Resolution criteria on PolyGram: This market will resolve to “Yes” if IMF Portwatch publishes a 7-day moving average of transit calls (“Arrivals of Ships”) for the Strait of Hormuz equal to or above 60 for any date between market creation and December 31, 2026. Otherwise, this market will resolve to “No”. Daily transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. Ships not reported by IMF Portwatch will not be considered. This market will resolve as soon as IMF Portwatch publishes a 7-day moving average of transit calls equal to or above the specified level, or once data has been published for the final date in the specified period and no such value has been published.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Strait of Hormuz traffic returns to normal by December 31? | 80% YES | 21% NO |
The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits, has experienced significant disruptions since late 2023 due to Houthi attacks on shipping and subsequent international military responses. The market tests whether daily transit volumes—measured as a seven-day moving average of arriving ships across container, tanker, bulk, and general cargo categories—will recover to 60 or more calls per day by year-end 2026. This threshold represents a return to pre-disruption baseline traffic levels, as tracked by IMF Portwatch data.
Historical precedent suggests major chokepoint disruptions typically resolve within 18–36 months. The 2011 Suez Canal blockade saw traffic normalisation within weeks following clearance operations, whilst the 2022 Russia-Ukraine conflict's impact on Black Sea shipping persisted for over a year before partial recovery. The Strait of Hormuz presents a more complex case: transit volumes have already partially rebounded from 2024 lows, with some days exceeding 50 calls, yet sustained normalisation depends on de-escalation of regional tensions rather than physical obstruction removal. The 80% implied probability on Polymarket's order book reflects trader confidence in recovery within the 24-month window, pricing in the likelihood that either security conditions improve or shipping routes stabilise at elevated levels despite ongoing risks.
Key catalysts include announcements regarding Houthi ceasefire negotiations, US naval posture shifts in the region, and insurance premium adjustments that affect routing decisions. Traders should monitor monthly IMF Portwatch releases and shipping industry reports from sources like Lloyd's List for early signals of sustained traffic recovery.
The Strait of Hormuz is a waterway between the Persian Gulf and the Gulf of Oman. On the north coast lies Iran, and on the south coast lies the Musandam Peninsula under the Musandam Governorate of Oman, with a portion of the southwest of the peninsula under the United Arab Emirates. The strait is about 104 miles long, with a width varying from about 60 mi to
The Battle of the Strait of Hormuz was fought in August 1553 between an Ottoman fleet, commanded by Admiral Murat Reis, against a Portuguese fleet of Dom Diogo de Noronha. The Turks were forced to retreat after clashing with the Portuguese.
Shipping traffic through the Strait of Hormuz, a major maritime choke point for world energy trade, has been largely blocked by Iran since 28 February 2026, when the United States and Israel launched an air war against Iran and assassinated its supreme leader Ali Khamenei. In retaliation, Iran launched missile and drone attacks on Israel, US military bases,
