Bitcoin's mining difficulty just recorded its 11th-largest downward adjustment as miners redirect computing power toward AI infrastructure.

Bitcoin's network hashrate fell 23% from its October peak to 886 EH/s, triggering a 10.09% difficulty cut on June 15 — the 11th-largest downward adjustment in the network's history.
"The migration of Bitcoin miners toward AI and high-performance computing is accelerating rapidly," the CoinShares Bitcoin Mining Report for Q1 2026 said. "Listed miners could derive as much as 70% of their revenues from AI by the end of this year, up from roughly 30% today."
The difficulty adjustment, which took effect at block 953,568, lowered the mining target from 138.96 trillion to 124.93 trillion after the current epoch ran 15.6 days instead of the typical 14, according to Galaxy Research. Hashprice — the estimated daily revenue per petahash per second — has recovered from below $28 to approximately $33, crossing the $30 threshold widely considered the gross breakeven point for higher-cost operators, per Hashrate Index.
The structural shift raises a longer-term question for Bitcoin's security budget: if large miners continue redirecting infrastructure toward AI workloads, the hashrate may struggle to recover even if BTC prices rise. Nakamoto Director of Corporate Development Brandon Bailey said in a recent Blockspace interview that "in the medium term, we could see a situation in which mining economics actually do appreciate materially just because you have so much power capacity that is tied to a different use."
$70 Billion in AI Contracts Reshape Mining Economics
Publicly listed miners have announced over $70 billion in cumulative AI and high-performance computing contracts, according to industry data. Cango sold $305 million worth of its bitcoin holdings to fund its AI pivot, while Bitdeer disclosed Friday that it still holds zero bitcoin on its books. CoinShares warned that while most of these deals involve new data centers, "some cannibalisation and shutting down of existing mining facilities will occur."
The hashrate decline accelerated in Q2 2026, falling 5.8% to 1,004 EH/s as rising power prices pushed marginal operators offline. Electricity now represents 70% to 90% of mining operating costs, and competition from AI data centers has made cheap power harder to secure.
What Comes Next for Bitcoin Mining
The next difficulty adjustment is estimated for June 27, with CoinWarz projecting a slight increase of about 1.69% to approximately 128.58 trillion, reflecting a modest hashrate recovery as improved economics pull some machines back online. But CoinShares projects the hashrate could reach 1.8 zettahash by end-2026 only if Bitcoin returns above $100,000 to make mining economically viable for remaining operators.
Bitcoin traded near $64,000 on Monday, roughly half its October all-time high of $125,000. The price rose above $67,000 after news of a preliminary U.S.-Iran peace agreement, though billionaire investor Mark Cuban recently cited Bitcoin's continued correlation with risk assets as his reason for selling nearly all of his holdings, saying the asset has failed to live up to its "digital gold" use case.
