Bitcoin Miners Reduce Hashrate by 23% While AI Revenue Jumps 52% in Q2 2026

Public Bitcoin miners disclosed a combined reduction of 56 exahashes per second (EH/s) of realized hashrate during the first half of 2026, representing a 15% contraction versus the overall network’s 10% drop. The decline was not a capitulation but a reallocation of power toward AI‑related services.

Revenue Shift Toward AI and HPC

Comparable miners reported a 52% increase in direct HPC and AI revenue in Q2 2026 relative to Q1. For the most advanced participants, AI‑cloud or HPC colocation revenue surpassed the mining revenue that was being phased out.

Capital Expenditure and Cost Structure

Fourteen companies in the latest analysis spent $18.6 billion in a single quarter on AI‑related capex. Six infrastructure providers with recurring HPC revenue had total capex nearly 15 times their combined period revenue, highlighting a significant spending‑revenue gap.

Revenue per Megawatt‑Hour

• Recurring HPC revenue for AI power‑shell providers ranged from $86 to $300 per MWh, with a median of about $180 per MWh.
• CoreWeave’s quarterly deployment cost was estimated at $322 per MWh (range $268–$403).
• Full‑stack AI operators reported higher densities: IREN $807/MWh, HIVE $924/MWh, WhiteFiber $958/MWh, Bitdeer $1,213/MWh.
• Bitcoin mining revenue density: Bitmain Antminer S23 Hyd $179.13/MWh; Antminer S21 Pro $113.45/MWh.
• HPC colocation median $174.90/MWh, closely matching the S23 Hyd revenue density.
• Zcash mining (Z15 Pro) generated $585.61/MWh, roughly three times the S23 Hyd density and temporarily exceeding most HPC agreements.

Comparative Economics

AI‑cloud revenue per MWh is more than five times the Bitcoin mining density for the S23 Hyd and over eight times that of the S21 Pro. However, AI revenue is tied to longer‑term contracts and includes the value of GPUs, networking, software, and risk transfer, whereas Bitcoin mining revenue fluctuates with price, difficulty and fees.

Implications for Miners

The higher revenue per MWh from AI tenants explains miners’ interest in repurposing facilities, while the substantial capex required for AI infrastructure limits the number of miners that can achieve attractive returns.
