Bitcoin miners invest $5B in AI infrastructure, generating $341M in revenue during first half of 2026

Nine publicly traded miners have collectively poured more than $5B into AI and high-performance computing infrastructure, and that bet returned $341M in combined revenue during the first half of 2026. Several of these companies now generate more income from renting out compute to AI workloads than they do from actually mining Bitcoin. The numbers behind the pivot Cumulative AI and HPC contracts across the public mining sector now exceed $70B, with deal structures often spanning 12 to 20 years. Companies like Core Scientific and TeraWulf now earn more from AI operations than from Bitcoin mining. By the end of 2026, some miners are projected to pull up to 70% of their total revenue from AI-related work. The combined Bitcoin mining hashrate among public operators has dropped between 13% and 21%. These companies are deliberately reallocating power and rack space away from SHA-256 computations and toward GPU-dense AI inference and training clusters. Why miners make surprisingly good AI landlords Both activities share the same fundamental infrastructure requirements: massive amounts of electricity, industrial-scale cooling, and remote locations where land is cheap and power is abundant. ...
