"Listed miners could derive as much as 70% of their revenue from AI by end of 2026, up from roughly 30% today." — CoinShares, Q1 2026 Bitcoin Mining Report
Bitcoin mining economics have deteriorated to their worst levels since the network's inception. The weighted average cash cost to produce one bitcoin among publicly listed miners reached $79,995 in Q4 2025, according to CoinShares, while bitcoin traded between $68,000 and $76,000 through Q1 2026 — a sustained period of negative unit economics. Hashprice, the standard measure of mining revenue per unit of computational power, stood at $33.25/PH/s/day as of April 13, 2026, near breakeven for most operators. Transaction fees contributed just 0.58% of block rewards, totaling 16 BTC (~$1.2 million) daily — effectively zero as a revenue supplement.
The response has been a structural transformation of the industry. In aggregate, publicly listed bitcoin miners have signed over $70 billion in AI and high-performance computing (HPC) contracts since mid-2025. Core Scientific, Hut 8, MARA Holdings, and Riot Platforms are converting mining facilities into data centers for hyperscalers including Google, AMD, and CoreWeave. CoinShares projects that listed miners could derive 70% of total revenue from AI by year-end 2026, inverting the ratio from 85% mining / 15% AI in early 2025. The question is no longer whether bitcoin miners survive the post-halving squeeze — it is whether what survives can still be called a mining industry.
The April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC. The effect on miner revenue was immediate and has compounded over the following 12 months.
According to the CoinShares Q1 2026 Mining Report, the weighted average cash cost per bitcoin among listed miners reached approximately $79,995 by Q4 2025. With bitcoin trading at $74,247 as of April 13, 2026, the average listed miner loses roughly $5,700 per bitcoin produced before accounting for depreciation, interest, and stock-based compensation.
Hashprice — the USD revenue a miner earns per petahash per second per day — tells the same story. It collapsed from ~$55/PH/s/day in Q3 2025 to $28-30/PH/s/day by early March 2026, a post-halving all-time low. A partial recovery to $33.25/PH/s/day followed bitcoin's rebound from $60,000 to $74,000 in April. At that level, any operator running hardware older than the Antminer S19 XP with electricity costs above $0.06/kWh is underwater. CoinShares estimates this describes 15-20% of the global mining fleet.
The breakeven electricity rate for a latest-generation Antminer S21 Pro (15 J/TH) at current difficulty is approximately $0.045/kWh. For the previous-generation S19 XP (21.5 J/TH), it is $0.031/kWh. Miners paying the U.S. commercial average of $0.1363/kWh face a cost to mine one bitcoin exceeding $106,000, per BestBrokers estimates — a 43% premium over the spot price.
Network hashrate peaked above 1 ZH/s (zettahash per second) in early 2026 but has since exhibited significant volatility. CoinWarz data shows the 7-day average hashrate at approximately 1.033 ZH/s as of April 14, with block times averaging 10 minutes 22 seconds — slightly above the 10-minute target, indicating marginal overcapacity has been wrung out.
The difficulty adjustment mechanism has registered the stress:
Three consecutive negative difficulty adjustments occurred in Q1 2026, the first such streak since July 2022. This pattern historically signals miner capitulation — operators shutting machines and selling bitcoin reserves to cover obligations.
The post-halving thesis held that transaction fees would gradually replace declining block subsidies. The data does not support this.
As of April 12, 2026, the average bitcoin transaction fee was $0.18 per transaction, per YCharts. Daily fee revenue totaled approximately $300,000 — a 12-month low — representing less than 1% of total miner income. On a per-block basis, miners collected an average of 0.0163 BTC in fees per block, down 1% week-over-week per HashrateIndex data.
For context, the block subsidy generates 3.125 BTC per block (~$232,000 at current prices). Fees add $0.18 per transaction across roughly 300,000-400,000 daily transactions. The fee-to-reward ratio has stabilized near 0.58%, compared to brief spikes above 15% during Ordinals and BRC-20 activity in late 2023 and early 2024.
Bitdeer's 2026 research report notes that while the fee-to-revenue ratio averaged roughly 15% through 2026, the figure is skewed by isolated spikes. The median contribution is far lower. The Bitcoin network has not yet developed a sustainable fee market capable of compensating for declining subsidies.
The economic response has been decisive. According to CoinShares, listed bitcoin miners have collectively signed over $70 billion in GPU co-location and cloud service agreements with hyperscalers and AI infrastructure firms. The contracts leverage miners' core competitive advantage: access to large-scale, permitted power capacity at sites already equipped with cooling, backup generation, and high-voltage grid connections.
The major deals signed through Q1 2026:
| Company | Counterparty | Capacity | Contract Value | Duration | |---------|-------------|----------|---------------|----------| | Core Scientific | CoreWeave | 590 MW | $10.2B | 12 years | | Hut 8 | Fluidstack (Google-backed) | 245 MW | $7.0B ($17.7B w/ renewals) | 15 years | | MARA Holdings | Starwood Capital | 1+ GW (2.5 GW pathway) | Undisclosed | Multi-year | | Riot Platforms | AMD | 200 MW | $311M ($1B w/ extensions) | 10 years | | TeraWulf | Undisclosed | Multiple sites | $12.8B contracted | Multi-year | | IREN | Multiple hyperscalers | GW-scale | $2.3B contracted ARR | Multi-year |
Core Scientific is more than halfway toward delivering its 590 MW commitment to CoreWeave and expects to complete the full buildout by early 2027, per the company's Q4 2025 earnings disclosure. Core Scientific sold approximately 1,900 BTC ($175 million) in January 2026 alone to fund AI capital expenditure, and has stated it plans to monetize "substantially all" remaining bitcoin holdings through 2026.
