Two of the world’s largest tech firms are set to make a major push into UK data centre development.

OpenAI and Nvidia are set to announce billions of pounds of investment in UK data centres next week alongside President Donald Trump’s visit to the country, Bloomberg reported.

The two companies will work with data centre and artificial intelligence infrastructure company NScale to build new facilities, according to Bloomberg.

London-based NScale is a startup that has been operational for less than two years, but it is already looking to raise billions of dollars of debt and equity to build out UK and European data centres.

It has pledged to invest $2.5B (£1.8B) in UK data centres over the next three years. In January, it bought a site in Loughton, Essex, east of London, which it said could house up to 45,000 of Nvidia’s GB200 super chips.

The investment will be highly anticipated in the UK data centre sector — big U.S. AI firms like OpenAI and chip firms like Nvidia have invested hundreds of billions in U.S. data centres, but their investment so far in the UK has been minimal.

Even before the big AI beasts cross the Atlantic, the UK data centre sector is growing fast — £14B was committed to new projects in the first half of the year, data from Cushman & Wakefield showed.
