Fourteen months separate the last bitcoin mined at Black Pearl from the first capacity Amazon Web Services took delivery of there. The 75-acre site near Wink, in Winkler County, energised and began hashing on 23 June 2025 with 150 MW in its first phase at about 2.5 exahash per second; mining stopped in February 2026, and in November 2025 Cipher signed a fifteen-year lease of roughly 300 MW gross to AWS worth about $5.5 billion. The first data centre capacity was handed over in August 2026 with rent commencing, two months ahead of schedule at the tenant's request. Interconnection is 300 MW gross approved, with ERCOT market participation agreements executed. The AWS build takes both air and liquid cooling to the racks and was assembled from off-site modules - Cipher delivered the original mining plant here in sixteen months. Ownership sits with Cipher Digital Inc., the Nasdaq-listed company that dropped Mining from its name in the fourth quarter of 2025, through the subsidiary Cipher Black Pearl LLC.
