Vitalik Buterin analyzed the cost structures of Bitcoin mining and AI inference in an October 17, 2026, post on X. He noted that while Bitcoin mining expenses are split between hardware and electricity, AI inference costs are primarily driven by hardware investments.
The estimated cost to mine one Bitcoin is approximately $93,700. Of this, $37,600 (40%) covers hardware capital expenditure, while electricity accounts for $40,600 (43.3%). Consequently, miners are highly sensitive to power costs and market volatility.
In contrast, AI inference costs roughly $26,260 per GPU-year, with hardware capital expenditure making up $19,900 (76%). Electricity represents only 4% to 4.8% of the total, or between $1,050 and $1,260, making power expenses a minor factor for AI operators.
Facility costs also differ significantly. Building a Bitcoin mining site costs between $700,000 and $1 million per megawatt, whereas AI infrastructure requires approximately $20 million per megawatt. This highlights the distinct capital commitments required for each sector.
