SoftBank has announced a monumental €75 billion investment to build 5 gigawatts of AI data-center capacity in France.
This move is fundamentally about securing immense, reliable, and low-carbon power. AI models require a staggering amount of electricity to train and operate, and finding a stable energy source is the biggest challenge. France offers a unique solution with its powerful nuclear energy infrastructure. This provides a consistent, low-carbon baseload power that is perfect for data centers that run 24/7. This contrasts sharply with SoftBank's other major project in Ohio, USA, which relies on newly built natural gas plants. By choosing France, SoftBank not only secures the energy it needs but also aligns with Europe's decarbonization goals.
But power is only half the story; the other crucial factor is regulation. The European Union's AI Act is set to become fully applicable in August 2026. This landmark regulation creates strict rules for AI systems, and a key part of it involves data sovereignty—the idea that data should be stored and processed under EU jurisdiction. By building massive data centers directly in France, SoftBank can offer its clients 'sovereign-compliant' AI services, which is becoming a major competitive advantage in the European market.
Finally, this investment fits perfectly into SoftBank's larger global strategy. The company, which owns a majority stake in the chip designer Arm, is pivoting to become a dominant force in AI infrastructure. First, they announced the US project, pairing compute with gas power. Now, they are replicating that 'power-with-compute' model in Europe, but with a cleaner energy source. This strategic diversification across geographies and power sources helps them manage risks while building a global AI empire. The soaring market value of Arm provides SoftBank with the financial firepower to undertake such capital-intensive projects.
- Gigawatt (GW): A unit of power equal to one billion watts. 5 GW is an enormous amount, capable of powering millions of homes, and highlights the massive energy scale required for modern AI.
- EU AI Act: The European Union's comprehensive regulation on artificial intelligence. It aims to ensure that AI systems used in the EU are safe, transparent, and respect fundamental rights, creating a pull for data processing to occur within the EU.
- Data Sovereignty: The concept that data is subject to the laws and governance structures within the nation or region where it is collected and processed. This is a key principle behind regulations like the EU AI Act.
