Microsoft Rejects Expansion of Multibillion-Dollar AI Computing Deal With UK’s Nscale

Texas — Microsoft Rejects Expansion of Multibillion-Dollar AI Computing Deal With UK’s Nscale

Microsoft has declined an option that would have more than doubled its agreement to lease AI computing capacity from British infrastructure company Nscale at a Texas data center.

The decision leaves the existing contract intact and does not change Nscale’s disclosed total contract value of approximately $103 billion.

Microsoft has decided not to expand its existing artificial intelligence infrastructure partnership with UK-based Nscale, turning down an option that could have substantially increased the value of their agreement.

A person familiar with the matter said Microsoft will not exercise an option to more than double the computing capacity it leases from Nscale at a Texas data center.

The Financial Times first reported the development on Thursday, November 5, describing the potential expansion as a deal worth tens of billions of dollars for Nscale.

The decision, however, does not affect the companies’ existing agreement in Texas.

The source, who spoke anonymously because the information is confidential, said Microsoft reached its decision several months ago, before Nscale filed its initial public offering documents in September.

Microsoft and Nscale initially entered into an agreement last year covering the deployment of approximately 200,000 artificial intelligence chips produced by Nvidia.

The partnership included Nscale’s data-center operations in the United States and Europe.

Microsoft’s decision to abandon the potential Texas expansion follows other adjustments to the companies’ infrastructure plans.

Several weeks earlier, Microsoft pulled out of an agreement that would have made it the anchor customer for Nscale’s flagship data-center project in Loughton, Essex.

That decision came after electricity connection delays pushed the anticipated availability of power supplies into the 2030s.

Despite the decision not to take on additional Texas computing capacity, Nscale continues to hold substantial commercial commitments.

In documents filed for its IPO, the company reported signing statements of work with Microsoft valued at up to approximately $43.8 billion between September 2025 and April 2026.

The agreements run through December 2033 and do not include optional extensions.

The person familiar with Microsoft’s decision stressed that declining the additional capacity option would not alter Nscale’s reported total contract value of approximately $103 billion.

Nscale is meanwhile seeking opportunities to bring additional customers into its remaining Texas data-center capacity.

The source said the company had already held discussions with several major prospective customers about possible arrangements.

Among the potential customers is Anthropic, the developer of the Claude artificial intelligence models.

Last month, Reuters and other media organizations reported that Nscale was negotiating with Anthropic over a possible agreement to supply AI computing capacity. The potential deal could be worth approximately $45 billion.

The latest development underscores the enormous investments and commercial negotiations underway as technology companies compete to obtain the computing infrastructure needed to support artificial intelligence services.

For Nscale, attracting additional customers to use its available capacity remains an important element of its expansion strategy.

For Microsoft, the decision marks a change in its plans for securing additional computing capacity in Texas, while leaving its current agreement and disclosed financial commitments with Nscale unchanged.

Microsoft and Nscale did not respond to Reuters’ requests for comment outside business hours.