Hut 8's River Bend campus in Louisiana represents a different model: a $7 billion, 15-year lease backed by Google's financial guarantee, which enabled project financing from JPMorgan and Goldman Sachs. The first data hall is scheduled for Q2 2027 commissioning.
MARA's February 2026 partnership with Starwood Capital covers the conversion of its U.S. mining sites into hybrid facilities capable of dynamically switching between bitcoin mining and AI/HPC workloads based on market conditions. MARA retains up to 50% ownership.
Bitfarms has announced a full exit from mining at its Washington state facility, converting entirely to HPC/AI hosting by 2027, per DataCenterDynamics.
The financial divergence among listed miners reflects their positioning on the mining-to-AI spectrum.
Marathon Digital (MARA): Reported $238 million in revenue for its most recent quarter, up 64% year-over-year. Holds 52,850 BTC (~$3.4 billion) in treasury. Operational hashrate grew 82% year-over-year. The Starwood JV targets 1+ GW of AI-ready capacity.
Riot Platforms (RIOT): Recorded $647 million in annual revenue for 2025, a record. Sold 3,778 BTC ($289.5 million) in Q1 2026 to fund data center expansion. Maintains $1.3 billion in liquidity including 18,000+ BTC. The AMD lease alone could generate $1 billion over its full term. Activist investor Starboard Value estimated Riot's 1.7 GW power pipeline could yield $1.6 billion in annual EBITDA if fully monetized for AI.
CleanSpark (CLSK): Achieved $766 million in FY 2025 revenue with operational hashrate exceeding 50 EH/s. Maintains among the lowest SG&A costs in the industry at $17,848/BTC.
Core Scientific (CORZ): AI colocation revenue surged 268% year-over-year. Mining revenue declined as the company liquidated bitcoin holdings to fund infrastructure conversion. Management expects bitcoin mining to fall below 20% of total revenue by end of 2026.
IREN: AI services revenue jumped 137% quarter-over-quarter to $17.3 million with 86% gross margins. Projects $3.4 billion in annualized recurring revenue for 2026, with $2.3 billion already under contract.
The market has split bitcoin mining equities into two tiers. According to CoinShares data, miners with secured HPC/AI contracts trade at approximately 12.3x next-twelve-month (NTM) sales. Pure-play miners without AI exposure trade at 5.9x NTM sales — a 108% valuation premium for AI exposure.
This bifurcation creates a self-reinforcing dynamic. Higher-valued companies access cheaper capital, enabling faster infrastructure conversion, which further widens the gap. Smaller miners without the balance sheet to fund an AI pivot face three options: sell to a larger operator, secure a hosting contract, or shut down.
CoinTelegraph's 2026 mining outlook report noted that industry consolidation has accelerated, with Canaan Inc. acquiring a 49% stake in a West Texas mining joint venture from Cipher Mining for $39.75 million in February 2026.
The economic pressure on miners raises a question about Bitcoin network security that the data can partially address.
Despite Q1 capitulation, the 7-day average hashrate remains above 1 ZH/s — orders of magnitude above what would be needed to 51%-attack the network. The difficulty adjustment mechanism is functioning as designed: when unprofitable miners exit, difficulty drops, margins improve for remaining operators, and an equilibrium re-establishes.
However, the concentration of hashrate among fewer, larger operators is increasing. The top five publicly listed miners — MARA, Riot, CleanSpark, Core Scientific, and IREN — collectively control an estimated 25-30% of total network hashrate, up from approximately 15-20% two years ago. If these operators continue shifting capacity toward AI workloads, the effective hashrate devoted to bitcoin may decline even as total installed capacity grows.
The hybrid model — exemplified by MARA's Starwood partnership — where facilities dynamically switch between mining and AI based on real-time profitability, introduces a new variable. Bitcoin network security becomes partially contingent on the relative profitability of AI compute versus bitcoin mining at any given moment.
The bitcoin mining industry is undergoing a structural transformation driven by arithmetic, not strategy. The halving cut revenue by 50%. Transaction fees have not compensated. Electricity and hardware costs have not declined proportionally. The result is an industry where the core product — mining bitcoin — generates negative margins for the average operator.
The AI pivot is not a diversification play; it is a survival mechanism. Miners possess permitted power capacity, grid interconnections, cooling infrastructure, and physical security — assets that AI hyperscalers need and cannot build fast enough on their own. The $70 billion in signed contracts reflects the market's pricing of these assets independent of bitcoin mining.
What emerges is an industry that still mines bitcoin but increasingly treats it as a byproduct of operating power infrastructure. The economic center of gravity has shifted. Whether this constitutes a healthier, more sustainable mining ecosystem or an existential redefinition of what "bitcoin mining" means is a question the next halving cycle — and the fee market — will answer.
