Masayoshi Son is making another massive AI bet, and this time France is the target.
The SoftBank founder is in talks with French President Emmanuel Macron about putting up to $100 billion into the country, anchored by a new AI data center project.
If it lands, it would be the biggest single foreign tech investment Europe has ever seen.
Macron pitched Son personally on the idea, asking SoftBank to make France a hub for AI compute - the chip power needed to train AI models.
The two sides have been talking for weeks, with Son possibly unveiling the project at France's Choose France business summit, the country's yearly showcase for foreign investors.
The full investment may not hit the $100 billion ceiling, since SoftBank could trim the France piece if Son decides to put more capital into rival projects elsewhere.
The headline number is still a marker of how far the data center race has come.

Europe has been losing the AI build-out to the US for two years running.
Most of the giant data center deals - the buildings packed with chips that train models like ChatGPT - have gone to states like Texas, Ohio and Arizona, and France wants to change that with cheap, low-carbon nuclear power to offer.
For SoftBank, France adds a European foothold to a portfolio that's leaning hard into AI infrastructure, and the company has already put more than $30 billion into OpenAI for an 11% stake.
It's also in the middle of a $500 billion US data center project called Stargate, run with OpenAI, Oracle and Abu Dhabi's MGX, plus a separate $500 billion Ohio build that was announced earlier this year.
If every announced SoftBank project gets fully funded, the company is committing more capital to AI than the GDP of most countries.
Son has a long history of giant bets that didn't pan out - WeWork being the most famous - but this is different in scale.
The company has bet that whoever owns the data center capacity ends up owning a big share of the AI economy, and every new build is meant to lock in that position.
For investors, the size of these commitments is part of the story, since SoftBank is making AI infrastructure look more like a sovereign-level capital expense than a corporate one.
The Choose France summit is the next checkpoint.
If Son shows up with Macron and a number, the bet becomes real, but if he doesn't, the project goes into the same pile of countless other AI announcements that haven't moved past press releases.
Either way, France's signal is clear - it wants in on the data center race.
