Hashrate target ~35.0 EH/s by year-end 2025
Company: Cipher Mining
What the later record shows
Outcome not yet confirmed
Self-mining hashrate was ~23.6 EH/s in Q4 2025, not ~35 EH/s. Cipher then adopted a bitcoin mining exit strategy, decommissioned Black Pearl mining, and cut hashrate to ~11.6 EH/s.
