OpenAI pauses Stargate UK

OpenAI has put its main United Kingdom data-centre plan on pause, even though the company spent months presenting Britain as a place to build local artificial intelligence computing power. The company told reporters it would move ahead only when energy prices and regulation support “long-term infrastructure investment.” (reuters.com) The paused project was called Stargate UK, and it was announced in September 2025 with Nvidia and Nscale. The plan was to lease up to 8,000 Nvidia graphics processing units at first and eventually scale to 31,000 across several British sites, including Cobalt Park in North Tyneside. (nscale.com) A data centre for artificial intelligence is basically a warehouse full of chips that turn electricity into answers, images, and software code. If the electricity bill is wrong, the whole business model bends out of shape before a single server rack is switched on. (cnbc.com) OpenAI’s complaint was blunt: industrial power in Britain is far more expensive than in the United States. Reporting on the pause said UK industrial electricity prices were about four times higher than in the US, which is the kind of gap that can decide where a multibillion-pound facility gets built. (thenextweb.com) The second problem was copyright law, not concrete or cables. The UK government said on March 18, 2026 that the application of British copyright law to training artificial intelligence models is still disputed, and that it is trying to design a framework that gives creators payment and developers legal certainty. (gov.uk) That uncertainty matters because model training depends on huge libraries of text, images, audio, and video, and every disputed source can become a lawsuit or a licensing bill. A government consultation published in December 2024 said the goal was to balance “strong protections” for creative industries with an “internationally competitive” regime for artificial intelligence training. (gov.uk) Britain had pitched the project as part of a bigger push to become an artificial intelligence hub, with “AI Growth Zones” meant to speed up power access and planning. Stargate UK was supposed to help create what supporters called sovereign compute, meaning British-based chip capacity for public services, finance, and security work that governments and regulated industries do not want running entirely overseas. (eandt.theiet.org) The pause also shows how different the UK build was from the giant United States version of Stargate. Coverage of the British plan described it as much smaller than the US project, which had been framed around hundreds of billions of dollars in infrastructure spending over four years. (sharewatch.com) OpenAI has not killed the UK plan outright, and it says it will keep working with the British government on public-service uses of ChatGPT and other tools. But for now, the country that wanted local artificial intelligence capacity has run into two old-fashioned bottlenecks: the price of power and the price of permission. (bloomberg.com)
