Nscale, BT Plan UK Sovereign AI Data Centers With NVIDIA Stack
UK telecom giant BT Group is teaming up with AI infrastructure developer Nscale to roll out sovereign AI data centers across the U.K., marking the latest push to localize compute capacity amid rising demand for AI and tighter data governance requirements.
The partnership, announced Thursday, will see Nscale deploy up to 14 megawatts of AI data center capacity across three existing BT sites, with BT Group providing connectivity and core infrastructure. The facilities will run on full-stack systems from NVIDIA, reflecting the growing role of vertically integrated hardware and networking stacks in next-generation AI deployments.
The buildout is positioned as part of a broader “sovereign AI” strategy—keeping compute, data, and model operations within national borders. That theme has gained traction across Europe as governments and enterprises seek to balance AI adoption with regulatory compliance, particularly around data residency and security.
Under the arrangement, BT will extend its enterprise platform to offer AI services that allow customers to run workloads domestically, scale compute without upfront capital investment, and meet regulatory requirements tied to sensitive data in sectors such as healthcare, finance, and public services.
The announcement also aligns with the U.K. government’s AI Opportunities Action Plan, which calls for expanded domestic infrastructure to support economic growth and reduce reliance on foreign-controlled compute. BT, Nscale, and NVIDIA are founding members of a newly formed industry group aimed at advancing sovereign AI capabilities in the country.
The planned capacity—while modest relative to hyperscale campuses measured in hundreds of megawatts—shows a different deployment model centered on modular, distributed infrastructure tied closely to telecom networks.
The BT partnership comes amid a series of moves by Nscale to position itself as a modular AI data center developer leveraging NVIDIA’s ecosystem. The company has focused on deploying smaller, rapidly scalable facilities rather than pursuing large, capital-intensive hyperscale builds. Nscale raised $2 billion in a Series C funding round earlier this year with a valuation of $14.6 billion.
