AI drove a refreshed special relationship between the UK and US this week after Microsoft, Nvidia, Google and OpenAI confirmed massive investments and commitments to the nation.

The flurry of announcements were anticipated by several news outlets, timed to coincide with a state visit to the UK by US President Donald Trump.

Investments detailed by Google, Nvidia and Microsoft alone totalled £45 billion, while OpenAI intends to house thousands of GPUs in the UK as part of its Stargate initiative.

Add to this a target by the UK government to attract £30 billion of investment by creating an AI growth zone in North-East England and it has been a good week for the nation’s standing in the technology.

Here’s a rundown of the moves announced.

Nvidia
The company is partnering with domestic AI infrastructure company Nscale to deliver up to 60,000 of its Grace Blackwell GPUs to the UK, adding to a global move involving up to 300,000 of the units.

Nvidia and Nscale also plan to invest up to £11 billion in UK AI factories in a deal involving CoreWeave. The US company branded this the largest deployment of relevant infrastructure in the UK’s history, one involving up to 120,000 of its Blackwell GPUs.

The result should be a series of AI factories tailored towards leading models which will boost UK sovereignty and its economy, Nvidia explained. The plan is to have these up and running by the close of 2026.

CEO Jensen Huang (pictured, right) said the nation is gearing up for an “AI industrial revolution, advancing science, transforming industries and creating new economic opportunities”.

He branded the nation’s “world-class expertise, outstanding universities and vibrant industries” as a “Goldilocks ecosystem”.

Microsoft
The software giant detailed a $30 billion (£21.9 billion) investment in AI infrastructure and operations running from this year until 2028, noting it is its largest financial commitment to the nation.

Capex is set to account for half the sum, with Microsoft intent on building the biggest supercomputer in the UK. There is a crossover, with this element involving 23,000 Nvidia GPUs and a partnership with Nscale.

Some of the $15 billion is also allocated towards expanding its datacentre footprint. Microsoft noted the UK National Health Service, banking group Barclays and the London Stock Exchange are among its customers.

Microsoft stated the other half of its investment would go towards operational expenses, in particular its 6,000 staff in the UK who are developing AI models, products and games, and running its datacentres, and sales and support services.

The company noted the support of the UK government was key in its ability to commit the massive sum to the nation.

HM Government
The government appeared keen to spread the benefits with its AI Growth Zone plan, which it hopes will unlock more than 5,000 new jobs along with billions in investment.

It stated the goal is to expand on current regional skilling programmes and support a local ambition to become one of Europe’s biggest data centre hubs.

The government noted asset management company Blackstone committed £10 billion to a site in Blyth.

It earmarked Cobalt Park as a second area involved in the North-East England programme.

OpenAI
The company backed the UK as the latest market where its Stargate J/V would have a presence, planning to allocate up to 8,000 GPUs in Q1 2026 to run its AI models in the nation.

OpenAI is working with Nvidia and Nscale on the move and noted it builds on a memorandum of understanding struck with the UK government in July involving infrastructure needs and AI adoption.

Nscale’s involvement links OpenAI’s plans with the UK government’s growth move, with capacity for Stargate set to be included in the Cobalt Park site. Nvidia is due to bring its “most advanced GPUs” to the table.

OpenAI looked beyond infrastructure, detailing an ambition to work with domestic business leaders and the government to “design flexible and customisable learning experiences” for AI.

Altman praised the UK for its pioneering approach to AI, “world-class researchers, millions of ChatGPT users and a government that quickly recognised the potential of this technology”.

Google
The search giant is lining up a further £5 billion investment in the UK over the next two years, with a heavy focus on scientific research and its DeepMind efforts.

Google detailed the investment at the opening of a data centre which itself was hailed as a “powerful vote of confidence” in the nation by Chancellor of the Exchequer Rachel Reeves, who opened the facility.
