Publicly traded bitcoin miners CleanSpark, BitFuFu, and Canaan all reported lower bitcoin production in June compared to May, though the reasons varied. CleanSpark mined 614 BTC, down from 671 in May, as its average operating hashrate fell from 46 EH/s to 43 EH/s. The company ended June with 13,924 bitcoin, making it the 11th-largest publicly traded holder. BitFuFu produced 125 BTC, a 29% decline from 177 the previous month, with total hashrate slipping from 19.5 EH/s to 15 EH/s. The firm attributed the drop to lower managed hashrate but noted expansion milestones, deploying 1,200 S21 XP miners and securing 5.3 EH/s of contracted hashrate starting August. Canaan mined 64 BTC, also a 29% fall from 90 in May, partly due to power grid maintenance at one of its sites. Its Texas joint venture recovered from wildfire disruptions. Canaan added 49 BTC to its treasury, ending with a record 1,915 BTC and 3,953.2 ETH.
The weaker production occurred even as bitcoin mining difficulty dropped more than 10% in mid-June to its lowest level of 2026, the second-largest downward adjustment this year. Meanwhile, bitcoin (BTC) recovered to over $64,200 after touching $57,800 near the end of June, a near two-year low. Stock reactions diverged: CleanSpark (CLSK) rose 7.7% to $13.30, fueled by a separate $6.6 billion AI data center lease announcement; BitFuFu (FUFU) gained 6% to $1.42; and Canaan (CAN) fell 1.5% to $0.30.
