Woofun AI reports that CleanSpark, BitFuFu, and Canaan experienced a synchronized decrease in Bitcoin production during June, driven by distinct operational constraints rather than market-wide failures.

CleanSpark mined 614 Bitcoins in June, falling short of the 671 tokens generated in May. This output reduction coincided with a drop in average operating hashrate from 46 exahashes per second (EH/s) to approximately 43 EH/s, representing a 9% contraction attributed to scheduled preventive maintenance. Despite the slower mining pace, the firm’s treasury grew to 13,924 units, solidifying its position as the eleventh largest public holder of the asset.

BitFuFu recorded a sharper decline, producing 125 Bitcoins compared to 177 units in the prior cycle. Executive management cited a decrease in managed hashrate as the primary driver for this 29% drop.

However, Woofun AI data shows the company is aggressively expanding its self-owned fleet, deploying 1,200 model S21 XP mining rigs in June to raise its proprietary processing rate to 3.5 EH/s.

Structurally, the sector benefited from a technical tailwind when Bitcoin network difficulty fell by over 10% in mid-June. This marked the second-largest downward adjustment of the year, significantly lowering global computational power requirements and theoretically boosting hardware efficiency. Yet, local operational frictions prevented these miners from fully capitalizing on the eased network conditions.

Canaan faced a 29% production contraction, yielding only 64 Bitcoins versus 90 the previous month. Management linked this shortfall to electrical grid maintenance at one facility, though partial recovery was achieved through its Texas joint venture, which resumed operations after May wildfires caused halts. Consequently, Canaan added 49 Bitcoins to its historical treasury.

Market reactions diverged sharply following the announcements. CleanSpark shares rallied 7.7% to close at $13.30 on Tuesday, likely buoyed by the confirmation of a 20-year, $6.6 billion lease agreement for an AI data center campus in Georgia. In contrast, BitFuFu shares advanced 6% to $1.42, while Canaan stock fell 1.5% to settle at $0.30.

This volatility unfolded as Bitcoin’s spot price recovered above $64,200, rebounding from a near two-year low of $57,800 late in the month. The next critical milestone for the sector will be the activation of BitFuFu supply contracts scheduled for August.
