Nebius Group Stock Soars 16% as AI Revenue Growth Hits 684%. Its Meta Deal Changes Everything.

Nebius Group’s Q1 blowout results — $399 million in revenue (up 684% YoY) and a $130 million adjusted EBITDA — sent its stock sharply higher and have broader implications for AI infrastructure markets. The five‑year, $27 billion Meta contract (a $12 billion firm commitment plus a $15 billion option) materially de‑risks capacity investment for Nebius and signals sustained corporate demand for large-scale GPUs and cloud compute. Nvidia’s $2 billion equity stake and Nebius’s raised capex guidance reinforce expectations for continued hardware demand, which could benefit GPU suppliers and cloud ecosystem partners. Overall, the report is a bullish catalyst for AI infrastructure plays and raises the stakes for firms supplying chips, data‑center capacity and AI services.
