Uranium plateaus near $86 as a structural supply deficit builds underneath
Spot prices stall on muted utility buying even as mine restarts slip and the long-term reactor-fuel gap widens

Summary
Uranium spot sat near $85.85/lb U3O8 on 23 June 2026, a plateau after the 2024-25 speculative run, with utilities shifting to long-term contracting and muted spot buying. The flat tape masks a tightening physical picture: Canada's McArthur River cut 2025 output on development delays, Kazatomprom signalled a lower nominal 2026 production level, and several in-situ recovery restarts ramped slower than planned. Mine output is running below world reactor requirements, with a deficit forecast to widen over the next decade. Demand-side anchors, SMR orders and AI data-center Electricity load, underpin term prices even as spot stalls. [[Sprott]] calls it "a tale of two markets."
By the numbers
- $85.85/lb, global spot U3O8 indicator, 23 June 2026.
- Decade-long, forecast duration of the building mine-supply deficit vs reactor needs.
- ~10%, Kazatomprom's reduction to nominal 2026 output guidance during 2025.
- McArthur River, Canadian mine that lowered 2025 output on development delays.
Why it matters
Uranium is the upstream chokepoint of the nuclear-fuel cycle. A flat spot price hides concentration risk and a structural deficit; Western utilities re-contracting now set the cost base for the reactor and AI-power buildout for a decade.
What to watch
- Whether term-contract prices decouple further from a stalled spot tape.
- Pace of ISR restarts and McArthur River recovery.
- Sulphuric-acid availability constraining Kazakh ISR output.
