Microsoft Corp. is injecting $30 billion into artificial intelligence (AI) infrastructure across the UK over the next four years, capping a massive week for the region, which just landed another AI deal with Google.
The software giant’s agreement, announced in a blog post Tuesday, includes a $15 billion investment to expand AI and cloud infrastructure, marking the company’s largest financial commitment to date in the UK. Funding will go toward building the UK’s largest supercomputer with 23,000 NVIDIA GPUs in partnership with Nscale, and broadening Microsoft’s data center capacity to support local customers. Contours of the accord reportedly also call on OpenAI to supply technology. (The announcement follows a $3.2 billion investment in AI infrastructure that Microsoft made in Britain two years ago.)
Under the $30 billion contract, Microsoft said it will invest the funds between 2025 and 2028, with half allocated to data centers and AI infrastructure and the rest to UK operations, creating skilled jobs, expanding partnerships, and reinforcing transatlantic ties.
Microsoft said it has trained more than one million people in AI skills, with research hubs in Cambridge and London supporting the UK’s role in responsible innovation. The $15 billion deal is part of the UK–US Technology Partnership and aligns with AI strategies from President Donald Trump and British Prime Minister Keir Starmer. The company credited government reforms on planning, energy capacity, and regulation for making the investment possible.
“Microsoft’s landmark investment is a powerful vote of confidence in UK’s leadership in AI and cutting-edge technology,” Starmer said in a statement. “This commitment will not only strengthen our digital infrastructure and support thousands of highly skilled jobs, but also ensure Britain remains at the forefront of global innovation as we deliver on our Plan for Change.”
In a video disclosing the investment, Microsoft CEO Satya Nadella said the company has been in the UK for more than 40 years, employing 6,000 people across AI and research labs and game studios.
The mega announcements coincide with President Donald Trump’s visit to the UK this week, which is seen as part of a broader effort to boost the presence of U.S. firms like NVIDIA and OpenAI in AI. NVIDIA CEO Jensen Huang and OpenAI CEO Sam Altman are scheduled to join President Trump during his visit this week.
