SoftBank has announced plans to invest up to €75 billion in the construction of data centres across France, marking what analysts are describing as the largest single AI infrastructure commitment ever made on European soil. According to TechCrunch AI, the Japanese investment conglomerate’s goal is to develop and operate up to five gigawatts of additional data centre capacity, enough to power some of the most demanding artificial intelligence workloads at continental scale.
The announcement, made on 30 May 2026, sent ripples through European technology markets and has immediate implications for the United Kingdom, which is engaged in its own race to secure data centre investment and AI infrastructure capacity ahead of anticipated regulatory frameworks set to take effect later this decade.
The Scale of the Commitment
According to TechCrunch AI, the €75 billion figure represents an upper ceiling on SoftBank’s planned outlay, with spending expected to be phased across multiple years as construction and grid connections are established. The five-gigawatt capacity target would place France among the most data centre-dense nations in the world, rivalling established hubs in Ireland, the Netherlands, and, notably, the United Kingdom.
For context, the entirety of the UK’s current operational data centre capacity is estimated at approximately three to four gigawatts, according to industry body techUK. SoftBank’s planned French deployment would, if fully realised, exceed the UK’s entire existing estate in a single programme.
Why France, and What It Means for Britain
France has aggressively courted hyperscale investment following President Macron’s initiative to position the country as Europe’s leading AI nation, including the announcement of a dedicated AI action plan earlier in 2026. Its access to abundant, relatively low-carbon nuclear electricity has made it an attractive destination for energy-intensive AI compute facilities.
The UK Government has itself set ambitious targets for data centre expansion under its AI Opportunities Action Plan, published in January 2025, which identified data centre infrastructure as a strategic national priority. However, critics have warned that grid connection delays and planning bottlenecks continue to hamper the UK’s ability to compete for flagship investments of this magnitude.
According to analysis published by property consultancy Knight Frank, the UK remained Europe’s largest data centre market by installed capacity as recently as late 2025, but that position is increasingly contested. SoftBank’s decision to place its marquee European bet in France rather than the UK is likely to intensify pressure on the Government and the National Grid to accelerate reforms.
SoftBank’s Broader AI Strategy
The French announcement forms part of SoftBank’s wider pivot towards AI infrastructure under founder and chief executive Masayoshi Son. According to TechCrunch AI, SoftBank has been actively seeking to deploy capital at scale into compute infrastructure following its investment in OpenAI’s Stargate project in the United States earlier in 2025.
The company has previously expressed interest in UK technology assets and was involved in discussions around domestic AI investment during 2025. Whether the French commitment displaces or supplements any potential UK activity remains unclear, and SoftBank had not responded to requests for comment at the time of publication.
Industry Reaction
Technology trade groups in London reacted swiftly to the news. According to statements shared with AI News Today, representatives from techUK called on the Department for Science, Innovation and Technology to convene an emergency review of grid connection timelines and planning permissions for data centre applications. The organisation has long argued that the UK risks ceding its data infrastructure leadership to continental rivals if structural barriers are not addressed as a matter of urgency.
The announcement also raised questions about data sovereignty and the implications for UK businesses that may ultimately rely on French-based compute capacity to run AI services, particularly given the post-Brexit complexity of cross-border data flows under the UK GDPR framework. Those questions are expected to become more pressing as the investment progresses from announcement to construction.
