OpenAI suspended its Stargate AI infrastructure project in the United Kingdom. High energy costs and the current regulatory environment prompted the decision. The company will resume the project when investment conditions improve.

OpenAI remains committed to its UK presence and an existing public services agreement. The Stargate UK initiative launched in September 2025 as a partnership with Nvidia and Nscale.

The project planned to deploy thousands of advanced Nvidia GPUs. This infrastructure aimed to boost the UK’s sovereign AI computing capabilities. The suspension marks a setback for the UK’s goal of becoming a global AI hub.
