Public bitcoin miners shed an estimated 56 EH/s of realized hashrate during the first half of 2026, representing a 15% contraction compared to a 10% network-wide drop. Rather than leaving the compute sector entirely, much of this power was redirected toward artificial intelligence infrastructure.
The shift is evident in financial results. Directly reported HPC and AI revenue among comparable miners rose 52% from the first quarter to the second. For companies furthest along in the transition, Q2 marked the first time AI-related revenue exceeded mining revenue.
Capital Intensity and Revenue Comparison
The conversion to AI infrastructure requires significant investment. Fourteen companies in a recent analysis spent $18.6 billion in a single quarter, with capex running nearly 15 times their combined period revenue among six providers already reporting HPC revenue.
Revenue density varies substantially by model. Infrastructure providers offering powered space generated approximately $86 to $300 per MWh in recurring revenue, with a median around $180 per MWh. Full-stack AI-cloud operators reported significantly higher densities: IREN at approximately $807 per MWh, HIVE at $924, WhiteFiber at $958, and Bitdeer at approximately $1,213 per MWh.
Mining Economics in Context
AI-cloud revenue generates roughly five to eight times the megawatt-hour density of current bitcoin mining. The estimated median AI-cloud revenue of $940.74 per MWh compares with $179.13 per MWh from Bitmain's latest-generation Antminer S23 Hyd.
HPC colocation revenue, at a median of approximately $174.90 per MWh, aligns closely with current bitcoin mining returns. The underlying economics differ significantly: colocation agreements are typically multi-year contracts with pass-through electricity costs, while bitcoin mining revenue fluctuates with price, network difficulty, and transaction fees.
The capital requirements create a fundamental difference in risk profiles. Bitcoin mining hardware can be deployed and monetized quickly into a liquid market, but revenue can decline sharply. AI infrastructure campuses require years of construction and capital deployment but may provide contracted, predictable payments from creditworthy tenants over a decade or longer.
