Public Bitcoin miners cut hashrate 13.4% as AI infrastructure revenue grows

Latest NewsPublishedAug 13, 2026

AI and HPC are reshaping mining economics as operators repurpose power and data centers, while a smaller group of miners continues to expand Bitcoin capacity.

Publicly traded Bitcoin miners are cutting mining capacity faster than the Bitcoin network overall, suggesting that more operators are redirecting electricity and infrastructure toward data centers and high-performance computing (HPC), in another sign of the sector’s evolution beyond creating more crypto.

In the latest Miner Weekly newsletter, BlocksBridge Consulting reported that realized hashrate among a cohort of public Bitcoin miners fell from 368.3 exahashes per second (EH/s) in the fourth quarter of 2025 to 319 EH/s in the second quarter of 2026, a 13.4% decline.

The contraction was even sharper when excluding Bitdeer, which continued to expand its mining operations. Without Bitdeer, the cohort’s realized hashrate fell 21.2% over the six-month period, from 324.6 EH/s to 255.9 EH/s. Bitdeer’s realized hashrate, meanwhile, increased 44% to 63 EH/s.

By comparison, the Bitcoin network’s average hashrate declined 10.6% over the same period.

The shift comes as more miners report a growing share of revenue from non-mining activities. Core Scientific generated $136.7 million in colocation revenue during the second quarter, compared with just $27.5 million from Bitcoin mining. TeraWulf reported $31.9 million in HPC lease revenue, compared with $12.8 million from mining.

Riot Platforms and Bitdeer remain much earlier in the transition, with Bitcoin mining continuing to account for the vast majority of their revenue in the most recent quarter.

Unwinding post-China mining boom

BlocksBridge framed the current pullback as an unwinding of the expansion cycle that followed China’s Bitcoin mining ban in 2021, which triggered one of the sharpest declines in network hashrate before a rapid recovery as miners relocated overseas.

In North America, that migration helped fuel an expansion among public miners, which raised capital and acquired new power sites to expand their operations. 

One halving cycle later, the economics have shifted significantly. Weaker mining profitability, coupled with surging demand for AI infrastructure since 2022, has prompted several public miners to repurpose sites and power capacity away from Bitcoin mining entirely.
