Nebius Group N.V. (NASDAQ: NBIS) delivered one of the standout single-session performances of any stock in the market on Monday, May 4, 2026, surging 13.24% to close around $155. The move came amid a broad market sell-off driven by Middle East tensions and rising oil prices, making the NBIS outperformance all the more striking for investors tracking the AI infrastructure sector.
Three distinct catalysts drove the May 4 surge: Nebius Group’s acquisition of Eigen AI, a Goldman Sachs price target increase following a Meta AI infrastructure contract, and Nebius’s 2025 annual recurring revenue exceeding internal guidance while funding 2026 capex without requiring further equity dilution.
The Eigen AI acquisition, announced in the days before the close, was valued at approximately $643 million in a cash-and-stock transaction, integrating Eigen’s inference and post-training optimisation capabilities into Nebius’s Token Factory platform. The deal is designed to shift Nebius toward higher-margin Platform-as-a-Service revenue, a critical inflection point for a company still scaling its data centre footprint aggressively.
The broader Nebius investment case is anchored in a contracted backlog that approaches extraordinary scale. The company holds deals approaching $27 billion with Meta and $19.4 billion with Microsoft, alongside a $2 billion Nvidia equity investment that serves as a third-party validation of its AI infrastructure thesis. Nebius closed a $4.34 billion convertible debt funding round to support its 2026 capital expenditure programme, with an executive describing the company as “well-funded” to execute its buildout plans.
New facility announcements included the construction of a 310-megawatt AI factory in Lappeenranta, Finland, which would rank among the continent’s largest AI data centres. The Finland expansion extends a pattern of European build-out as the continent races to develop indigenous AI computing capacity.
Q1 2026 financial results are scheduled for release on May 13, 2026, with analysts projecting considerable year-over-year revenue growth from a base that already showed the company transitioning rapidly from pre-revenue speculation to contracted infrastructure delivery. The stock’s 52-week range of $23.25 to $168.71 captures the extraordinary trajectory of a company that was relisted as Nebius after its separation from Russian tech firm Yandex. The May 4 surge pushed it back toward the top of that range and raised fresh questions about whether the next leg higher could challenge and ultimately break through the all-time high.
