Nscale Faces IPO Valuation Pushback and Microsoft Deal Exit

On Monday, Oct. 19, 2026, in New York, London-based data-center developer Nscale faced fresh resistance to its initial public offering valuation targets as potential buyers pushed for a significantly lower price range amid broader market turbulence for artificial intelligence infrastructure, The Business Times reported.

Valuation Disconnect and Market Pressures

Nscale has been pursuing an initial public offering valuation of about US$30 billion, according to people familiar with the matter. However, a cohort of investors recently urged that a valuation between US$16 billion and US$19 billion would find much more favor with buyers. This valuation gap reflects growing caution across the sector as borrowing costs rise and uncertainty builds regarding the long-term financial payoff of artificial intelligence investments.

The pushback follows a series of setbacks for comparable AI infrastructure companies. CoreWeave wiped out a quarter of its market value while its credit risk climbed to an all-time high, and Nebius Group stock slumped 32 per cent over a two-week period. Bankers have faced a difficult environment that threatens to stall public debuts outside of Anthropic, as smart-ring maker Oura and Bamboo Insurance Services were forced to postpone their own market entries due to climbing interest rates and the Iran war.

Microsoft Pulls Out of UK Data Center Deal

Adding to Nscale’s near-term hurdles, investor and client Microsoft pulled out of a UK data center deal with the firm, The Business Times reported on Sunday, Oct. 18, 2026. The site in Loughton, Essex, ran into severe delays stemming from power constraints with grid connections possibly not arriving until the 2030s. Despite exiting this specific project, Microsoft remains committed to a separate Nscale project in Norway.

Construction challenges have also affected Nscale’s flagship facility in Glomfjord, Norway, just north of the Arctic Circle. Designed to run 30 megawatts, the site is currently operating at 6.4 megawatts and sits six months behind schedule following cooling-system leaks, local regulatory hurdles, and a transformer fire in December 2025. These delays have triggered customer penalties.

Regulatory Review and Contractual Backlog

Nscale publicly filed for a US listing on Sept. 18, 2026, and is currently working through comments from the US Securities and Exchange Commission (SEC). Although the required 15-day waiting period has elapsed, the firm has not yet begun formal marketing and will kick off its roadshow once SEC comments are resolved. Deliberations remain ongoing and IPO plans are subject to change.

The company’s pitch relies heavily on a large contracted backlog. Nscale reported total contracted value of roughly US$103 billion, supported by prominent agreements including a multi-year deal with Microsoft and an agreement with Anthropic signed on Aug. 25, 2026, valued at up to US$44.6 billion for 460 megawatts at the Monarch campus in West Virginia. Yet, live operating capacity currently accounts for about US$2.6 billion of that total across 55 megawatts in Europe, leaving the vast majority of contracted capacity dependent on future construction.
