Strait of Hormuz: High Stakes and Low Odds for Return to Normal by June End

A Polymarket prediction market on Strait of Hormuz traffic returning to a 7-day average of 60 transit calls by June 30, 2026, currently heavily favors 'No,' reflecting ongoing geopolitical instability, physical impediments, and a recent Iranian reclosure announcement.

The critical Strait of Hormuz, a vital chokepoint for global maritime trade, remains embroiled in geopolitical tensions, making the prospect of its shipping traffic returning to normal levels by the end of June highly unlikely. A Polymarket prediction market, which resolves to “Yes” if the IMF Portwatch 7-day moving average of transit calls reaches or exceeds 60 by June 30, 2026, currently shows overwhelming odds against this outcome, with “No” trading at 0.925 (92.5% implied probability) against “Yes” at 0.075.

Market at a Glance

This prediction market monitors the 7-day moving average of transit calls for container, dry bulk, roll-on/roll-off, general cargo, and tanker ships through the Strait of Hormuz, as reported by IMF Portwatch. The threshold for resolution to “Yes” is 60 transit calls. The market's significant trading volume of over $30 million underscores the global economic importance of this waterway, through which historically 20-30% of global oil consumption and a substantial portion of liquefied natural gas (LNG) passed daily. Prior to the recent conflict, the Strait typically saw between 75 and 138 vessel transits per day.

Recent Developments and Impact

Shipping through the Strait of Hormuz has been severely disrupted since February 28, 2026, following a US-Israel war against Iran, leading to a collapse in traffic by over 90% at one point. A brief respite occurred on June 18, 2026, after a memorandum of understanding (MoU) between the US and Iran was signed, leading to reports of 25 commercial vessels crossing that day – the highest single-day count since mid-April and more than five times the average daily level recorded in early June.

However, this tentative reopening was short-lived. Iran announced on June 20-21, 2026, that it was reclosing the Strait, citing alleged violations of the MoU by the United States and Israel concerning the conflict in Lebanon. While U.S. Central Command (CENTCOM) maintained that the Strait remained open, reporting 55 merchant ships transiting on June 20, other sources indicated an "unprecedented and complete paralysis of outbound commercial maritime traffic" with zero transits over the preceding five days as of June 20.

Adding to the complexities, the main shipping route through the center of the Strait is reportedly obstructed by approximately 80 mines, requiring a significant de-mining effort that could take up to six months for normal operations to resume. Furthermore, Iran has asserted new control measures, requiring vessels to seek permission from the Persian Gulf Strait Authority (PGSA) and adhere to specific routes and safety requirements, with plans to impose transit fees. Shipping experts have noted that such fees could make the longer route around the Cape of Good Hope a more economically viable alternative for some carriers.

Analysis of Market Odds

The current IMF Portwatch data as of June 14, 2026, shows the 7-day moving average of daily transit calls at a mere 2.57. To reach the market's "Yes" threshold of 60 by June 30, the average would need an extraordinary and sustained surge in traffic over the next few days. Given the latest developments—Iran's reclosure announcement, the physical impediment of mines, and the established rerouting of major shipping lines around the Cape of Good Hope—a rapid return to normal appears highly improbable. Industry experts widely agree that a full restoration of confidence and traffic will take months, not weeks. The overwhelming odds favoring "No" in the Polymarket reflect this stark reality, indicating that the market participants do not foresee a quick normalization of traffic in the Strait of Hormuz within the stipulated timeframe.
