SoftBank partners with Sesterce on 75‑billion‑euro AI...
Seventy-five billion euros is not a bet. It’s a declaration, and SoftBank is building its fortress on a decommissioned military site in Bosquel, France. Their local partner is a little-known French startup named Sesterce.
This planned “AI factory” fuses raw power—energy, compute—with palpable political ambition. It’s one staggering bid for European sovereignty.
The first phase calls for 45 billion euros in data centers with 3.1 gigawatts of capacity in the Hauts-de-France region by 2031, spread across sites in Dunkirk, Bosquel, and Bouchain. It's SoftBank's largest AI infrastructure investment in Europe, announced at President Macron's Choose France summit.
Skepticism is warranted. Look at SoftBank’s global ledger: a proposed $100 billion “Stargate” venture in Abu Dhabi with G42, a trillion-parameter model project with Japan’s NEC and Sony. Many are just announcements.
The gap between promise and ground-breaking is a canyon. Yet the Bosquel project feels different. It’s specific.
It’s in France. It ties compute to a local energy source and partners with Sesterce, not just an American blueprint. That local embeddedness is its best chance.
If it works, Mistral’s algorithms get a sovereign home. Europe gets an anchor. The need is acute.
Now, SoftBank must pour concrete. The spade is in the ground. Pouring seventy-five billion euros worth will be the hard part.

Common Questions Answered
Why is SoftBank building an AI factory at a decommissioned military site in Bosquel, France?
SoftBank is leveraging the Bosquel location to establish European AI sovereignty and infrastructure independence. The decommissioned military site provides the necessary space and local energy resources to power a massive 75-billion-euro AI computing facility, while partnering with French startup Sesterce demonstrates commitment to local embeddedness rather than relying solely on American blueprints.
What role does Sesterce play in SoftBank's Bosquel AI factory project?
Sesterce, a little-known French startup, serves as SoftBank's local partner for the Bosquel AI factory initiative. This partnership is significant because it ties the massive compute infrastructure to a local French entity, which analysts suggest gives the project a better chance of success compared to SoftBank's other international AI ventures that lack this local embeddedness.
How does the Bosquel project differ from SoftBank's other AI initiatives like Stargate and the trillion-parameter model project?
Unlike SoftBank's proposed $100 billion Stargate venture in Abu Dhabi with G42 or its trillion-parameter model project with Japan's NEC and Sony, the Bosquel project is more specific and concrete rather than just an announcement. The Bosquel project's local partnership with Sesterce, integration with a dedicated French energy source, and physical location in France make it feel more substantive and less likely to remain unfulfilled compared to SoftBank's other global AI proposals.
What does the 75-billion-euro investment in the Bosquel AI factory represent politically?
The massive 75-billion-euro investment represents a significant political statement about European AI sovereignty and independence from American AI dominance. By establishing this "AI factory" with dedicated compute power and energy resources in France through a local partnership, SoftBank is making a declaration of commitment to European technological autonomy rather than simply importing American AI infrastructure.
