Three Mining Companies Reduced Bitcoin Production in June

CleanSpark, BitFuFu, and Canaan reported a decline in Bitcoin production for June, despite mining difficulty dropping to its lowest level since 2026.

CleanSpark produced 614 BTC, down from 671 BTC in May. BitFuFu's output fell from 177 BTC to 125 BTC. Canaan mined 64 BTC, down from 90 BTC the previous month.

The decline in CleanSpark's production was attributed to a drop in average operational hash rate, the company noted. Over the month, the hash rate fell from 46 EH/s to 43 EH/s. By the end of June, the miner held 13,924 BTC.

BitFuFu's total computational power dropped from 19.5 EH/s to 15 EH/s due to a reduction in leased capacity. However, the company continued to expand its own fleet, deploying 1,200 additional S21 XP miners in June, increasing its hash rate to 3.5 EH/s. In July, it plans to add another 2,000 devices.

Canaan linked its production decline to maintenance on the power grid at one of its sites. Meanwhile, its Texas joint venture recovered from disruptions caused by wildfires in May. The miner added 49 BTC to its balance, ending June with a record 1,915 BTC and 3,952 ETH.

The companies' stocks reacted differently. CleanSpark's shares rose to $13 (+5%), BitFuFu's shares increased to $1.42 (+7%), while Canaan's shares fell to $0.20 (-1.5%).

The lessee will deploy infrastructure with a capacity of 175 MW, with the facility expected to be operational by the fourth quarter of 2027. The agreement includes two five-year extension options, potentially bringing the total deal value to $11.6 billion.

According to CleanSpark CEO Matt Schultz, this contract marks the company's transition from Bitcoin mining to a diversified digital infrastructure model and will enable the commercialization of energy assets.

Simultaneously, the parties signed an agreement for exclusive negotiations regarding CleanSpark's entire portfolio in Texas, which includes two sites totaling 718 acres with a potential capacity of up to 885 MW for data center development.

The company anticipates that the contract will generate approximately $330 million in net operating income annually, with nearly a 100% operating margin.

CleanSpark began pivoting toward AI infrastructure in the fall of 2025, announcing plans to develop its data center business and exploring the possibility of retrofitting its energy sites for AI workloads.

Additionally, mining company MARA Holdings has acquired a site in Matagorda County, Texas, with a total deal value potentially reaching $600 million.
