Bitcoin Hashrate Reclaims 1 Zettahash Despite AI Data Center Conversions

Bitcoin's aggregate compute power has rebounded above 1 zettahash per second (1,000 EH/s) on a seven-day moving average, marking its highest operating level since March 3 ¹. The expansion comes despite large public mining firms repurposing power infrastructure and data centers for high-performance computing (HPC) and artificial intelligence workloads ¹. At the time of writing, $BTC traded at $81,082.

The computational recovery is directly tightening mining economics. The network executed a 5.92% mining difficulty increase on Oct. 16, with block production pacing toward an estimated 5.16% upward adjustment roughly seven days later ¹. This sustained network activity has wiped out the margin relief that remaining miners anticipated after public operators began offloading hardware capacity—displacing roughly $1.5 billion in hardware value alongside a 52% quarterly surge in direct HPC and AI revenues across the sector ¹.

Hardware Redistribution Absorbs Public Miner Exits

Replacement capacity is arriving through continuous self-mining additions and distributed secondary markets ¹. Bitdeer expanded its operational footprint across September, elevating self-mining capacity to 82.3 EH/s from 79.9 EH/s in August, while its co-mining segment increased to 28.7 EH/s from 21.6 EH/s—adding a combined 9.5 EH/s in a single month ¹. Bitdeer is also pursuing AI opportunities without winding down dedicated Bitcoin operations ¹.

Concurrently, displaced equipment is returning online via smaller operators capitalizing on lower power rates abroad and hosted rack space ¹. Following Core Scientific's termination of a 15 EH/s chip contract with Block and Proto Global in the second quarter—which triggered a $41.9 million recorded loss as the firm pivoted toward high-density colocation—retail hosting firms like Sazmining began advertising Proto immersion hashboards alongside secondary Antminer S21 XP units hosted in Texas and Paraguay ¹. While major publicly traded miners previously expanded their enterprise fleets, the current cycle reflects a hardware redistribution toward non-traditional and decentralized operators ¹.
