Bitcoin Hashrate Down 19% in Longest-Ever Slide as Miners Shift Power to AI

According to BeInCrypto, Bitcoin’s 30-day average hashrate has dropped 19% since November 2025, sliding from 1,108 EH/s to 898 EH/s. Glassnode data shows the nine-month decline is the longest sustained drawdown in the network’s history. The slide coincides with the largest capital migration ever recorded among mining companies. Miners currently hold more than $70 billion in AI contracts. Some electricity capacity originally used for bitcoin mining has been shifted to AI hosting, and that capacity may be difficult to bring back to the Bitcoin network. The report ties the hashrate decline to this corporate shift. It cites Glassnode’s historical data to describe the nine-month stretch as unprecedented. The starting hashrate was 1,108 EH/s, and the latest reading is 898 EH/s, a 19% reduction. The AI contract holdings among miners exceed $70 billion. A portion of power capacity has moved away from bitcoin mining into AI hosting. Whether that capacity returns remains uncertain, according to the report.
