SoftBank’s Son eyes major France AI data center

SoftBank founder Masayoshi Son is discussing a major AI data center project in France with President Emmanuel Macron, with an announcement potentially coming as soon as this month.

The project could involve a multibillion-dollar investment, and Son has raised the possibility of investing up to US$100 billion in France, though the size of the plan may still change.

Macron reportedly proposed the idea during a meeting in Tokyo, and the project could be unveiled at the Choose France Summit, an event created to attract foreign investment.

The discussions follow SoftBank’s March plans for a data center project in Ohio and its separate Stargate AI infrastructure initiative in the US.

🧠 Food for thought

Implications, context, and why it matters.

Macron’s pitch rests on years of state-backed AI spending

Macron’s proposal fits a national plan started in 2018 that has sent more than 3 billion euros (US$3.53 billion) in public money to AI 1.
The spending built shared resources such as the 3IA institutes, later AI clusters, plus the Jean Zay supercomputer. That government-backed system gives French researchers access to high-performance computing 1.
France also benefits from an energy grid that is 90-95% decarbonized through nuclear and hydropower, giving AI data centers steady electricity with lower carbon emissions 2.
That groundwork has helped France become one of Europe’s leading destinations for foreign AI projects. It has drawn research centers from Google, Meta, and Microsoft 1.

SoftBank’s AI plans meet tighter lending standards

The talk of a large French investment comes as SoftBank faces closer financial scrutiny. It cut a planned margin loan, a loan backed by pledged assets, tied to its OpenAI shares from US$10 billion to as low as US$6 billion after lenders raised concerns 3.
Lenders worried about using unlisted OpenAI shares as collateral. Separately, S&P Global Ratings, a credit ratings firm, changed SoftBank’s outlook to negative in March 2026 3.
The situation sets up a test for AI financing. It pits Masayoshi Son’s long-range bet against credit markets that remain wary of high leverage, meaning heavy use of borrowed money 3.
The result will help decide whether large speculative AI infrastructure projects can win traditional financing.
