“UK Version of Stargate” Launched! NVIDIA, Microsoft, and OpenAI Boost UK AI Infrastructure

TradingKey - During U.S. President Donald Trump’s state visit to the United Kingdom, the U.S. and UK governments announced a landmark "Tech Prosperity Agreement" on September 16, paving the way for major American tech companies to make large-scale investments in artificial intelligence and digital infrastructure in Britain.

Microsoft, OpenAI, Google, and others have pledged over £31 billion (approximately $42.3 billion) in investments in the UK over the coming years — marking a significant escalation in the global race to build AI infrastructure.

At the heart of the agreement, Microsoft announced it will invest more than $30 billion over the next four years to expand its cloud and AI capabilities in the UK. The company will partner with British firm Nscale to build the largest supercomputer in the UK, equipped with over 23,000 advanced GPUs. Microsoft CEO Satya Nadella described the move as “a double down on the UK.”

Google followed closely behind, announcing a £5 billion investment over two years to build new data centers, expected to create more than 8,000 jobs annually. Other tech leaders — including CoreWeave, Salesforce, Oracle, and Amazon — also announced additional multi-billion-pound investments, aiming to position the UK as Europe’s leading hub for AI innovation.

The centerpiece of this investment wave is “Stargate UK”, a project led by UK-based Nscale in collaboration with NVIDIA and OpenAI to develop world-class AI infrastructure.

NVIDIA CEO Jensen Huang said the UK is in a “golden position” and revealed plans to deploy 120,000 of its latest advanced GPUs in the country — the largest such deployment by NVIDIA in Europe to date. Of these, 60,000 Grace Blackwell Ultra GPUs will be deployed by Nscale. These chips incorporate semiconductor designs from Arm Holdings, headquartered in the UK, highlighting the growing importance of domestic technology within the global AI ecosystem.

OpenAI CEO Sam Altman stated that “Stargate UK” will accelerate scientific breakthroughs and economic growth. UK Prime Minister Keir Starmer called the agreement a “once-in-a-generation opportunity” and a “powerful vote of confidence” in the UK’s technological leadership.
