A prediction market on Polymarket, with over $27 million in trading volume, is currently pricing in a near-certain 'No' outcome regarding the return of Strait of Hormuz traffic to normal levels by May 31, 2026. The market, which will resolve 'Yes' if the IMF Portwatch 7-day moving average of transit calls reaches or exceeds 60, currently sees the 'Yes' outcome trading at a mere 0.0235, while 'No' stands at 0.9765. This stark pricing reflects the ongoing and severe disruption to one of the world's most critical maritime chokepoints.

The Market at a Glance

The market question asks if the 7-day moving average of transit calls for the Strait of Hormuz will be equal to or above 60 for any date between its creation and May 31, 2026, as reported by IMF Portwatch. Transit calls include various ship types such as container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. The resolution source is the IMF Portwatch data, accessible via their website. This market serves as a real-time gauge of global shipping stability and geopolitical tensions in the Middle East.

Recent Developments and Impact

Shipping traffic through the Strait of Hormuz has been severely impacted since February 28, 2026, following an escalation of conflict involving the United States, Israel, and Iran. Iran has reportedly issued warnings and taken steps to disrupt maritime traffic, leading to a significant decline in vessel transits. Major shipping companies, including Maersk, MSC, CMA CGM, and Hapag-Lloyd, have suspended transits through the strait or rerouted their vessels, citing safety concerns and increased war risk insurance costs. Some reports indicate that traffic through Hormuz was running at approximately 5% of its pre-war average in April.

Adding to the complexity, the ongoing Red Sea shipping crisis, triggered by Houthi attacks, continues to force many vessels to divert around the Cape of Good Hope, further straining global supply chains. Analysts describe the simultaneous disruption of both the Strait of Hormuz and Red Sea routes as the "most severe Middle East supply chain disruption in modern history".

Analysis of Current Odds and Data Points

The current market odds of 0.9765 for 'No' strongly suggest that traders believe it is highly improbable for the 7-day moving average of transit calls to reach 60 by the end of May. This sentiment is well-supported by available data.

According to IMF Portwatch data as of May 17, 2026, the 7-day moving average of transit calls for the Strait of Hormuz stood at a mere 6.29, with daily transit calls at 2.00. This figure is dramatically below the 60-call threshold required for a 'Yes' resolution. While a recent report from May 26, 2026, indicated that Iran's Islamic Revolutionary Guard Corps (IRGC) Navy reported 25 vessels transiting the Strait of Hormuz in a 24-hour period with Iranian authorization, even this number, if sustained, would result in a 7-day average of 25, falling far short of the 60-call target.

The IMF Portwatch platform itself acknowledges "Trade disruptions in the Strait of Hormuz due to attacks on commercial ships," noting "Reduced traffic since February 28, 2026 — Ongoing". The platform also cautions users about reports of GPS jamming, AIS spoofing, and vessels going dark in the region, advising care when using the data. Given the significant gap between the current reported traffic and the market's threshold, a rapid and sustained increase to an average of 60 vessels per day within the remaining few days of May appears highly unlikely.

The overwhelming 'No' odds in this Polymarket reflect a realistic assessment of the severe and entrenched disruptions affecting maritime trade in the Strait of Hormuz.
