What compute is made of

A NVIDIA H100 SXM rents for $3.93 an hour and draws 1.96 kWh from the grid to do it. At industrial rates that electricity costs $0.17 4% of the price. The commodities below are real and they move; the price of compute mostly doesn’t move with them.

Billed inside the hour
  • Electricity, US city average
    $0.196$/kWh
    30d −0.5%1y +3.2%

    A consumer average. Data centers buy at industrial and contracted rates well below it — this is the visible public benchmark, not what a provider pays.

Sets the price of the direct input
  • Natural gas, Henry Hub spot
    $2.81$/MMBtu
    30d +3.3%1y −9.9%

    Gas sets the marginal price of electricity across much of the US grid, so it moves power prices before power prices move bills — with a lag of months, through contracts.

Capex — reaches the hour years later
  • Copper
    $13,543$/t
    30d −0.1%1y +38.6%

    Busbar, cabling and cooling loops. It prices the building, not the hour — it reaches a rental price years later through hardware amortization.

  • Aluminium
    $3,158$/t
    30d −8.2%1y +21.2%

    Heat sinks, chassis and racks. Buildout cost, same long lag as copper.

Macro context, not a cost line
  • Crude oil, WTI
    $97.26$/bbl
    30d +16.1%1y +54.5%

    Almost no data-center electricity is made from oil. Macro context, not a cost line.

  • Crude oil, Brent

    The international crude benchmark. Same caveat as WTI.

Why the inputs don’t explain the price

Take everything above at today’s prices and it still accounts for a small fraction of what a GPU-hour sells for. On the H100 SXM, electricity is $0.17 and water at a generous upper bound is $0.011, leaving 95% of the price as everything else — overwhelmingly the cost of the hardware itself, spread over its working life, plus the margin a provider charges for carrying that risk. Which is why a doubling in gas does far less to a rental price than one competitor deciding to discount.

Electricity is priced at EIA Electric Power Monthly (May 2026, preliminary) and grossed up by industry-average PUE — the same sourced inputs the anatomy of a GPU-hour uses. Water has no live market price; see the note there.
