This market defines a ceasefire breach through very specific technical parameters rather than formal diplomatic announcements. It restricts qualifying actions to direct airstrikes or surface-to-surface missile impacts on terrestrial territory, while explicitly excluding intercepted munitions, debris, ground incursions, artillery, and short-range drones. Determining whether an impact was caused by an unintercepted warhead versus falling interceptor debris during a complex strike relies heavily on consensus reporting and official claims. Resolution depends on subjective synthesis of credible media and military statements from both sides rather than a single authoritative dataset, giving the decider wide latitude when conflicting claims arise.

Market explained before close

This market measures whether a ceasefire between Israel and Iran remains in effect through October 21 at 11:59 PM IRST, specifically defined by the absence of directly impacting airstrikes or surface-to-surface missile strikes between the two nations.

How it resolves

The market resolves to Yes if a ceasefire remains in effect between Israel and Iran through October 21 at 11:59 PM IRST. The market resolves to No if either Israel or Iran conducts a qualifying military action—defined as an airstrike or surface-to-surface missile strike directly impacting the other country's terrestrial territory or internal waters—before the deadline. Intercepted munitions, falling debris, ground incursions, naval/artillery fire, cyber operations, minor strikes (like FPV drones or ATGMs), and unexecuted threats do not count as qualifying actions. Outcomes are determined by a consensus of official information from the governments and militaries of Israel and Iran along with credible reporting. If reports conflict, resolution may be delayed by up to 3 full calendar days.

Resolution rules at close

This market will resolve to "Yes" if a state of ceasefire remains in effect between Israel and Iran through the listed date, 11:59 PM Iran Standard Time (IRST). Otherwise this market will resolve to “No”. A state of ceasefire will be considered to no longer be in effect between Israel and Iran if either Israel or Iran takes a qualifying military action against the other country between market creation and the listed date, 11:59 PM IRST. A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by Israel or Iran, that directly impacts the other country. An air strike includes bombs, air-to-surface missiles, and air-launched drones. A surface-to-surface missile strike includes one-way attack drones and surface-to-surface missiles such as cruise or ballistic missiles. The following actions do not constitute a qualifying military action: Munitions destroyed or intercepted before impact; Surface-to-air missile strikes; Small-arms fire; Ground incursions; Cyber operations; Naval gunfire and artillery fire; Howitzers, artillery pieces, mortars, and rocket artillery (e.g. MLRS systems); Minor surface-to-surface strikes, including short range loitering munitions, FPV drones, and ATGM strikes; Any threat, authorization, or announcement of force that has not been executed. Any munition that is intercepted or destroyed before impact does not constitute a qualifying military action. Debris, fragments, or any wreckage from intercepted munitions that land on Israel or Iran do not constitute a military action regardless of any damage incurred. A military action will be considered to impact Israel or Iran if it directly impacts the terrestrial territory of Israel or Iran, including any internal waters. Maritime territory and airspace are not encompassed. Where territorial borders are disputed, all territory claimed by and under the de facto control of the relevant state as of market creation will qualify. The occurrence, attribution, and timing of a qualifying military action will be primarily determined based on a consensus of information available from the resolution sources. Where multiple sources conflict regarding the occurrence, attribution, or timing of a relevant military action, this market will remain open until the earlier of: i) the confirmation of the occurrence, attribution, and timing of the action based on a consensus of information available from the resolution sources or ii) 3 full calendar days (IRST) from the date of the first credibly reported evidence of the action. 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, attribution, or timing of the action, this market will resolve based 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. The resolution sources for this market will be official information from the governments and militaries of Israel and Iran and credible reporting.
