The rules provide detailed technical definitions for what constitutes a breach of the ceasefire, but a reader relying solely on the title might be surprised by specific exclusions. Only direct, unintercepted air strikes or surface-to-surface missile strikes impacting terrestrial land or internal waters count. Munitions intercepted in flight, falling debris or wreckage, cyber operations, naval gunfire, and rocket artillery are strictly excluded, meaning a strike that is entirely shot down or causes damage purely via falling fragments will not resolve the market to No. Resolution depends on a consensus of credible reporting and official military statements from both nations rather than a single primary source, and includes a three-day waiting window to evaluate conflicting claims if a potential strike occurs near the deadline.

Resolution rules

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.

Market explained

This market measures whether a ceasefire between Israel and Iran holds through December 31. Resolution relies on specific definitions of qualifying military actions, explicitly excluding intercepted munitions, falling debris, cyber attacks, ground operations, and minor tactical drone strikes.

How it resolves

The market resolves to Yes if a ceasefire remains in effect between Israel and Iran through December 31 at 11:59 PM Iran Standard Time (IRST). The market resolves to No if either Israel or Iran conducts a qualifying military action against the other's terrestrial territory or internal waters before that deadline. A qualifying action is an air strike or surface-to-surface missile strike directly impacting the other country. Munitions intercepted before impact, debris or wreckage from interceptions, surface-to-air missiles, small-arms fire, ground incursions, cyber operations, artillery, and minor drone strikes do not break the ceasefire. Resolution is determined by a consensus of official information from the Israeli and Iranian governments/militaries and credible reporting. If reports conflict, resolution may pause for up to 3 calendar days.
