SoftBank on June 1, 2026 pledged €75 billion to build Europe’s largest AI data center footprint, targeting 5 gigawatts of capacity across three sites in France. The company called it the largest single AI infrastructure commitment in European history — a bet that the continent’s future compute needs will be enormous, and that France is the place to host them.
The Pledge
The plan commits €75 billion to gigawatt-scale AI data centers across three French locations. At 5 gigawatts total, the footprint would rank among the largest AI computing buildouts announced anywhere in the world — capacity roughly comparable to several large power plants running flat-out for machine learning training and inference.
Why France
Europe has few locations with the grid capacity, land, and energy mix for AI-scale data centers, and France’s low-carbon nuclear fleet gives it a rare combination of steady, emissions-free power. That profile matters doubly for hyperscale AI: operators face both cost pressure and regulatory scrutiny over carbon footprints. France has also pushed hard for sovereign AI capacity, framing domestic infrastructure as strategic autonomy, not just a commercial question.
The Strategy
The announcement fits SoftBank’s broader infrastructure playbook. The company has been scaling AI compute investments across the US and Asia, and Europe — France in particular — fills a gap: a region with strong demand for domestic AI capacity but relatively little of it in operation. For SoftBank, the sites also create a landing zone for customers who need EU-based training and inference for data-residency reasons, turning sovereign AI into a commercial service.
What This Means
For Europe, an anchor investment of this scale changes the arithmetic of the AI infrastructure race: the question is no longer whether the continent will have AI factories, but which operators will run them. For SoftBank, the play is straightforward — bet heavily on the compute buildout every AI lab, enterprise, and government will need, and own a large share of the biggest grid in Europe.
