Strait of Hormuz Traffic: Prediction Market Odds Reflect Ongoing Disruption Amid Geopolitical Tensions

A Polymarket prediction market on the Strait of Hormuz traffic returning to normal by August 31, 2026, is heavily favoring a 'No' resolution, reflecting the severe and ongoing disruption caused by the 2026 Iran War.

The Polymarket prediction market asking whether Strait of Hormuz traffic will return to normal by August 31, 2026, is currently trading at 0.9585 for 'No' and a mere 0.0415 for 'Yes'. This stark pricing indicates a strong market consensus that the vital waterway will not see its 7-day moving average of transit calls, as reported by IMF Portwatch, reach or exceed 60 vessels by the deadline. The market's skepticism is deeply rooted in the persistent geopolitical conflict and its severe impact on maritime trade.

The Strait of Hormuz, a critical chokepoint connecting the Persian Gulf to the open ocean, typically handles a significant portion of the world's seaborne oil and liquefied natural gas (LNG) trade. Before the escalation of the conflict in early 2026, the Strait saw an average of 88 to 140 ships transiting daily. However, since February 28, 2026, the waterway has been "largely blocked by Iran" following an air war with the United States and Israel. Iran's Revolutionary Guard Corps (IRGC) retaliated by issuing warnings, boarding merchant ships, and laying sea mines, effectively closing the strait to routine commercial shipping.

Recent data underscores the severity of the disruption. As of late July and early August 2026, daily transit calls have plummeted to a fraction of pre-crisis levels, with reports indicating traffic as low as 6 to 10 vessels per day. This contrasts sharply with the pre-war average of 130 to 140 ships and the market's 'Yes' threshold of a 7-day moving average of 60 transit calls. IMF Portwatch, the official resolution source for this market, itself acknowledges "Trade disruptions in the Strait of Hormuz due to attacks on commercial ships" since February 28, 2026, and reports that daily vessel crossings, which averaged between 75 and 125 ships before the war, "have collapsed by more than 95%". Crude oil and LNG flows, in particular, remain "near zero".

Efforts to de-escalate the situation and reopen the Strait have largely failed. A brief reopening period under a June US-Iran agreement broke down in early July following renewed attacks on commercial vessels. Iran has since issued stringent demands for a full reopening, including the US ending the war and blockade, releasing Iran's frozen assets, and agreeing to a region-wide ceasefire. These demands have been described by experts as "shooting for the moon," making a swift resolution unlikely.

The ongoing closure has forced a significant rerouting of vessels around the Cape of Good Hope, adding 10 to 20 days to transit times and dramatically increasing freight rates. This has contributed to a global fuel crisis and widespread supply chain disruptions. While US Energy Secretary Chris Wright recently claimed a 7-day average of almost 9 million barrels per day of oil leaving the Strait, independent analysts like Bloomberg's Javier Blas assess the actual volume to be much lower, around 4-6 million barrels per day, and critically, this market resolves on transit calls, not cargo volume.

Given the current daily transit figures are still in the single digits, and previous attempts at recovery (which peaked in the forties and fifties in June before unwinding in mid-July) fell short of the 60-vessel threshold, the market's confidence in a 'No' resolution appears well-founded. Unless a dramatic and unforeseen geopolitical breakthrough occurs in the coming weeks, it is highly improbable that the Strait of Hormuz will see traffic return to a 'normal' level of 60 transit calls by August 31, 2026.
