Nvidia (NASDAQ:NVDA) said it is working with CoreWeave (NASDAQ:CRWV) Microsoft (NASDAQ:MSFT) Nscale and OpenAI to build U.K.’s AI infrastructure for boosting innovation, economic growth, and jobs.
The U.S. tech giant noted that by the end of 2026, the companies will build and operate AI factories that will serve leading AI models, including those from OpenAI, to enable the U.K.’s sovereign AI goals for building a platform to power innovation and growth.
The announcements were unveiled three months after U.K.’s Prime Minister Keir Starmer and Nvidia’s Founder and CEO Jensen Huang announced a collaboration at London Tech Week. The announcements were unveiled in honor of transatlantic technology and trade partnership during U.S. President Donald Trump’s state visit to the U.K.
Nvidia will partner with British AI infrastructure company Nscale to scale up 300,000 Nvidia Grace Blackwell Graphics processing units, or GPUs, in AI factories across the U.S., Portugal and Norway, with up to 60,000 GPUs in the U.K.
Nvidia, Nscale, CoreWeave and others plan to invest up to £11B in U.K. AI factories with up to 120,000 Blackwell GPUs — representing the largest AI infrastructure rollout in the country’s history — and will power initiatives such as OpenAI’s Stargate U.K.
Nscale, OpenAI and Nvidia are establishing Stargate U.K., which will feature Blackwell Ultra GPUs operating in Nscale’s U.K. data centers by 2026.
OpenAI is expected to use this Nvidia infrastructure to serve its models — including the latest and most advanced reasoning model, GPT-5.
In addition, Nscale and Microsoft announced plans to build the U.K.’s most powerful supercomputer in Loughton. It is expected to feature over 24,000 Grace Blackwell Ultra GPUs to provide Microsoft Azure services in the U.K.
Nvidia noted that it is boosting U.K. quantum computing with multiple initiatives including teaming with Oxford Quantum Circuits, or OQC, to build a quantum-GPU AI supercomputing center.
Based out of Digital Realty’s JFK10 facility in New York City, the OQC GENESIS system in the new center will harness the NVIDIA CUDA-Q platform to bring together OQC’s quantum computing technology, Nvidia’s AI infrastructure and Digital Realty’s data center interconnection and colocation expertise to provide businesses with secure, scalable access to integrated quantum-GPU computing, the company added.
Nvidia is collaborating with techUK, alongside robotics and automation firm Quanser and training provider QA, to strengthen the U.K.’s robotics and AI ecosystem.
In addition, Nvidia said that U.K. foundation models UK-LLM, Nightingale AI and PolluGen and AI leaders across agentic and generative AI, quantum, life sciences, finance and robotics such as ElevenLabs, Isomorphic Labs, JLR, Nscale, Oxa, Revolut, Synthesia and Wayve are building on the Nvidia AI stack.
Nvidia noted that BlackRock recently announced it will invest up to £500M to modernize U.K. data centers in partnership with Digital Gravity Partners. These data centers will be refurbished to be Nvidia-ready, according to the company.
