Sep 19, 2025 with Pippa Lamb
Key Points
- Nvidia's Jensen Huang committed $670 billion to UK cloud company Nscale and signaled potential $500 million investment in autonomous vehicle startup Wayve, anchoring a broader tech infrastructure push during the US-UK state visit.
- Microsoft and Google each pledged $30 billion to the UK over four years as Silicon Valley CEOs and the White House aligned on a Tech Prosperity Deal to standardize AI data models against Chinese competition.
- Revolut's $70 billion valuation gains momentum toward a potential IPO after Nvidia signaled investment interest, following Klarna's successful public debut and positioning the UK as a post-Brexit alternative to EU regulatory constraints.
Summary
The UK-US state visit this week functioned less as diplomatic ceremony and more as a structured investment showcase, with Silicon Valley's biggest names committing capital alongside White House officials at Windsor Castle and Chequers.
Microsoft announced a $30 billion commitment to the UK over four years, matched in scale by a separate Google pledge of approximately $30 billion, with $7 billion earmarked specifically for an existing UK data centre. The headline figure belongs to Nvidia: Jensen Huang committed $670 billion to Nscale, a UK cloud computing company, framing the investment as core infrastructure for making the UK an AI superpower. Huang also flagged a potential $500 million investment in Wayve, the UK autonomous vehicle company founded by Alex Kendall.
Attendees included Satya Nadella (Microsoft), Sam Altman (OpenAI), Alex Karp (Palantir), Brian Schimpf (Anduril), Tim Cook (Apple), and representatives from Blackstone and BlackRock. GSK announced significant investment into US R&D, signalling the deal flow ran in both directions.
The diplomatic output extended beyond investment pledges. The two governments signed a memorandum called the Tech Prosperity Deal, centred on aligning data model standards and ensuring the US-defined AI data stack remains dominant against Chinese competition. A separate commitment locked in the UK's full independence from Russian nuclear energy, directly addressing the energy infrastructure question that underpins AI expansion ambitions.
Prime Minister Keir Starmer is positioned by UK observers as pragmatically pro-business despite leading the traditionally left-leaning Labour Party. Tech CEOs present described the government's approach as execution-focused rather than ideological, a contrast drawn explicitly against the more restrictive regulatory posture of the EU. Post-Brexit positioning is central to that framing: the UK can pursue pro-AI policy without being constrained by EU risk-aversion frameworks.
The UK's pitch to investors rests on genuine R&D depth. Google DeepMind, ARM, Oxford and Cambridge research clusters, and advances in synthetic biology and pharma are cited as evidence that the country's growth engine is shifting from traditional City finance toward technology. The government views DeepMind's acquisition by Google as a cautionary tale and is actively building domestic AI infrastructure to retain future assets.
On the IPO front, Revolut remains the most watched name in European private markets. Its last reported valuation sits at $70 billion on a secondary basis. Huang signalled during the visit that Nvidia may invest in Revolut, adding further momentum to speculation around a potential listing. The broader IPO window is considered open following Klarna's successful public debut, though StubHub opened below its listing price, a reminder that selectivity still matters.
