Strait of Hormuz Traffic Far From Normal as May Deadline Looms, Prediction Market Favors 'No'

With just days remaining until the May 31st deadline, a Polymarket prediction market indicates a strong consensus that shipping traffic through the Strait of Hormuz will not return to normal levels, reflecting ongoing geopolitical tensions and severe disruptions to global maritime trade.

A high-stakes prediction market on Polymarket, with over $22 million in trading volume, is poised to resolve with a resounding 'No' as shipping traffic through the Strait of Hormuz remains significantly depressed, far below the threshold required for a 'Yes' outcome by May 31, 2026. The market question, "Strait of Hormuz traffic returns to normal by end of May?", hinges on the IMF Portwatch publishing a 7-day moving average of transit calls equal to or above 60. Current data and geopolitical realities strongly suggest this benchmark will not be met.

The Market and Its Significance

The Strait of Hormuz, a critical chokepoint for global energy and trade, typically sees a high volume of maritime traffic, including oil tankers, container ships, and dry bulk carriers. The market's resolution is directly tied to the 7-day moving average of transit calls as reported by IMF Portwatch. A return to a 7-day average of 60 vessels would signify a significant recovery from the severe disruptions that have plagued the region in recent months. The market's substantial trading volume of $22,347,637 underscores the global interest and economic implications of the Strait's operational status.

Recent Developments Point to Continued Disruption

Since late February and early March 2026, the Strait of Hormuz has been described as "effectively closed" or under "significant restriction" to commercial shipping, primarily due to an escalating conflict involving the United States, Israel, and Iran. Iran has reportedly established a "controlled maritime zone," imposing tolls and requiring authorization for vessels to transit, a move rejected by the U.S. and China as a violation of international maritime law.

Major shipping lines, including Maersk, MSC, CMA CGM, and Hapag-Lloyd, have largely suspended transits through the Strait, citing heightened attack risks and the withdrawal of insurance coverage. According to Kpler, traffic through Hormuz ran at approximately 5% of its pre-war average across April. Prior to the conflict, the Strait typically saw 125 to 140 vessels daily.

Recent daily transit figures reported by various sources in May 2026 consistently fall far short of the 'normal' threshold. For instance, Windward reported 19 vessels on May 20 and 12 vessels on May 21. ShipFinder noted 13 total transits on May 22, with daily movements generally reduced to a mere 10 to 16 vessels, according to ChemAnalyst. Even claims by the Islamic Revolutionary Guard Corps Navy of 26-35 vessels transiting after obtaining Iranian 'permission' are significantly below the required average.

Crucially, the resolution source, IMF Portwatch, last updated on May 17, 2026, reported a "Daily Transit Calls (7-Day Moving Avg)" of a mere 6.29, with daily transit calls at 2.00. The next weekly update from IMF Portwatch is scheduled for May 27, 2026. Given the current low numbers, it is highly improbable that the 7-day moving average will surge to 60 by the May 31 deadline.

Adding to the complexity, the ongoing Red Sea crisis, marked by Houthi attacks, continues to reroute global shipping, though some vessels have reportedly returned to the Red Sea due to the severe disruptions in Hormuz.

Market Odds Reflect Grim Outlook

The current market prices reflect a strong conviction among traders that the 'Yes' outcome is unlikely. The price for 'Yes' stands at 0.1565 (15.65%), while 'No' is trading at 0.8435 (84.35%). This overwhelming lean towards 'No' aligns with the factual information available, indicating that market participants do not anticipate a significant recovery in Strait of Hormuz traffic by the end of May. The persistent geopolitical instability, military actions, and the reluctance of major shipping companies to re-enter the high-risk area collectively contribute to this pessimistic outlook for a return to normalcy. A multinational military mission announced on May 12, 2026, aims to support freedom of navigation, but its operations are contingent on a "permissive environment", which is currently absent.

As the deadline approaches, the data strongly suggests that the Strait of Hormuz will remain a highly constrained and volatile maritime corridor, with traffic levels far from what would be considered normal. The market's current odds accurately reflect this challenging reality.
