Microsoft Exits UK Nscale Data Center Contract, Pressuring Latter's IPO
nashnova research
Microsoft has pulled out of a data-centre lease with UK cloud-compute firm Nscale in Essex. With Microsoft and Anthropic accounting for roughly 85% of Nscale's contracted revenue, the exit throws the company's imminent IPO into doubt.
Why did Microsoft walk away?
Microsoft was set to be the anchor tenant — the first major client to sign a long-term lease and underwrite the project's revenue base — at Nscale's debut UK data centre in Loughton, Essex.
The specific reason was not disclosed, but the project has been dogged by delays: local authorities told Nscale that grid power may not arrive until the 2030s.
This means → the issue is not a commercial disagreement but a fundamental infrastructure gap — no electricity, no data centre.
How fragile is the revenue structure?
Nscale's IPO filings show that Microsoft and Anthropic together account for about 85% of its contracted revenue.
With Microsoft out, one of only two revenue pillars is gone.
In plain terms = a company that draws nearly nine-tenths of its income from two clients just lost one of them — investors will inevitably revisit the numbers.
What does Nscale say?
A spokesperson said the company's "commitment to the Loughton site and the UK market is unchanged" and that it is exploring alternative power sources and other UK expansion sites.
Nscale added that its relationship with Microsoft "remains strong and long-term," and the London grid issue does not affect other contracts.
Yet Nscale's flagship Norway site is also behind schedule: a planned 30 MW facility currently has only 6.4 MW operational, roughly six months late.
This reflects a systemic delivery risk — multiple sites falling behind target simultaneously, not just a one-off setback.
What is happening to the broader cloud-compute sector?
Peer company CoreWeave saw its stock drop 25% in a single week, its steepest weekly fall since November last year.
Australian data-centre firm Firmus withdrew its IPO after subscriptions fell short.
This means → investors are collectively reassessing the valuation logic of the AI compute supply chain — whether Nscale can close its IPO in this window is itself a stress test of confidence in the sector.
