UK, US Sign $42B Tech Prosperity Deal
The United Kingdom and the United States have finalized a landmark technology pact valued at $42 billion, aimed at strengthening cooperation in artificial intelligence, quantum computing, and nuclear technology. The agreement coincided with President Donald Trump’s two-day state visit to Britain, where he is scheduled to meet King Charles and Prime Minister Keir Starmer.
Tech Prosperity Deal
Dubbed the “Tech Prosperity Deal,” the pact commits U.S. technology giants—including Microsoft, Nvidia, Google, OpenAI, and CoreWeave—to major investments in the UK’s AI infrastructure. Funding will support data centers, advanced computer chips, and sovereign computing projects.
According to the UK government, the initiative is expected to create over 5,000 jobs in northeast England, which has been designated as a new AI growth zone. In addition, the countries will collaborate on research to advance targeted medical treatments, fusion energy, and other scientific priorities.
“This Tech Prosperity Deal marks a generational step change in our relationship with the U.S., shaping the futures of millions of people on both sides of the Atlantic, and delivering growth, security, and opportunity up and down the country,” Starmer said.
Major Corporate Commitments
Microsoft pledged $30 billion over four years, its largest UK investment to date, to build the country’s most powerful supercomputer, equipped with more than 23,000 advanced AI chips. Nvidia will partner with British companies to deploy 120,000 GPU chips, marking its largest European rollout to date.
“Today marks a historic chapter in U.S.–United Kingdom technology collaboration,” said Nvidia founder and CEO Jensen Huang.
OpenAI also announced a partnership with UK firm Nscale and Nvidia to launch the Stargate UK project, designed to enhance the country’s sovereign computing capabilities.
Trade and Nuclear Agreements
The pact follows a June trade agreement signed during the G7 summit in Canada, although UK steel and aluminum remain subject to 25 percent U.S. tariffs. Before departing for Britain on Sept. 16, Trump signaled willingness to revisit aspects of the trade deal, telling reporters: “They want to see if they can refine the trade deal a little bit. We made a deal, and it’s a great deal. And I’m into helping them.”
Trump’s visit marks his second state trip to the UK; his first occurred in 2019 when he was hosted by Queen Elizabeth II.
A fact sheet from the U.S. Trade Representative’s office in May highlighted ongoing disputes over the UK’s Digital Services Tax, which Washington views as discriminatory against American firms. It remains unclear if Trump will address the issue during his meetings.
Just one day before his arrival, the two governments signed a separate nuclear energy agreement that London described as a move to “turbocharge the build-out of new nuclear power stations” in both countries.
