Riot and CleanSpark Boost Bitcoin Output in August
In August 2025, Bitcoin miners Riot Platforms and CleanSpark reported strong growth in BTC production and hashrate despite soaring mining difficulty.
Bitcoin output rises for leading U.S. miners
Bitcoin mining companies Riot Platforms and CleanSpark recorded significant production growth in August 2025. Riot mined 477 BTC, a 48% increase year-over-year, while selling 450 coins worth $51.8 million. Its total reserves grew to 19,309 BTC, up 92.7% from last year.
CleanSpark achieved even stronger results, producing 657 BTC compared to 478 BTC in August 2024, a 37.5% jump. The company sold 533.5 BTC for $60.7 million and now holds 12,827 BTC, a 69.7% increase year-over-year.
Bitcoin network mining difficulty rose 44.9% over the past year to 129.7 trillion. Despite this challenge, Riot’s hashrate reached 31.4 EH/s, up from 14.5 EH/s a year earlier. CleanSpark expanded to 43.3 EH/s from 21.3 EH/s, doubling its operational capacity.
Miners explore diversification
The industry is adapting as higher difficulty squeezes margins. Hut 8 is building four U.S. data centers for high-performance computing, including artificial intelligence workloads. Riot, Hive Digital Technologies, and Iren are also pivoting toward AI integration.
These moves highlight how leading miners not only grow Bitcoin production but also diversify to secure long-term profitability in an evolving market.
