President Donald Trump and UK Prime Minister Keir Starmer signed the “Tech Prosperity Deal” at Chequers, securing billions in US investment for Britain’s tech sector. Microsoft pledged $30 billion, Google $6.7 billion, and Nvidia announced a $14.9 billion supercomputer project. The deal, focused on AI, quantum computing, and nuclear power, underscores transatlantic cooperation and may reshape the UK’s economic future, alongside a separate $203 billion package announced earlier.
President Donald Trump and British Prime Minister Keir Starmer on Thursday signed the “Tech Prosperity Deal” at Chequers, at the prime minister’s country residence, marking a major step in US-UK cooperation on advanced technology. The deal focuses on artificial intelligence (AI), quantum computing, and nuclear power, while unlocking billions in fresh investment from American tech giants.
The signing, held at Buckinghamshire, was a highly symbolic moment of the state visit. Trump and Starmer held up signed documents for the cameras, watched by top executives from some of the world’s most powerful companies, including Microsoft, Google, Nvidia, OpenAI, and Rolls-Royce.
Microsoft announced the largest package, pledging $30 billion (£22 billion) to expand its AI research, cloud computing, and data infrastructure in the UK. Its biggest investment outside the United States. Google followed with around $6.7 billion (£5 billion) commitment over two years to boost AI research and digital infrastructure.
Chipmaker Nvidia unveiled a $678.32 million (£500 million) plan to build new data centers to support Britain’s AI ambitions. Its CEO Jensen Huang went further, revealing that Nvidia will partner with UK firm Nscale and US provider CoreWeave to develop an $14.9 billion (£11 billion) supercomputer in Britain, which he said would be the largest AI infrastructure project in Europe.
“The UK has some of the best researchers and universities, and a vibrant AI start-up ecosystem,” Huang told the BBC. “What it needs is infrastructure and this is the goldilocks moment.”
The deal is designed to reinforce the UK’s role as a hub for technological innovation while strengthening transatlantic economic ties. At the signing, Starmer said the agreement would ensure that opportunities and revenue from breakthrough technologies “circulate back into our communities.” Trump called it a sign of the United States’ enduring commitment to Britain and the “special relationship.”
The event came just a day after the Trumps attended a state banquet at Windsor Castle, where corporate leaders including Satya Nadella, Sam Altman, Jensen Huang, and Rupert Murdoch were in attendance.
Business analysts noted that the Tech Prosperity Deal, separate from the $203.4 billion (£150 billion) investment package announced earlier in the week, may prove even more consequential for Britain’s long-term economic trajectory.
