Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

The Strait of Hormuz is still a war-sensitive shipping chokepoint, and this contract only pays **Yes** if IMF Portwatch shows a 7-day average of at least 60 transit calls on any date before year-end. That makes the current **48% Yes** price close to a coin flip, but still below Polymarket’s reported **59%** and above Kalshi’s July read of **43% for 1 December**, suggesting the broader market sees some recovery potential without pricing a clean return to normal by the deadline.[1][6] Reuters reported in April that traffic was running at well below 10% of normal, with just seven ships in 24 hours versus about 140 ordinarily, underlining how far the flow has had to recover to clear the threshold.[5]

The historical analogue is the same pattern seen after sharp maritime disruptions: traffic can rebound quickly if security risks and enforcement constraints ease, but it often stalls below pre-crisis levels for weeks or months. Recent reporting has been mixed but directionally important: the New York Times said a June US-Iran preliminary agreement included measures to reopen the route, yet also warned of technical and military delays, including possible mine-clearing; later CNBC reporting in July said renewed fighting was again choking the corridor.[14][18] That mix supports a spread between prediction markets and any bullish analyst view, because the contract is tied to a specific, published traffic average rather than to diplomatic headlines alone.[1][14]

For traders, the main catalysts are any ceasefire enforcement, US-Iran maritime commitments, and the pace at which commercial carriers re-enter the lane, especially tankers and bulk carriers. The key dependency is not just whether ships are allowed through, but whether enough ships actually resume transit for the IMF Portwatch 7-day average to reach 60; Reuters and other trackers have repeatedly shown that even after brief reopenings, volumes have remained far below pre-war norms.[5][12][13] News on mine clearance, sanctions relief, port inspections, or renewed attacks would matter most because those factors directly affect whether the Portwatch series can print a qualifying average before 31 December 2026.[14][18]
