AI computing race. Market participants are increasingly viewing the company as part of a new wave of infrastructure providers benefiting from the boom in generative AI development.

Despite the sharp rise, trading activity suggests that momentum has not subsided, as investors continue to reprice AI infrastructure companies based on long-term demand forecasts rather than short-term volatility.

Strong financial growth supports the outlook

Nebius also delivered strong operating performance supporting the stock’s rise. In its latest quarterly results, the company reported revenues of $399 million, representing a staggering 684% year-over-year increase. Adjusted EBITDA was $129.5 million, indicating improved efficiency as a revenue volume.

Analysts often focus on adjusted EBITDA as a key indicator of whether AI-driven demand translates into sustainable profitability. In the case of Nebius, this metric served to reinforce the bullish narrative that its infrastructure model was beginning to mature alongside rapid expansion.
