Publicly traded bitcoin miners CleanSpark, BitFuFu and Canaan reported lower bitcoin production in June compared with the prior month. CleanSpark mined 614 bitcoins during June, down from 671 in May, while BitFuFu produced 125 bitcoins compared with 177 the previous month and Canaan mined 64 bitcoins versus 90 in May. The declines stemmed from different operational factors including lower managed hashrate, power grid maintenance, and facility disruptions. Bitcoin mining difficulty dropped more than 10% in mid-June to its lowest level of 2026, representing the second-largest downward adjustment of the year. This reduced the computational power needed to mine new blocks, though production remained softer across the three companies despite the easier mining conditions.
CleanSpark Reports 9% Production Decline with 614 Bitcoin Mined
CleanSpark's monthly bitcoin output fell about 9% while its average operating hashrate dropped from 46 exahash per second (EH/s) in May to roughly 43 EH/s in June. The company closed June with 13,924 bitcoin, making it the 11th-largest publicly traded bitcoin holder. Shares of CleanSpark (CLSK) climbed 7.7% to $13.30 on Tuesday, mostly driven by the company's separate announcement of a $6.6 billion, 20-year lease for its Sandersville, Georgia, AI data center campus.
BitFuFu Production Drops 29% While Expanding Self-Owned Fleet
BitFuFu's production dropped around 29% while its total hashrate dipped from May's 19.5 EH/s to 15 EH/s in June. The company said the drop primarily reflected lower managed hashrate, though it continued to expand its self-owned fleet, increasing self-owned hashrate to 3.5 EH/s after deploying 1,200 additional S21 XP miners during the month. It also signed agreements to deploy another 2,000 rigs in July and secured 5.3 EH/s of contracted hashrate starting in August. Shares of BitFuFu (FUFU) gained 6% to $1.42.
Canaan Mining Output Falls 29% Amid Power Grid Maintenance
Canaan also saw production fall about 29%, which it partly attributed to power grid maintenance at one of its mining sites. Meanwhile, its Texas joint venture recovered from wildfire disruptions that bogged down production in May. Canaan also added 49 bitcoin to its treasury, ending June with a record 1,915 BTC alongside 3,9532 ETH. Shares of Canaan (CAN) fell 1.5% to $0.30.
Bitcoin Price Recovers to Over $64,200 After June Dip
Bitcoin (BTC) recovered to over $64,200 after falling to roughly $57,800 near the end of June, its lowest level in nearly two years. The weaker production reports came despite bitcoin mining difficulty dropping more than 10% in mid-June to its lowest level of 2026, the second-largest downward adjustment of the year.
