70 MW Nvidia GB300 building on track for Q2 2026 delivery
Company: Core Scientific - Project: Muskogee
What the later record shows
Delivered; the record does not say when
The Q2 2026 earnings deck's CoreWeave status table shows Muskogee's ~70 MW billing as of mid-July 2026, so the building was handed over. No passage says whether that happened by June 30 or in early July. The August 18 news article only repeats the earlier expectation.
