US Tech Giants Pledge Billions in UK Investments During Trump Visit
US tech giants including Microsoft, Google, and Nvidia have pledged over $40 billion in UK investments, primarily in AI and technology infrastructure, coinciding with President Trump’s state visit to the United Kingdom.
US technology giants have announced more than $40 billion in new investments in the United Kingdom, marking a significant boost for the British tech sector as President Donald Trump begins his second state visit to the country on September 17, 2025. The commitments, led by Microsoft, Google, Nvidia, and other major firms, are expected to accelerate the UK’s ambitions in artificial intelligence, quantum computing, and digital infrastructure.
Major Pledges and Strategic Partnerships
Microsoft revealed plans to invest $30 billion in AI infrastructure and operations in the UK through 2028, its largest commitment to the country to date. Google followed with a $6.8 billion pledge focused on AI, research and development, and engineering over the next two years. Nvidia, OpenAI, and British firm Nscale are collaborating on a new AI infrastructure project, Stargate UK, which will be based in the North East and powered by Nvidia’s advanced graphics processing units. Additional investments include CoreWeave’s $2 billion for AI data centers and Salesforce’s $2 billion expansion through 2030. BlackRock is also investing £500 million in UK data centers.
The UK government, in tandem with these announcements, unveiled the Tech Prosperity Deal with Washington, aimed at fostering collaboration in fast-growing technologies such as AI, quantum computing, and nuclear energy. The agreement includes the creation of a joint taskforce to advance quantum research and streamline nuclear power station development, with the goal of reducing licensing timeframes and accelerating deployment.
Political and Economic Context
The investment wave comes as President Trump is welcomed by King Charles III and meets with Prime Minister Keir Starmer. The visit is marked by both ceremonial events and high-level economic talks, with a focus on deepening transatlantic ties in technology and trade. Treasury Secretary Scott Bessent is also in London for discussions with UK officials and business leaders. While the UK has secured a temporary reduction in US steel tariffs to 25%—lower than the 50% imposed on most other countries—broader trade negotiations remain ongoing.
Industry leaders, including Nvidia CEO Jensen Huang and OpenAI’s Sam Altman, are accompanying the US delegation, underscoring the strategic importance of the UK as a hub for AI talent and research. The UK’s Technology Secretary Liz Kendall described the Tech Prosperity Deal as a vote of confidence in Britain’s AI sector, which has lagged behind the US but is now positioned for rapid growth.
Implications for the UK Tech Sector
The influx of US capital is expected to create thousands of jobs, expand the UK’s data and AI infrastructure, and enhance its competitiveness in emerging technologies. The Stargate UK project, in particular, is set to provide the computing power needed for advanced AI research and applications, with potential benefits for healthcare, defense, and space exploration. The government’s partnership with US firms is also seen as a move to close the gap with Europe, which has struggled to match the scale of US tech investment since the launch of OpenAI’s ChatGPT in 2022.
Despite the optimism, some sectors remain cautious, noting that the regulatory environment for digital assets and crypto remains a point of divergence between the US and UK. Nonetheless, the scale of the new investments signals a deepening of economic and technological ties between the two countries, with the UK emerging as a key player in the global AI race.
