Description

This market will resolve to "Yes" if a kinetic strike is conducted on, or forceful seizure of control is taken of, a commercial ship within the defined area on the specified date, between 12:00 AM and 11:59 PM GST (UTC+04:00). Otherwise, this market will resolve to "No". The defined area consists of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman. An incident occurring outside these three bodies of water will not qualify, including in the Arabian Sea, the Gulf of Aden, or the Red Sea. No attribution is required. A qualifying incident will count regardless of the identity of the party responsible, regardless of whether any state or group claims responsibility, and regardless of whether responsibility is denied, disputed, or never established. Attacks on military vessels will not be considered. Missile/drone strikes targeting a ship that are intercepted or otherwise do not directly impact the vessel will not be considered, regardless of damage through debris. Seize control refers to forcefully boarding and taking control of a commercial ship. Qualifying incidents include, but are not limited to, drone and missile strikes, aerial bombings, and kinetic actions carried out by operatives in person. Damaged caused by mines will not qualify. The primary resolution source for this market will be a consensus of credible reporting. The occurrence, location, and timing of a qualifying incident will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, location, or timing of a relevant incident, this market will remain open until the earlier of: i) the confirmation of the occurrence, location, and timing of the incident based on a consensus of information available from the resolution sources or ii) 3 full calendar days (GST) from the date of the first credibly reported evidence of the incident. If this period would extend past the end date, this market will remain open to allow for 3 full calendar days to pass. If, at the end of the third calendar day, conflicting reports remain as to the occurrence, location, or timing of the incident, the incident will be judged on the totality of information available from the resolution sources at that time. No single statement, denial, or presentation of evidence will govern where it is contradicted by the totality of information.

Frequently asked questions

On Polymarket, the dashboard for the Hormuz Strait shipping attacks tracks the implied probability of a successful attack occurring before the market’s close. You’ll find the current odds reflected in the price of YES and NO shares, along with a history of price movements. The dashboard also displays the 24-hour trading volume, currently at $122, and the total market volume, which is $184,901. This provides a clear view of how traders are assessing the likelihood of this event.

Currently, assessing whether prediction market odds align with analyst forecasts requires looking at the broader geopolitical landscape and expert opinions regarding security risks in the Hormuz Strait. Many analysts are closely monitoring regional tensions and potential disruptions to shipping lanes, but their predictions are often qualitative. This market offers a quantitative assessment, reflecting the collective judgment of traders on Polymarket. Discrepancies between the two may highlight differing perspectives on the probability of an attack.

On Polymarket, this market is priced through a continuous exchange where traders buy and sell shares representing their belief about whether shipping will be successfully targeted in the Hormuz Strait. The price of the YES share reflects the probability of an attack occurring, while the NO share represents the probability of it not happening. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price fluctuates based on supply and demand, driven by new information and shifts in trader sentiment, creating a real-time assessment of risk.

This market resolves around Sep 30, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will depend on whether a successful attack on shipping in the Hormuz Strait is confirmed by reputable news sources and governmental reports. The focus is on verified incidents impacting commercial or military vessels transiting the strait, and the outcome will be based on publicly available information at the time of resolution.

Several signals could significantly impact this market. Escalations in geopolitical tensions between Iran and other regional or global powers, particularly the United States, would likely increase the perceived risk. Specific threats made against shipping lanes, or actual incidents of harassment or minor attacks, could also drive up the price of YES shares. Conversely, diplomatic breakthroughs or de-escalatory measures could lower the price. Major naval exercises in the area, or changes in security protocols for shipping companies, are further events to watch.
