President Donald Trump’s second state visit to Britain was not only marked by ceremonial grandeur but also by a significant surge in transatlantic technology investments, particularly in artificial intelligence (AI) and data centre infrastructure. This visit underscored the UK’s growing role in the global AI race, largely fuelled by the declarations of commitment from some of the most powerful players in US technology, specifically members of the so-called ‘Magnificent Seven’—Alphabet (Google), Microsoft, and Nvidia.

These technology giants, through a collective initiative known as the Tech Prosperity Deal, have pledged billions in investment to foster closer UK-US collaboration in areas including AI, quantum computing, and civil nuclear energy. Microsoft alone announced an extraordinary £22 billion investment in cloud and AI infrastructure, which includes plans to build the UK’s largest AI supercomputer in Loughton. Nvidia committed to deploying 120,000 of its latest Blackwell GPUs across the UK, marking its largest European rollout. Google intends to invest £5 billion in UK AI research and infrastructure, including a major new data centre in Hertfordshire designed to support AI-powered services such as Google Cloud and Maps. This facility will be powered predominantly by renewable energy and incorporate innovative cooling and energy storage systems to address increasing energy demands.

These commitments collectively form part of a wider £150 billion investment influx from US firms, validation of Prime Minister Keir Starmer’s strategic decision to align the UK more closely with the US in the global AI competition, especially vis-à-vis China. This investment includes significant stakes from private equity giant Blackstone (£100 billion) and Microsoft (£22 billion), framing the UK as a critical hub for future technology growth.

Central to this technological transformation is the expansion of data centres, the physical backbone that supports AI and cloud computing. The number of UK data centres is expected to rise by 20% by 2030, with a target to reach six gigawatts of capacity to meet unprecedented power needs. An AI search, for example, is estimated to consume ten times the energy of a typical online search, underscoring the infrastructure’s energy intensity. Investment trusts specialising in these facilities are already positioned to benefit: Tritax Big Box is developing multiple data halls near Heathrow with a low-carbon power supply, and Segro is expanding its portfolio of urban and big-box warehouses with fitted-out data centres aimed at premium tenancy agreements. Analysts have forecasted growing rental income and raised share price targets, with JP Morgan optimistic about Tritax and Goldman Sachs upgrading their outlook on Segro.

Nevertheless, the construction of these data centres is not without challenges. The ageing national grid was not designed for this scale of consumption, and there are increasing concerns about resource usage, particularly water for cooling and rising electricity consumption, with data centres forecast to demand 6% of the UK's electricity by 2030, up from 1% today. These energy requirements have prompted environmental and public scrutiny, threatening to prompt backlash over potential increases in energy costs.

To hedge against such risks, some investors are turning to infrastructure funds with holdings in energy companies involved in renewables, such as National Grid and NextEra Energy, recognising the critical role of sustainable energy in supporting the tech ecosystem’s expansion.

Despite the enthusiasm, caution remains warranted. Market observers warn of potential over-optimism around the accelerated build-out of data centres and AI infrastructure. The historic risk of technology bubbles looms if the anticipated productivity boosts from AI fail to materialise as hoped. OpenAI’s CEO Sam Altman, speaking during the same visit, expressed measured caution, reflecting a broader sentiment among investors and analysts, including Goldman Sachs, who remain vigilant for early signs of market stress even as they acknowledge AI’s transformative potential.

Beyond data centres, Nvidia is eyeing further deep-rooted investments in UK AI innovation, with a potential $500 million injection into Wayve, a British autonomous driving startup renowned for its machine learning-driven approach rather than reliance on pre-mapped routes. This aligns with Nvidia’s broader £2 billion commitment to nurturing the UK’s AI startup ecosystem.

In sum, Britain’s ambition to become an AI superpower is matched by massive financial commitments from leading US tech players, supported by government policy and infrastructure investments. However, realising this vision will require navigating significant logistical, environmental, and market risks. For investors and policymakers alike, balancing optimism with prudence is the key as this technological transformation unfolds.
