SoftBank to invest €75 billion in France AI data centers

France is set to gain a vast new slab of AI infrastructure, and with it a sharper test of whether Europe can control the compute that increasingly powers its economy. SoftBank Group Corp. said it will invest as much as €75 billion to develop and operate 5 gigawatts of AI data center capacity in France, with an initial €45 billion phase planned for 3.1 gigawatts in Hauts-de-France by 2031.

The first wave of the project points north, where some reports placed sites in Dunkirk, Loon-Plage, Bosquel and Bouchain. Masayoshi Son has described the buildout as the biggest AI infrastructure investment in Europe so far, a scale that would put France at the center of the continent’s fight over cloud capacity, power supply and strategic control over digital infrastructure.

The timing was inseparable from Emmanuel Macron’s Choose France summit, which was designed to showcase factories, data centers, laboratories, jobs and new industrial projects across French regions. For Paris, the appeal is obvious: a foreign backer willing to finance power-hungry infrastructure at a moment when France wants to present itself as a European AI hub built on low-carbon electricity and a large nuclear fleet.

That promise comes with a harder reckoning. France’s environmental agency ADEME says the country already has 352 active data centers that consume 10 terawatt-hours of electricity each year. Adding another 5 gigawatts of AI capacity would intensify the pressure on grids, permits and water systems, even as local officials weigh the prospect of construction jobs, long-term operations work and a stronger industrial base in Hauts-de-France.

The investment also raises a larger policy question for Europe. The continent has spent years trying to reduce dependence on foreign cloud and compute providers, arguing that artificial intelligence should not be built entirely on infrastructure controlled elsewhere. A SoftBank commitment of this size would bring capital and speed, but it would also deepen the debate over whether Europe is building sovereign capacity or simply hosting it. France may emerge as one of the region’s leading AI infrastructure centers, but the real measure of success will be whether that capacity strengthens European control rather than outsourcing it.
