Microsoft has cancelled its deal with Nscale to serve as anchor tenant and lease 23,000 Nvidia AI chips for a delayed Essex data centre, threatening the project's multibillion‑dollar listing.
Microsoft has pulled out of its planned partnership with British cloud provider Nscale, ending a deal that would have made the U.S. tech giant the anchor tenant of Nscale’s first UK data centre in Loughton, Essex. The agreement, reported by the Telegraph, would have seen Microsoft rent roughly 23,000 Nvidia AI chips for the facility, but repeated delays to connect the site to the national grid have prompted the cancellation.
The move is a major blow to Nscale, whose £2 billion, 1‑gigawatt Loughton project was positioned as a cornerstone of a forthcoming $35 billion initial public offering. Analysts note that Microsoft’s withdrawal threatens up to 85 % of the total contract value that Nscale had counted on, leaving only a small fraction of the centre’s capacity – about 3 % – currently operational. The setback also raises questions about the viability of the company’s $3.36 billion pre‑IPO financing, which hinges on securing large‑scale, long‑term customers.
Beyond Nscale’s immediate fortunes, the cancellation underscores broader challenges in scaling AI infrastructure in the UK. Grid‑power delays, now projected to extend into the 2030s, are forcing cloud operators to reassess timelines and capital commitments. For Microsoft, the loss of a dedicated European AI‑compute hub may accelerate its search for alternative sites or partnerships that can deliver power and connectivity on a faster schedule.
Stakeholders will be watching Nscale’s next steps closely: whether the firm can replace Microsoft with other anchor tenants, how it will adjust its IPO timeline, and if the UK government or energy providers can resolve the grid bottleneck. The outcome will shape both the UK’s AI data‑centre landscape and the broader race to secure massive compute capacity for next‑generation models.
