Strait of Hormuz Shipping Market Faces Extreme Headwinds Amid Renewed US-Iran Tensions

A Polymarket prediction market on the Strait of Hormuz traffic returning to normal by July 31 is pricing a 'No' outcome with high confidence, as recent escalations between the US and Iran have severely disrupted shipping, pushing transit calls far below the target threshold.

A prediction market on Polymarket, asking whether Strait of Hormuz traffic will return to a 7-day moving average of 60 transit calls by July 31, 2026, is currently reflecting a highly pessimistic outlook. With current prices at 0.0315 for “Yes” and 0.9685 for “No,” traders are assigning a mere 3.15% probability to a recovery in shipping activity, underscoring the severe geopolitical instability impacting the vital waterway.

The Market and Its Significance

The market’s resolution hinges on data from IMF Portwatch, specifically its 7-day moving average of transit calls for various ship types, including container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. The Strait of Hormuz is a critical global chokepoint, through which historically a significant portion of the world’s oil and gas transits. The market’s outcome therefore serves as a barometer for regional stability and global energy supply chain health.

Recent Developments: A Sharp Decline in Traffic

Recent events have dramatically curtailed shipping through the Strait. As of July 13, 2026, the Strait is facing extreme restrictions and closures due to renewed missile and drone attacks between the United States and Iran. Iran's Revolutionary Guards announced the closure of the strait, with the US contradicting this by stating the strait remains open but acknowledging significant disruption.

Prior to a conflict that began in February 2026, approximately 3,000 commercial vessels traversed the strait monthly, equating to about 130 daily crossings. An interim agreement in June briefly saw traffic recover to over 70 daily crossings. However, the latest hostilities have reversed this, with MarineTraffic reporting a 52% decline in vessel activity between July 10 and 12 compared to the previous week. On July 11, only 14 commercial vessels crossed the strait, and on July 13, fewer than five transited the waterway, according to satellite monitoring.

IMF Portwatch data from as early as April 7, 2026, already indicated a more than 95% collapse in daily vessel crossings compared to pre-war levels of 75 to 125 ships. Another prediction market referencing IMF Portwatch data for March 9-15, 2026, noted a 7-day moving average of just 5.857 transit calls. These figures are a stark contrast to the 60 transit calls required for the Polymarket to resolve “Yes.”

Market Odds Reflect Grim Reality

The current market odds of 0.0315 for “Yes” strongly suggest that traders do not anticipate a significant rebound in Strait of Hormuz traffic by the end of July. Given the ongoing military confrontations, Iran's stated intent to control the strait, and the observed drastic reduction in commercial shipping, a rapid return to a 7-day moving average of 60 transit calls appears highly improbable. The market is effectively pricing in the continuation of severe disruptions, with the probability of normalization before July 31 deemed negligible by participants.
