Shares of SoftBank Group surged 14% during Monday’s trading session following CEO Masayoshi Son’s revelation of a €75 billion ($87 billion) artificial intelligence data center initiative in France, representing the Japanese conglomerate’s most significant European infrastructure pledge.
The equity has now appreciated over 70% throughout 2026, fueled by market enthusiasm surrounding SoftBank’s strategic positioning in the AI sector via its holdings in Arm Holdings and OpenAI.
Son unveiled the investment plan at France’s Choose France economic summit, appearing alongside President Emmanuel Macron. When accounting for the comprehensive system infrastructure, Son indicated the total commitment approaches $750 billion.
The opening phase encompasses $53 billion dedicated to establishing 3.1 GW of AI-focused data center capacity throughout the Hauts-de-France area — particularly in Dunkirk, Bosquel, and Bouchain — with a 2031 deadline.
SoftBank intends to collaborate with its subsidiary SB Energy and join forces with French industrial engineering company Schneider Electric to create a massive industrial manufacturing complex in Dunkirk. The complete initiative aims for 5 GW of total capacity nationwide.
The Strategic Rationale Behind France
Son highlighted France’s electrical grid capabilities, available industrial properties, and skilled engineering workforce as primary factors driving the location decision. The country’s power network — predominantly nuclear-based — provides reduced carbon emissions and more predictable energy expenses relative to neighboring European nations.
Roland Lescure, France’s economy and digital sovereignty minister, characterized it as evidence of France’s “fast access to the most reliable electrical grid in Europe.” EDF chairman Bernard Fontana noted the initiative would transform former industrial locations while advancing France’s digital infrastructure ambitions.
This consideration carries significant weight because energy expenditures have emerged as among the most substantial obstacles to AI data center expansion throughout Europe. Escalating electricity costs — partially linked to geopolitical tensions including the U.S.-Iran situation — have complicated large-scale computing infrastructure investments across the region.
SoftBank’s Artificial Intelligence Portfolio
SoftBank’s French commitment extends its comprehensive AI infrastructure strategy, which is currently advancing in the United States.
The corporation has allocated over $30 billion toward OpenAI, recording $45 billion in investment appreciation from that holding during the fiscal year concluding in March. Its ownership position in Arm Holdings, whose semiconductor architectures enable Nvidia-powered AI servers, maintains its strong connection to the foundational infrastructure supporting the AI expansion.
SoftBank indicated the French data centers will accommodate AI enterprises, cloud service providers, corporate clients, governmental agencies, and academic research institutions. The company additionally intends to collaborate with regional universities and technical colleges to facilitate talent development.
SoftBank surpassed Toyota to claim the position of Japan’s highest-valued corporation by market capitalization earlier in the current year, based on FactSet information.
The Choose France summit functions as a platform for securing international capital, and this week’s declarations have attracted pledges from approximately 100 corporations, according to statements from the French presidential office.
