"We are no longer a Bitcoin company. We are an infrastructure-first owner and developer for HPC/AI data centers across North America." — Ben Gagnon, CEO, Bitfarms (rebranding as Keel Infrastructure)
Public Bitcoin miners liquidated more than $2.5 billion in BTC treasury holdings during Q1 2026, the largest quarterly sell-off by the sector on record. MARA Holdings sold 15,133 BTC for $1.1 billion in a single three-week span ending March 25. Bitdeer reduced its treasury to zero. Core Scientific expects to monetize "substantially all" of its remaining bitcoin this year. The catalyst is straightforward: AI compute infrastructure generates 3x to 25x more revenue per kilowatt-hour than Bitcoin mining, and hash price collapsed to $28-30/PH/s/day — a post-halving low.
The industry-wide pivot coincides with a broader corporate bitcoin reckoning. According to data aggregated by BitcoinTreasuries.net, 77.4% of public companies holding BTC on their balance sheets are now underwater, with 65.6% sitting more than 20% below cost basis. Bitcoin's mining difficulty dropped 7.76% at block height 941,472, the second-largest negative adjustment of 2026, as hashrate retreated from the 1 zetahash record set in 2025 to roughly 903-948 EH/s.
The scale of miner BTC liquidation in Q1 2026 is without precedent in the post-halving era:
MARA Holdings — Sold 15,133 BTC between March 4-25 at an average price of approximately $65,300 per coin, generating $1.1 billion in proceeds. The company used the capital to repurchase $1.0 billion in zero-coupon convertible senior notes: $367.5 million of 2030 notes repurchased for $322.9 million and $633.4 million of 2031 notes repurchased for $589.9 million — capturing $88 million in value through a ~9% discount. The transaction cut MARA's total convertible debt from approximately $3.3 billion to $2.3 billion, a 30% reduction. MARA retains 38,689 BTC post-sale. Shares rose 10% on the announcement, according to CoinDesk.
Bitdeer — Liquidated its entire bitcoin treasury to zero by late February 2026. The company entered the year with roughly 2,000 BTC, which fell to 1,530 BTC by end of January and 943.1 BTC by February 13 before complete liquidation. On February 21, Bitdeer mined approximately 184 BTC and sold the entire batch alongside its remaining 943.1 BTC reserves when Bitcoin traded between $65,000 and $68,000. The company simultaneously announced a $43.7 million equity offering and a convertible note agreement worth up to $325 million to fund AI/HPC expansion, per Yahoo Finance.
Core Scientific — Sold approximately 1,900 BTC for $175 million in January 2026, having held 2,537 BTC ($222 million) at year-end 2025. The company disclosed on its earnings call that it expects to sell "substantially all" remaining bitcoin holdings in 2026, with the majority of sales in Q1. Core Scientific has signed over $10 billion in AI hosting contracts, anchored by an $8.7 billion, 12-year deal with CoreWeave, according to The Block.
Riot Platforms — Sold roughly $200 million in bitcoin during the final two months of 2025, treating BTC as a "funding tool rather than a passive reserve." Riot sold nearly 1,100 BTC to finance its Rockdale facility acquisition and signed an AI infrastructure lease deal with AMD in January 2026, per CoinDesk.
Bitfarms — Holdings declined from a peak of 3,301 BTC to 1,827 BTC. The company announced on February 6 its plan to redomicile from Canada to the United States and rebrand as "Keel Infrastructure," with a shareholder vote scheduled for March 20.
The CoinShares Q1 2026 Bitcoin Mining Report documents the economic pressure driving the exodus:
The underlying math: Bitcoin is down 46.5% from its all-time high of $126,198 reached in October 2025, while mining difficulty peaked at 155.97 trillion following a +6.31% adjustment on October 29. The gap between production cost and market price has not been this wide since the post-FTX period of late 2022.
