CleanSpark Hits 50 EH/s Milestone, Surpasses Tesla in Bitcoin Holdings

CleanSpark (NASDAQ: CLSK), a leading U.S. bitcoin mining company based in Las Vegas, reached a major milestone in June 2025 by achieving 50 exahashes per second (EH/s) in total hashrate capacity. This achievement stems from its expansion across four U.S. states and significant upgrades in mining efficiency, with its average fleet performance improving to 16.15 joules per terahash (J/Th).

In June alone, CleanSpark mined 685 BTC, bringing its year-to-date production to 3,968 BTC — all self-mined. The company’s total bitcoin holdings now stand at 12,608 BTC, positioning it as the seventh-largest public bitcoin holder, surpassing Tesla.

To support operational growth, CleanSpark secured contracts for an additional 179 megawatts (MW) of power, increasing its total contracted capacity to 987 MW. This new energy infrastructure is expected to support over 10 EH/s of incremental hashrate, reinforcing the company's aggressive growth trajectory in the bitcoin mining industry.

The company also reported the sale of 578.51 BTC in June for $61.2 million, averaging $105,860 per bitcoin — outperforming the month’s volume-weighted average price. This performance reflects CleanSpark’s enhanced digital asset management strategy, which integrates spot sales and a derivative overlay to maximize returns.

CEO Zach Bradford highlighted the significance of the June milestone, stating the company met its mid-year target entirely through self-operated infrastructure, underlining CleanSpark's strategic focus on vertical integration and operational efficiency.

As regulatory clarity improves and institutional demand rises, CleanSpark continues to strengthen its position as a top-tier bitcoin miner with scalable infrastructure and robust treasury management — solidifying its role in the evolving digital asset landscape.
