Will Strait of Hormuz Shipping Traffic Normalize by Dec 31,

What is happening now

Traders on Polymarket are betting that the Strait of Hormuz will see “normal” shipping volumes – defined as a 7‑day moving average of at least 60 ship arrivals – before the end of 2026. The market currently prices the “Yes” outcome at 75.5 ¢ (≈75.5 % implied probability) and the “No” outcome at 24.5 ¢. In the past month the contract has absorbed roughly $3.8 million of total volume, with $306 k traded in the last 24 hours and about $268 k of liquidity available for new orders.

Recent geopolitical developments have reinforced the bullish view. A series of missile attacks on commercial vessels in the strait (including the CMA CGM incident reported in late June) have been followed by diplomatic signals that the United States and Iran are maintaining a “de‑escalation” channel, reducing the risk of a broader naval confrontation. Meanwhile, IMF Portwatch data shows the 7‑day moving average of arrivals has been hovering in the mid‑50s since early June, just a few calls short of the 60‑ship threshold.

How the market is structured

This is a binary market: only two outcomes exist – “Yes” (traffic normalizes to ≥60 arrivals) or “No” (it does not). The contract resolves the moment IMF Portwatch publishes a qualifying 7‑day average at any point before 31 December 2026, or automatically at the end of the period if the threshold is never reached. The leading outcome is “Yes” at 75.5 %.

Path to the leading outcome

• IMF Portwatch data crossing 60. A single published 7‑day moving average of 60 or higher will settle the market in favor of “Yes”. The current trend (mid‑50s) suggests a modest uptick in arrivals could trigger the threshold within weeks.
• Reduced security incidents. Any credible statement that missile threats have been mitigated – for example, a verified cease‑fire or a successful diplomatic “hot‑line” agreement – would likely encourage ship owners to resume regular schedules, pushing the metric upward.
• Operational reports from major carriers. Press releases from firms such as Maersk, MSC or CMA CGM confirming restored regular calls through the strait would act as leading indicators that the IMF data will soon reflect normal traffic.

What could change the pricing

• Escalation of hostilities. A new missile strike, naval encounter, or a formal escalation in U.S.–Iran tensions would likely depress ship movements, pulling the 7‑day average back below 60 and shifting the market toward “No”.
• Data revisions or anomalies. IMF Portwatch occasionally revises past figures. A downward revision of recent weeks could erase a previously qualifying average, reopening the “No” side.
• Alternative data sources. If reputable maritime analytics (e.g., MarineTraffic, IHS Markit) publish a divergent picture showing sustained low traffic, traders may doubt the IMF threshold’s relevance and reprice toward “No”.
• Regulatory or insurance constraints. New sanctions, insurance black‑lists, or mandatory rerouting orders could keep carriers away from the strait even if the security environment improves, limiting the arrival count.

Editorial read

The Polymarket contract “Strait of Hormuz traffic returns to normal by December 31?” is heavily weighted toward a positive outcome (75.5 % implied probability). This reflects a market consensus that the recent spike in missile activity is a short‑term flare‑up rather than a lasting disruption, and that ship traffic is poised to rebound before year‑end. The market’s $3.8 M volume and $268 k liquidity indicate strong participation, while the 24‑hour flow of $306 k shows continued interest as the year progresses.

Resolution hinges on a single, objective data point from IMF Portwatch – a 7‑day moving average of ≥60 arrivals. Because the metric is transparent and published weekly, the market can react quickly to any shift in the underlying data. Traders should watch for (a) a confirmed crossing of the 60‑ship threshold in the next IMF release, (b) credible diplomatic de‑escalation signals, and (c) any fresh security incidents that could reverse the upward trend.

If the strait’s traffic does normalize as the market expects, “Yes” holders will collect $1 per share at resolution. Conversely, a resurgence of conflict or a data revision that keeps the average below 60 would vindicate the 24.5 % “No” price, rewarding those who backed the downside.
