Insights

Bitcoin Mining Analyst

CleanSpark shows strong operational growth with 43.3 EH/s average hashrate, 12,827 BTC holdings, while maintaining strategic bitcoin accumulation despite leadership changes.

CleanSpark's August update demonstrates robust operational execution amid challenging summer conditions. The company achieved an average operating hashrate of 43.3 EH/s, representing a 1.4 EH/s month-over-month increase despite seasonal heat challenges that typically hamper mining efficiency. This hashrate growth reflects effective thermal management at their facilities.

The company mined 657 bitcoins in August (averaging 21.20 daily), while maintaining disciplined treasury management. Their 12,827 BTC treasury (including 3,026 BTC posted as collateral) positions them among the top public miners by holdings. The company strategically sold 533.5 BTC at an average price of $113,800, generating $60.7 million in liquidity.

From an infrastructure perspective, CleanSpark reports 1.03 GW under contract with 808 MW currently utilized, indicating 78.4% power utilization. This suggests room for strategic expansion without immediate capital expenditure on new facilities. Their fleet efficiency peaks at 16.07 J/Th, reflecting competitive operational efficiency compared to industry standards.

CEO Matt Schultz's comments suggest a dual strategy of continuing bitcoin accumulation while exploring "other verticals" to maximize contracted power resources. The leadership transition mentioned appears well-managed with minimal operational disruption, as evidenced by the continued hashrate growth. The company's year-to-date production of 5,296 BTC in 2025 demonstrates consistent execution in a post-halving environment where mining economics have become more challenging.

12,827 BTC in treasury, grew average hashrate by 1.4 EH/s month over month

"While August was a month of leadership transition, CleanSpark remained unwavering in its focus on operational performance and in continuing to grow our bitcoin treasury to build long-term value for all stakeholders," said Matt Schultz, CEO and Chairman.
