SoftBank Picks France For Major AI Data Center Buildout

Summary:
  • SoftBank plans up to €75 billion in AI data center investment in France, with an initial €45 billion committed over the next five years.
  • The buildout targets 3.1 GW of capacity in the Hauts-de-France region by 2031 and is the largest AI infrastructure investment ever announced in Europe.
  • France's nuclear grid, which generated roughly 67% of the country's electricity in 2024, is a key reason SoftBank chose the country over other European markets.

Most AI money flows to the US. SoftBank just sent a chunk of it to France instead.

The Japanese tech investor is planning a major buildout of AI data centers across the country, a move that says as much about France's power grid as it does about Europe's AI ambitions.

The Bet

SoftBank is one of the biggest AI investors in the world, having already committed hundreds of billions of dollars to AI infrastructure - including the Stargate venture it launched with OpenAI, Oracle, and MGX to build data centers in the US.

Now it's pointing some of that money at France. SoftBank says the commitment could reach €75 billion (about $87 billion), with an initial €45 billion locked in over the next five years to deliver 3.1 GW of capacity in the Hauts-de-France region by 2031 - the largest AI infrastructure investment ever announced in Europe.

For context, Stargate alone carries a $500 billion price tag over four years and stands as one of the largest private infrastructure projects ever announced. The French commitment is a fraction of that - but it's enough to reshape the country's data center map on its own.

Data centers are the picks and shovels of the AI boom. Every chatbot, every image generator, every AI tool you use runs on a server sitting in a building somewhere - and the companies building those buildings are quietly becoming as important as the chip makers.

Why France

France has quietly become one of the most attractive places in the world to build a data center, and the reason is power.

AI data centers use huge amounts of electricity, and France runs most of its grid on nuclear - which keeps power cheap, plentiful, and low-carbon.

Roughly 67% of France's electricity came from nuclear in 2024, the highest share of any major economy. That gives wholesale prices a steady floor most other European grids can't match - exactly what AI companies need to keep costs down and hit climate targets at the same time.

State-owned nuclear giant EDF is part of the SoftBank deal, handing over one of its former power plants to be converted into a data center site, with Schneider Electric signed on as a key equipment partner.

The French government has been pushing hard to bring in AI money. President Macron pitched France as Europe's AI hub at a major summit earlier this year, and big tech players have been signing on ever since.

What to Watch

SoftBank's France move is one more sign that Europe wants a piece of the AI buildout. For years, almost every dollar of AI infrastructure spending has gone to the US, and that's starting to shift.

The real test is whether France can scale its grid fast enough to keep up. Data centers planned today will need power that doesn't exist on the network yet, meaning France will need to bring new nuclear capacity online or expand its existing reactors.

SoftBank is betting France delivers.
