Strait of Hormuz return to normal by year-end stays unlikely

Polymarket 18%
record: CMSIG2026091105 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-09-11
4-bullet brief | narrative
  • Polymarket prices only 18% on Strait of Hormuz traffic returning to normal by December 31, 2026.
  • Houthi seizure of the Bab al-Mandab is a distinct chokepoint from Hormuz, but the combined shipping disruption signals deepening regional instability that is consistent with the low 18% pricing.
  • Iran hitting a US drone in the Hormuz Strait (Story 27) and 96 vessels diverted adds further evidence the market's skeptical stance reflects current ground truth.
  • Resolves via UMA oracle; settlement requires documented evidence of normal commercial shipping transit volumes through the Strait of Hormuz.
