Strait of Hormuz normal traffic by year-end stays below 30%

Polymarket 27%
record: CMSIG2026090304 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-09-03
4-bullet brief | narrative
  • The Polymarket contract on Strait of Hormuz traffic returning to normal by December 31 sits at 27%, reflecting the market's skepticism about near-term de-escalation.
  • Active US-Iran military exchanges, including Iranian attacks on US bases in Kuwait, are consistent with the market's sub-30% probability on restored waterway traffic.
  • Trump's claim that the US controls the Strait of Hormuz stands in tension with Iran's continued ability to strike regional targets, which the 27% price reflects.
  • Resolution depends on an independently verified return to normal Strait of Hormuz transit volumes by December 31, 2026, with no named resolution source specified.
