Microsoft Cancels Nscale Loughton Project, Putting U.S. IPO in Doubt

Investor resistance to Nscale’s $30 billion target along with SEC questions and build problems increase the chance the company will delay or reprice its US listing.

Overview

  • Sunday reports said Microsoft terminated its Loughton, Essex cooperation with Nscale, removing one of the developer’s largest listed customers and weakening the IPO narrative.
  • Nscale filed a US registration on Sept. 18 and is still answering SEC comments and has not begun a formal roadshow, leaving timing of the offering unsettled.
  • Multiple investors told reporters the company’s roughly $30 billion valuation target faces pushback and that a $16–19 billion range would be easier to place.
  • Nscale’s flagship builds have suffered serious problems, including cooling‑system leaks, regulatory delays and a fire at its Norway site, which slowed project timelines by months.
  • The company retains $3.36 billion in fresh pre‑IPO backing from investors such as Third Point and Nvidia, but cooling markets for AI infrastructure and peer share drops heighten the risk of a delayed or downsized IPO and could squeeze customers, workers and local supply chains.
