Nebius appears to be building out four sites in the UK as of its June 2026 expansion announcement, which says it has committed about £1.7 billion to capacity buildout at four sites. There’s also a separate report saying Nebius is building three new UK AI infrastructure sites in addition to its first UK site launched in November 2025, which would also imply four UK sites total in that rollout.

What that means

  • Most direct answer: 4 sites.
  • Cross-check: 3 new sites + 1 existing UK site = 4 total.
  • Scope note: that figure is for the UK buildout specifically, not Nebius’ global footprint.

Context

Nebius has also been discussing broader multi-location capacity growth elsewhere, including a large Finland project and multi-location capacity tied to its Meta agreement, so its total global buildout is larger than just the UK count.

TL;DR: Nebius is building out four UK sites based on the latest public announcements.
