Introducing Stargate UK

We’re announcing Stargate UK—an AI infrastructure partnership with NVIDIA and Nscale that strengthens the UK’s sovereign compute capabilities. Stargate UK ensures OpenAI’s world-leading AI models can run on local computing power in the UK, for the UK—particularly for specialist use cases where jurisdiction matters. This will help power the UK’s future economy, boost its global competitiveness and deliver on the country’s national AI Opportunities Action Plan.

The initiative marks a major step forward in the US-UK technology partnership and is the latest rollout of OpenAI for Countries to support governments that want to build out their sovereign AI capabilities. It follows the MoU we signed with the UK Government in July 2025 to explore the UK’s infrastructure priorities and accelerate the adoption of AI.

Nscale is set to significantly expand its planned UK capacity for Stargate UK and the project is expected to be based across a number of sites, including Cobalt Park, which will form part of the newly designated AI Growth Zone in the North East.

OpenAI will explore offtake up to 8,000 GPUs in Q1 2026 with the potential to scale to 31,000 GPUs over time. This sovereign capacity will enable OpenAI’s models to run on local computing power for specialist use cases such as critical public services, regulated industries like finance, research projects or national security partnerships.

NVIDIA will provide access to its most advanced GPUs, ensuring that Stargate UK benefits from the latest generation of AI hardware. Semiconductor designs by leading British chip design company Arm form part of Nvidia’s latest Grace Blackwell series of chips, demonstrating further collaboration between UK and US companies.
