Key Highlights

  • Microsoft (NASDAQ:MSFT) has pulled out of a UK data centre deal with Nscale, according to a Telegraph report cited by Bloomberg on Sunday, October 18, 2026, which Microsoft had not been reported as confirming.
  • The reported exit is a setback for Nscale, a UK-based AI infrastructure developer, coming weeks after it filed for a US initial public offering and needed anchor tenants to support its story.
  • Two days earlier, on Friday, October 16, Microsoft signed a 20-year agreement with NiSource for 1,100 MW of power for an Indiana data centre campus, a sign that US capacity is still growing.
  • The report relies on one newspaper's sourcing and the deal terms were not disclosed, so the reasons for the exit and its financial size remain unconfirmed.

A Reported Exit in the UK

Microsoft (NASDAQ:MSFT) has scrapped a UK data centre agreement with Nscale, Bloomberg reported on Sunday, October 18, 2026, citing The Telegraph. Nscale builds and operates AI computing capacity, and the report described the move as a blow weeks after the company filed for a US listing. The size of the agreement and Microsoft's stated reasons were not available in the material reviewed for this article. The reported exit contrasts with fresh commitments in the US. On Friday, October 16, NiSource (NYSE:NI) said it had signed a 20-year agreement to supply 1,100 MW, enough for a large AI campus, to a Microsoft data centre development in Indiana. Microsoft shares fell to about USD 525 after failing at USD 550, according to FX Leaders.

How Hyperscalers Reallocate AI Capacity

Large cloud providers such as Microsoft (NASDAQ:MSFT) secure AI capacity in two ways: building their own data centres and leasing capacity from specialists such as Nscale or CoreWeave (NASDAQ:CRWV). Leasing is faster but leaves the provider dependent on a partner's financing and construction. Owning is slower but gives control over power, the scarcest input. Power cost and availability differ sharply between countries, and a long-term US power contract can make domestic sites more attractive than leased capacity abroad. Whether that drove this decision is an inference, not a reported reason. For a developer preparing to list, losing a marquee tenant can weaken the revenue visibility that public investors pay for.

Risks and What to Watch

The first risk is confirmation: until Microsoft or Nscale comments, the scope and cause of the reported exit remain uncertain. The second is read-across, because investors already worried about AI debt may treat any cancelled lease as a sign of slowing demand, even if the capacity is moved elsewhere. The third is regulation, since the shares have also faced UK regulatory scrutiny. Investors should watch for statements from either company, any change to the Nscale listing plans and Microsoft results on Wednesday, October 28, 2026. That report will show capital spending and cloud growth, and one Motley Fool analysis expects it to be the first to give Azure revenue in dollars.

Where Things Stand

The answer is that Microsoft appears to be shifting where it sources AI capacity rather than cutting it, with a large US power deal arriving days before the reported UK exit. Microsoft (NASDAQ:MSFT) has not been reported as confirming the Nscale decision, so its reasons remain open. The next catalysts are any company statements and the quarterly results on Wednesday, October 28, 2026, alongside the Federal Reserve decision that day. The report is unconfirmed, and this is not investment advice.
