CleanSpark And BitFuFu Post Lower Bitcoin Output In September

Bitcoin production fell across several major mining operations in September, according to recent operational updates from CleanSpark, BitFuFu, and Canaan. CleanSpark reported a nearly 11% drop in output, mining 529 BTC during the month compared to 593 BTC in August. The company disclosed sales of 2 BTC on spot markets and 700 BTC through call option exercises at an average price of $72,928 per Bitcoin, exceeding its monthly production by 173 BTC and bringing its month-end treasury down to 13,530 BTC. Alongside the figures, CleanSpark announced it will transition from monthly mining updates to quarterly reporting as it expands its data center operations.

BitFuFu reported a 4% decline in September production to 167 BTC, down from 174 BTC in August. While its self-mining output rose over 11% to 98 BTC, cloud mining production fell nearly 20% to 69 BTC. BitFuFu also noted ongoing uncertainty regarding its proposed majority stake acquisition in an Ethiopian mining facility, citing unresolved conditions and a recent electricity supplier notice threatening collateral seizure over disputed payments. Meanwhile, Canaan maintained its output at 44 BTC, matching its August total and halting three consecutive months of declines. The company brought its 8-megawatt Nordic district heating project fully online and continued executing its treasury-funded repurchase initiative.
