Strait of Hormuz Traffic: Prediction Market Reflects Bleak Outlook for Recovery Amid Ongoing Conflict

A Polymarket prediction market indicates extremely low confidence that daily shipping traffic through the Strait of Hormuz will return to a 7-day moving average of 60 transit calls by September 30, 2026, reflecting the severe and persistent disruptions caused by the ongoing US-Israel-Iran conflict.

The critical Strait of Hormuz, a vital chokepoint for global energy and trade, remains heavily disrupted, with a Polymarket prediction market currently pricing a mere 6.5% chance that its 7-day moving average of transit calls will reach 60 or more by September 30, 2026. This market, with a significant trading volume of over $4.6 million, highlights widespread skepticism about a swift return to normalcy in one of the world's most geopolitically sensitive waterways.

The market's resolution hinges on data from IMF Portwatch, which tracks daily transit calls for various ship types including container, dry bulk, roll-on/roll-off, general cargo, and tanker vessels. A "Yes" resolution requires the 7-day moving average to hit or exceed 60 transit calls at any point between market creation and the September 30 deadline.

Escalating Conflict and Shipping Collapse

The severe downturn in Strait of Hormuz traffic stems directly from the ongoing "2026 US-Israel-Iran war," which began on February 28, 2026, with US and Israeli air strikes against Iran. In retaliation, Iran's Revolutionary Guard Corps (IRGC) swiftly moved to restrict passage through the Strait, issuing warnings, boarding merchant ships, and reportedly laying sea mines.

Pre-conflict, the Strait saw an average of 100 to 153 commercial vessels transiting daily. Since early March 2026, however, traffic has plummeted dramatically, with some reports indicating daily transit numbers for non-Iranian ships dropping to single digits. As recently as August 19, 2026, only six commodity vessels crossed the strait on Tuesday, a decrease from nine the previous day and below the 10-day daily average of 11. Another report for the week of August 3-9 noted 45 transits, down from 63 the prior week, and significantly lower than the 138 daily transits before the conflict. Overall, by August 13, 2026, only 3,371 vessels had crossed the strait since February 28, representing roughly 20% of pre-war traffic.

Complex and Dangerous Operating Environment

Iran has asserted unprecedented administrative control over the waterway, reportedly establishing a formal registration and pre-approval system, and even charging transit fees up to $2 million per tanker. The traditional central route has been declared a danger zone, with Iran mandating a route along its southern coast. Further complicating matters, the U.S. reimposed a blockade against vessels transiting to or from Iranian ports on July 14, 2026.

These actions have created an extremely hazardous environment. Maritime security incidents, including projectile strikes and suspected drone attacks, continue to affect commercial shipping. Major shipping companies like Maersk and MSC have suspended transits, and war risk insurance, which was withdrawn on March 5, 2026, has seen premiums surge from 0.25% to 7.5-10% of a vessel's total value for a typical very large crude carrier. Many vessels are resorting to "dark navigation," disabling AIS transponders to avoid detection, which significantly increases collision risks and can void insurance. Even the resolution source, IMF Portwatch, acknowledges "reports of GPS jamming, AIS spoofing, and vessels going dark" affecting data reliability.

Market Odds Reflect Reality

The current market odds, with "No" trading at 0.935, strongly suggest that traders do not anticipate a significant recovery in traffic by the September 30 deadline. Given the entrenched geopolitical conflict, the ongoing blockades, the severe security risks, and the substantial financial and logistical hurdles for shipping companies, a return to a 7-day moving average of 60 transit calls appears highly improbable in the short term. The situation remains volatile, with no clear path to de-escalation that would enable a rapid restoration of normal shipping volumes through this critical global artery.
