CleanSpark Inc. has achieved a significant milestone, reaching its mid-year target of 50 exahashes per second (EH/s) in operational hashrate.
The company is the first publicly traded Bitcoin miner to hit this mark using fully self-managed infrastructure, with operations spanning four U.S. states.
This achievement was detailed in the company’s June 2025 mining update, which reported a 9.6% month-over-month increase in hashrate. The expansion was supported by an additional 179 megawatts of contracted power—sufficient to add another 10 EH/s in the near term. CleanSpark attributed the progress to its energy-efficient fleet, which now operates at an average efficiency of 16.15 joules per terahash (J/Th), and to the execution of its operations, engineering, and technology teams.
In terms of production, June yielded 685 BTC, with an average daily output of 22.82 BTC. This brings the company’s year-to-date total to 3,968 BTC. All coins have been self-mined, growing CleanSpark’s Bitcoin treasury to 12,608 BTC, ranking it seventh globally among publicly listed firms, according to BitcoinTreasuries.net.
Building on this momentum, CleanSpark has also launched a Digital Asset Management division. The initiative has already delivered early success, with 578.5 BTC sold in June for $61.2 million. The average sale price was $105,860 per bitcoin, $446 above the volume-weighted average price (VWAP) for the period, excluding additional premiums earned from derivative strategies.
Commenting on the milestone, CEO Zach Bradford highlighted the company’s infrastructure-first approach as a strategic advantage.
“We invested in power and data center capacity, not just the coin,”
he said.
“Now, we’re entering a new phase of optimization, disciplined growth, and long-term value creation for our shareholders.”
Meanwhile, CleanSpark’s May 2025 performance had already signaled its aggressive trajectory toward the 50 EH/s benchmark, reinforcing its status as a leading force in vertically integrated Bitcoin mining.
