Market context

The Bab el-Mandeb Strait, a 33-kilometre chokepoint between Yemen and Djibouti, has experienced sustained disruption since Houthi attacks on commercial shipping intensified in late 2023. The market tests whether transit volumes will collapse to 10 or fewer vessels per day (measured as a 7-day moving average via IMF PortWatch data) by April 2026. Current crowd pricing at 0% YES reflects the strait's continued operation despite attacks: even during peak disruption phases in 2024, daily transits rarely fell below the 10-vessel threshold, with shipping companies routing around the Cape of Good Hope rather than ceasing passage entirely.

Historical precedent suggests complete closure is structurally difficult. The 2011 Suez Canal blockage following the Arab Spring saw transits remain above 10 daily; the 2021 Ever Given incident briefly halted the Suez but involved physical obstruction rather than security threats. Houthi attacks have killed crew members and damaged vessels, yet insurers and operators have adapted through convoy systems, military escort coordination, and rerouting rather than abandonment. The 0% probability reflects this adaptive capacity: even maximum historical attack frequency has not driven daily transits below 10.

Traders should monitor Houthi capability escalation—particularly claims of anti-ship ballistic missiles or coordinated multi-vector attacks—and any major shipping company announcements of permanent route abandonment. Recent reporting from Lloyd's List and Splash247 indicates marginal increases in Bab el-Mandeb traffic through 2024 as operators normalised operations. Geopolitical escalation involving direct US-Houthi military engagement or regional conflict expansion could alter risk calculus, though even these scenarios have not historically produced the sustained, near-total closure this market requires.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
