Bitcoin mining profitability fell by over 7% in September 2025, investment bank Jefferies reports, citing increased network hashrate and a slight dip in BTC prices as primary factors.
Bitcoin mining profitability's decline highlights the challenges miners face due to rising hashrate and price fluctuations. Immediate concerns focus on lower earnings, impacting major firms like Marathon and CleanSpark. Bitcoin mining earnings saw notable reductions in terms of profitability, according to Jefferies. Analysts attributed the more than <a href="bitcoin-mining-profitability-september-decline" rel="noopener noreferrer nofollow">7% decline in September</a> chiefly to an increased network hashrate and decreased BTC prices. Key industry players were affected; Marathon Digital Holdings led mining production, though their output still fell compared to August. CleanSpark also encountered similar circumstances as the network hashrate climbed 9%. The increased hashrate put pressure on earnings as the mining industry experienced a shake-up. Lower revenue was felt among companies, such as Marathon and other North American miners, who faced increased costs without parallel gains. Financial markets had mixed reactions, with Jefferies adjusting price targets for entities like Galaxy Digital and Marathon. Analysts maintained a cautious outlook on sector stability, given the current revenue squeeze from rising network challenges.
