CleanSpark Hits 50 EH/s Hashrate Milestone With 9.6% Growth

CleanSpark, a leading Bitcoin mining company, has achieved a significant operational milestone by reaching 50 exahashes per second (EH/s) in June 2025. This accomplishment marks the first time a Bitcoin miner has reached this level of operational hashrate entirely through fully self-operated infrastructure. The company's expansion across the U.S. has been instrumental in achieving this goal, demonstrating its commitment to operational efficiency and growth.

CleanSpark's average fleet efficiency improved to 16.15 joules per terahash (J/TH), a notable increase that underscores its focus on optimizing energy usage. This efficiency gain is a testament to CleanSpark's strategic investments in technology and infrastructure, which have enabled it to enhance its mining capabilities while maintaining a high level of operational performance.

In addition to its hashrate milestone, CleanSpark mined 685 bitcoins in June, selling 578 of them for over $61 million. This financial performance highlights the company's ability to generate substantial revenue from its mining operations, further solidifying its position as a leader in the Bitcoin mining industry.

CleanSpark's achievement of a 50 EH/s operational hashrate represents a 9.6% increase from the previous month. This growth is supported by the company's recent acquisition of 179 megawatts of additional power capacity, which will enable it to continue expanding its mining operations and maintaining its competitive edge in the market.

The company's success in reaching this milestone is a result of its strategic investments in technology, infrastructure, and operational efficiency. CleanSpark's ability to achieve this level of hashrate entirely through self-operated infrastructure sets it apart from its competitors and positions it as a leader in the Bitcoin mining industry. The company's focus on optimizing energy usage and expanding its operations across multiple states has enabled it to generate substantial revenue and maintain a high level of operational performance.

CleanSpark's CEO, Zach Bradford, announced the success, highlighting an industry first. COO Scott Garrison and CTO Taylor Monnig played crucial roles in the technical and operational advancements that facilitated this accomplishment. The company's expanded Bitcoin capacity is notable with treasury holdings of 12,608 BTC as of June 30, further cementing its standing globally. The company plans future growth, with an additional 179 megawatts of power capacity contracted.

Technological outcomes predict a continuation of groundbreaking milestones in Bitcoin infrastructure. Industry observers will be watching as CleanSpark moves closer to its next target of reaching 60 EH/s, marking another potential transformation in the Bitcoin mining landscape. The significant increase in energy efficiency, resulting in 16.15 J/Th, positions CleanSpark competitively. The enhanced efficiency reduces operational costs and optimizes resources, which is vital for profitability in Bitcoin mining amidst fluctuating price environments.
