Bitcoin miners are becoming AI companies and selling their BTC to fund the transition
The bitcoin mining industry is undergoing the most fundamental transformation in its history, and the clearest sign isn't the hashrate or the difficulty adjustments.
It's the balance sheets.
CoinShares' Q1 2026 mining report , published this week, reveals that the weighted average cash cost to produce one bitcoin among publicly listed miners rose to approximately $79,995 in Q4 2025.
Bitcoin has traded in the $68,000 to $70,000 band, with a CoinDesk report last week estimating losses of $19,000 per BTC mined.
These numbers aren't sustainable, and the industry knows it.
The response has been a wholesale pivot toward artificial intelligence infrastructure that is reshaping what these companies actually are.
Over $70 billion in cumulative AI and high-performance computing contracts have now been announced across the public mining sector, according to the CoinShares report.
CoreWeave's expanded deal with Core Scientific alone is worth $10.2 billion over 12 years.
TeraWulf has $12.8 billion in contracted HPC revenue.
Hut 8 signed a $7 billion, 15-year lease for AI infrastructure at its River Bend campus.
Cipher Digital has a multi-billion-dollar agreement with Google-backed Fluidstack.
Listed miners could derive as much as 70% of their revenue from AI by the end of 2026, up from roughly 30% today.
Core Scientific's AI colocation revenue already accounts for 39% of its total.
TeraWulf is at 27%.
IREN is at 9% and scaling rapidly with up to 200 megawatts of liquid-cooled GPU capacity under construction.