The economic case for converting mining infrastructure to AI compute is driven by measurable revenue differentials:
The conversion is not without cost. Retrofitting mining sites for AI/HPC runs $8-10 million per megawatt, and a mining site rated at 55 MW typically delivers only 25-30 MW of critical IT load after adding redundancy, liquid cooling, and higher-tier infrastructure — a 45-55% capacity reduction. However, Bitcoin miners hold a structural advantage: they already have grid connections, power purchase agreements, and permitting in place. GPU Lease Index estimates this enables 60-70% faster deployment compared to greenfield data center builds.
The miner sell-off occurs against a broader crisis in corporate bitcoin holdings. According to BitcoinTreasuries.net data cited across multiple outlets in March 2026:
Specific corporate exposure:
| Company | BTC Held | Avg. Cost Basis | Approx. Unrealized P/L | |---------|----------|----------------|----------------------| | Strategy (MSTR) | ~720,737 | ~$75,985 | -$6B (est. late March) | | Metaplanet | 35,102 | ~$97,000 | ~-31% below basis | | MARA Holdings | 38,689 (post-sale) | Varies | Reduced exposure |
Strategy, the largest corporate Bitcoin holder, reported unrealized losses escalating through Q1 2026: surpassing $2 billion in early February, reaching $4.6 billion when BTC fell below $70,000 in mid-February, and approximately $6 billion by late March. The company maintains total debt exceeding $8.2 billion, according to filings. Despite the losses, Strategy continued purchasing — its largest single acquisition of 22,305 BTC occurred on January 20.
The miner exodus is leaving measurable marks on the Bitcoin network:
The difficulty decline creates a self-correcting mechanism: as less efficient miners exit, remaining operators benefit from reduced competition, potentially restoring profitability for those who remain. However, the structural nature of the AI pivot — converting physical infrastructure away from mining permanently — suggests some hashrate may not return even if Bitcoin prices recover.
The mining sector's liquidation creates a stark strategic divergence. On one side: miners selling BTC, restructuring debt, and converting facilities to AI. On the other: Strategy continues buying, having accumulated roughly 720,737 BTC with $8.2 billion in debt.
The strategies reflect fundamentally different business models. Miners are commodity producers — they face variable costs (electricity, hardware depreciation, maintenance) against volatile revenue (BTC price × hash price). When production cost exceeds market price, they face the same liquidity pressures as any commodity producer operating below breakeven.
Strategy operates as a leveraged bitcoin investment vehicle. It has no mining costs, no hash price exposure, and no competing use for its capital infrastructure. Its risk is concentrated in the gap between its average cost basis (~$75,985) and market price, plus its ability to service $8.2 billion in debt.
The market is pricing these strategies differently. MARA shares rose 10% on its $1.1 billion sale announcement. Bitfarms surged 16% on its Keel Infrastructure rebrand. The market is rewarding miners for selling bitcoin and punishing them for holding it.
The Q1 2026 miner sell-off is not a panic liquidation. It is a rational capital reallocation driven by a measurable gap between bitcoin mining economics and AI compute economics. When AI workloads generate multiples of mining revenue on the same infrastructure, and when production cost exceeds market price by $19,000 per coin, the financial case for conversion is arithmetically clear.
The implications for Bitcoin's network security deserve scrutiny. Permanent infrastructure conversion removes hashrate that does not return with price recovery. The difficulty adjustment mechanism compensates for this — block times self-correct, and remaining miners benefit from reduced competition. But the network is operating at roughly 90% of its peak hashrate, and the direction is downward.
For corporate bitcoin treasury strategy more broadly, the data presents a sobering benchmark: 77.4% of public company holdings are underwater. The mining sector's response — sell BTC, restructure debt, and redeploy capital to higher-yielding infrastructure — may represent the most economically rational corporate bitcoin strategy available when hash price sits at post-halving lows and AI contract revenue offers demonstrably superior returns per unit of deployed power.
