Strait of Hormuz Traffic: Market Bets Against Return to 'Normal' Amid Ongoing Tensions

A Polymarket prediction market on the Strait of Hormuz traffic returning to a 7-day moving average of 60 transit calls by December 31, 2026, currently shows a strong lean towards 'No' (62.5%). This reflects deep skepticism amidst ongoing geopolitical conflict and significantly depressed shipping vol

The Strait of Hormuz, a critical maritime chokepoint accounting for approximately 20-25% of the world's seaborne oil and liquefied natural gas (LNG) trade, remains a focal point of global geopolitical and economic concern. A Polymarket prediction market, with a substantial trading volume of over $9.5 million, is gauging whether the 7-day moving average of transit calls through the Strait will reach or exceed 60 by December 31, 2026. Current market odds heavily favor a 'No' resolution at 62.5%, suggesting traders anticipate continued disruption.

This market's resolution hinges on data from IMF Portwatch, which tracks various ship types including container, dry bulk, roll-on/roll-off, general cargo, and tanker vessels. The target of 60 transit calls represents a return to a significant level of activity, though still below the pre-conflict baseline of 100 to 138 daily arrivals.

Escalating Tensions and Collapsed Traffic

The Strait of Hormuz has been severely impacted by an ongoing conflict involving the United States, Israel, and Iran, which commenced on February 28, 2026. This geopolitical instability led to a dramatic collapse in shipping traffic, with initial reports indicating a near-total halt and a subsequent decline of over 90% in commercial vessel transits. The International Maritime Organization (IMO) reported in April that up to 20,000 seafarers and 2,000 vessels were stranded in the Persian Gulf.

As of mid-August 2026, the 7-day moving average of daily transit calls, according to IMF PortWatch data, stood at a mere 3.57 on August 16. While some reports from late August indicate a recent surge in traffic—with nearly 200 ships navigating the strait in one week, a 400% increase from two weeks prior—this still only brings activity to approximately 20% of pre-war levels. This figure remains significantly below the 60-call threshold for the market to resolve 'Yes'. For context, a previous Polymarket question with the same threshold for July 15, 2026, resolved 'No', with the 7-day average at that time around 5 ships per day.

Complex Geopolitical Landscape

Several factors contribute to the depressed traffic. Iran's Revolutionary Guard Corps (IRGC) has issued warnings, boarded and attacked merchant ships, and deployed sea mines. Iran has also asserted its right to control the strait, proposing new regulations and transit fees, and even issuing a blacklist of 45 vessels it alleges violated its rules. In response, the U.S. has conducted aerial campaigns and blockaded Iranian ports. The U.S. has also been reportedly escorting oil tankers through a U.S.-backed Omani route since May 2026.

Despite an announced framework on August 25, 2026, between Iran and Oman for restoring safe navigation, including a temporary shipping corridor and joint mine-clearing operations, Iran has continued its assertive actions.

Market Implies Continued Uncertainty

The current market odds of 62.5% for 'No' reflect a strong belief among traders that the complex interplay of geopolitical tensions, ongoing security risks, and commercial hesitancy will prevent a sustained return to 60 daily transit calls by the year's end. Commercial operators and insurers are demanding definitive peace agreements and robust security guarantees before committing valuable vessels and crews, further delaying any normalization. Additionally, many ships are reportedly operating with their Automatic Identification System (AIS) transponders switched off, a tactic known as "going dark," which could lead to an undercount of actual physical traffic in the IMF Portwatch data.

While the Red Sea crisis, driven by Houthi attacks, has also caused significant global shipping disruptions, the issues in the Strait of Hormuz are distinct and directly related to the conflict in the Persian Gulf. The market's current sentiment underscores the significant challenges in de-escalating the situation and restoring confidence in one of the world's most vital energy arteries.
