Intro

This market tracks whether there will be more than 20 transit calls through the Strait of Hormuz between September 7, 2026 and September 13, 2026. Currently, the leading outcome – that there *will* be more than 20 transit calls – is trading at 99.0% on Kalshi. Resolution will be based on the number of transit calls reported by the IMF PortWatch during that period. Market participants should closely watch for any developments regarding regional maritime security leading up to the resolution date of September 15, 2026, as this will directly impact the final count of vessel transits.

Kalshi

Each market resolves to Yes if the total number of transit calls through the Strait of Hormuz, as reported by IMF PortWatch, exceeds a specified threshold between September 7 and September 13, 2026. The total is the sum of daily counts over this week. All markets will resolve no earlier than Tuesday at 9 AM following the end of the period, once complete data is available.

Currently, prediction market odds often reflect a different perspective than traditional polls and analyst forecasts regarding geopolitical events like those impacting the Strait of Hormuz. While polls capture stated opinions, this market aggregates informed speculation through financial incentives. Discrepancies can arise from differing levels of expertise, access to information, and the incentive to be accurate when money is at stake. It’s common to see this market adjust rapidly to emerging news, potentially offering a more dynamic assessment than static polling data.

On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing potential outcomes for vessel traffic, and the price of each contract reflects the market's collective belief about the probability of that outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price movements are driven by supply and demand – if more traders believe an outcome is likely, they will bid up the price of contracts representing that outcome, and vice versa. This creates a dynamic pricing mechanism that continuously updates as new information becomes available.

This market resolves around Sep 15, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will be based on publicly available data concerning the average daily number of vessels passing through the Strait of Hormuz during the specified period (September 7th to September 13th). The exact methodology for determining the outcome will be based on established and verifiable data sources, ensuring a transparent and objective resolution process.

Several factors could significantly impact this market. Escalations in geopolitical tensions in the region, such as increased military presence or direct confrontations, would likely cause substantial shifts. Unexpected disruptions to oil production or shipping routes, perhaps due to attacks or accidents, could also move the market. Major announcements from key international actors regarding security arrangements or diplomatic efforts related to the Strait of Hormuz would be closely watched by traders. Any significant changes in global oil prices could also influence perceptions of risk and impact trading activity in this market.
