This event identifies which specific day during July 20-26, 2026 experiences the highest maritime traffic through the Strait of Hormuz. It helps forecast when peak shipping activity is most likely to occur during the week.
Resolution is determined by comparing daily transit call counts through the Strait of Hormuz as reported by IMF PortWatch for each day from July 20 through July 26, 2026, and identifying which date has the highest count. Each calendar day represents a separate market outcome that resolves to Yes if that day records the maximum traffic. If multiple days tie for the highest count, each tied day's market resolves to 1/N, where N equals the number of days sharing the peak value. Data must be complete before resolution, which occurs no earlier than Tuesday at 9 AM following the end of the measurement period.
Prediction markets and traditional polling serve different purposes in forecasting. While polls capture snapshot opinions from surveyed populations, this market aggregates real-money bets from traders who face direct financial consequences for inaccuracy. Prediction market participants often incorporate specialized knowledge about maritime logistics, geopolitical tensions, and shipping patterns that general polls may not capture. The odds here reflect forward-looking expectations rather than current sentiment, making them particularly valuable for events with clear, verifiable outcomes. Traders continuously update their positions as new shipping data and regional developments emerge, creating a dynamic probability estimate.
On Kalshi, this market is priced through a continuous order-book mechanism where traders buy and sell shares corresponding to each possible peak traffic day. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each share represents a claim on a specific outcome, and the current market price reflects the collective assessment of that day's likelihood. Traders profit by correctly predicting which day will see the highest Strait of Hormuz traffic, with payouts determined by the verified outcome. The platform's matching engine ensures transparent price discovery, allowing participants to enter or exit positions at any time before resolution.
This market resolves around Aug 4, 2026, once the peak traffic day for the specified week can be verified from credible public sources. The outcome is determined by identifying which single day recorded the highest number of vessel transits through the Strait of Hormuz during the resolution window. Traders' positions settle based on whether their chosen day matches the verified peak, with payouts distributed accordingly. Resolution depends on reliable maritime traffic data becoming publicly available and confirmed through established reporting channels.
Several factors could shift odds in this market significantly. Geopolitical tensions in the Middle East, sanctions announcements, or military incidents could alter shipping patterns and vessel routing decisions. Energy market volatility, OPEC production changes, and global oil price swings influence tanker traffic through the strait. Weather disruptions, port congestion, or maritime accidents may redirect vessels or concentrate traffic on specific days. Real-time shipping data releases, satellite imagery, and official maritime authority reports provide concrete signals that traders monitor closely. Economic indicators affecting global energy demand and regional stability assessments also drive probability adjustments as the resolution week approaches.
