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

Polymarket 17%
record: CMSIG2026091806 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-09-18
4-bullet brief | narrative
  • The Polymarket prediction market puts only 17% odds on Strait of Hormuz traffic returning to normal by December 31, 2026.
  • Houthi advances toward Bab el-Mandeb and continued regional escalation are consistent with Polymarket pricing a disrupted waterway through year-end.
  • A separate US Treasury sanction on Iranian crypto exchange BitBank, tied to Hormuz maritime payments, adds further evidence of persistent chokepoint pressure.
  • Resolution: Polymarket settles via its UMA oracle process, requiring verified shipping traffic data.
