"AI companies pay much more per electron compared to mining." — Fred Thiel, CEO, MARA Holdings
Public Bitcoin miners sold a record 32,000 BTC in Q1 2026, exceeding total net sales for all of 2025, as the industry undergoes a structural reallocation of power infrastructure from proof-of-work hashing to artificial intelligence compute. Combined listed-miner Bitcoin treasuries fell from approximately 127,000 BTC to 99,000 BTC by mid-2026, a 22% drawdown. Compressed mining margins — with production costs near $80,000 per BTC for mid-tier operators — and a 20x revenue-per-megawatt premium for AI workloads are driving the shift.
The pivot accelerated through September 2026. MARA Holdings, the largest publicly traded miner by market capitalization, sold 20,880 BTC ($1.5 billion) in Q1 to retire convertible debt and fund AI infrastructure, then reversed course on September 16, purchasing 1,292 BTC ($98.6 million) through institutional broker FalconX. Riot Platforms offloaded 9,665 BTC in H1 2026. Bitdeer reduced its treasury to zero. Core Scientific exited self-mining to focus on a $24 billion AI colocation pipeline. The sector is splitting into two camps: operators converting megawatts to AI revenue, and a shrinking cohort still accumulating BTC as a treasury asset.
Publicly listed Bitcoin miners collectively sold over 32,000 BTC in the first quarter of 2026, according to on-chain analytics and company filings. This figure surpassed their combined net sales for the entirety of 2025. The aggregate dollar value exceeded $2.5 billion at prevailing prices.
The selling was broad-based. Major participants included MARA Holdings, Riot Platforms, Core Scientific, CleanSpark, Cango, and Bitdeer. Combined listed-miner treasuries, which topped 100,000 BTC as recently as 2024 and reached approximately 127,000 BTC at peak, fell to roughly 99,000 BTC by mid-2026 — a net reduction of 28,000 BTC.
This was not panic selling. Proceeds were directed toward three primary uses: debt retirement, operational expenditure coverage in a compressed-margin environment, and capital investment in AI and high-performance computing (HPC) infrastructure. The pattern represents a deliberate capital reallocation, not a capitulation event, though the volume of BTC hitting exchanges contributed to downward price pressure.
The revenue gap between Bitcoin mining and AI compute has become the central fact of the sector. According to industry data compiled by CoinShares and multiple mining analysts:
| Metric | Bitcoin Mining | AI/HPC Compute | |--------|---------------|----------------| | Revenue per MWh | $80–$151 | $1,500–$4,000 | | Infrastructure cost per MW | $700K–$1M | $8M–$15M | | Profit margins | 10–30% (at current BTC price) | 80–90% (contracted) | | Revenue multiple vs. mining | 1x | 3–25x |
The April 2024 halving cut block rewards from 6.25 to 3.125 BTC. Subsequent difficulty increases through 2025 and into 2026 pushed the average production cost for mid-tier miners to approximately $80,000 per BTC. Only operators with electricity rates below $0.03/kWh or access to stranded energy remain consistently profitable on mining alone.
AI infrastructure requires 10–15x the capital expenditure per megawatt, but contracted revenue streams — often structured as 15-year leases — provide predictability that spot mining cannot match. The result: projections suggest listed miners could derive up to 70% of their revenue from AI by end-2026, up from roughly 30% at the start of the year.
Sold 9,665 BTC in H1 2026. Q1 sales alone totaled 3,778 BTC for $289.5 million. Riot holds a 191 MW lease with Anthropic at its facility, projected to generate $9.1 billion in revenue through 2048. The Anthropic contract alone represents a fundamental shift in the company's revenue base away from block rewards.
Liquidated approximately 1,900 BTC ($175 million) in January 2026 and signaled intent to sell "substantially all" remaining holdings during the year. The company signed a 15-year, 529 MW deal with AMD for AI infrastructure, with potential contracted revenue of $14 billion. In Q2 2026, colocation revenue hit $136.7 million (83% of total quarterly revenue of $164.2 million), while self-mining revenue collapsed 66% to $21.5 million. Core Scientific's total leased customer capacity now exceeds 1.1 GW, representing over $24 billion in potential contracted revenue.
Reduced its Bitcoin treasury to zero by February 22, 2026. The Singapore-based miner, led by Jihan Wu, began the year with approximately 2,000 BTC, dropped to 1,530 BTC by end of January, fell to 943.1 BTC by February 13, and liquidated the remainder days later. Proceeds were allocated to "powered land acquisition opportunities" for AI data center expansion. The total liquidation marked a departure from the HODL strategy that previously defined the company's treasury management.
Sold 2,000 BTC in March for approximately $143 million.
Participated in the Q1 selling wave, though the company has maintained a relatively larger BTC treasury position compared to peers pursuing full AI pivots.
