According to CryptoQuant data published on October 22, 2026, Bitcoin’s True Hashrate reached 1,000 EH/s, or 1 ZH/s, approaching the historical highs recorded in late 2025. This growth pushed mining difficulty to a record 140.58 T following a 5.92% increase on October 16, with another rise of 4% to 6% expected at the end of the month. Companies listed in the United States now control 35% to 40% of global hashrate, backed by traditional financial institutions and the partial integration of their data center infrastructure with artificial intelligence workloads. With Bitcoin trading between $80,000 and $83,000 and a hashprice of about $37 per PH per day, only miners using 9–12 J/TH ASIC equipment and paying less than $0.08–$0.10 per kWh remain profitable. This expansion represents an indirect institutional bullish signal, but a deep market correction could weaken the sector before the next halving scheduled for April 2028.
