Hormuz traffic back to normal by year-end stays near long-shot odds

Polymarket 21%
record: CMSIG2026092601 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-09-26
4-bullet brief | narrative
  • Polymarket puts only 21% on Strait of Hormuz traffic returning to normal by December 31.
  • Iran's seven-day reopening proposal and Trump's reported rejection are consistent with the market's skeptical pricing, no resolution in sight.
  • Houthi drone strikes near Riyadh add a second risk vector, further clouding any near-term Hormuz normalization scenario.
  • The Kalshi contract on US embassy reopening in Iran sits at just 4%, signaling the broader diplomatic gap the market sees between the two sides.
