Portfolio capacity ~927 MW in 2025
Company: Cipher Mining
What the later record shows
Partly delivered
In 2025, operating capacity grew to 477 MW with Black Pearl Phase I. The other ~450 MW was still under development, and the HPC leases for it have deliveries beginning in 2026. It is unclear whether '~927 MW' meant operating capacity or total portfolio capacity.
