Strait of Hormuz Traffic Market Plummets Amid Renewed US-Iran Tensions, 'Normal' Resolution Highly Unlikely

A Polymarket prediction market betting on the return of Strait of Hormuz shipping traffic to a 7-day moving average of 60 by July 31 is trading at an extremely low 'Yes' probability, reflecting severe disruptions from ongoing US-Iran hostilities.

The critical Strait of Hormuz, a vital artery for global energy trade, remains ensnared in severe geopolitical turmoil, casting a long shadow over a Polymarket prediction market focused on its shipping traffic. The market, titled "Strait of Hormuz traffic returns to normal by July 31?", is set to resolve to "Yes" if IMF Portwatch publishes a 7-day moving average of transit calls equal to or above 60 for any date between market creation and July 31, 2026. With the current "Yes" price hovering at a mere 0.0105, market participants are signaling an overwhelming consensus that a return to such traffic levels is highly improbable.

This Polymarket is more than just a speculative bet; it serves as a real-time barometer for the stability of a chokepoint through which approximately 20% of the world's crude oil and significant volumes of liquefied natural gas (LNG) pass. The resolution relies specifically on data from IMF Portwatch, an open platform tracking maritime trade flows using satellite-based data and the Automatic Identification System (AIS).

The dramatic pessimism reflected in the market odds stems directly from the escalating conflict between the United States and Iran, which commenced on February 28, 2026. Prior to the conflict, daily vessel transits through the Strait of Hormuz typically ranged between 75 and 125 ships. However, following the onset of hostilities, traffic plummeted, averaging as low as 10-12 crossings per day between March and May 2026.

A brief reprieve was observed after a "memorandum of understanding" ceasefire deal was signed on June 18, 2026. This led to a temporary recovery, with transits returning to around 40-45 vessels per day, and an average of 60 through the days immediately following the agreement. This momentary surge, reaching the market's target threshold, proved short-lived.

Recent developments in July 2026 indicate a sharp deterioration in maritime activity. Renewed US-Iran hostilities, including Iranian declarations of minefields, warnings against unauthorized transit, and the interception of oil tankers, coupled with a renewed U.S. naval blockade, have plunged traffic back to severely depressed levels. Clarksons Research reported an average of just 12 crossings per day for the five days leading up to July 20. Similarly, the latest data available from IMF Portwatch for July 13-19 showed an average of only 10 transits per day. ShipFinder recorded a mere 15 vessels on July 22. These figures are a stark contrast to the 60-vessel 7-day moving average required for a "Yes" resolution.

IMF Portwatch itself notes "Reduced traffic since February 28, 2026 — Ongoing" for the Strait of Hormuz, and warns users about potential GPS jamming, AIS spoofing, and vessels going dark due to the conflict. The current market odds of 0.9895 for "No" underscore the deep skepticism among traders that any significant recovery to pre-conflict or even post-MOU levels will occur by the July 31 deadline, given the persistent and escalating geopolitical instability in the region. The extreme challenges facing maritime commerce in this vital waterway suggest that the market's strong lean towards a "No" outcome is well-founded.
