About Nscale
Nscale is a vertically integrated AI infrastructure company founded in 2024 and headquartered in London, UK. The company designs, builds, and operates data centers and GPU cloud infrastructure aimed at supporting the training, deployment, and scaling of AI models, controlling elements of the stack from energy sourcing and data center construction to compute and software layers.
The company's core offering is GPU cloud capacity on Nvidia hardware for AI model training and inference, and its customers include Microsoft, OpenAI and Anthropic. It operates data centers in the UK, the US, Norway, Portugal and Iceland, and its projects include a supercomputer for Microsoft at its Loughton campus in Essex and the Stargate UK and Stargate Norway data centers with OpenAI.
Nscale says it has raised over $3.3 billion through series financing since its May 2024 spin-out from Arkon Energy, including a $1.1 billion Series B led by Aker ASA in September 2025 and a Series C announced in March 2026 at a $14.6 billion valuation; its investors include Nvidia, Dell, Nokia and Sandton Capital. It had over 1,000 full-time employees as of August 31, 2026, and in September 2026 it filed a registration statement with the SEC for a proposed initial public offering on the New York Stock Exchange.
