President Donald Trump is currently in the United Kingdom for a historic second state visit, hosted by King Charles III from 16–18 September 2025. As “votes of confidence” in the UK economy and as part of a renewed US–UK technology partnership, major US companies have announced significant investments in the UK to coincide with the President"s UK visit.
Today, Microsoft announced a $30 billion investment that includes both AI infrastructure and ongoing operations across the UK over the four years from 2025 through 2028. Microsoft highlighted that this is the largest financial commitment the company has ever made in the UK.
Of the $30 billion, $15 billion will be used to build out cloud and AI infrastructure in the UK. As part of this investment, Microsoft will be developing the UK"s largest supercomputer using more than 23,000 NVIDIA GPUs in partnership with Nscale.
We’re committed to creating new opportunity for people and businesses on both sides of the Atlantic, and ensuring America remains a trusted and reliable tech partner for the United Kingdom.

The other $15 billion investment will support Microsoft"s existing operations across the United Kingdom. Microsoft currently has about 6,000 employees working on advanced research, AI model development, product development, game development, and more.
Brad Smith, Vice Chair and President at Microsoft, said the following regarding Microsoft"s $30 billion investment:
As we move forward, we’re encouraged by Prime Minister Starmer’s focus on growing the UK economy. Our ability to make an investment of this size is based in no small measure on the work the Government is doing to reform planning, grow electricity capacity, and foster a more stable and open regulatory environment.
Similarly, Google has announced a £5 billion investment that includes capital expenditure, research and development, and related engineering. Google"s investment is projected to create 8,250 jobs annually at UK businesses.
