OpenAI's UK Stargate data centre is part of the company's international AI infrastructure expansion, providing sovereign AI training and inference capacity for UK and European markets.
OpenAI's planned UK Stargate data centre represents part of the company's global Stargate initiative to build dedicated AI training and inference infrastructure outside the United States. As part of a broader international expansion covering Norway, the UAE, Australia, South Korea, Argentina, Canada, and India, the UK Stargate deployment reflects OpenAI's strategy to decentralise AI infrastructure and comply with data sovereignty requirements in key markets. The UK represents one of OpenAI's most significant markets and a hub for European AI research and enterprise adoption.
The UK Stargate data centre is expected to be developed in partnership with British infrastructure and technology stakeholders as part of the UK government's broader ambition to secure long-term AI infrastructure investment. OpenAI ended 2025 with approximately 1.9GW of compute capacity globally, with the company's CFO noting that AI compute demand continues to substantially outpace supply. The UK Stargate facility is designed to support the training and inference requirements of OpenAI's frontier models, including GPT-5 series and future generations, as well as providing compute for enterprise ChatGPT deployments serving UK and European customers.
OpenAI's expansion of Stargate beyond the United States marks a significant evolution in the company's infrastructure strategy, driven by the need to meet data residency requirements in regulated markets, reduce latency for international users, and demonstrate commitment to building AI infrastructure with, not just for, key partner countries. The UK facility is expected to leverage British clean energy resources and align with the UK government's ambition to become a leading global AI nation, supporting jobs, skills development, and the broader digital economy.
