Construction of Building 1 begins. Reykjanesbær planning records from May 11 explicitly state that the next construction phase of KEF301 was under construction by May 2023, so we model it as starting by the beginning of the month as a conservative estimate.

Nscale's GPU fit-out begins at the datacenter owned by Verne in Keflavik, Iceland. Estimated from Verne's statement that the first 7.5 MW deployment was completed in approximately three months; the exact start date was not disclosed.

First Nscale AI capacity operational. Verne reports the first 7.5 MW of Nscale capacity deployed with 128 racks, including 64 liquid-cooled NVIDIA GB300 racks. The AI capacity is assumed to be in the southernmost white building because it is the newest major data hall, has roughly 16 MW of capacity, and was the hall still being expanded most recently before Nscale's deployment; however, Verne and Nscale have not publicly confirmed the building assignment.

64-rack NVIDIA GB300 NVL72 cluster confirmed in production. Nscale reports that production benchmarking was performed during June across all 64 racks. Month-end is used because the exact benchmark date was not disclosed.

Building 1 is operational (estimate). Full campus visibly externally complete from satellite imagery. Virtually no active construction visible.
