Ethereum co-founder Vitalik Buterin compared the economic structures of Bitcoin mining and AI inference in an Oct. 17 X post, arguing that the two computing-heavy industries allocate capital and energy very differently. He said Bitcoin mining cost is split roughly 50/50 between compute capital expenditure and electricity, while AI inference is almost entirely dominated by compute capex.
According to the breakdown Buterin shared, electricity supplied directly to computers costs about $40,600 per BTC, or 43.3% of the total, with other electricity expenses adding $2,400, or 2.6%, bringing the combined electricity share to 45.9%. Computing capital expenditure contributes about $37,600 per BTC, representing roughly 40%, and includes hardware, cooling, power equipment and financing. Additional categories include labor at $3,200, facility rent at about $2,500, and other expenses around $7,400, producing an estimated total of $93,700 per BTC.
For AI inference, the table measured costs per GPU-year and assigned about $19,900, or 76%, to computing capital expenditure. Direct electricity costs came to $1,050, or 4%, other electricity to $210, or 0.8%, labor to $1,400 and facility rent to $900, with other operating costs around $2,800. The listed total was about $26,260 per GPU-year.
The comparison arrives as U.S. operators increasingly link crypto mining infrastructure with AI data center demand. TeraWulf is developing its Justified Data campus in Hawesville, Kentucky, under a 20-year lease with Anthropic for roughly 401 megawatts of critical computing capacity, with revenue estimated at $19 billion over the initial contract term. In October 2025, a TeraWulf subsidiary priced $3.2 billion of senior secured notes carrying a 7.75% annual interest rate and maturing in 2030.
Other companies have also used digital asset sales to fund AI expansion. Quantum Solutions' subsidiary GPT Pals Studio sold 1,000 ETH for $1.903 million to support Japanese AI data center plans, while Hyperscale Data monetized approximately 100 BTC and established a Bitcoin-backed credit facility for construction in Michigan. MARA also disclosed a Texas land acquisition of 1,200 acres intended to support high-performance computing and Bitcoin mining, with initial grid capacity expected by October 2027.
