SoftBank Group announced plans to invest up to €75 billion ($87 billion) to build 5 gigawatts of AI data center capacity across France. The Japanese conglomerate is leveraging France's nuclear-powered electricity grid to bypass the energy challenges plaguing U.S. data center projects, marking its biggest AI infrastructure investment in Europe.

SoftBank Group Investment in France Reaches €75 Billion

SoftBank Group has committed up to €75 billion ($87 billion) to expand AI data centers across France, marking the company's largest AI infrastructure investment in Europe to date

1

. The ambitious plan targets building 5 gigawatts of data center capacity, with CEO Masayoshi Son and President Emmanuel Macron set to formalize the agreement at the Choose France Summit

5

. The first phase involves a €45 billion ($52 billion) commitment to deliver 3.1 gigawatts across three sites in the Hauts-de-France region by 2031: Dunkirk (Loon-Plage), Bosquel, and Bouchain

2

. French economic minister Roland Lescure described the announcement as a testament to positioning France as a leading destination along the AI value chain .

The investment represents one of the largest single infrastructure commitments any country has received for AI, though it falls slightly short of the $100 billion figure Son reportedly floated during initial discussions

5

. Only the €45 billion first phase and its 3.1 gigawatts constitute firm commitments, with additional sites described as plans for later stages

France's Nuclear-Powered Electricity Grid Proves Decisive

What distinguishes this France investment from SoftBank's other global projects is access to reliable, low-carbon energy. France draws roughly 70% of its power from nuclear reactors operated by state-owned utility EDF, making it the world's largest net electricity exporter with industrial power prices well under half the UK's

2

. Son told La Tribune du Dimanche that France being a producer and exporter of energy was "absolutely decisive" for investments in AI infrastructure

This stands in stark contrast to SoftBank's American plans. To power its planned 10-gigawatt data center in Ohio, the company must build its own energy generation infrastructure—a natural gas plant costing roughly $33 billion to generate approximately 9.2 gigawatts

2

. France allows SoftBank to skip that step entirely and plug into an existing low-carbon nuclear power fleet, sidestepping the strained grids and rising local opposition slowing U.S. buildouts

2

. EDF is contributing the Bouchain site, a former power plant, which it will hand over for conversion into French data center capacity

.

Strategic Partnerships Drive Vertical Integration

French engineering company Schneider Electric will serve as a key partner, equipping the sites with its power modules, though financial details were not disclosed

3

. At the Port of Dunkirk, SoftBank and Schneider Electric plan to build an industrial cluster featuring two plants—one operated by SoftBank to manufacture enclosures and one run by Schneider to integrate data center power modules

2

. This vertical integration approach extends SoftBank's existing capabilities across Arm, robotics, and its proprietary water-based data center batteries into prefabricated electrical equipment

2

. The Dunkirk hub is strategically positioned to serve major European capitals including London, Brussels, and Amsterdam

Sovereign AI Policy Meets Personal Diplomacy

The deal reflects both strategic policy alignment and personal diplomacy between Son and Macron. Son told La Tribune he was "very impressed by the fact that Emmanuel Macron is so personally committed to ensuring France's economic success"

5

. Macron approached Son directly during a visit to Japan earlier this year—an unusual move that intrigued Son, who typically fields inquiries from corporate leaders rather than heads of state

5

.

Macron has championed sovereign AI as a policy priority, arguing that countries beyond the U.S. and China must build their own infrastructure to control their data and technology

5

. SoftBank's commitment validates this sovereign AI policy thesis at a scale no European government initiative has matched, dwarfing previous commitments from Microsoft, Google, and Amazon at past Choose France summits

Financing Questions Shadow Ambitious Commitments

The French commitment adds to an extraordinary global AI infrastructure spending spree by SoftBank. The company has invested more than $30 billion in OpenAI for an approximately 11% stake

3

, with some reports indicating the total exceeds $60 billion for roughly 13% ownership

5

. SoftBank is also a partner in the $500 billion Stargate initiative with OpenAI, Oracle, and Abu Dhabi's MGX to build data centers across the U.S.

5

.

The cumulative scale of these commitments raises questions about financing capacity. SoftBank carries over $130 billion in debt and took a $40 billion bridge loan in March to fund its latest OpenAI investment

2

. The company scaled back plans for a $10 billion margin loan backed by its OpenAI stake after facing hesitation from some creditors, with discussions targeting as low as $6 billion

5

. Whether Son can tap enough capital to deliver on all of his AI ambitions simultaneously remains the question investors are watching most closely
