OpenAI, NVIDIA, and Nscale announced Stargate UK, a new AI infrastructure partnership aimed at strengthening Britain’s sovereign compute capabilities. The project ensures that OpenAI’s models can run locally in the UK, providing compute capacity for specialist use cases where jurisdiction matters—such as national security, regulated finance, and public services. The initiative builds on the July 2025 Memorandum of Understanding (MoU) signed with the UK Government and aligns with the national AI Opportunities Action Plan, marking a new milestone in the US-UK technology partnership.
Stargate UK will be distributed across multiple UK sites, with Nscale significantly expanding its planned footprint, including facilities at Cobalt Park in the newly designated AI Growth Zone in the North East. OpenAI expects to secure offtake for 8,000 GPUs in Q1 2026, with potential to scale to 31,000 GPUs over time. NVIDIA will provide its latest Grace Blackwell chips, which integrate designs from UK-based Arm, highlighting collaboration between US and UK semiconductor ecosystems. This investment in sovereign AI compute directly supports the UK’s ambition to boost competitiveness and secure strategic autonomy in advanced technologies.
Alongside infrastructure, OpenAI will launch the OpenAI Academy in the UK, a program designed to enhance AI literacy, help workers adopt AI tools, and support the government’s goal of upskilling 7.5 million people by 2030. By working with local businesses and institutions, the Academy will develop tailored education pathways that promote regional adoption of AI while driving economic growth. This dual focus on compute infrastructure and workforce training reflects OpenAI’s “AI for Countries” strategy to ensure governments can deploy and benefit from advanced AI responsibly and sustainably.

• UK workforce to benefit from new OpenAI Academy focused on AI literacy and adoption
Sam Altman, CEO of OpenAI, said:
“The UK has been a longstanding pioneer of AI, and is now home to world-class researchers, millions of ChatGPT users, and a government that quickly recognized the potential of this technology. Stargate UK builds on this foundation to help accelerate scientific breakthroughs, improve productivity, and drive economic growth. This partnership reflects our shared vision that with the right infrastructure in place, AI can expand opportunity for people and businesses across the UK.”
🌐 Analysis: Stargate UK positions Britain as one of the first countries to secure sovereign-scale OpenAI capacity, a move echoing global trends where governments are prioritizing local AI infrastructure for sovereignty, security, and competitiveness. For NVIDIA, the deal reinforces its central role in sovereign AI projects, while Arm’s presence in the Grace Blackwell platform highlights the UK’s ongoing influence in semiconductor design. Nscale’s expansion cements its role as a hyperscale AI partner in Europe, competing with CoreWeave and other GPU cloud players building sovereign capacity worldwide.
