"The ability for miners to convert to AI is one of the largest infrastructure shifts of this decade." — Adam Sullivan, CEO, Core Scientific
Bitcoin miners have collectively signed more than $70 billion in AI and high-performance computing contracts as of August 2026, turning what was a crypto-native industry into one of the largest sources of AI data center capacity in the United States. The shift is not speculative: Core Scientific now derives 83% of quarterly revenue from AI colocation. Hut 8 holds $26.6 billion in aggregate contracted lease value. IREN has lifted its annualized AI revenue target above $4 billion.
The pivot arrives as mining economics have deteriorated to structurally unprofitable levels. The weighted average cash cost to produce one bitcoin among publicly listed miners rose to approximately $79,995 in Q4 2025, while Bitcoin traded near $68,000 — a loss of roughly $19,000 per coin. Network difficulty has fallen 14% from its 2026 high to 126.23 trillion, and hashrate has declined from a peak of ~1,160 EH/s in October 2025 to ~943 EH/s. Difficulty has now fallen year-over-year for only the second time in Bitcoin's history, after China's 2021 mining ban.
Publicly listed miners have sold more than 15,000 BTC from treasury reserves to finance the transition. Core Scientific liquidated 1,900 BTC for $175 million in January alone. Bitdeer reduced its treasury to zero. The industry that once defined itself by accumulating Bitcoin is now defined by selling it.
The post-halving compression has made Bitcoin mining a losing proposition for most publicly listed operators.
| Metric | Value | Source Period | |--------|-------|-------------| | Avg. production cost per BTC | ~$79,995 | Q4 2025 | | Bitcoin price | ~$68,000–$70,000 | Q1 2026 | | Loss per coin mined | ~$19,000 | Q4 2025–Q1 2026 | | Hashprice | ~$29–$32/PH/s/day | July–August 2026 | | Network difficulty | 126.23T | August 3, 2026 | | Difficulty decline from 2026 high | -14% | YTD |
Hashprice — the dollar revenue per petahash per second per day — sits near all-time lows at approximately $29–$32/PH/s/day. At these levels, only operators running latest-generation ASICs (Antminer S21 XP, S23 Hydro) with electricity costs below $0.055–$0.088/kWh can break even on a cash basis. Older S19-class machines are offline or heading there.
The difficulty adjustment on July 25 came in at -0.74% to 126.23 trillion. The next adjustment, estimated for August 8, projects a modest +0.84% increase. But the broader pattern is clear: 2026 has seen three consecutive negative difficulty adjustments — the first such streak since July 2022 — driven by miners redirecting power capacity from SHA-256 hashing to GPU racks.
The aggregate value of announced AI and HPC contracts across publicly listed Bitcoin miners exceeds $70 billion. The major deals:
| Company | Contract Partner(s) | Value | Duration | |---------|---------------------|-------|----------| | Core Scientific | CoreWeave, AMD | $10.2B + $14B | 12–15 years | | TeraWulf | Various | $12.8B | Multi-year | | Hut 8 | Anthropic, Fluidstack (Google-backed) | $9.8B (Beacon Point) + $7B (River Bend) | 15 years | | IREN | Microsoft, NVIDIA, Perplexity, Figure AI | $9.7B (Microsoft) + $2.8B (cloud services) | Multi-year | | Cipher Digital | Fluidstack (Google-backed) | Multi-billion (undisclosed) | Multi-year |
These are not memoranda of understanding. They are binding leases and colocation agreements with creditworthy counterparties — hyperscalers, chipmakers, and well-funded AI labs. The contract durations, predominantly 12 to 15 years, reflect the capital-intensive nature of data center construction and the long payback periods involved.
Core Scientific's Q2 2026 earnings illustrate the transition in granular detail.
Revenue: $164.2 million, up 109% year-over-year from $78.6 million. AI colocation accounted for $136.7 million — 83% of total revenue — up from $10.6 million in Q2 2025, a 1,190% increase. Digital asset self-mining contributed just $21.5 million, down from $62.4 million a year earlier.
Capacity: The company was billing 437 MW of customer power as of mid-July 2026, with 1.1 GW of total leased capacity. The AMD partnership alone covers up to 2.5 GW across five sites with a base contract value exceeding $14 billion over 15 years.
Profitability: Gross profit reached $70 million (43% margin), and adjusted EBITDA hit $41.1 million. The headline net loss of $1.16 billion was driven almost entirely by a $1.05 billion non-cash warrant revaluation, not by operating deterioration. Capital expenditures surged to $797.5 million in Q2 as build-out accelerated.
CEO Adam Sullivan described the company's Bitcoin mining operations as "essentially in runoff," maintained primarily to satisfy minimum power commitments at legacy sites being converted to AI colocation.
