"It is grim for miners right now." — Nick Hansen, CEO, Luxor Mining
Bitcoin mining difficulty is projected to drop approximately 9% on June 13, 2026, from 138.96T to an estimated 126.51T, marking the continuation of a capitulation cycle that has seen three consecutive negative difficulty adjustments — the first such streak since July 2022. The network hashrate, which peaked at 1,160 EH/s in early October 2025, has declined to approximately 1,020 EH/s, with sustained stretches below 900 EH/s earlier in the year.
The weighted average cash cost to produce one bitcoin among publicly listed miners stood at $79,995 as of Q4 2025, according to CoinShares. With BTC trading near $62,000 as of June 5, 2026, the median publicly listed miner operates at a loss on every coin produced. Hash price — the standard measure of miner revenue per unit of computational power — fell to $28-30/PH/s/day in early 2026, a post-halving low, before recovering modestly to $30-35/PH/s/day. An estimated 15-20% of the global mining fleet is now unprofitable.
The response has been structural, not cyclical. Publicly listed miners have collectively reduced BTC treasuries by over 15,000 BTC from peak levels. Core Scientific liquidated approximately 1,900 BTC ($175 million) in January 2026 alone. Bitdeer emptied its entire bitcoin treasury in February. MARA Holdings, the largest public miner by production, formally expanded its corporate policy in 2026 to permit balance sheet bitcoin sales. The sector is bifurcating into two distinct categories: pure-play miners fighting margin compression, and infrastructure operators pivoting aggressively into AI and high-performance computing.
The April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC. Combined with a 31% BTC price drawdown from the October 2025 all-time high of approximately $124,500 to $86,000 by late December, and a further decline to the $62,000 range by early June 2026, the economics of bitcoin mining have deteriorated to levels not seen in over five years.
Hash price — the revenue a miner earns per petahash per second per day — peaked at approximately $63/PH/s/day in July 2025. By November, it had fallen to $35-38/PH/s/day. By late February 2026, it collapsed to $28-30/PH/s/day, setting a new five-year low. The modest recovery to $30-35/PH/s/day at present does not materially change the picture for operators running anything older than latest-generation ASICs.
At current hash prices, miners running mid-generation hardware require access to sub-$0.05/kWh electricity to remain cash-profitable. Machines consuming more than 25 J/TH — which includes much of the installed base — are losing money at typical industrial electricity rates. The S19 XP breakeven electricity cost rose to $0.077/kWh by December 2025, up from $0.12/kWh a year earlier, reflecting compressed margins even for relatively efficient hardware.
CoinShares' Q1 2026 Bitcoin Mining Report provides granular cost data for publicly listed miners during Q4 2025, the most challenging quarter since the halving:
| Company | BTC Mined (Q4) | Cash Cost/BTC | All-In Cost/BTC | |---------|----------------|---------------|-----------------| | HUT 8 | 719 | $50,332 | $160,402 | | IREN | 1,664 | $58,462 | $140,441 | | CleanSpark | 1,821 | $71,188 | $118,932 | | HIVE | 884 | $75,274 | $144,321 | | Bitdeer | 1,673 | $87,144 | $118,188 | | MARA | 2,011 | $103,605 | $153,040 | | Riot Platforms | 1,324 | $102,538 | $170,366 | | Cipher Mining | 591 | $103,516 | $231,980 | | Core Scientific | 421 | $110,282 | $168,693 | | TeraWulf | 262 | $384,517 | $471,841 |
The data reveals a wide dispersion in cost structures. Hut 8 and IREN operated at cash costs below the then-prevailing BTC price. MARA, Riot, Cipher, and Core Scientific were already cash-negative in Q4 2025, when BTC averaged approximately $95,000. At current prices near $62,000, every listed miner in this sample — including the most efficient operators — faces margin pressure on a cash-cost basis.
TeraWulf's all-in cost of $471,841 per BTC reflects its strategic reallocation: the company now derives the majority of its revenue from AI/HPC hosting rather than bitcoin mining, making its per-BTC cost metrics misleading in isolation.
