Strait of Hormuz Traffic Far From Normalcy as August 31 Deadline Nears, Polymarket Predicts 'No'

With just weeks remaining until the August 31 deadline, a Polymarket prediction market indicates an overwhelming skepticism that shipping traffic through the Strait of Hormuz will return to a 7-day moving average of 60 transit calls, reflecting persistent geopolitical tensions.

The critical Strait of Hormuz, a vital chokepoint for global energy supplies, remains significantly impacted by ongoing geopolitical tensions, with a Polymarket prediction market currently pricing an extremely low probability for a return to 'normal' traffic levels by August 31, 2026. This market, which has seen over $14 million in trading volume, will resolve to "Yes" only if the IMF Portwatch publishes a 7-day moving average of transit calls for the Strait of Hormuz equal to or above 60 before the deadline. Otherwise, it will resolve to "No".

Recent data paints a stark picture of disruption. As of August 9, 2026, the IMF Portwatch reported a 7-day moving average of daily transit calls for the Strait of Hormuz at a mere 4.57, a drastic reduction from the pre-crisis baseline of approximately 88 to 130 vessels per day. Other maritime intelligence firms corroborate this depressed activity; Kpler data cited by Reuters showed only six vessels crossing the Strait on August 10, with a 10-day average of around 11 vessels. Similarly, Windward data reported 16 total transits on August 11, and GuruFocus noted just five vessels crossing over the weekend of August 15-16.

These low figures are a direct consequence of escalating conflict between the United States and Iran, which began in late February 2026. Iran initially closed the strait to normal commercial traffic, and while a brief memorandum of understanding in June offered a glimmer of hope for reopening, it quickly broke down in early July following attacks on commercial vessels. The U.S. subsequently reimposed a naval blockade against vessels transiting to or from Iranian ports on July 14, further hindering commercial shipping. Marine insurers have estimated claims between $1.5 billion and $2 billion from approximately 70 casualties since February, highlighting the severe risks involved.

Diplomatic efforts to de-escalate the situation and fully reopen the waterway have largely stalled. Iran has reportedly set extensive conditions for a full reopening, including sanctions relief, compensation for damages from earlier conflict, an end to the U.S. naval blockade, and a region-wide ceasefire. U.S. President Donald Trump has indicated a preference for continued economic pressure as talks remain at an impasse.

The current market odds on Polymarket reflect this grim outlook, with the "Yes" outcome trading at 0.0115 (1.15% probability) and "No" at 0.9885 (98.85% probability). This indicates that traders overwhelmingly believe the 7-day moving average of 60 transit calls will not be met by August 31. Earlier in August, the probability for "Yes" was slightly higher, around 4%, suggesting a further decline in optimism as the deadline approaches and no significant breakthroughs occur.

The Strait of Hormuz is globally significant, handling nearly 20% of the world's daily oil supply and a substantial portion of global liquefied natural gas (LNG) exports. Its continued disruption has far-reaching implications for global energy markets, supply chains, and international trade, underscoring the importance of this prediction market's resolution.
