President Donald Trump and UK Prime Minister Keir Starmer on Thursday formalized a $350 billion investment agreement covering AI, civil nuclear energy, and quantum computing, signing a joint memorandum of understanding.

The leaders unveiled the Technology Prosperity Deal at a press conference at Chequers, Starmer’s countryside residence in Buckinghamshire, northwest of London. They said the pact could generate up to 17,500 new jobs across the United States and the United Kingdom.

“This trip has galvanized $350 billion in deals across many sectors, and we’re committed to ensuring that the UK is a secure and reliable supply of the best AI, hardware and software on Earth, and we supply that and make sure we supply it in quantity to the UK,” Trump said.

The president added humorously that it was “a better deal for you than us,” commending Starmer as a formidable negotiator. Starmer described the agreement as “a good deal” for both nations.

“It’s a blueprint to win this new era together, shape it according to our shared values, and seize the incredible opportunities that are on offer,” Starmer told reporters.

Starmer also highlighted the role of private sector partners, stating, “We have huge new investments from Nvidia, Nscale, Open AI, Google, Salesforce and many more backing cutting-edge British jobs for years to come.”

The deal is expected to create roughly 15,000 jobs in the UK, alongside the construction of 12 advanced nuclear reactors in northern England, while 2,500 jobs are anticipated in the US.

The nuclear projects are projected to provide energy for up to 1.5 million homes, with both governments optimistic the initiative will help meet energy needs on both sides of the Atlantic.

Trump emphasized collaboration on “quantum computing, fusion, 6G and civil nuclear energy,” noting that the memorandum balances deregulatory measures with an emphasis on innovation. The AI components of the deal will include joint research programs and a US-UK space partnership.

The agreement also calls for increased chip and data center exports, as well as closer cooperation between the US Center for AI Standards and Innovation and the UK AI Security Institute, which oversee industry regulations.

New nuclear policies are designed to power the technology expansion while reinforcing non-proliferation and security programs. Significantly, the UK aims to achieve “full independence from Russian nuclear fuel by the end of 2028,” the White House said.

Quantum technology developments are expected to accelerate computing capabilities to “transform defense, finance, and healthcare, protect [US and UK] citizens, and create high-skilled jobs.”

The memorandum will take effect by mid-March 2026, with formal annual progress discussions beginning in 2026.

“Firming up international relationships will be critical to American AI success,” Matthew Mittelsteadt, a tech policy researcher at the libertarian Cato Institute, told The Post.

“To lead this space, the United States needs markets, capital, and data — ‘resources’ that mutually beneficial trade partnerships and openness can provide,” Mittelsteadt added. “As the United States continues negotiations, we should strongly reconsider our current protectionist stance so we can further deepen ties with the UK and others, and reap the benefits of the resources and openness that will follow.”
