Key facts
- Bitcoin mining costs are roughly 46% electricity and 40% compute capex.
- AI inference costs are approximately 76% compute capex and 4.8% electricity.
- Bitcoin miners can curtail capacity due to variable electricity costs, unlike AI operators.
Ethereum co-founder Vitalik Buterin shared a detailed cost comparison between Bitcoin mining and AI inference, highlighting a key structural advantage for miners in the burgeoning AI hosting market. Buterin's analysis, posted on X on October 17, 2026, revealed that Bitcoin mining costs are split roughly evenly between compute capital expenditure (capex) and electricity, while AI inference is overwhelmingly dominated by compute capex.
For Bitcoin mining, the total cost per BTC mined is estimated at $93,700, with compute capex accounting for about 40% and electricity for 45.9%. In contrast, AI inference costs per GPU-year total around $26,260, with compute capex making up approximately 76% and electricity a mere 4.8%.
This disparity means Bitcoin miners, who often have flexible power contracts, can more easily curtail operations during low hashprice periods. AI inference operators, however, face continuous capex costs regardless of utilization. This has led to a trend of miners pivoting to AI hosting, with companies like Core Scientific, MARA, and Anthropic entering into significant data center and power access agreements.
