Publicly traded Bitcoin miners are reducing mining capability sooner than the Bitcoin community general, suggesting that extra operators are redirecting electrical energy and infrastructure towards knowledge facilities and high-performance computing (HPC), in one other signal of the sector’s evolution past creating extra crypto.
Within the newest Miner Weekly publication, BlocksBridge Consulting reported that realized hashrate amongst a cohort of public Bitcoin miners fell from 368.3 exahashes per second (EH/s) within the fourth quarter of 2025 to 319 EH/s within the second quarter of 2026, a 13.4% decline.
The contraction was even sharper when excluding Bitdeer, which continued to broaden its mining operations. With out Bitdeer, the cohort’s realized hashrate fell 21.2% over the six-month interval, from 324.6 EH/s to 255.9 EH/s. Bitdeer’s realized hashrate, in the meantime, elevated 44% to 63 EH/s.
By comparability, the Bitcoin community’s common hashrate declined 10.6% over the identical interval.
The shift comes as extra miners report a rising share of income from non-mining actions. Core Scientific generated $136.7 million in colocation income throughout the second quarter, in contrast with simply $27.5 million from Bitcoin mining. TeraWulf reported $31.9 million in HPC lease income, in contrast with $12.8 million from mining.
Core Scientific and TeraWulf are actually producing nearly all of their income from non-mining actions.

Riot Platforms and Bitdeer stay a lot earlier within the transition, with Bitcoin mining persevering with to account for the overwhelming majority of their income in the latest quarter.

Unwinding post-China mining increase
BlocksBridge framed the present pullback as an unwinding of the growth cycle that adopted China’s Bitcoin mining ban in 2021, which triggered one of many sharpest declines in community hashrate earlier than a speedy restoration as miners relocated abroad.
In North America, that migration helped gas an growth amongst public miners, which raised capital and bought new energy websites to broaden their operations.
One halving cycle later, the economics have shifted considerably. Weaker mining profitability, coupled with surging demand for AI infrastructure since 2022, has prompted a number of public miners to repurpose websites and energy capability away from Bitcoin mining fully.
