Nscale has entered into an expanded agreement with Microsoft to deploy around 200,000 Nvidia GB300 graphics processing units (GPUs) of hyperscale Nvidia AI infrastructure deployments in Europe and the US.
The multi-year agreement is intended to deliver Nvidia-based AI infrastructure services to Microsoft. It also aims to address EU-specific data sovereignty requirements for regional customers.

This agreement follows the September 2025 announcement by Nscale and Microsoft regarding the establishment of the UK’s largest Nvidia AI supercomputer at Nscale’s Loughton AI Campus.
Dell Technologies is working with Nscale and Microsoft on this project.
Under the contract, Nscale will provide nearly 104,000 Nvidia GB300 units to a 240MW hyperscale AI campus in Texas, where phased delivery of AI infrastructure services will begin for Microsoft in the third quarter of 2026.
The Texas facility, leased from Ionic Digital, is planned to scale up to 1.2GW, with Microsoft retaining an option to activate a 700MW second phase from late 2027.

The company operates as a vertically integrated AI cloud provider with global data centre infrastructure, GPU clusters, orchestration, and AI services.
Nscale founder and CEO Josh Payne said: “This agreement confirms Nscale’s place as a partner of choice for the world’s most important technology leaders.
“Few companies are equipped to deliver GPU deployments at this scale, but we have the experience and have built the global pipeline to do so.”
Recently, Microsoft launched ExCyTIn-Bench open-source benchmarking tool designed to evaluate the performance of AI systems in cybersecurity investigations.
