Strait of Hormuz back to normal by December stays unlikely

Polymarket 18%
record: CMSIG2026091907 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-09-19
4-bullet brief | narrative
  • Polymarket puts 18% odds on Strait of Hormuz traffic returning to normal by December 31, 2026.
  • Houthi territorial gains and continued disruption of Saudi oil exports are consistent with the market's strong skepticism about a near-term normalization.
  • Separately, a US blockade of Iranian ports described in adjacent reporting reinforces the structural disruption narrative underpinning this pricing.
  • Resolution via uma_oracle; the contract's definition of 'normal' traffic levels is the key edge case, as partial recoveries may not meet the threshold.
