OpenAI has announced that the company is pausing its Stargate artificial intelligence (AI) infrastructure project in the United Kingdom (UK). According to a report in Bloomberg, OpenAI has cited the high cost of energy and regulatory environment in the country as the reasons. While maintaining the OPenAI sees huge potential for the UK’s AI future, the company said in a statement “We continue to explore Stargate UK and will move forward when the right conditions such as regulation and the cost of energy enable long-term infrastructure investment,” Politico was first to report that the project was on hold.One of Sam Altman’s most-ambitious projects, OpenAI planned the Stargate project in partnership with Nvidia and Nscale and was set to provide up to 8,000 GPUs. Stargate is primarily OpenAI’s plan to expand global data center capacity to run and train its AI models, starting in the US. Its first campus is in Texas, with similar projects underway in Norway and the United Arab Emirates. The company announced Stargate UK in September, while it has been in talks with the UK government since months before.

High electricity prices and regulations

Industrial energy prices in the UK have been among the highest in the world for years now. Reports claim that critics of British AI infrastructure had previously identified high energy costs and delays in accessing the electricity grid as key obstacles. Other than high energy costs, uncertain copyright regulation too is said to be making OpenAI pause its UK plans. The UK is reportedly currently debating the conditions under which AI models may use copyrighted material. According to a Financial Times report from March, the government is delaying planned changes to copyright law following strong pushback from the creative industries.The announcement to pause the project in the UK comes as OpenAI plans to cut down its spending ahead of the planned IPO. Last month OpenAI also shuttered down its video-generation app Sora. OpenAI also recently scrapped plans to expand its flagship data center campus in Texas with Oracle Corp.

UK Stargate Project

OpenAI announced Stargate UK back in September 2025. Stargate UK would enable the government to run top AI models locally from data centers inside the region, “particularly for specialist use cases where jurisdiction matters.” Analysts see OpenAI’s pullback in the UK as a blow to Prime Minister Keir Starmer’s plan to make Britain a hub for AI development. His ruling Labour party has made data centers a pillar of its economic growth plan. OpenAI’s Stargate project was set to be built in one of the government’s AI Growth Zones, an economic development region. The original Stargate UK project was considered a central pillar of the UK’s AI strategy. It emerged from a memorandum of understanding signed between OpenAI and the British government in July 2025.OpenAI said that it will continue to work with the UK government on an agreement to provide ChatGPT and other services for public services. Politico reported earlier on the pause of its Stargate plan.
