The trick: Announced Not Shipped
Nscale promised Britain's largest AI supercomputer in Essex, 23,040 chips by early 2027.
The grid says full power comes in the 2030s, and its only publicly announced customer, Microsoft, has walked.

Loughton will be the UK's largest AI supercomputer, with 23,040 GB300 GPUs delivered in Q1 of 2027.
