OpenAI pauses Stargate UK data centre project over energy costs and copyright rules

OpenAI has paused its ambitious Stargate UK data centre project due to soaring energy costs and regulatory hurdles around AI copyright, derailing a key part of a major transatlantic tech investment push.^[1][2] The initiative, announced in September 2025 alongside Nvidia and UK firm Nscale, was set to deploy 8,000 GPUs initially at sites in north-east England, with potential scaling to 31,000 GPUs.^[1] According to reports from The Next Web, these challenges—particularly Britain's high industrial electricity prices and an unfavorable environment for AI-related copyright rules—proved insurmountable for now.^[1]

This pause strikes at the heart of the UK-US Tech Prosperity Deal, a multibillion-pound package hailed as a pathway to making Britain an AI superpower.^[2][3] Unveiled last year, the deal included over £31 billion in commitments from US tech giants: £22 billion from Microsoft for cloud and AI infrastructure with Nscale and Nvidia, up to £11 billion from Nvidia for "AI factories" and quantum tech, and £5 billion from Google for a data centre in Hertfordshire.^[2][3] Nvidia CEO Jensen Huang had publicly predicted the investments would propel the UK to global AI leadership, aligning with the nation's engineering strengths, ethical standards, and research ecosystem, as noted by experts from the Institution of Engineering and Technology (IET).^[1]

The Stargate project was positioned as a cornerstone, promising thousands of British jobs and bolstering the UK's position in the global AI race without heavy reliance on rival powers like China.^[2] For startups and innovators, it represented a "gold rush" by democratizing access to massive compute power via Europe's largest planned GPU cluster by 2026, fostering transatlantic growth on trusted infrastructure.^[3] OpenAI's involvement underscored the deal's prestige, building on the UK government's broader AI Opportunities Action Plan to strengthen education, research, and infrastructure.^[6]

The halt raises immediate questions for affected stakeholders in north-east England, where the data centres were slated to create high-skilled employment and stimulate local economies.^[1][2] Broader implications ripple through the UK's tech sector, which has leaned on these foreign infusions to compete globally—critics already argue that "AI superpower" ambitions ring hollow without more homegrown investment.^[7] As reported by the BBC, the project was explicitly tied to the superpower narrative, amplifying concerns over energy policy and intellectual property frameworks that could deter future deals.^[2]

Looking ahead, the pause leaves the Tech Prosperity Deal's momentum in doubt, with no clear timeline for resumption.^[1][2] Industry observers, including those from RUSI, emphasize that while the initial investments were a "big, beautiful" boost, sustaining AI leadership will require addressing these structural barriers—such as electricity pricing and regulations—to keep the UK attractive to Silicon Valley players.^[2] The government and partners like Nvidia may need to pivot, potentially accelerating alternative sites or policy reforms to salvage the vision of a thriving British AI ecosystem.^[1][3]