Hut 8 reported Q2 2026 revenue of $74.9 million, with compute revenue (predominantly AI) comprising $72.5 million — 97% of total revenue. The company holds 949 MW of contracted IT capacity with an aggregate base-term contract value of approximately $26.6 billion and expected average annual net operating income exceeding $1.75 billion.
Hut 8 has 1,330 MW of energy capacity under construction across its River Bend (330 MW) and Beacon Point (1,000 MW) campuses, with a total development pipeline of 8,660 MW. The company closed $7.5 billion in investment-grade project financing in a single quarter — two separate bond offerings to fund construction. Liquidity stood at $8.1 billion as of June 30, including cash, restricted cash, and Bitcoin holdings.
CEO Asher Genoot stated: "Commitments of this depth from sophisticated counterparties underscore the strength of a model built to perform repeatedly at scale."
IREN has secured $2.8 billion in cloud services contracts and a separate $9.7 billion deal with Microsoft for 76,000 NVIDIA GB300 GPUs across 200 MW at its Childress, Texas campus. The company raised its 2026 annualized run-rate revenue target for AI cloud services to more than $4 billion, with roughly 85% already under contract. IREN shares jumped nearly 20% on the contract announcements in late July 2026. Its customer list now includes Microsoft, NVIDIA, Perplexity, Figure AI, and Together AI.
The pivot requires capital. Miners are funding it, in part, by liquidating the Bitcoin they once competed to accumulate.
| Company | BTC Sold | Proceeds | Timing | |---------|----------|----------|--------| | Core Scientific | ~1,900 BTC | $175M | January 2026 | | Riot Platforms | 1,818 BTC | $162M | December 2025 | | Bitdeer | Entire treasury | Undisclosed | February 2026 | | Marathon Digital | Authorization to sell from 53,822 BTC reserve | Pending | 2026 |
Collectively, publicly listed miners have reduced their BTC treasuries by more than 15,000 BTC from peak levels. Marathon Digital, the largest public holder with approximately 53,822 BTC (valued at roughly $4 billion), has expanded its policy to authorize sales from its entire balance sheet reserve — though it has not yet executed large-scale disposals.
Core Scientific expects to monetize "substantially all" of its remaining bitcoin holdings in 2026. The company held 2,537 BTC worth $222 million at year-end 2025 and had already sold the majority by Q1.
Bitcoin network hashrate has fallen from a peak of approximately 1,160 EH/s in October 2025 to roughly 943 EH/s — an 18.7% decline. Network difficulty has dropped below year-earlier levels for only the second time in Bitcoin's history. The first occurrence was mid-2021, when China banned cryptocurrency mining and approximately half of global hashrate went offline overnight.
The 2026 contraction is structurally different. Hashrate is not being destroyed by government decree. It is being voluntarily retired as miners redirect power capacity, physical space, and capital expenditure toward GPU-based AI infrastructure that generates higher and more predictable revenue per megawatt.
According to Hashrate Index, contributing factors include: weak mining economics at current hashprice levels, AI/HPC capacity expansion consuming power allocations previously dedicated to mining, Texas power curtailments during summer demand peaks, and Iran-related disruptions affecting a portion of global hashrate.
Some industry forecasts project hashrate recovery to 1.8 ZH/s by year-end 2026, but that estimate is contingent on Bitcoin reaching $100,000 — a price level that would restore positive unit economics for a broader set of operators.
The scale of borrowing to finance the AI pivot introduces concentration risk. Select debt positions across the sector:
These are long-duration, capital-intensive commitments backed by 12- to 15-year revenue contracts. If AI compute demand contracts, or if hyperscaler customers renegotiate terms, miners-turned-data-center-operators face debt service obligations without the revenue streams to match. The structural risk is that these companies have traded Bitcoin's price volatility for AI demand cyclicality — and layered significant leverage on top.
The Bitcoin mining industry is undergoing an identity change. Companies that built their businesses around SHA-256 hashing are rebranding as AI infrastructure providers, selling their Bitcoin treasuries, and taking on billions in debt to build GPU-dense data centers for hyperscalers and AI labs.
The economic logic is straightforward: mining Bitcoin at a $19,000 per-coin loss is not viable. AI colocation generates higher, more predictable revenue per megawatt of power capacity. Core Scientific's 1,190% year-over-year increase in AI colocation revenue demonstrates the magnitude of the gap.
The question is whether the AI compute demand that underpins $70 billion in contracts will persist over 12- to 15-year horizons. Miners have exchanged one form of cyclical risk for another, while adding significant leverage. If the AI infrastructure buildout follows historical technology investment cycles, overcapacity and margin compression are eventual outcomes. For now, the contracts are signed, the GPUs are being installed, and the Bitcoin ASICs are being unplugged.
