UK minister challenges OpenAI over paused flagship AI deal
The UK government has a story about why OpenAI walked away from a flagship AI infrastructure deal. OpenAI has a different story. Last week, OpenAI paused Stargate UK, citing high energy costs and regulatory uncertainty. This week, UK AI Minister Kanishka Narayan went on the record with a direct rebuttal: nothing has changed on either front since the project was announced in September. What changed, he said, was OpenAI's internal financing.
OpenAI declined to comment on the contradiction. Two weeks ago, it announced a $122 billion funding round at a $852 billion post-money valuation — numbers that do not immediately suggest a company short on capital.
The UK is pushing back hard, but its credibility on AI infrastructure is shaky. A Guardian investigation last month found that many UK AI deals described as major investments were phantom projects — including a supercomputer scheduled to go live in 2026 that was still a scaffolding yard in Essex. The government's claim that the AI sector attracted over £100 billion in private investment sits uneasily alongside those findings.
Chi Onwurah, a Labour MP who chairs Parliament's Science, Innovation and Technology Committee, sided with the minister in part. "There are certainly some problems in the OpenAI business model," she told BBC Radio 4. But she also acknowledged the UK's energy costs — among the highest in Europe — were not materially different from September.
Not everyone agrees with the government's read. Hugh Milward, Microsoft's UK vice president for external affairs, told MPs this week that energy costs, grid delays, and the government's abandonment of proposed copyright reforms have genuinely complicated AI infrastructure investment in the UK. Microsoft competes directly with OpenAI in AI services.
The UK government is launching a £500 million Sovereign AI Unit on Thursday, designed to help domestic AI companies scale without depending on American infrastructure. James Wise, an investor who will chair the unit, was blunt: the UK is "not the natural home" for large-scale AI data centers. The admission suggests the government has concluded that OpenAI and its peers cannot be relied upon — regardless of why they paused.
What to watch: whether OpenAI responds to the minister's challenge with specific documentation of regulatory or energy changes, or whether the company's silence lets Narayan's version stand. The next quarterly investor communication may clarify whether the UK pause reflects strategic reallocation or deeper financial pressure. Meantime, the Sovereign AI Unit will test whether the UK can manufacture AI independence, or whether that ambition was always a phantom.
