4-bullet brief | narrative

Polymarket prices just 12% on Iran agreeing to end uranium enrichment by December 31, 2026, keeping this a heavy long shot despite intense diplomatic pressure.
Trading volume on this contract surged 3,167% day over day, signaling a large spike in fresh attention as Trump-Iran rhetoric escalated sharply over the weekend.
A companion Polymarket contract on the Iranian regime falling before 2027 sits at only 6%, suggesting markets do not expect military action to produce regime change.
Resolution requires a verified Iranian agreement to halt enrichment; the gap between heated rhetoric and the 12% price reflects deep market skepticism that threats translate to a deal.
