Market context

The Strait of Hormuz handles roughly one-third of global seaborne oil trade, yet daily transit volumes fluctuate significantly based on seasonal demand, geopolitical tensions, and shipping route economics. The 11% probability reflects market scepticism that a single day will see transit calls reach the specified threshold between now and May 2026—a notably low confidence level suggesting traders expect either sustained suppression of traffic or that the bar has been set substantially above typical daily averages.

Historical data from IMF Portwatch shows daily arrivals in the Strait typically range between 15 and 35 vessels, though spikes above 40 occur during seasonal peaks and periods of route concentration. The 2022 energy crisis and subsequent volatility demonstrated how quickly transit patterns can shift; however, the current 11% reading implies the market is pricing in either a threshold well above historical norms or a structural expectation of reduced throughput. Comparable choke-point markets (Suez Canal transits, Panama Canal lockages) have shown that single-day records require either exceptional demand confluence or supply-chain disruption forcing rerouting.

Traders should monitor two near-term catalysts: announcements regarding Iran sanctions policy, which directly influence routing decisions and vessel clustering, and seasonal demand data from major Asian refineries entering their maintenance cycles. Recent OPEC production adjustments and any escalation in Red Sea shipping disruptions would compress alternative routes and concentrate Hormuz traffic. IMF Portwatch publishes daily figures with a lag of 2–3 days, meaning resolution could occur rapidly once conditions align, though the extended settlement window to May 2026 suggests the market expects such alignment remains unlikely.

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.
