- The US decision to pause the Tech Prosperity Deal — worth around £31 billion — highlights tensions in current UK–US trade and regulatory talks.
- The agreement had aimed to deepen cooperation in areas including artificial intelligence, quantum computing and civil nuclear energy.
What happened: US pauses implementation of UK technology pact
The United States has put on ice the implementation of a high-profile technology cooperation agreement with the United Kingdom, first announced during President Donald Trump’s state visit to London in September. Known as the Tech Prosperity Deal, the pact was designed to boost bilateral collaboration on artificial intelligence, quantum computing and civil nuclear energy, and to unlock significant private-sector investment into the UK technology sector.
British officials confirmed the pause this week, with sources saying Washington’s decision reflects frustration over a wider set of trade and regulatory disagreements that fall outside the scope of the tech agreement itself. Among the issues cited are the UK’s continued use of a digital services tax on large American technology companies and regulatory differences in sectors such as food safety and industrial goods, which the US government has been pressing London to address.
Although the exact figure associated with the deal has been reported in the region of £31 billion, including substantial investment pledges from companies such as Microsoft and Google, the suspension means that these commitments will not proceed as initially planned until broader trade negotiations make progress.

Why it’s important
The pause in implementing the Tech Prosperity Deal signals a notable strain in what both sides had marketed as a cornerstone of the UK–US partnership. The agreement was intended not only to promote technology cooperation but also to attract tens of billions in private investment and to position the UK as a global hub for next-generation tech like AI and quantum.
Now, with Washington linking progress on the pact to wider concessions on tariffs, regulatory alignment and market access, the suspension highlights the complexity of modern trade diplomacy — where technology policy, taxation and broader economic interests intersect. For the UK government, which had positioned the Tech Prosperity Deal as a generational step in bilateral economic relations, the development represents a diplomatic setback and may prompt reassessment of strategy ahead of further talks scheduled early next year.
