CleanSpark Reaches 50 EH/s Milestone

CleanSpark (CLSK) achieved a significant milestone in June, reaching 50 EH/s and expanding its operations across four U.S. states. The company improved its average fleet efficiency to 16.15 joules per terahash (J/Th).

In June, CleanSpark produced 685 BTC, bringing the year-to-date output to 3,968 BTC. All coins were self-mined, resulting in total bitcoin holdings of 12,608, positioning CleanSpark as the seventh largest publicly traded bitcoin holder, just ahead of Tesla.

The company sold 578.51 BTC for $61.2 million, achieving an average sale price of $105,860, which exceeded the volume-weighted average price for June.

CEO Zach Bradford stated, “June 2025 marked a milestone month for CleanSpark. We achieved our mid-year target of reaching 50 EH/s… through fully self-operated infrastructure.”

CleanSpark also secured contracts for an additional 179 MW of power, raising its total contracted capacity to 987 MW, which is projected to support over 10 EH/s of incremental hashrate.

Additionally, the company launched its Digital Asset Management program, which includes a spot sales strategy and derivative overlay. This initiative showed initial gains in June, reinforcing CleanSpark’s focus on optimization and operating leverage.
