Bitcoin miners sell BTC to fund AI

TLDR

Bitcoin mining companies are increasingly selling part of their BTC treasuries to finance a pivot into AI and high performance computing (HPC) data centers.

1. Public miners like MARA, Core Scientific and others have sold tens of thousands of BTC while signing over 70 billion dollars of AI and HPC contracts.
2. This shift is driven by broken mining economics, with average cash costs near 79,995 dollars per BTC versus prices around 68,000 to 70,000 dollars, while AI workloads pay more for the same power.
3. Near term, this adds miner sell pressure and some hashrate risk, but it also turns mining stocks into hybrid AI infrastructure plays rather than pure Bitcoin proxies.

Deep Dive

1. How Big The Pivot Is

Analysts now describe a broad industry transition where listed miners are becoming AI data center landlords and selling BTC to fund that change. A CoinDesk analysis notes that public miners have signed over 70 billion dollars of AI and HPC contracts and are "selling their BTC to fund the transition" as margins turn negative for many operators.

MARA Holdings sold about 15,000 BTC for 1.1 billion dollars in March to buy back debt and free capacity to expand into AI and digital infrastructure, leaving roughly 38,700 BTC on its balance sheet as it positions beyond pure mining. Other miners such as Core Scientific sold around 1,900 BTC to fund AI data center buildout, while firms like Bitdeer, Riot and Bitfarms have also liquidated significant treasuries to finance power and GPU capacity.

2. Why Mining Economics Broke

CoinShares data cited by multiple outlets shows public miners weighted average cash cost at roughly 79,995 dollars per BTC in Q4 2025, while BTC traded around 68,000 to 70,000 dollars. That implies a loss of about 19,000 dollars on each coin produced before overhead.

At the same time, "hash price" (revenue per unit of hashrate) fell to around 29 to 33 dollars per PH per day, and energy costs stayed high, leading to three consecutive negative difficulty adjustments and clear signs of miner stress. Reports comparing returns suggest Bitcoin mining generates roughly 57 to 129 dollars per megawatt in revenue, while AI data centers can earn 200 to 500 dollars per megawatt servicing large language models.

3. Impact On Bitcoin And Stocks

For Bitcoin, stepped up miner selling is an additional source of supply, but there are offsets. CoinShares estimates public miners have reduced their holdings by over 15,000 BTC so far, while ETFs and other buyers still absorb large flows. Network hashrate has pulled back from record highs, yet projections still see hashrate growing over the next couple of years if price recovers.

For mining equities, this is a regime change. Companies like MARA, Core Scientific, IREN and Hut 8 are being valued increasingly on long term AI and HPC revenue streams rather than purely on BTC price beta, with some projected to derive up to 70 percent of revenue from AI by 2026. That can make them less direct proxies for BTC and more like power-plus-data-center businesses with crypto optionality.

Conclusion

Bitcoin miners selling BTC to fund AI is less a betrayal of Bitcoin and more an economic pivot from unprofitable block rewards to higher yielding compute contracts. This raises short term questions around miner sell pressure and hashrate, but it also spreads Bitcoins original power infrastructure into the broader AI economy, while turning mining stocks into hybrid bets on both digital energy and BTC rather than clean price trackers.
