OpenAI Pauses UK Stargate Data Centre Project

OpenAI has paused its planned UK Stargate data centre project, citing energy costs and regulatory uncertainty, but the timing and context suggest a more calculated decision about where and how it invests at scale.

What Is Stargate UK?

The Stargate UK project, announced in September 2025, was intended to build large-scale AI data centre capacity in north-east England in partnership with Nvidia and UK cloud provider Nscale. The plan involved deploying around 8,000 GPUs initially, with the potential to scale up to 31,000 over time.
