Buterin: AI May Outbid Miners on Power Costs

The cost of mining bitcoin is split roughly evenly between compute hardware and electricity, according to Ethereum co-founder Vitalik Buterin. He added that AI inference, by contrast, is almost entirely a hardware expense.

This distinction matters as miners and AI firms increasingly compete for the same power sites, but the two industries allocate their spending very differently.

What Drives Bitcoin Mining Cost Per Coin?

Buterin posted the observation alongside a cost breakdown. Its line items total roughly $93,700 per coin.

Electricity is the biggest cost. Power fed directly to the machines amounts to $40,600 per coin, or 43.3% of the total. Additional electricity costs $2,400.

Compute capital expenditure (capex) is about $37,600. That includes hardware, cooling, power equipment, and financing, accounting for roughly 40% of the bitcoin mining cost.

Labor, facility rent, maintenance, insurance, taxes, and bandwidth make up the remaining 14% or so. That leaves electricity and compute capex nearly even, at around 46% and 40% respectively.

The table's total exceeds JPMorgan’s recent bitcoin production cost estimate of $85,000.

It also sits above bitcoin's current price, meaning an average miner would not cover its full costs.

Why AI Plays by Different Power Rules

AI inference reverses that ratio, according to Buterin. Running trained models depends heavily on expensive chips, so power accounts for a much smaller portion of each dollar spent.

Therefore, an AI operator can likely tolerate higher electricity prices than a miner can. For miners, power represents a far larger share of the bitcoin mining cost.

That difference is already affecting the market. Many miners hold permitted grid capacity that AI developers cannot build quickly as local data-center restrictions spread.

Some industry observers now question whether AI could push mining out of the most expensive locations entirely.

Others advocate merging the two models. BitMEX co-founder Arthur Hayes, for instance, is building a Bitcoin-style AI mining network that pays GPU owners.

If Buterin's calculation holds, cheap power remains the miner's advantage, while cheap capital benefits AI. The next contest for energy sites may depend less on bitcoin mining cost and more on which sector can finance hardware fastest.
