CleanSpark, Inc. (CLSK), a leading Bitcoin miner in the United States, announced a historic achievement by reaching an operational hashrate of 50 exahashes per second (EH/s) in June 2025. This marks the first time a Bitcoin miner has achieved such a milestone using fully self-operated infrastructure. The company experienced a 9.6% increase in month-over-month hashrate, demonstrating robust performance and strategic growth execution.
In addition to its operational success, CleanSpark's fleet efficiency improved to 16.15 joules per terahash (J/Th), indicating optimized energy usage. As of June 30, 2025, CleanSpark boasts a treasury of 12,608 Bitcoin (BTC), ranking them seventh among publicly traded companies worldwide in Bitcoin holdings. Notably, all BTC are self-mined, showcasing the company's vertical integration strategy, distinguishing it from competitors purchasing Bitcoin on open markets.
CleanSpark further enhanced its growth potential by securing 179 megawatts (MW) of additional power capacity under contract, paving the way for over 10 EH/s of incremental hashrate expansion. This strategic move aligns with the company's plan to bolster sustainable growth and improve operational leverage. Furthermore, CleanSpark's Digital Asset Management program successfully sold Bitcoin at an average price of $105,860, surpassing the Volume Weighted Average Price (VWAP) by $446, highlighting effective treasury management practices.
The company's commitment to infrastructure investment over market Bitcoin acquisition is evident, as CleanSpark has contracted 987 MW of power, with 808 MW currently in use. This strategy not only provides immediate optimization opportunities but also secures long-term scalability and geographic diversification, promising reduced operational risks and competitive production costs in a post-halving environment.
CleanSpark's progress reflects a proactive approach towards capital efficiency and operational excellence, positioning them favorably in the expanding Bitcoin mining market. As corporates increasingly adopt Bitcoin for their balance sheets, CleanSpark's strategic positioning aims to capitalize on this trend, promising sustained shareholder value.
