OpenAI pauses UK datacentre, faces probe

OpenAI spent 2025 telling governments that more computing power was the bottleneck in artificial intelligence, then hit pause on a flagship United Kingdom data-centre plan because electricity and permits were too hard to line up. The same week, Florida’s attorney general opened an investigation into OpenAI and ChatGPT as investors watch for a possible stock-market listing. (openai.com) (theguardian.com) (reuters.com) The United Kingdom project was tied to “Stargate,” OpenAI’s infrastructure push with SoftBank and Oracle, which OpenAI launched in January 2025 as a plan to invest $500 billion in artificial-intelligence infrastructure in the United States over four years. By September 2025, OpenAI said Stargate had nearly 7 gigawatts of planned capacity across U.S. sites including Abilene, Texas, New Mexico and Wisconsin. (openai.com 1) (openai.com 2) A data centre for artificial intelligence is basically a warehouse full of chips, cooling gear and power lines, and the hard part is not pouring concrete but getting enough electricity to run it. The United Kingdom government’s own Artificial Intelligence Opportunities Action Plan said power access and slow planning were the two biggest barriers to new data centres. (gov.uk 1) (gov.uk 2) That is why the British government spent 2025 creating “Artificial Intelligence Growth Zones,” which are special areas meant to speed up planning approvals and reserve grid capacity for large computing sites. In November 2025, the government said it was also introducing targeted electricity-cost reductions inside those zones to unblock projects that were stalling on energy prices. (gov.uk) (delivery.ai.gov.uk) OpenAI’s pause lands awkwardly because the United Kingdom had spent months pitching itself as Europe’s place to build this kind of infrastructure. In January 2025, Prime Minister Keir Starmer’s government said private tech firms had already committed £14 billion and 13,250 jobs alongside its artificial-intelligence plan, and by January 2026 it said five growth zones had been designated. (gov.uk 1) (gov.uk 2) The Florida investigation is a different problem, but it points at the same pressure point: OpenAI is no longer just a lab shipping chatbots, and every expansion now drags in regulators, contracts and public-law fights. Reuters reported on April 9, 2026 that Florida attorney general James Uthmeier had opened a probe into OpenAI and ChatGPT ahead of a possible initial public offering, which is the process of selling shares to public investors for the first time. (reuters.com) An initial public offering forces a company to open more of its books, risks and governance to outside scrutiny, so a state investigation arriving before that can become part of the story investors read. Reuters said the probe raised questions about governance and legal risk for customers and partners, which is exactly the kind of issue that can complicate a company trying to look predictable before a listing. (reuters.com) OpenAI has kept pouring money into expansion elsewhere, which makes the United Kingdom pause look less like a retreat from infrastructure and more like a choice about where building is easiest. On March 31, 2026, OpenAI said it had raised $122 billion to accelerate its next phase, after earlier saying Stargate’s U.S. buildout was already ahead of schedule. (openai.com) (openai.com) Put those two headlines together and the picture is simple: OpenAI has cash, demand and political attention, but it still cannot wish away grid queues, planning delays or legal scrutiny. For governments trying to win artificial-intelligence investment, and for companies betting on OpenAI as a supplier, the bottleneck is no longer hype but whether the wires, permits and regulators line up in time.
