SoftBank to Build €45B AI Data Centres in France, Europe’s Largest Investment

SoftBank's Major AI Infrastructure Investment in France

PARIS, May 30 (Reuters) - Japan's SoftBank Group will invest €45 billion over the next five years in a push to build up artificial intelligence infrastructure in France, founder Masayoshi Son told the paper La Tribune Dimanche in an interview published on Saturday.

Investment Details and Regional Impact

Son said the investment, described as the biggest of its kind so far in Europe, would be made in the northern Hauts-de-France region. The overall sum SoftBank intends to invest in France will reach €75 billion, Son said. 

Official Announcement and Choose France Conference

The investment plans are due to be formally announced on Monday at the annual Choose France business conference. 

Data Centre Locations and Timeline

According to La Tribune Dimanche, two sites for data centres at Le Bosquel and Dunkirk are expected to come into operation in 2028 and 2031 respectively, providing together more than 5 gigawatts of computing capacity.

Reasons for Choosing France

"The fact that the country is a producer and exporter of energy is absolutely decisive for investments in AI infrastructure," Son said when asked why he picked France. 

SoftBank's Global AI Investment Strategy

The French commitment adds to a global AI infrastructure spending spree by SoftBank. Its investments in AI also include over $30 billion invested in OpenAI ​so far, for about an 11% stake. 

France's Efforts to Attract Foreign Investment

France has been using the Choose France summit to court foreign investors since it was launched by President Emmanuel Macron in 2018.
