Bitcoin miners’ real prize is power as AI reshapes mining

Summary

Cheap power and grid-ready campuses built for Bitcoin mining are increasingly more valuable for AI hosting than for ASIC mining. Fidelity says this shift could flatten Bitcoin hash-rate growth as major miners redirect capacity into higher-priced hyperscaler contracts. Two deals set the benchmark: Cipher Mining signed a roughly $5.5 billion, 15-year AWS lease for 300 MW, and IREN signed a roughly $9.7 billion, five-year Microsoft GPU cloud contract. The 2024 halving, rising power costs, and weak hash prices have squeezed miner margins, pushing public miners toward AI as a revenue hedge. CoinShares estimates public-miner AI/HPC contracts topped $70 billion by early 2026, with AI potentially becoming most of revenue by year-end. Fidelity’s crossover model says contracted AI hosting now outcompetes most 20–25 J/TH fleets unless BTC price or fees rise sharply. Bitcoin’s difficulty adjustment will absorb hash-rate exits, but power campuses may be permanently reallocated to AI, splitting the sector into AI landlords and lower-cost Bitcoin miners.
