Strait of Hormuz traffic returns to normal by September 30?

Platform comparison

Market context

Polymarket’s contract is trading at a **26% YES** implied probability, which fits a market still pricing in a partial but not full normalisation of Strait of Hormuz traffic before the 30 September 2026 settlement date. On Polymarket, buyers are using USDC on Polygon, with the outcome determined by conditional tokens that pay out only if IMF Portwatch’s 7-day moving average of “Arrivals of Ships” reaches **60 or more** at any point before expiry.

That threshold is best read against the post-conflict reset in shipping patterns. Reuters reported traffic at less than 10% of typical volumes in early April, even with a ceasefire, while later reporting from CNBC and the New York Times said flows improved after the US-Iran reopening deal but remained far below pre-war levels and fragile to fresh disruptions.[14][8][13] More recent reports suggest some recovery in tanker movements, including over 20 oil tankers using the route after the June reopening framework, but analysts still described the route as unsettled and dependent on security conditions and mine clearance.[7][3][12]

For traders, the key catalysts are operational rather than abstract: any fresh ceasefire language, naval security assurances, or evidence of mine clearance could lift the 7-day average quickly, while a renewed attack or re-imposed transit restrictions could push it back down.[1][13] IMF Portwatch’s own rolling data will matter more than headlines, because the market resolves on published arrivals, not intentions, and a short burst of sailings will only count if it is sustained enough to keep the average at or above 60. The most relevant near-term dependencies are tanker schedules, insurer willingness to cover the route, and whether ships continue transiting without diversion through alternative Gulf paths.[1][2]
