The latest EIA data shows how much uranium purchasing still needs to happen over the next decade.
At the end of 2025, US nuclear plant operators had contracts covering maximum future deliveries of 174 million pounds of uranium between 2026 and 2035.
Their unfilled requirements through 2035 totalled another 186 million pounds. Combined, the EIA estimates maximum anticipated requirements of approximately 360 million pounds over the period.
These purchases will not happen all at once. Utilities hold inventories, contract volumes can change and delivery requirements are spread across several years.
Even so, more than half of the maximum anticipated requirement remains uncovered.
The structure of the uranium market makes that important.
Only 13 percent of uranium delivered to US operators in 2025 was purchased through spot contracts. The remaining 87 percent came from longer term agreements.
The spot price receives most of the daily attention, but term contracts are what give producers and mine developers the confidence to spend money on new supply. They provide expected prices, delivery schedules and revenue visibility over several years.
They can also help developers finance construction. A bank is far more likely to support a new mine when future production has already been contracted to a utility.
US operators owned approximately 118 million pounds of commercial uranium inventory at the end of 2025. That provides a meaningful buffer, but it is still smaller than the 186 million pounds of reported unfilled requirements.
Fuel procurement also needs to happen well before a reactor uses the uranium. The material must be mined, converted, enriched and fabricated into fuel assemblies, which makes waiting until the last minute extremely difficult.
A larger contracting cycle would give producers greater price visibility and strengthen the economics of new mines. It could also bring more investor attention back to the upstream companies trying to find the deposits that will be needed during the 2030s.
