Market context

Polymarket currently prices this contract at 0%, reflecting the crowd's assessment that the Bab el-Mandeb Strait will not see transit volumes collapse to 10 or fewer ships per day (measured as a 7-day moving average) before April 2026. The market hinges on IMF PortWatch data, which publishes shipping arrival figures for the chokepoint connecting the Red Sea to the Indian Ocean. A "Yes" resolution requires that metric to drop to single digits—a threshold that would signal near-total closure rather than the disruption already priced into global shipping.

The Houthi campaign against commercial shipping in the Red Sea began in October 2023 and has persisted through 2024, yet transit volumes have not approached the 10-ship threshold despite sustained attacks and insurance premium spikes. Historical precedent matters here: the Suez Canal blockage in March 2021 (Ever Given incident) saw rerouting rather than closure, and even during peak Houthi operations in early 2024, daily transits remained in the 20–40 range according to shipping data. The market's zero probability reflects this resilience—traders are pricing in the assumption that alternative routes, military escort operations, and commercial incentives will maintain minimum viable traffic.

Catalysts for movement would centre on escalation beyond current attack patterns: a direct hit on critical port infrastructure at Aden or Djibouti, a declared blockade by Houthi leadership, or a geopolitical shift that removes naval protection for convoys. Recent statements from Houthi spokespeople have framed attacks as political messaging rather than total interdiction. The settlement window extends to April 2026, giving 18 months for conditions to shift, but the 0% pricing suggests traders view the threshold as structurally unlikely given demonstrated shipping behaviour under pressure.
