Vitalik Buterin contrasts Bitcoin’s power costs with AI’s 76% capital share

Ethereum co-founder Vitalik Buterin has compared Bitcoin mining with AI inference, sharing cost estimates that put electricity at 45.9% of mining expenses and computing capital expenditure at approximately 76% of inference costs. Summary Electricity represents 45.9% of Bitcoin mining costs in the comparison Buterin shared. Computing capital expenditure accounts for approximately 76% of the AI inference estimate. Both tables include cooling, power equipment, and financing within computing capital expenditure. US operators have pursued AI facilities through customer leases, borrowing and crypto treasury sales. In an Oct. 17 X post, Buterin described Bitcoin mining costs as split roughly evenly between computing investment and electricity, while calling AI inference almost completely dominated by computing capital expenditure. Fun fact of the day: Bitcoin mining cost is split about 50/50 between compute capex and electricity. Meanwhile, AI inference is almost completely dominated by compute capex. pic.twitter.com/PCFKZSuNRw— vitalik.eth (@VitalikButerin) October 17, 2026 Bitcoin electricity costs approach half of the estimated total Buterin’s post draws a distinction between the spend...
