Self-mining hash rate target for end of 2025
Company: Cipher Mining
What the later record shows
The date slipped
Cipher's total operating hashrate for Q4 2025 was ~23.6 EH/s, short of the ~25.1 EH/s target, though that chart may count the JV sites at their full ~4.4 EH/s rather than Cipher's share. No new date was given, and Cipher then moved to exit bitcoin mining, with hashrate falling to ~11.6 EH/s.
