Nvidia-Backed Startup Nscale, Microsoft Strike AI Infrastructure Deal

By Mauro Orru

Nscale Global Holdings said it reached an agreement with Microsoft to roll out artificial-intelligence infrastructure in the U.S. and Europe, the latest partnership for the startup after weeks of dealmaking.

The U.K.-based company said Wednesday that it would deploy roughly 104,000 Nvidia GB300 graphics processing units at an AI campus in Texas and about 12,600 Nvidia GB300 GPUs at a data center in Sines, Portugal. The deal is aimed at delivering Nvidia AI infrastructure services for Microsoft.

Nscale didn't disclose financial details for the agreement, which it described as one of the largest AI infrastructure contracts ever signed. The company, which owns data centers that provide the networking, storage and computing needed to power AI, has struck several partnerships in recent weeks, including with ChatGPT maker OpenAI.

Last month, Nscale said it would roll out AI infrastructure in the U.K with Nvidia and OpenAI as part of a project dubbed Stargate U.K. The company also said it plans to develop the U.K.'s largest AI supercomputer with Microsoft.

In July, Nscale said it was partnering with Norwegian industrial group Aker and OpenAI to set up Stargate Norway, a data-center project in northern Norway that is expected to house 100,000 Nvidia GPUs.

The latest agreement with Microsoft comes weeks after Nscale closed a $1.1 billion Series B funding round that it said was the largest in European history. Nvidia, Dell Technologies, Nokia have injected funds into the startup.

News Corp, owner of Dow Jones Newswires and The Wall Street Journal, has a content-licensing partnership with OpenAI.
