Microsoft has ended an agreement tied to a data center project in Loughton, Essex, a move that affects one of British cloud provider Nscale's key customer relationships. The reported withdrawal comes weeks after Nscale filed for a U.S. initial public offering naming Microsoft and Anthropic as expected major customers.
Highlights
- Microsoft terminated its agreement for the Loughton, Essex data center with Nscale, one of Nscale's two largest customers, according to the Telegraph.
- Nscale, which filed for a U.S. IPO last month and counts Anthropic as a major customer, reported total contracted value grew from $100 million to over $103 billion in 2.5 years.
- Microsoft's exit may heighten investor focus on Nscale's customer concentration and execution risks as it competes with CoreWeave, Nebius, Crusoe, and Lambda in the rapidly growing AI infrastructure market.
Deal termination and IPO context
As reported by Reuters, citing Britain's Telegraph newspaper, Microsoft recently terminated its agreement for the Loughton, Essex, data center with Nscale, one of the British group's two largest customers.The report does not specify why Microsoft withdrew from the project. Microsoft and Nscale do not immediately respond to Reuters requests for comment outside regular business hours.
Nscale filed for a U.S. initial public offering last month, and its prospectus says Microsoft and Anthropic are expected to be its major customers. The company provides infrastructure including compute, power and data centers, alongside software used to train and run AI models.
Implications for the UK AI infrastructure market
Nscale operates in a fast-expanding AI infrastructure segment, competing with CoreWeave, Nebius, Crusoe and Lambda. The company is backed by Nvidia and has been positioning itself to capture demand for compute-heavy AI workloads.Its prospectus says the business has expanded rapidly since launch, scaling from $100 million to more than $103 billion in total contracted value in two-and-a-half years. Microsoft's exit from one project could draw investor attention to customer concentration and execution risks as Nscale pursues its U.S. listing.
Our earlier article on the US AI data center boom highlighted how surging buildouts are increasingly running into higher financing costs, construction delays, and power constraints. We noted that a meaningful share of planned projects is being questioned or pushed back, while cost overruns and tighter funding conditions are testing investor confidence in large-scale AI infrastructure plans.
