OpenAI has put on hold plans for a major project intended to bolster the UK’s artificial intelligence capabilities, citing high energy costs and regulation as the reasons for the decision.
The project, known as Stargate UK, was part of the landmark UK-US AI deal announced last September. At the time, US companies appeared to commit £31bn to the UK’s technology sector as part of a wider package of investments aimed at bringing AI more deeply into the British economy.
The pause marks a setback for one of the most high-profile AI investment plans linked to the UK’s growth strategy. Stargate UK had been framed as a significant component of efforts to strengthen the country’s position in the rapidly expanding AI industry.
According to the source, OpenAI cited two main pressures behind the move: the cost of energy and the regulatory environment. Both factors have increasingly shaped debates around where major AI infrastructure can be built and scaled, especially as companies seek large amounts of power to support data centres and related systems.
The decision comes as governments and technology firms continue to weigh how to expand AI capacity while managing the practical challenges that come with it. For the UK, the project’s suspension raises questions about the pace at which promised investment in the sector may be delivered.
Stargate UK formed part of a broader wave of announcements tied to the UK-US deal last year. That agreement was presented as an effort to accelerate AI development and encourage new investment in Britain’s tech base.
No further details were included in the source about whether the project might be revived later or what next steps OpenAI may take. For now, the company has simply placed the plan on hold.
