Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

The Strait of Hormuz has not yet shown a sustained return to the market’s definition of “normal”, which is a seven-day moving average of at least 60 transit calls in IMF PortWatch data. Polymarket is pricing the contract at about **56% YES**, while Kalshi-linked reporting has shown a slightly higher or lower band depending on the date, generally clustering in the **high-40s to low-60s**, so the cross-platform split is modest rather than dramatic.[2][4][8][11]

For context, this is a classic *recovery-from-disruption* trade: comparable shipping markets often over-discount the speed of a rebound when geopolitical shocks ease, then repricing follows whether the operational bottleneck is security, insurance, or backlog clearance. Reuters reported in April that Hormuz traffic remained at well below 10% of normal volumes despite a ceasefire, and later coverage said traders on Kalshi were still assigning sub-50% odds to a normal flow by mid-2027, which shows how slowly confidence can recover after a major maritime disruption.[16][11] Octagon AI’s market read, by contrast, puts the year-end normalisation case slightly above even money and notes no clear mispricing, but that sits against a much more cautious Kalshi tape in recent coverage.[1][11]

The main catalysts are any durable Iran-related ceasefire or security agreement, plus whether shipping insurers and operators deem the corridor safe enough to restore routine schedules. Reuters and other recent reports have pointed to renewed regional tension, while analysts quoted in coverage have said traffic will only normalise once there is a stable security environment, predictable rules of engagement, and no fresh vessel incidents.[20][13] Traders should also watch weekly IMF PortWatch prints closely: the contract resolves as soon as a published seven-day average reaches the threshold, so a brief burst of traffic, backlog clearance, or a reporting lag could move the market sharply before year-end.[18][1]
