In the race to build AI infrastructure for the next decade, geography is destiny. America has its hyperscalers. China has its state-backed champions. And Europe, acutely aware that it has already ceded the consumer cloud to Amazon, Microsoft, and Google, faces an existential question: who builds the AI cloud on the continent? The answer comes from a Dutch-registered company with Russian engineering roots, a Nasdaq listing, and a $2 billion seal of approval from Jensen Huang himself.
Nebius Group is on pace to generate $3.0 to $3.4 billion in revenue this fiscal year, a sixfold increase from the $529.8 million it posted in FY2025, which was itself a 54x explosion from the $9.8 million it reported just two years prior. Those numbers alone explain the Street's attention. But the surface-level revenue story obscures something more consequential: Nebius is assembling the only defensible, full-stack sovereign AI infrastructure on European soil, building moats its competitors cannot easily cross.
The most important relationship in Nebius's arsenal is with NVIDIA. In March 2026, the GPU giant disclosed a $2 billion passive stake representing roughly 9.3% of shares outstanding. This is not merely financial — it grants Nebius privileged access to NVIDIA's silicon allocation pipeline at a time when every AI company on earth fights for H100s and B200s. When Jensen Huang appeared via video at Nebius's Inflection 2026 event in San Francisco, the message was unambiguous: NVIDIA has chosen its European champion.
GPU access is critical, but the binding constraint on AI infrastructure is power. Nebius has already contracted over 3.5 gigawatts of capacity across seven sites in Europe and the United States, surpassing its own 3 GW target ahead of schedule. Management expects to exceed 4 GW by year-end 2026. Utility interconnection queues in most Western markets stretch years into the future. Nebius got there first.
What makes this power portfolio structurally defensive is that Nebius designs and builds its own servers in-house. Unlike CoreWeave or Lambda, which source from Dell, HPE, or Supermicro, Nebius controls every layer of the hardware stack. The company's engineering DNA traces back to Yandex, where founder Arkady Volozh built some of the most sophisticated data center infrastructure outside the United States. That in-house capability translates to optimized power-to-compute ratios, shorter lead times, and lower unit costs at scale.
The customer roster reflects this technical credibility. Meta and Microsoft are live customers alongside a growing roster of AI-native model builders and enterprise SaaS platforms. Nebius's AI Token Factory product, providing inference-as-a-service for production workloads, grew 3.5x quarter-over-quarter in Q1 2026. The company's ARR guidance of $7 to $9 billion for FY2026 implies the revenue acceleration is far from peaking.
Financially, Nebius holds roughly $9.3 billion in cash and plans $20 to $25 billion in capital expenditures this year. That spending power, combined with the NVIDIA partnership, lets Nebius lock in power contracts, real estate, and silicon commitments years ahead of competition. The AI cloud segment's adjusted EBITDA margin nearly doubled sequentially to 45%, suggesting scale is beginning to flow through to the bottom line even as investment intensity remains extreme.
For Europe, the stakes extend beyond quarterly earnings. The EU has watched its digital economy grow increasingly dependent on US cloud infrastructure. Sovereign AI — the ability to train and run frontier models on European soil under European data governance — has become a policy priority from Brussels to Berlin. Nebius, headquartered in Amsterdam with data centers across Finland, France, and the Netherlands, is the only company positioned to fill that gap at hyperscale. European workloads running on Nebius do not route through US-controlled infrastructure, a consideration fast becoming a procurement requirement for government agencies and regulated industries.
Risks remain. The Yandex lineage carries geopolitical overhang. Execution risk on a $20 billion capex program is non-trivial. And while the 45% EBITDA margin is encouraging, it comes at a moment when capital spending consumes virtually all operating cash flow. A rotation away from AI infrastructure would hit Nebius's multiple disproportionately hard.
But the structural thesis is compelling precisely because it is hard to replicate. Building a European AI cloud from scratch would require years of power negotiations, silicon partnerships, and regulatory navigation. Nebius has already done all three, layering on NVIDIA-backed GPU access, proprietary hardware design, locked-in power capacity, and European domicile. For investors who believe the AI infrastructure cycle has years left to run — and that Europe will not outsource its sovereignty a second time — Nebius is the only pure-play vehicle capturing both the growth and the geopolitical thematic in a single ticket.
