June bitcoin production falls at CleanSpark, BitFuFu and Canaan

Public bitcoin miners reported lower June output even as network mining difficulty fell by more than 10%, with company-specific hashrate declines and site maintenance weighing on production.

Fact Check
CleanSpark's official operational update confirms 614 BTC in June 2026 (Crypto Briefing notes this is down from 671 in May). Canaan's June update confirms 64 BTC (down from 90). The Block and Crypto Briefing both confirm BitFuFu also reported lower June production. The Block explicitly attributes declines to grid maintenance and hashrate changes, matching the claim's stated drivers of site maintenance and company-specific hashrate declines. The claim is corroborated by primary company disclosures and multiple independent news outlets.
Summary

June bitcoin production slowed at publicly traded miners CleanSpark, BitFuFu and Canaan even after Bitcoin network mining difficulty was cut by more than 10% in mid-June to its lowest level this year. CleanSpark mined 614 BTC in June, down from 671 BTC in May, as its average operating hashrate fell to about 43 EH/s from 46 EH/s. BitFuFu's production dropped to 125 BTC from 177 BTC as its total hashrate declined to 15 EH/s from 19.5 EH/s, despite its self-owned hashrate increasing to 3.5 EH/s because hosted hashrate fell. Canaan's output decreased to 64 BTC from 90 BTC after power-grid maintenance at some mining sites affected production. The data highlights how company-level operating issues and equipment utilization can outweigh more favorable network conditions in the post-halving mining environment.

Terms & Concepts
  • mining difficulty: A Bitcoin network setting that adjusts how hard it is for miners to produce new blocks.
  • hashrate: A measure of the computing power deployed to mine bitcoin and process network activity.
  • halving: A scheduled Bitcoin event that reduces the block reward paid to miners by half.
