"We are no longer a Bitcoin company." — Ben Gagnon, CEO, Bitfarms
The largest publicly traded Bitcoin miners in the world are liquidating their Bitcoin treasuries and converting their data centers to serve artificial intelligence workloads. In Q1 2026 alone, public miners have sold over 15,000 BTC — worth more than $1 billion — to finance what the industry is calling "The Great Mining Exodus." Core Scientific, Bitfarms, Riot Platforms, MARA, Hut 8, TeraWulf, Bitdeer, and others have collectively announced over $43 billion in AI and high-performance computing (HPC) contracts, signaling a structural abandonment of Bitcoin mining as a primary business.
The economics are stark. Post-halving mining costs have surged to approximately $137,800 per BTC on a fully loaded basis, while Bitcoin trades near $68,000 — meaning most miners are producing coins at nearly double the market price. Meanwhile, AI colocation contracts offer 80–90% operating margins with 15-year revenue guarantees from hyperscalers like Google and AMD. For corporate boards answering to shareholders, the math is no longer debatable.
But this exodus carries a profound externality: Bitcoin's network hashrate has dropped 12–15% from its October 2025 highs, the steepest decline since China's mining ban in 2021. As miners repurpose power infrastructure for GPU clusters, the hashrate that secures $1.3 trillion in Bitcoin market capitalization is quietly eroding — raising fundamental questions about whether the network's security model can survive the AI gold rush.
At least nine publicly traded Bitcoin mining companies have announced plans to pivot partly or wholly to AI and HPC infrastructure: Riot Platforms, Bitfarms, TeraWulf, IREN, CleanSpark, Hut 8, Bit Digital, Marathon (MARA), and Cipher Mining. Core Scientific, once the largest publicly traded Bitcoin miner in North America, has effectively exited mining entirely.
CoinShares estimates that mining revenue will fall from approximately 85% of total sector revenue in early 2025 to under 20% by the end of 2026 for companies that have secured AI contracts. This is not a gradual evolution — it is an industry-wide phase transition occurring over roughly 18 months.
Bitfarms made the sharpest rhetorical break. In February 2026, CEO Ben Gagnon declared the company was "no longer a Bitcoin company," rebranding it as an "infrastructure-first owner and developer for HPC/AI data centers across North America." The company filed to convert its Washington State cryptomine into a GPU-as-a-Service facility, projecting that the single conversion could generate more net operating income than Bitfarms had ever produced from Bitcoin mining.
Bitdeer went even further: by February 20, 2026, the company had reduced its Bitcoin holdings to zero — selling every last satoshi to fund data center conversions across the U.S., Malaysia, and Europe, where it is deploying NVIDIA GB200 NVL72 systems for AI workloads.
The April 2024 halving cut the block subsidy from 6.25 to 3.125 BTC, slashing miners' guaranteed per-block revenue by 50%. While Bitcoin's price initially rallied above $90,000 in late 2024, the subsequent correction to $68,000 has collided with surging network difficulty and rising energy costs to create an economic crisis:
| Metric | Value | |--------|-------| | Average cash cost to mine 1 BTC | ~$74,600 | | Fully loaded cost (incl. depreciation, SBC) | ~$137,800 | | Bitcoin spot price (March 2026) | ~$68,000 | | Hash price | ~$35/PH/s/day | | Hash price decline since Q3 2025 | -35% |
Bitcoin trades roughly 20% below its average cash production cost and more than 50% below the fully loaded cost. Hash price — the revenue per unit of computational power — has collapsed from approximately $55/PH/s/day in Q3 2025 to $35/PH/s/day, a level that renders all but the most efficient operations unprofitable.
JPMorgan reported that Bitcoin's network hashrate fell for two consecutive months in late 2025/early 2026, with daily mining revenue dropping to yearly lows of $28 million in late January. Only miners with electricity costs below $0.06/kWh and next-generation ASICs operating under 20 J/TH have a viable path to sustained profitability.
Against this backdrop, the AI infrastructure opportunity has proven irresistible. Hyperscalers desperate for power capacity have handed Bitcoin miners something they never had: long-term, guaranteed revenue with institutional counterparties.
Hut 8 signed a 15-year lease agreement with Fluidstack — backed by a financial guarantee from Google — worth approximately $7 billion for 245 MW of AI computing capacity at its River Bend campus in Louisiana. The deal includes expansion potential to 2,300 MW, which could swell the total lease value to $17.7 billion. Hut 8 CEO Asher Genoot called it "the first domino to fall."
Riot Platforms reported record annual revenue of $647.4 million in 2025 (up 72% from $376.7 million in 2024), and its AMD data center lease commenced operations in January 2026 with an initial 25 MW phase. Activist investor Starboard Value argues that Riot's 1.7 GW of available power capacity in Texas could support AI data centers generating more than $1.6 billion in annual EBITDA — a figure that dwarfs its mining economics.
Core Scientific secured $500 million from Morgan Stanley (with an accordion feature to $1 billion) to finance its AI expansion, and has signed over $10 billion in cumulative AI hosting contracts. The company plans to liquidate substantially all of its remaining Bitcoin holdings in Q1 2026.
MARA partnered with Starwood Capital Group in a joint venture to transform its existing mining sites into next-generation AI/HPC data centers, leveraging its portfolio of over 53,000 BTC (valued at approximately $4.7 billion at late-2025 prices) and established power infrastructure.
