Bitcoin mining giants Riot Platforms and CleanSpark experienced significant output increases in August, according to recent operational updates. Riot produced 477 BTC in August, marking a year-over-year jump of 48%, exceeding its previous output by 322 BTC during the same period. The company also sold 450 BTC worth $51.8 billion and currently holds 19,309 BTC, representing a substantial 92.7% increase over the past year. CleanSpark’s output reached 657 BTC in August, with a 37.5% surge compared to the previous year, bringing its total output to 533.5 BTC worth $60.7 million last month. CleanSpark has seen a significant rise in its Bitcoin holdings as well, currently holding 12,827 BTC – a 69.7% increase over the past year. This production jump comes despite a notable year-over-year increase in Bitcoin mining difficulty. 44.9%, pushing mining difficulty to 129.7 trillion this year from 89.5 trillion in August 2024, CoinWarz data shows. While the increased difficulty adds challenge for miners, both companies have successfully managed to achieve higher operational hash rates year-over-year. Riot’s average operational hash rate rose to 31.4 EH/s in August 2025, up from 14.5 EH/s last year, representing a substantial 116.6% jump. CleanSpark’s hashrate increased to 43.3 EH/s from 21.3 EH/s, demonstrating a 103.3% growth during the same period. The success of both companies showcases the resilience of Bitcoin mining amidst a challenging market landscape.
