Full analysis
The Iran diplomatic track is experiencing a significant repricing this week. The polymarket contract for a permanent peace deal by May 31 (0x0e4a0c937b8934c247) dropped from 10¢ to 5¢ on 8.7 million in volume, indicating near-total loss of confidence in an imminent breakthrough. This cascading pessimism is visible across the term structure: the June 7 contract (0x366f89649caea042c9) fell 5¢ to 16¢, June 15 (0xd86a816093fcd0a0e1) dropped 7¢ to 23¢, and even the longer-dated July 31 contract (0x20af55ab35186377b8) declined 11¢ to 49¢. Only the December 31 contract (0x9769f78cbc95a5ed11) holds above 50¢ at 75¢, down 3¢.
Traders should pay close attention to the Strait of Hormuz blockade dynamics. The 'Trump announces blockade lifted by June 30' contract jumped 8¢ to 70¢ (0x4d0c4865bdecc5f797), suggesting a potential decoupling between a formal peace deal and the immediate blockade resolution. This divergence creates interesting cross-market opportunities.
Key contracts to watch include the nuclear deal by May 31 (0xbeab83146920be8f52) at 6¢ (down 10¢), Iran regime change by May 31 (0x789c947a9415600d30) at 0¢, and Iran agreeing to surrender enriched uranium by May 31 (0xd39905267d79b715f0) at 3¢ (down 2¢). The collapse in short-dated probabilities suggests traders should focus on the June-July contracts for potential value if diplomatic channels are still active.
For oil traders, the WTI crude contracts are directly impacted. The 'WTI ↓ $85' in May contract (0x59a37ea3830d532957) fell a dramatic 43¢ to 0¢, reflecting lower probability of oil price declines as Iran risk persists. However, the broader oil market remains sensitive to any Hormuz developments.
