2025 year-end self-mining hash rate target
Company: Cipher Mining
What the later record shows
Outcome not yet confirmed
The target was cut to ~23.0 EH/s, and hashrate reached only ~23.6 EH/s in Q4 2025. Cipher then adopted a bitcoin-mining exit strategy and decommissioned Black Pearl mining in February 2026, leaving ~11.6 EH/s.
