Two US tech leaders have unveiled major new UK investment plans, strengthening Britain’s role as a global hub for artificial intelligence and digital infrastructure.
CoreWeave, the AI-focused cloud provider, announced the next $1.5 billion phase of its £2.5 billion UK programme, expanding data centre capacity to support AI labs, enterprises, startups and public sector bodies. The company will work with Nvidia and Scottish partner DataVita to deliver GPU-powered infrastructure running entirely on renewable energy, with advanced closed-loop cooling to cut water use.
CEO Michael Intrator said the build-out will establish “one of the world’s largest concentrations of sustainable compute,” fuelling economic growth and scientific discovery. London is now CoreWeave’s European headquarters, while new sites in Crawley and Docklands are already among Europe’s largest AI hosting facilities.
Salesforce also confirmed it will raise its UK investment to $6 billion through 2030, establishing London as its AI hub for Britain and Europe. Plans include new research teams and the launch of its first AI Centre in the capital. Despite previous job cuts in 2024, CEO Marc Benioff said the move reflects Salesforce “doubling down” on its UK commitment.
The announcements coincide with a wave of US-led investment under the newly signed £31 billion US–UK Tech Prosperity Deal, agreed during President Donald Trump’s 2025 state visit. The pact includes £22 billion from Microsoft to build Britain’s largest AI supercomputer, £5 billion from Google to expand data centres, and Nvidia’s deployment of 120,000 GPUs across the UK.
OpenAI and Nvidia are expected to follow with further multi-billion-pound UK projects, supporting the drive for sovereign AI infrastructure to enhance economic resilience and national security.
Prime Minister Keir Starmer welcomed the commitments as evidence that the UK’s light-touch regulatory model is attracting global tech leaders, adding that sustainable practices such as CoreWeave’s renewable-powered centres align with the government’s vision for responsible innovation.
Together, the investments paint a picture of an accelerating AI ecosystem in Britain—fuelled by deep-pocketed US partners, government support, and a focus on sustainability—positioning the UK as a magnet for the next wave of AI innovation.
