Shares of SoftBank Group rallied 14% during Monday’s trading session following CEO Masayoshi Son’s announcement of a massive €75 billion ($87 billion) artificial intelligence data center initiative in France, representing the Japanese conglomerate’s most substantial European infrastructure project ever.
The technology and telecommunications giant has experienced remarkable momentum in 2026, with shares climbing over 70% year-to-date as investors grow increasingly confident in the company’s AI strategy, particularly through its significant holdings in Arm Holdings and OpenAI.
During France’s Choose France investment conference, Son detailed the ambitious project alongside President Emmanuel Macron. When accounting for the complete ecosystem infrastructure, Son suggested the total investment figure approaches $750 billion.
The opening phase encompasses $53 billion dedicated to establishing 3.1 gigawatts of AI-focused data center capacity throughout the Hauts-de-France territory—targeting municipalities including Dunkirk, Bosquel, and Bouchain—with completion targeted for 2031.
SoftBank intends to leverage its SB Energy division while collaborating with French industrial engineering powerhouse Schneider Electric to create an extensive industrial manufacturing hub in Dunkirk. The comprehensive initiative aims for 5 GW of total capacity nationwide.
Strategic Rationale Behind France Selection
Son highlighted France’s robust electrical grid system, available industrial real estate, and skilled engineering workforce as primary factors driving the location decision. France’s power infrastructure—predominantly nuclear-based—provides reduced carbon emissions and more predictable energy expenses relative to neighboring European markets.
Roland Lescure, serving as France’s minister of economy and digital sovereignty, characterized the investment as evidence of France’s “fast access to the most reliable electrical grid in Europe.” EDF chairman Bernard Fontana emphasized the initiative would revitalize previously utilized industrial locations while advancing France’s digital transformation objectives.
This strategic consideration carries substantial weight as energy expenditures have emerged as a critical constraint for AI data center expansion throughout Europe. Escalating electricity rates—partially influenced by U.S.-Iran geopolitical tensions—have complicated large-scale computing infrastructure investments across the region.
SoftBank’s Artificial Intelligence Portfolio
SoftBank’s French commitment extends its ongoing AI infrastructure expansion already progressing in the United States.
The corporation has deployed over $30 billion into OpenAI, generating $45 billion in valuation gains from that position during the fiscal year concluding in March. Its ownership stake in Arm Holdings, whose semiconductor architectures drive Nvidia-powered AI computing systems, maintains its direct connection to foundational AI infrastructure development.
SoftBank indicated the French data center facilities will accommodate AI technology companies, cloud computing platforms, corporate clients, governmental organizations, and academic research institutions. The company additionally outlined intentions to collaborate with regional universities and technical institutes to cultivate talent development.
According to FactSet market data, SoftBank recently surpassed Toyota to claim the position of Japan’s highest-valued corporation by market capitalization earlier this calendar year.
The Choose France conference serves as a platform for attracting international capital, with this year’s event securing investment pledges from approximately 100 corporations, based on statements from the French presidential office.