MARA Holdings presents the most complex case study in the sector. The company executed three distinct phases in 2026:
Phase 1 — Liquidation (Q1 2026): MARA sold 20,880 BTC for approximately $1.5 billion. Of this, 15,133 BTC ($1.1 billion) was sold in March alone. A $1.0 billion tranche of proceeds went to repurchase convertible senior notes due 2030 and 2031 at a discount, reducing outstanding debt by approximately 30%.
Phase 2 — Infrastructure Acquisition (Q1–Q2 2026): In February, MARA announced a partnership with Starwood Capital Group targeting roughly 1 GW of near-term IT capacity, with a pathway to 2.5 GW. Select MARA mining locations would be converted into facilities serving enterprise cloud and AI customers. On April 30, MARA agreed to acquire Long Ridge Energy & Power for $1.5 billion from FTAI Infrastructure, gaining a 505 MW gas plant and 1,600 acres in Ohio, with over 1 GW of power capacity for AI buildout. The deal included assumption of $785 million in debt, backstopped by a bridge loan from Barclays. The acquisition increased MARA's total power capacity by 65% and added $144 million in annualized adjusted EBITDA. MARA now controls over 4 GW of power capacity.
Phase 3 — Re-Accumulation (June–September 2026): Having completed the debt restructuring and secured its infrastructure pipeline, MARA quietly returned to BTC accumulation. In June, the company purchased 1,000 BTC through FalconX. On September 16, it added another 1,292 BTC for $98.6 million at an average price of approximately $76,347 per coin, as detected by Lookonchain before any formal company announcement. MARA now holds 35,577 BTC (including 9,270 BTC under its separate digital asset strategy), worth approximately $2.7 billion at current prices.
Despite the strategic pivot, MARA reported a Q1 2026 net loss of $1.26 billion, driven primarily by a $1.0 billion negative fair-value adjustment on its Bitcoin holdings. MARA's first AI infrastructure construction is targeted to begin in H1 2027, with initial capacity delivery expected mid-2028.
The scale of AI infrastructure contracts signed by former mining companies in 2026 exceeds the combined market capitalization of most listed miners at 2025 year-end:
| Company | Deal | Value | Partner | Term | |---------|------|-------|---------|------| | Hut 8 | Beacon Point Campus (Phase 1) | $9.8B | Undisclosed | 15 years | | Hut 8 | Beacon Point Campus (Phase 2) | $9.8B | Undisclosed | 15 years | | Core Scientific | AI Colocation | $14B | AMD | 15 years | | Riot Platforms | AI Compute Lease | $9.1B | Anthropic | Through 2048 | | MARA | Long Ridge Acquisition | $1.5B | — | — | | MARA | Infrastructure Partnership | — | Starwood Capital | — |
Hut 8's Beacon Point AI data center campus in Nueces County, Texas, has been fully commercialized across two leases totaling $19.6 billion in base-term contract value, with renewal options that could lift the total to approximately $25 billion. Hut 8 shares surged over 30% on the initial announcement.
These deals are structured around NVIDIA compute architecture, designed for AI training and inference workloads at hyperscale. Several facilities feature "flex design" — the ability to dynamically switch workloads between Bitcoin mining and AI/HPC based on electricity prices and customer demand.
Bitcoin mining difficulty stood at 127.45T as of September 7, 2026 (block 965,664). The network hashrate fluctuated between 914–1,001 EH/s in early September, remaining below the symbolic 1 ZH/s threshold on a sustained basis.
Hashprice — the revenue per petahash per day — climbed from $32.42 to $39.63 over the month leading into early September, providing modest margin relief. However, at a BTC price of approximately $76,000–$79,000, operators with all-in production costs above $70,000 per BTC face thin or negative margins on mining operations alone.
The June 2026 difficulty adjustment saw a 10.09% decline at block 953,568, the second-largest drop of the year, reflecting miner capitulation and hardware decommissioning as unprofitable units were taken offline.
The Bitcoin mining industry is undergoing a structural transformation driven by simple economics: AI workloads pay 3–25x more per megawatt than proof-of-work hashing. The 32,000 BTC sold by public miners in Q1 2026 was not a distress sale — it was a capital rotation. Miners are converting the one asset class they understand (energy infrastructure) into a higher-yielding use case (AI compute), while selectively maintaining BTC exposure where balance sheets allow.
MARA's trajectory — sell BTC, retire debt, acquire power assets, then resume buying — may represent the template for surviving the post-halving margin compression. The company's 35,577 BTC treasury and 4+ GW power portfolio position it across both revenue streams. Whether this dual strategy is sustainable depends on execution of AI infrastructure buildouts through 2027–2028 and the trajectory of Bitcoin's price relative to production costs.
The sector is bifurcating. Companies with executed AI contracts (Core Scientific, Hut 8, Riot) are being re-rated as infrastructure plays. Companies still dependent on mining revenue face margin pressure at current difficulty and price levels. The BTC treasury question — hold, sell, or cycle — is now secondary to the megawatt question: how much power can you convert, and at what price.
