Bitcoin Mining in Crisis: The Great Hashrate Exodus of 2026

Hashrate: Volatile but Recovering from Lows

The 7-day average hashrate dipped to around 880–894 EH/s in mid-July, but rebounded quickly to ~937–938 EH/s by late July, according to the Hashrate Index . The “~868 EH/s” figure reported by some outlets appears to represent a transient intra-month low rather than the prevailing end-of-month level . The hashrate decline from the all-time high has been persistent — over 287 consecutive days of contraction at one point — but the July rebound suggests some marginal capacity came back online after the 5% difficulty cut improved miner economics .

Miner Economics: Squeezed but Not Broken

The financial picture for miners remains challenging.

• BTC price: ~$63,040–$63,100 as of late July 2026 .
• Hashprice: ~$32.34 per PH/s/day, up from $30.88 in the prior week . However, VanEck reported hashprice at ~$30.6/PH/s/day with daily miner revenue averaging just $28.5 million — down 39.5% year-over-year . At $32/PH/s/day, hashprice sits near breakeven for many operators, depending on electricity costs and machine efficiency .
• BTC-denominated hashprice is essentially flat at 0.00049705 BTC/PH/s/day , meaning the revenue improvement came entirely from the USD price of bitcoin, not from any mining-specific tailwind.
• The block reward has been 3.125 BTC since the April 2024 halving, compounding the revenue pressure .

Operations running older-generation hardware above 25 J/TH in regions with power costs exceeding $0.06/kWh are likely operating at a loss or on razor-thin margins. Conversely, operators with access to sub-$0.04/kWh power and next-generation ASICs remain solidly profitable .

Record Miner BTC Sales in Q1 2026

Public miners sold bitcoin at a record pace in Q1 2026, offloading more than 32,000 BTC — exceeding total net sales across every quarter of 2025 and surpassing the roughly 20,000 BTC sold during the Terra-Luna collapse in Q2 2022 . The selling was driven by the need to fund operations, repay debt, and finance the pivot to AI infrastructure. Major sellers included MARA, CleanSpark, Riot Platforms, Cango, Core Scientific, and Bitdeer . This record selling pressure was a major factor behind the prolonged difficulty contraction .

The AI/HPC Pivot: $70 Billion and Structurally Permanent

This is not a cyclical downturn. It is a structural reallocation of capital. Publicly listed miners have now announced over $70 billion in cumulative AI and high-performance computing (HPC) contracts . These are not tentative agreements. Key deals include:

• Hut 8 — $16.8 billion in triple-net, take-or-pay contracted lease revenue across two hyperscale AI campuses, including a 15-year, 352 MW IT load lease with an investment-grade counterparty .
• Core Scientific — $10.2 billion, 12-year contract with CoreWeave, plus additional capacity under development .
• TeraWulf — $12.8 billion in projected revenue from contracted HPC/AI capacity .

These contracts are long-duration (12–20 years), triple-net, take-or-pay agreements, meaning the counterparty must pay regardless of usage . This makes the shift structural, not cyclical — power capacity and capital once allocated to ASIC mining racks are being permanently converted to GPU clusters. AI-related services are projected to constitute up to 70% of these companies' revenue by end of 2026, up from ~30% in early 2026 . Many of these operators are unlikely to ever return meaningful hashrate to the Bitcoin network.

Outlook Ahead of the Next Adjustment (~August 9–11)

With the 30-day SMA hashrate at ~938 EH/s and difficulty at 126.23 trillion, the next difficulty adjustment around August 9–11 could see a modest increase if hashrate continues its recovery — but the direction is uncertain . The 5% July 11 cut and 0.74% July 25 cut reflected staggered miner exits; if those exiting miners have now fully disconnected, difficulty may stabilize or even inch up . However, the structural diversion of power to AI/HPC means the network may face a permanently lower difficulty equilibrium than historical trendlines would suggest, and another downward adjustment remains possible if BTC price and hashprice fail to sustain current levels .
