Publicly traded bitcoin miners CleanSpark, BitFuFu and Canaan reported lower bitcoin production in June compared with the prior month, though the declines stemmed from different operational factors.
CleanSpark mined 614 bitcoins during June, down from 671 in May. BitFuFu produced 125 bitcoins compared with 177 the previous month, while Canaan mined 64 bitcoins versus 90 in May.
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 (FUFU) gained 6% to $1.42, while Canaan (CAN) fell 1.5% to $0.30.
The weaker production reports came despite bitcoin mining difficulty dropping more than 10% in mid-June to its lowest level of 2026. It was the second-largest downward adjustment of the year, reducing the computational power needed to mine new blocks.
Meanwhile, 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.
