Nebius Rides the Sovereign AI Wave to a Nasdaq-100 Debut and a 6x Stock Surge

Nebius stock rallies 22% as European AI cloud provider secures Nasdaq-100 inclusion, $17.4B Microsoft deal, and $2.47B quarterly capex for data center expansion.

When Nebius shares touched €260.75 on Thursday, they capped a week that crystallised the company’s transformation from a €38 penny stock to a Nasdaq-100 contender. The 22.23% weekly rally that followed left the stock at €245.20 on Friday, with the index inclusion scheduled for 22 June adding a fresh layer of institutional credibility. But behind the price action lies a structural bet that goes far beyond mere GPU leasing.

Europe’s hunger for sovereign AI infrastructure has created a unique opening. Governments and enterprises are increasingly wary of running sensitive models on US-controlled cloud platforms, and Nebius — with its Finnish data centres and compliance with the EU AI Act and GDPR — offers what one analyst calls a “safe harbour” for regional data. The SemiAnalysis ClusterMAX ranking from April 2026 graded it the only Gold-tier cloud resident in the EU, a technical endorsement that signals parity with hyperscalers on performance and scalability.

That positioning is translating into revenue at a pace that defies the usual startup trajectory. First-quarter 2026 sales hit $399 million, up from $50.9 million a year earlier, while adjusted EBITDA swung from a loss of $53.7 million to a profit of $129.5 million. The operating numbers are tempered by a clean net loss of $100.3 million and capital expenditure that reached $2.47 billion in the quarter alone — a sign of the enormous upfront cost of building AI compute at scale.

Nebius now plans to bring between 800 megawatts and one gigawatt of capacity online by year-end, up from a contractual pipeline that already exceeds four gigawatts. To feed that expansion, the company is pouring £1.7 billion into three Nvidia-powered data centres in the UK, alongside major US sites in Missouri and Pennsylvania and its existing Finnish hub. The spending is backed by long-term customer commitments: Microsoft has signed on through 2031 for $17.4 billion, and Meta committed up to $27 billion over five years. Nebius intends to fund the estimated $25 billion in 2026 capex through asset-backed financing against those contracts, potential corporate bonds, and customer prepayments.

The acquisition of Eigen AI, announced on 1 May and closed on 10 June, adds a software layer to the hardware story. By folding inference and post-training optimisation into its managed platform, Nebius Token Factory, the company is reaching for the higher-margin end of the AI stack — the part where raw compute gives way to production-ready services. With inference workloads expected to account for nearly two-thirds of AI compute demand in 2026, owning that layer could fundamentally alter the business model.

That transformation has not gone unnoticed by the market — or by insiders. The stock’s annualised 30-day volatility sits at 109%, and the relative strength index at 67.1 points to an overheated name. Traders also noted that insiders sold $132 million worth of shares in the last quarter. The bull case, as sketched by Nebius’s own positioning, is that it is one of the few European firms that can deliver data sovereignty as a technical reality, not a marketing slogan — with in-house GPU server engineering capacity the market still underestimates. The bear case is simpler: the capital commitments are enormous, the execution window is tight, and the stock is now less than 6% shy of its 52-week high.

For 2026, management has guided for revenue between $3.0 billion and $3.4 billion, with adjusted EBITDA margins of around 40%. A market capitalisation of €63.5 billion already embeds assumptions that the infrastructure buildout, the inference platform, and the sovereign cloud strategy all deliver on schedule. The next proof points will come not in trading sessions, but in the data centres themselves.
