CleanSpark (CLSK) reached the 50 EH/s milestone in June, expanding operations across four U.S. states and improving average fleet efficiency to 16.15 joules per terahash (J/Th).
The Las Vegas-based firm produced 685 BTC last month, bringing its year-to-date output to 3,968 BTC. All coins were self-mined, and total bitcoin holdings reached 12,608, ranking the company seventh among publicly traded bitcoin holders, one spot ahead of Tesla.
CleanSpark sold 578.51 BTC for $61.2 million, with an average sale price of $105,860, outpacing the volume-weighted average price for the month.
“June 2025 marked a milestone month for CleanSpark,” said CEO Zach Bradford. “We achieved our mid-year target of reaching 50 EH/s… through fully self-operated infrastructure.”
The company secured contracts for an additional 179 megawatts (MW) of power, raising its total contracted capacity to 987 MW. The new capacity is expected to support more than 10 EH/s of incremental hashrate.
CleanSpark also launched its Digital Asset Management program, which includes a spot sales strategy and derivative overlay. The initiative showed initial gains in June, supporting the company’s broader focus on optimization and operating leverage.
