Nvidia, Microsoft, and OpenAI have collectively backed London-based AI infrastructure company Nscale with $700 million to dramatically expand the UK’s AI computing capacity. The partnership positions the UK as a major player in the global AI infrastructure race, with plans to deploy up to 58,640 Nvidia GPUs across the country and potentially scale to 300,000 globally.
What you should know: The investment transforms Nscale from a crypto mining spinoff into a cornerstone of Britain’s AI ambitions.
- Nscale emerged from Arkon Energy, a cryptocurrency mining company, and only exited stealth mode last year.
- The company didn’t exist when OpenAI launched ChatGPT in late 2022, highlighting its meteoric rise.
- This represents the most significant AI infrastructure deployment in UK history.
The big picture: Major tech giants are treating the UK as a critical battleground for AI supremacy, with Google already committing $6.8 billion to British AI initiatives.
- The collaboration deepens US-UK technology ties at a time when both nations are competing with China for AI leadership.
- Microsoft CEO Satya Nadella emphasized they are “building the digital infrastructure for the AI era, deepening the connection between the US and UK.”
Key infrastructure projects: Two massive computing facilities will anchor the UK’s AI capabilities.
- Nscale and Microsoft are building the UK’s largest AI supercomputer at Nscale’s Loughton campus, delivering 50MW of AI capacity scalable to 90MW.
- The facility will house 23,040 GB300 GPUs when it comes online in 2027.
- A separate “Stargate UK” platform, created by Nscale, OpenAI, and Nvidia, will focus on sovereign AI workloads with 8,000 Nvidia GPUs deployed in early 2025, expandable to 31,000.
Why this matters: The investment ensures British companies won’t be left behind in the AI revolution while strengthening national technological sovereignty.
- Nscale CEO Josh Payne emphasized the initiative demonstrates “the UK can be an AI maker, not a taker.”
- The infrastructure will provide compute access specifically for UK startups, scale-ups, and enterprises.
- OpenAI CEO Sam Altman noted the UK’s advantages: “world-class researchers, millions of ChatGPT users, and a government that quickly recognized the potential of this technology.”
What they’re saying: Industry leaders frame this as a pivotal moment for both AI development and international collaboration.
- “We are at the Big Bang of the AI era – and the United Kingdom stands in a Goldilocks position, where world-class talent, research and industry converge,” said Nvidia CEO Jensen Huang.
- “Stargate UK builds on this foundation to help accelerate scientific breakthroughs, improve productivity, and drive economic growth,” added OpenAI’s Sam Altman.
- “This historic commitment from Nscale shows how the UK can build the future of AI, together with our partners from the US,” said Nscale’s Josh Payne.

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
