SoftBank pledges €75B to build Europe’s largest AI facility in France

SoftBank is in discussions with French President Emmanuel Macron over what would be the largest AI data center project ever built on European soil. The potential investment could reach up to $100 billion, positioning France as the continent’s premier hub for artificial intelligence infrastructure.

The talks originated from a recent meeting in Tokyo between SoftBank founder Masayoshi Son and Macron. An announcement could coincide with the Choose France Summit, Macron’s signature event for courting foreign investment into the country.

Son’s global AI infrastructure blitz

SoftBank recently reported a net profit exceeding $30 billion, roughly quadrupling its previous results, driven largely by AI-related investments and stakes in entities like OpenAI.

Back in March 2026, SoftBank revealed a significant AI data center initiative in Ohio with reports suggesting costs could climb as high as $500 billion.

The final investment amount may vary depending on evolving project parameters and priorities, so the headline number should be treated as a ceiling rather than a firm commitment.

Why France, and why now

Macron has spent years positioning France as Europe’s answer to Silicon Valley. The country has produced notable AI companies, including Mistral AI, which has emerged as a credible alternative to US-based large language model developers.

For Macron, the timing is strategic. The Choose France Summit has become his preferred stage for announcing splashy foreign investment deals, and landing a commitment from one of the world’s most prominent tech investors would reinforce the narrative that France is open for business.

What this means for investors

There’s a real risk worth flagging. SoftBank has a well-documented history of making enormous commitments that don’t always materialize as initially described. The fact that the investment amount may still shift depending on priorities suggests this deal is far from finalized.

The Choose France Summit will be the next key catalyst to watch. If Son appears alongside Macron with a formal commitment and specific details around capacity, timeline, and energy sourcing, the market will treat this as a serious infrastructure play.
