Bitcoin Hashrate Falls as Miners Redirect Power to AI

Bitcoin’s network hashrate has dropped roughly 20% from its early-2026 peak near 1,200 EH/s to the 903-948 EH/s range, as publicly traded miners redirect computing infrastructure toward AI workloads that generate an estimated 3-4x more revenue per megawatt than proof-of-work block rewards.

Bitcoin traded at $68,191 at press time, down 0.87% over 24 hours, with a market cap of approximately $1.36 trillion. The Fear & Greed Index sat at 8 (Extreme Fear), reflecting broad risk-off positioning across the crypto market.

Hashrate Down ~20% From Peak; Difficulty Drops 7.76%

Bitcoin’s total network hashrate peaked near 1,200 EH/s in early 2026 before declining to the 903-948 EH/s range, per U.Today reporting. The contraction represents a roughly 20% pullback from the all-time high.

Mining difficulty fell 7.76% to 133.79 trillion at block height 941,472. That marks the second-largest negative difficulty adjustment of 2026, signaling hashrate is leaving the network faster than new capacity replaces it.

Hash price, the revenue a miner earns per petahash per second per day, has compressed alongside the decline. With Bitcoin mining yielding an estimated $57-$129 per megawatt versus $200-$500 per megawatt for AI data center operations using identical power capacity, the economic case for pure-play mining has weakened sharply since the April 2024 halving cut block rewards to 3.125 BTC.

The difficulty retarget mechanism is functioning as designed: fewer miners means lower difficulty, which improves unit economics for remaining operators. But the deal flow suggests this exodus is structural, not cyclical.

AI Contracts Worth $37B+ Drive Miner Reallocation

The capital shift is formalized in multi-billion-dollar contracts with the world’s largest technology companies. Four major miners have committed to AI infrastructure deals with a combined value exceeding $37 billion.

IREN had approximately 99,900 GPU installations or orders as of December 31, 2025, and ran a daily BTC liquidation strategy, holding zero Bitcoin on its balance sheet at year-end. Hut 8’s CEO described the Google-backstopped deal as the “first domino to fall.”

Core Scientific’s Q4 2025 earnings illustrate the transition: self-mining revenue fell 47% year-over-year to $42.2 million, while colocation revenue grew 268% to $31.3 million from $8.5 million. The company sold $402.5 million in digital assets during 2025.

Wall Street has responded by revaluing pivoting miners as critical energy infrastructure assets rather than pure-play crypto operations. These companies control scarce, grid-connected power capacity that AI hyperscalers need, a dynamic that has reshaped crypto market narratives this week.

80,000 BTC Overhang: Miner Sell Pressure Compounds Near-Term Risk

Marathon Digital (MARA) sold 4,076 BTC for $413.1 million during 2025 but still holds approximately 53,822 BTC. Cipher Mining sold roughly $214.7 million in Bitcoin and classified $94.9 million in mining equipment as held for sale.

Across the sector, public Bitcoin miners collectively hold an estimated 80,000 BTC on balance sheets, a stockpile at risk of further liquidation to fund AI capital expenditure. Quinn Thompson, CIO of Lekker Capital, noted that the AI pivot, “while helpful to long-term health, presents a dilemma for prices in the near-term.”

The concern is straightforward: miners converting to AI need cash, and their largest liquid asset is Bitcoin. As some analysts argue Bitcoin’s four-year cycle remains in play, miner-driven sell pressure adds a variable that previous cycles did not face at this scale.

Network Security and Difficulty Outlook

A sustained hashrate decline lowers the cost of a theoretical 51% attack in direct proportion. At 1,200 EH/s, such an attack was economically impractical; at 900 EH/s, the barrier is lower in absolute terms, though still prohibitively expensive given the specialized ASIC hardware required.

Bitcoin’s difficulty retargeting mechanism adjusts every 2,016 blocks (approximately two weeks), acting as the network’s self-healing system. The 7.76% downward adjustment at block 941,472 normalizes block times toward the 10-minute target and improves remaining miners’ unit economics.

The post-halving period in 2024 saw a similar pattern: inefficient miners exited, difficulty adjusted downward, and the network found equilibrium within two to three months. The difference now is that miners are not shutting down unprofitable rigs; they are converting infrastructure to a competing use case with multi-year revenue commitments.

One angle absent from most coverage is the role of private and overseas miners. Operations in Kazakhstan, Russia, and other jurisdictions may absorb some of the hashrate void left by U.S. public miners pivoting to AI, potentially limiting how far the global decline extends alongside Bitcoin’s recent price slide.

The next difficulty adjustment, expected in approximately two weeks, will indicate whether hashrate has found a floor. If more miners finalize AI infrastructure conversions during this period, another negative adjustment is probable, further compressing hash price for remaining operators.

The current confluence of extreme fear sentiment (index at 8), a 20% hashrate contraction, and potential sell pressure from 80,000 BTC in public miner treasuries creates a near-term risk profile distinct from previous post-halving cycles. The difficulty mechanism protects network functionality, but it cannot offset the macroeconomic pressure of an industry subsector repricing its core business away from Bitcoin mining.
