SoftBank Commits EUR 75 Billion to Build Europe's Largest AI Data Centers in France

SoftBank Group announced at the 2026 Choose France summit a commitment to invest up to 75 billion euros in artificial intelligence data center capacity across France -- the largest single AI infrastructure investment in European history. The announcement, made before French President Emmanuel Macron, comes at a moment when European governments are actively competing to attract the massive capital flows associated with AI infrastructure buildout.

The Structure of the Commitment

The 75 billion euro figure breaks into two distinct tranches. The firm commitment is 45 billion euros, earmarked to develop 3.1 gigawatts of AI data center capacity at three sites in the Hauts-de-France region: Dunkirk (Loon-Plage), Bosquel, and Bouchain, targeting completion by 2031. The remaining 30 billion euros is conditional, covering plans for an additional 1.9 gigawatts of capacity at other French sites -- contingent on regulatory approvals, grid access agreements, and market conditions.

Combined, the investment would create 5 gigawatts of AI compute capacity across France. The total installed data center capacity in France today is estimated at around 1.5 to 2 gigawatts. This single commitment would more than triple it.

Why France

SoftBank and its partners specifically cited France's low-carbon electricity grid, predominantly nuclear-powered, as a decisive factor. AI data centers are extraordinarily power-intensive -- at gigawatt scale, the source and stability of electricity supply becomes a strategic consideration. France's nuclear fleet provides both low-carbon credentials and reliable baseload capacity that is difficult to match with renewable-only grids in other European countries. The Hauts-de-France region also offers industrial infrastructure, port access at Dunkirk, and proximity to subsea cable landing points connecting to the UK and beyond.

Key Partners and What They Build

Three major partners are embedded in the project. SB Energy, SoftBank's energy subsidiary, will handle power procurement and energy infrastructure. EDF, the French state electricity utility, is involved in the power supply agreements -- effectively making the French government a structural stakeholder in the project's success. Schneider Electric is co-developing a robotized manufacturing cluster at the Port of Dunkirk to produce data center components and power modules, creating a local European supply chain for AI infrastructure. This aligns with broader European industrial policy goals around technology sovereignty.

The Bigger Picture: Europe's AI Infrastructure Race

The SoftBank announcement is part of a broader pattern of large-scale AI infrastructure investment commitments in Europe in 2025 and 2026. Microsoft, Google, Meta, and Amazon have all announced multi-billion-euro European data center expansions. The Choose France summit has become a recurring venue for these announcements -- a deliberate policy by the Macron government to position France as the preferred European destination for AI capital.

The strategic question is whether commitments of this scale translate into operational capacity on the announced timelines. Data center construction at gigawatt scale faces genuine constraints: lead times for high-voltage electrical transformers are currently measured in years, not months; planning and permitting processes in European jurisdictions can be slow; and competition for the same skilled trades workers across multiple simultaneous large-scale projects creates supply chain pressure. SoftBank's 2031 completion target for the first phase is ambitious but not implausible if the firm commitment phase proceeds without major delays.
