Strait of Hormuz Traffic Far from Normal as April Deadline Looms for Prediction Market

A Polymarket prediction market betting on the return to normal shipping traffic in the Strait of Hormuz by April 30, 2026, appears poised to resolve 'No,' with current data showing transit calls drastically below the required threshold amid ongoing geopolitical tensions.

The Polymarket prediction market asking whether Strait of Hormuz traffic will return to a 'normal' 7-day moving average of 60 transit calls by April 30, 2026, is currently trading with overwhelming odds against a 'Yes' resolution. With the deadline just days away, recent data from IMF Portwatch and analyses from maritime intelligence firms indicate that shipping activity remains severely hampered by the ongoing conflict in the region.

The market specifies that a 'Yes' outcome requires the IMF Portwatch 7-day moving average of transit calls for the Strait of Hormuz to reach or exceed 60 for any date between market creation and April 30, 2026. Transit calls include various ship types like container, dry bulk, and tankers. The current prices reflect a strong conviction that this will not occur, with 'No' trading at 0.9915 and 'Yes' at a mere 0.0085.

Shipping through the Strait of Hormuz, a critical chokepoint for approximately 20% of global petroleum and liquefied natural gas, has been in disarray since late February 2026 following US-Israeli strikes against Iran and subsequent Iranian retaliation. Before the conflict, the Strait saw a robust average of 84.1 ships per day between January 1 and February 27, 2026, with IMF PortWatch data showing 7-day moving averages in the range of 70-80, even reaching 100-110 in the two weeks prior to the effective closure.

However, the situation has dramatically deteriorated. From March 1 to April 12, the average daily transit calls plummeted to just 6-7 ships, with a slight, temporary increase to 8 following an April 8 ceasefire. Even after the ceasefire, from April 8 to April 19, daily vessel calls only modestly rose to 10.1, still an alarming 88% below pre-conflict levels. More recent data is even starker: on April 19, only three vessels transited the Strait, and by April 23, five vessels were recorded, all operating 'dark'—meaning with their Automatic Identification System (AIS) transponders switched off, signaling extreme risk perception. The latest IMF Portwatch 7-day moving average reported on April 12 was 6.57.

The ongoing disruption is multifaceted. Iran initially closed the strait, attacking and threatening commercial vessels and reportedly laying sea mines. It also imposed tolls and selective passage, often requiring coordination with its Islamic Revolutionary Guard Corps (IRGC). In response, the US implemented a counter-blockade on Iranian ports starting April 13, 2026, further complicating transit. Exacerbating the issue, soaring insurance costs and the perceived risk continue to deter major shipping companies from using the waterway, even during announced reopening windows. Some vessels have resorted to rerouting through Iranian territorial waters for selective passage, often with AIS transponders disabled.

Experts and industry observers are highly skeptical of a swift return to normalcy. Lloyd's List noted on April 23 that previous Polymarket odds (which were 60% for 'normal' by the end of May) seemed "optimistic, even under this generous definition of normality," emphasizing that the practical bar for the shipping industry is far higher than just raw numbers, requiring safe and predictable passage for major operators. The disruption is increasingly viewed as a "fundamental rewriting of global logistics network architecture" rather than a temporary anomaly. The severe decline in traffic has had cascading effects on global supply chains, impacting fertilizer prices and humanitarian aid delivery worldwide.

Given the current low transit numbers, the active dual blockades, and the persistent geopolitical instability, it is highly improbable that the Strait of Hormuz will see its 7-day moving average of transit calls reach 60 or above by the end of April. The market odds accurately reflect this dire outlook, signaling a near-certain 'No' resolution.
