CleanSpark Hits 50 EH/s Milestone, Ranks Among Top Public Bitcoin Holders

CleanSpark (CLSK) marked significant progress in June, reaching a computing power milestone of 50 exahashes per second (EH/s) while expanding operations across four U.S. states. The company also boosted its mining fleet’s average efficiency to 16.15 joules per terahash (J/Th).

The Las Vegas-based bitcoin miner produced 685 BTC last month, pushing its year-to-date total to 3,968 BTC. All coins were mined in-house, bringing CleanSpark’s bitcoin holdings to 12,608 BTC—a figure that now places it seventh among publicly traded bitcoin holders, just ahead of Tesla.

During June, CleanSpark sold 578.51 BTC for proceeds of $61.2 million, achieving an average sale price of $105,860, which surpassed the month’s volume-weighted average price.

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

The company also announced new contracts securing an additional 179 megawatts (MW) of power capacity, bringing its total contracted capacity to 987 MW. This added power is expected to support over 10 EH/s of future mining hashrate growth.

In parallel, CleanSpark launched its Digital Asset Management program, integrating spot sales and derivatives strategies. The initiative began delivering positive results in June, aligning with the company’s broader push for operational efficiency and greater leverage in its mining operations.
