Bitcoin’s mining difficulty saw one of its steepest drops ever at block 953,568, falling from 138.96 trillion to 124.93 trillion, a 10.09% decline. This ranks as the 11th-largest downward adjustment in the network’s history and the second largest this year. The adjustment mechanism, which recalibrates every 2,016 blocks to maintain an average block time of 10 minutes, responded to a slowdown in block production caused by lower prices.
Galaxy Research attributed the drop to Bitcoin’s price slide of roughly 15% in June 2026, which squeezed miner margins and forced many operators to shut down less efficient rigs. The previous mining epoch lasted 15.6 days instead of the usual 14 days, indicating reduced hashrate competition before the difficulty correction took effect. This slower block production is exactly the condition that triggers a downward retarget under Bitcoin’s protocol.
For miners that remain active, the lower difficulty means they can produce more Bitcoin with the same computational power. It may also help lift the hashprice—the revenue per unit of hashing power—back above $30 per PH/s. However, not all miners benefit equally; those with newer gear and cheaper energy are better positioned to capitalize on the adjustment, while older machines remain vulnerable if prices fall further or electricity costs stay high.
Beyond the immediate mining landscape, the hashrate decline is partly driven by a broader industry trend: mining firms are reallocating power capacity toward high-performance computing and AI data centers. Core Scientific, for instance, is converting its Pecos, Texas mining site into a massive AI data center campus, repurposing 300 megawatts of mining power. TeraWulf reported that its HPC hosting revenue surpassed Bitcoin mining revenue in Q1 2026, totaling $21 million. HIVE Digital has also announced a 320 MW AI project near Toronto designed to host over 100,000 GPUs.
The shift toward AI computing reflects a strategic pivot as miners seek more stable revenue streams amid Bitcoin price volatility. While the difficulty adjustment provides temporary relief for active miners, the long-term pressure on margins remains, and the industry is adapting by diversifying into adjacent technologies.
