Amazon reported $599 million in net unrealized gains from fair-value measurements of its energy contracts for the six months ended June 30, 2026. A fair-value measurement is an accounting estimate of what a contract is worth at a reporting date; an unrealized gain is recorded before it is settled in cash. Amazon’s Form 10-Q says these measurements do not affect cash flows.
In a report published October 10, Greg Kim of The Seattle Times linked the gain to rising electricity prices. Amazon’s filing describes the factors used to value the contracts and says the gain primarily affected Amazon Web Services (AWS).
What the $599 million figure covers
The six-month total includes $551 million in net unrealized gains for Q2 2026. The quarterly figure is part of the six-month amount, not an additional gain. Amazon records these fair-value changes in “Technology and infrastructure” operating expenses, with the impact primarily in AWS.
The accounting gain is not cash received from selling electricity or a realized saving on power bills. Amazon says the valuation itself does not affect cash flows. Separately, if operational variability leaves electricity consumption below committed quantities, the contracts may require Amazon to make or receive net cash payments.
The long-term contracts behind the valuation
As of June 30, 2026, approximately 270 million megawatt-hours of energy-contract quantities were subject to derivative fair-value measurement. Their weighted-average remaining duration was about 15 years, and most of those quantities were scheduled for delivery more than nine years later. Some contracts extend as long as 20 years.
That time horizon matters because the value of a contract can change before the electricity is delivered. For more liquid periods, Amazon’s valuation uses inputs including electricity futures prices, forward capacity auctions and risk-free interest rates. Those market inputs help determine the accounting estimate; they are not the same thing as a cash payment.
Why long-dated valuations involve more judgment
For periods beyond roughly four to six years, Amazon says trading data are significantly thinner or absent. Management assumptions therefore have a significant role in valuing those longer-dated contracts, which Amazon classifies as Level 3 fair-value measurements.
The $599 million figure combines measurements across contracts with long remaining durations, rather than describing a single electricity sale. The filing’s valuation method accounts for market inputs where available and management assumptions for periods with less trading data.
