4-bullet brief | narrative

Polymarket prices 29% on Iran agreeing to end uranium enrichment by December 31, resolving via uma_oracle.
IAEA inspection visits represent a procedural step, and the market is not treating this as a near-certain path to full enrichment cessation.
The companion Polymarket contract on Iran ending enrichment by June 30 sits at only 2%, confirming the market sees any deal as a second-half-2026 possibility at best.
Resolves via uma_oracle on public agreement announcement; the 27-percentage-point gap between June 30 (2%) and December 31 (29%) captures the market's view that talks will be slow.
