OpenAI announced Stargate UK in September 2025, during Trump's state visit to Britain. Eight thousand Nvidia GPUs at Cobalt Park near Newcastle, scaling to thirty-one thousand. Sovereign compute for public services. A British GPU cloud company called Nscale as local partner. George Osborne hired to oversee the expansion. Construction was supposed to start in Q1 2026.

The deadline passed. Nothing happened. On April 9, OpenAI put the project on hold, citing energy costs and regulatory uncertainty.

The energy numbers are brutal. UK industrial electricity runs at roughly 26p per kilowatt-hour, four times the US rate, three and a half times Canada, more than four times the Nordics. Almost a third of the wholesale price is carbon costs. Green energy subsidies add twelve billion a year on top. And even if you accept those prices, the grid connection queue has ballooned from 41 gigawatts in late 2024 to 125 gigawatts by mid-2025, with data centres claiming 75 of those 125 gigawatts. You can build a facility in under two years. Plugging it in takes three to eight.

Then there's copyright. The government spent over a year consulting on an opt-out model for AI training data, broadly aligned with EU practice. Creative industries rejected it. Elton John and Dua Lipa weighed in. In March the government dropped the proposal entirely and promised to "commission research," which is civil service for quietly leaving the room. The UK now has no copyright framework for AI training. Not permissive, not restrictive. Just absent.

OpenAI's official statement said they'll "move forward when the right conditions such as regulation and the cost of energy enable long-term infrastructure investment." That's not a pause. That's a list of things the UK government cannot fix quickly.

None of this happened in isolation. OpenAI is trimming anything that doesn't point directly at a Q4 2026 IPO. Sora is dead. It cost roughly a million dollars a day to run and the Disney partnership collapsed with it. Instant Checkout with Walmart, gone. Adult Mode, shelved. CFO Sarah Friar has flagged concerns about aggressive spending. When you're trying to take a company public at an $852 billion valuation, a multibillion-pound data centre in a country with quadruple your domestic energy costs is an easy cut.

The UK government called the decision "disappointing." An opposition MP called it a "wake-up call." Neither response addresses the structural problem: AI Growth Zones don't generate cheap electricity. Streamlined planning doesn't move the grid connection queue. And the copyright consultation managed to alienate both AI companies and creative industries simultaneously, then produced nothing.

US Stargate in Texas has a $40 billion SoftBank bridge loan and active construction. Britain got the press conference. Texas got the concrete.
