Bitcoin miners are quietly transforming into AI data-center operators — and they’re selling bitcoin to bankroll the shift.
CoinShares’ Q1 2026 mining report paints a stark picture: publicly listed miners faced a weighted average cash cost of about $79,995 to produce one BTC in Q4 2025, while bitcoin traded in a roughly $68,000–$70,000 range. A recent CoinDesk analysis put miners’ losses at roughly $19,000 per BTC mined. Those economics are pushing miners to reimagine their businesses.
Big bets on AI and HPC
The industry has announced more than $70 billion in cumulative AI and high-performance computing (HPC) contracts among public miners, per CoinShares. Major agreements include:
- CoreWeave’s expanded deal with Core Scientific: $10.2 billion over 12 years.
- TeraWulf: $12.8 billion in contracted HPC revenue.
- Hut 8: $7 billion, 15-year lease for AI infrastructure at River Bend.
- Cipher Digital: a multi-billion-dollar agreement with Google-backed Fluidstack.
These deals are already reshaping revenue mixes. Public miners could see up to 70% of revenue from AI by the end of 2026, up from roughly 30% today. Core Scientific’s AI colocation now makes up 39% of its revenue; TeraWulf is at 27%. IREN is scaling fast with up to 200 MW of liquid-cooled GPU capacity under construction.
Why AI is more attractive
The math favors AI. Mining infrastructure costs roughly $700,000–$1 million per megawatt, while AI infrastructure runs $8 million–$15 million per megawatt — but AI projects promise structurally higher, steadier returns. Hash price — the daily miner revenue per unit of computing power — hit a post-halving low of about $28–$30 per PH/s/day in early March. At those levels, miners using mid-generation rigs need power below $0.05/kWh just to stay cash-profitable. By contrast, AI contracts can offer margins above 85% and multi-year revenue visibility.
Funding the pivot: debt and bitcoin sales
Miners are funding AI builds through heavier leverage and by selling BTC reserves.
Debt examples:
- IREN: $3.7 billion in convertible notes across five series.
- TeraWulf: $5.7 billion in total debt (convertibles and senior secured notes at its compute unit).
- Cipher Digital: $1.7 billion in senior secured notes issued in November, driving quarterly interest expense from $3.2 million (first nine months) to $33.4 million in Q4.
Bitcoin treasury reductions:
- Public miners have trimmed over 15,000 BTC from peak treasuries.
- Core Scientific sold ~1,900 BTC (~$175 million) in January and plans to liquidate most remaining holdings in Q1 2026.
- Bitdeer reduced its treasury to zero in February.
- Riot sold 1,818 BTC (~$162 million) in December.
- Marathon, still the largest public holder with 53,822 BTC, expanded a sales policy in its March 10-K amid pressure on a $350 million BTC-backed credit facility that hit an 87% loan-to-value ratio as prices fell toward $68,000.
Security vs. economics: a growing tension
The pivot raises a structural tension: miners fund higher-margin AI infrastructure by diverting capital — and selling BTC — away from mining. If enough companies reallocate, the network’s security budget (hashrate) shrinks.
Hashrate has already reflected the shift: a peak near 1,160 EH/s in October 2025 slid to roughly 920 EH/s, and the network has seen three straight negative difficulty adjustments — the first such streak since July 2022. The market is pricing in the bifurcation: miners with secured HPC contracts trade at about 12.3x next-12-month sales, while pure-play miners trade at 5.9x — more than double for AI exposure.
Geography and future capacity
The U.S., China, and Russia now account for about 68% of global hashrate, with the U.S. gaining roughly 2 percentage points in Q4 2025. New entrants are appearing: Paraguay and Ethiopia joined the global top 10 thanks to HIVE’s 300 MW project in Paraguay and Bitdeer’s 40 MW site in Ethiopia.
CoinShares’ outlook hinges on BTC price. Their baseline forecasts see network hashrate reaching 1.8 ZH/s by end-2026 and 2 ZH/s by end-March 2027 (a one-month delay from previous projections) — but only if bitcoin recovers to $100,000 by year-end. If BTC stays below $80,000, hash price is likely to fall and hashrate to decline further; a sustained drop below $70,000 could trigger broader miner capitulation — culling capacity and lowering difficulty, which could ultimately help survivors.
Could next-gen miners save mining economics?
New, more efficient miners could help: Bitmain’s S23 series and Bitdeer’s SEALMINER A3 — both under 10 J/TH — are expected at scale in H1 2026. At scale, these machines would roughly halve the energy cost per bitcoin versus mid-generation fleets. But deploying them requires capital many outfits are diverting into AI.
Bottom line
The mining sector is in the middle of its biggest identity shift: from companies that primarily secured the bitcoin network and accumulated BTC, to firms that operate AI data centers and sell bitcoin to fund that buildout. Whether this is a cyclical response to weak BTC prices or a permanent structural change will come down to one variable: bitcoin’s price. A return toward $100,000 could restore mining margins and slow the AI pivot. Persistently lower prices will likely accelerate the transition, potentially transforming the industry for good.