The HODLing strategy that defined public miners during the 2020-2025 bull cycle has reversed. Publicly listed miners collectively reduced BTC treasuries by more than 15,000 BTC from peak levels during the period examined:
The shift from accumulation to liquidation reflects operational necessity. Miners are selling BTC to fund electricity costs, service debt, and finance the capital-intensive pivot to AI infrastructure.
Bitcoin's network hashrate peaked at 1,160 EH/s in early October 2025, coinciding with the BTC all-time high. It declined to approximately 1,045 EH/s by late December, then dropped sharply to 850 EH/s by early February 2026 before recovering to approximately 1,020 EH/s.
Mining difficulty, which peaked at 155.97T on October 29, 2025, has recorded three consecutive negative adjustments — the first such streak since July 2022 — a standard technical marker of miner capitulation. The difficulty dropped 7.76% in the most recent adjustment, the second-largest decline of 2026. The next adjustment, estimated for June 13, is projected to decrease difficulty from 138.96T to approximately 126.51T, a further 9% decline.
When hashrate leaves the network, blocks are produced more slowly. Difficulty adjusts downward to compensate, effectively making mining easier for the operators that remain online. The projected June 13 adjustment, if realized, would confirm that significant hashrate has exited the network during the current price drawdown.
The sector has structurally bifurcated. CoinShares categorizes public miners into two groups: "infrastructure companies" (TeraWulf, Core Scientific, Cipher Mining, Hut 8) and "mining companies" (MARA, CleanSpark, Riot, HIVE). The distinction is revenue composition.
Cumulative AI/HPC contracts announced by listed miners now exceed $70 billion in total committed value. According to CoinShares, publicly listed Bitcoin miners could derive up to 70% of their revenues from AI by December 2026, up from approximately 30% at the start of the year.
Select contract values and capacity commitments:
Riot Platforms reported $167.2 million in total revenue for Q1 2026, with its data center business contributing $33.2 million. Core Scientific stock rose approximately 40% year-to-date, outperforming BTC, as investors repriced it as an AI infrastructure play.
The economic logic is straightforward: AI deals offer 80-90% margins and long-term contractual stability, compared to bitcoin mining's volatile, margin-compressed revenue profile.
The AI pivot carries significant financial risk. Several miners have taken on substantial debt to fund the transition:
These debt loads are predicated on AI/HPC contracts materializing as projected and on the broader AI infrastructure spending cycle continuing. If AI capital expenditure decelerates — or if hyperscaler clients renegotiate or cancel contracts — miners-turned-data-center-operators face debt service obligations against potentially reduced revenue.
The Hash Ribbon indicator, which tracks the relationship between short-term and long-term hashrate moving averages, has been in capitulation mode for three months — described by Glassnode as one of the longest capitulations on record. According to CoinDesk, the indicator is approaching a recovery signal, a pattern that has historically aligned with local or major bitcoin price bottoms.
The capitulation cycle appears to be in Phase 4, the "survivors stabilizing" phase. If historical patterns hold, the hash ribbon signal suggests a price bottom may form within 2-4 months. However, past performance provides no guarantee of future outcomes, and the current macro environment — with the Fed's June statement removing language about progress toward the 2% inflation target and rate cuts potentially pushed into 2027 — introduces variables not present in prior capitulation cycles.
The bitcoin mining industry is undergoing a structural transformation that extends beyond typical cyclical stress. The combination of halved block rewards, a 50% BTC price decline from all-time highs, and near-record hashrate created a margin environment in which the median listed miner cannot profitably produce bitcoin.
The response — mass treasury liquidation, aggressive AI infrastructure pivots, and multi-billion-dollar debt issuance — is reshaping what "bitcoin mining companies" actually are. By year-end 2026, the majority of revenue for many listed miners will come from AI hosting, not BTC production.
The projected 9% difficulty drop on June 13 will provide temporary relief to remaining operators. The hash ribbon signal suggests a potential cyclical bottom within months. But the industry that emerges from this capitulation will look fundamentally different from the one that entered it. The energy and compute assets remain; the business model has changed.
