Hormuz traffic back to normal by year-end hardens above three quarters

Polymarket 78%
record: CMSIG2026061806 | category: momentum-repricing | target: CM-EVT-LCPV825X09 | published: 2026-06-18
4-bullet brief | narrative
  • Polymarket prices 78% on Strait of Hormuz traffic returning to normal by December 31, reflecting confidence the blockade removal is durable over a multi-month horizon.
  • The US military ending the port blockade and the Hormuz reopening are the direct catalysts; the market is broadly consistent with these developments.
  • The near-term contract on Hormuz returning to normal by end of June (CM-EVT-YPW93GCTK6) is at only 18%, revealing the market sees the physical restoration of full traffic as a weeks-long process despite the political breakthrough.
  • Resolves via portwatch.imf.org traffic data; measured shipping flow through the Strait, not political announcements, determines settlement.

The 78% year-end versus 18% end-of-June spread is the key term structure signal: political opening is priced, operational normalization is not yet.llm_judge_cm_signal_v1