The combined contract pipeline across these companies exceeds $43 billion — a staggering sum that exposes the economic gulf between mining Bitcoin at a loss and hosting AI compute at 80–90% operating margins.
The pivot requires capital, and miners are funding it by selling the very asset they were built to produce. The treasury liquidation data tells a stark story:
| Company | Peak BTC Holdings | Current BTC Holdings | BTC Sold | |---------|-------------------|---------------------|----------| | Core Scientific | 2,537 | ~637 | ~1,900 | | Bitdeer | ~1,200 | 0 | ~1,200 | | Bitfarms | 3,301 | 1,827 | ~1,474 | | Industry Total (public miners) | — | — | 15,096+ |
Core Scientific sold approximately 1,900 BTC in January alone for $175 million (at ~$92,100 average), and has signaled that substantially all remaining holdings will be monetized during Q1 2026. Bitdeer emptied its entire treasury. Across the public mining sector, the total reduction from peak holdings exceeds 15,096 BTC.
Bloomberg reported on March 4, 2026 that the AI boom is spurring a broader "Bitcoin sales threat" from miners still holding a collective $8 billion in BTC — suggesting the liquidation wave is far from over.
The exodus creates a problem that no corporate earnings call can address: who secures the Bitcoin network?
Bitcoin's hashrate dropped approximately 12–15% from its October 2025 highs, according to CryptoQuant — the most significant sustained decline since China banned mining in 2021. While a portion of this decline was exacerbated by Winter Storm Fern in January 2026 (which temporarily knocked U.S. mining operations offline), the structural cause is clear: miners are physically converting ASIC facilities into GPU data centers for AI workloads. That infrastructure is not coming back.
The security implications are material. A lower hashrate directly reduces the economic cost of a 51% attack: as hashrate falls 15%, the theoretical cost of attacking the network falls proportionally. For a network securing $1.3 trillion in value, this is not an abstract concern.
Moreover, the geographic concentration of remaining hashrate in U.S. facilities — now vulnerable to weather events, grid instability, and regulatory shifts — creates a single point of fragility that Bitcoin's decentralized architecture was specifically designed to avoid.
The network's difficulty algorithm will adjust downward, eventually reaching a new equilibrium. But the question is whether that equilibrium provides sufficient security at current valuations, or whether Bitcoin's security budget — funded primarily by the diminishing block subsidy and still-modest transaction fees — has entered a structural deficit that the market has yet to price.
Not everyone is leaving. The Trump family-backed American Bitcoin (ABTC) purchased 11,298 ASIC miners in March 2026, expanding its fleet by 12% to 28.1 EH/s of owned hashrate. Eric Trump, the company's co-founder and chief strategy officer, framed the move as a patriotic bet: "As Bitcoin matures, the priority is clear: grow American-owned, professionally operated hashrate."
ABTC's expansion is a calculated contrarian play: as competitors exit, difficulty drops, and the remaining miners capture a larger share of block rewards. The company's new machines — operating at 13.5 J/TH efficiency — are among the most competitive hardware deployed today. At current difficulty and prices, the added 3.05 EH/s could produce approximately 515 BTC annually, generating roughly $35 million in gross revenue.
CleanSpark has also maintained a mining-first posture, though it too has begun exploring HPC optionality at certain sites.
The contrarian thesis is simple: if enough miners leave, difficulty falls, margins improve, and the survivors inherit a larger share of a smaller pie. It is a bet that Bitcoin's price will eventually recover above production costs — and that the AI pivot will prove to be a case of selling low on the most asymmetric asset in crypto.
The exodus is structural, not cyclical. Over $43 billion in signed AI contracts with 10–15 year terms means this infrastructure is not returning to Bitcoin mining. The industry's largest players have made irreversible capital allocation decisions.
Mining economics are broken at current prices. With fully loaded production costs at $137,800 and Bitcoin at $68,000, mining is a negative-margin business for most operators. Only miners with sub-$0.06/kWh power and next-gen ASICs remain viable.
Bitcoin's security model faces a genuine stress test. A 12–15% hashrate decline, increasing geographic concentration, and a shrinking security budget funded by a diminishing block subsidy create a vulnerability the market has not yet priced.
The AI infrastructure opportunity is real. Hyperscaler-backed contracts with 80–90% operating margins and guaranteed revenue represent a fundamentally different risk profile than volatile mining economics.
Contrarian miners may be the biggest winners — or losers. If Bitcoin's price recovers, those who stayed (like ABTC) inherit an outsized share of block rewards. If it doesn't, they are the last operators standing in a structurally unprofitable industry.
The Great Mining Exodus is the most consequential structural shift in Bitcoin's 17-year history. For the first time, the economic incentives that secured the network — the alignment between miners' profit motive and Bitcoin's security requirements — are being severed by a more profitable external opportunity. Bitcoin miners built the largest single-purpose computing infrastructure in human history. Now they are repurposing it for artificial intelligence.
The market is treating this as a corporate strategy story. It is, in fact, a network security story. Bitcoin's block subsidy will halve again in 2028, further compressing the revenue available to attract hashrate. If transaction fees do not grow substantially — and there is little evidence they will at current adoption rates — Bitcoin will face a security budget that cannot sustain its valuation.
The miners who are leaving understand something the market has not yet internalized: the era of subsidized security is ending. What replaces it remains an open question — and for a $1.3 trillion asset, it is the most important question in crypto.
