Nebius Unveils $10B AI Infrastructure Hub in Finland

**Nebius Group**, the AI-focused infrastructure provider that emerged from the recent restructuring of the Yandex ecosystem, has announced a massive **$10 billion** multi-year investment to build a premiere AI hub in Finland. This initiative positions Nebius as a critical "GPU-as-a-Service" (GPUaaS) alternative for European startups and labs looking for low-latency, sovereign compute capacity.

The Mäntsälä Mega-Fabric

The centerpiece of the investment is the expansion of the existing data center in Mäntsälä, Finland. Nebius plans to deploy over **100,000 high-density GPU nodes**, featuring a mix of Nvidia’s Blackwell (B200) and H200 accelerators. The Finnish site was chosen for its access to low-cost renewable energy and the ability to utilize **district heating**—recycling the heat generated by AI training clusters to provide warmth for local residential communities, a key metric for EU sustainability compliance.

Sovereign GPUaaS

Nebius is targeting the "sovereignty gap" in the European market. As the EU AI Act places stricter requirements on where training data is processed, many European firms are moving away from US-based hyperscalers. Nebius offers a **"pure-play" AI cloud** that is physically and legally restricted to the EU, ensuring that non-EU entities cannot gain access to model weights or underlying data sets. Their stack is optimized for large-scale foundation model training, featuring an Infiniband-native fabric that eliminates networking bottlenecks.

Market Realignment

This $10B move signals that the AI infrastructure war is no longer just about the "Big Three" (AWS, Azure, GCP). Specialized providers like Nebius, CoreWeave, and Lambda are carving out a significant market share by offering **better price-performance** and deeper technical support for AI-specific workloads. Nebius’s S-1 filing (released today) indicates that the company is already approaching a $2 billion revenue run rate, driven primarily by the demand for large-scale inference clusters.

As the "RAMpocalypse" continues to squeeze the global hardware supply, Nebius's guaranteed allocation of high-end silicon represents one of the most valuable resources in the European tech ecosystem.
