SoftBank to pour €45bn into French AI data centres

TL;DR:

  • SoftBank will invest €45bn (about £38bn) over five years to build AI infrastructure in France’s Hauts-de-France region, delivering 3.1 GW of capacity.
  • The Japanese group describes it as the biggest investment of its kind in Europe, with further sites pushing the total commitment to €75bn (about £63bn).
  • Founder Masayoshi Son cited France’s status as an energy producer and exporter as “absolutely decisive” — a pointed reminder that compute follows cheap, reliable power.

Announced ahead of France’s Choose France business summit, the plan involves three initial sites, including one in Dunkirk, due to come online by 2031. Schneider Electric will supply modular equipment, and state-owned nuclear giant EDF is handing over a former power plant to be converted into a data centre.

What it means for the UK

The deal sharpens a competitive question for Britain. SoftBank’s logic — abundant low-carbon nuclear power, available land and government courtship — describes advantages France can press harder than most. For the UK, which has touted AI infrastructure ambitions but faces grid-connection delays and higher industrial energy costs, a €75bn neighbour-state commitment is a benchmark that is difficult to ignore.

The investment also reflects SoftBank’s broader AI spree, which includes more than $30bn put into OpenAI for roughly an 11% stake. Concentrating that capital in continental Europe, rather than the UK, underscores how infrastructure decisions increasingly hinge on energy strategy as much as talent or capital. The contrast matters because data-centre siting shapes where downstream AI jobs, services and supply chains ultimately cluster.

Looking forward

Formal confirmation was due at Choose France, but the strategic signal is already clear: Europe’s AI build-out is accelerating, and energy policy is the decisive variable. UK policymakers weighing how to attract similar commitments will note that SoftBank’s choice rewarded a country that could promise power first. Whether Britain can offer a comparable proposition — and quickly — will help determine its place in the European compute map.
