SoftBank Commits €75 Billion to Build 5 GW of AI Data Centers in France

By Hector Herrera | June 1, 2026 | Business

SoftBank Group has pledged up to €75 billion to build and operate 5 gigawatts of AI data center capacity in France—the largest AI infrastructure commitment by a single company in European history. The deal, brokered directly between SoftBank founder Masayoshi Son and French President Emmanuel Macron, positions France as the anchor market for SoftBank's European AI expansion and signals that the global race to build AI compute is now firmly global.

For Europe, which has watched the United States and China dominate AI infrastructure investment for years, this is a significant inflection point. For SoftBank, it is a bet that European AI demand is real enough to justify building before tenants are fully signed.

The Deal Structure

According to Euronews, the commitment breaks into two phases:

• Phase 1: Three data centers in the Hauts-de-France region, delivering 3.1 gigawatts of compute capacity by 2031. Initial capital outlay: €45 billion.
• Full buildout: A total of 5 gigawatts across France at full completion, with total investment reaching €75 billion.

For scale: 5 GW is roughly the equivalent of five of the largest data center campuses currently operating in the United States. A single large hyperscale data center typically runs between 100 and 300 megawatts.

The Hauts-de-France region—in the north of the country near Belgium—was likely selected in part for access to electrical grid infrastructure and land availability. France's grid is predominantly nuclear-powered, which makes it one of the lowest-carbon electricity sources in Europe, a meaningful factor as AI compute faces mounting scrutiny over energy consumption.

How This Deal Happened

The announcement was brokered through direct head-of-state diplomacy. Masayoshi Son met personally with President Macron, continuing a pattern Son has used before—he made a similar direct pledge to U.S. President-elect Donald Trump in late 2024, committing $100 billion to U.S. AI investment. France's willingness to engage SoftBank at the presidential level reflects how aggressively European governments are competing to capture AI infrastructure investment before it concentrates elsewhere.

SoftBank is not primarily an AI compute operator—it is an investment conglomerate best known for its Vision Fund, which holds stakes in companies including Arm Holdings. This deal suggests SoftBank is making a direct infrastructure play, either to operate the capacity itself or to anchor a new AI infrastructure vehicle, a model similar to what it has explored with the Stargate initiative in the United States.

What This Means

For France: The announcement creates high-skilled construction and operations jobs and establishes the country as Europe's leading AI infrastructure hub, ahead of Germany and the UK. The French government has been actively courting AI investment since the European AI Act passed in 2024.

For European AI development: European AI companies and research institutions currently face a significant capacity gap—most frontier AI compute sits in U.S.-operated hyperscale facilities. A 5 GW French buildout could meaningfully shift where European AI workloads run and who controls that infrastructure.

For SoftBank: This is a major capital deployment at a time when SoftBank is rebuilding from Vision Fund losses. The bet only pays if European AI adoption—enterprise AI, sovereign AI, research compute—continues to grow at the pace analysts currently project.

For the broader market: SoftBank joins Microsoft, Google, Meta, and Amazon in making multi-year, multi-billion AI infrastructure commitments. The aggregate capital flowing into AI compute globally now runs into the trillions of dollars over five-year horizons, raising legitimate questions about whether demand will materialize fast enough to service the debt these projects carry.

What to Watch

The first concrete signal will be whether SoftBank announces anchor tenants—AI companies or government entities that will consume the compute—before or concurrent with breaking ground. A €45 billion Phase 1 commitment without committed customers is aggressive. Watch also for whether the French government offers tax incentives, permitting fast-tracks, or energy rate agreements that would de-risk the investment. Those terms, when disclosed, will reveal how much of the €75 billion headline is genuine private capital versus a publicly subsidized development.
