Strait of Hormuz Traffic: Prediction Market Odds Reflect Deepening Crisis as July 31 Deadline Nears

A Polymarket prediction market betting on the return of normal shipping traffic through the Strait of Hormuz by July 31, 2026, shows overwhelming odds against a recovery, reflecting the severe ongoing disruption in the critical waterway.

The Strait of Hormuz, a vital chokepoint for global energy and trade, remains in a state of severe disruption, with a Polymarket prediction market indicating an exceptionally low probability of traffic returning to normal levels by the July 31 deadline. The market, which resolves to 'Yes' if the IMF Portwatch's 7-day moving average of transit calls reaches or exceeds 60 by the end of the month, currently prices 'Yes' at a mere $0.016, while 'No' trades at a dominant $0.984.

This dire outlook is a direct consequence of the ongoing geopolitical conflict in the region. Since February 28, 2026, the Strait of Hormuz has faced extreme restrictions, largely due to an escalating conflict involving the United States, Israel, and Iran. Iran's Revolutionary Guard Corps (IRGC) has actively impeded passage, issuing warnings, boarding merchant ships, and reportedly laying sea mines. The United States also implemented a naval blockade of Iranian ports from April to May 2026.

These actions have had a catastrophic impact on maritime activity. Reports from UNCTAD indicated a near halt to ship transits by March 10, 2026. By early May, traffic was estimated to be running at approximately 5% of its pre-war average, with over 1,550 vessels stranded and 22,500 mariners trapped. More recently, on July 12, 2026, only 11 ships traversed the Strait, the lowest since mid-June following further US and Iranian retaliatory strikes. As of July 19, 2026, only 13 vessels were recorded.

Data from IMF Portwatch, the designated resolution source for this market, corroborates the severe downturn. As of July 12, 2026, the Daily Transit Calls (7-Day Moving Average) for the Strait of Hormuz stood at a mere 16.43, with daily calls at 10.00. This is a stark contrast to the pre-disruption environment, where over 30,000 vessels passed through the Strait annually, and daily oil transport volumes surpassed 20 million barrels in 2022. The current figures are far below the 60 calls threshold required for a 'Yes' resolution, underscoring the depth of the crisis.

Geopolitical tensions continue to fuel the disruption. President Trump's declaration of an 'Iran Blockade' demanding a 20% transit fee and Iran's assertion of 'full control' further highlight the breakdown of established international norms for freedom of navigation. The International Maritime Organization has advised all ships to avoid Hormuz transits until safety can be assured, and war risk premiums have surged by 36.7 times the normal rate. Concerns over GPS jamming and AIS spoofing also contribute to the hazardous environment.

The current market odds of 0.016 for 'Yes' reflect a near-unanimous consensus among traders that a return to normal traffic, defined by a 7-day moving average of 60 transit calls, is highly improbable within the next week. This aligns with recent analyses from other prediction markets, where odds for normal traffic by year-end 2026 have also tumbled following continued US airstrikes targeting Iranian forces. With the current transit numbers hovering in the low teens, a dramatic and unforeseen de-escalation, coupled with a rapid recommencement of commercial shipping, would be required to meet the market's 'Yes' condition by July 31 – an outcome that appears exceedingly unlikely given the prevailing security landscape.
