Intro

This market tracks whether the United States and Iran will achieve an effective ceasefire by maintaining a continuous 14-day period without qualifying military actions through August 14. On Polymarket, the current probability for a ceasefire is 100%. Resolution will be based on official information from the governments and militaries of the United States and Iran and credible reporting. Watch for developments around August 14, the specified end date for the ceasefire period.

Polymarket

This market will resolve to “Yes” if there is a continuous 14-day period during which the United States does not take a qualifying military action against Iran that begins at any time between market creation and the specified end date, 11:59 PM ET. Otherwise this market will resolve to “No.” The first day of the 14-day period will be the calendar date (ET) after the most recent qualifying military action (or the date of market creation, if no qualifying action has occurred). The period runs through 12:00 PM ET on the 14th calendar day. This market resolves to “Yes” if any such period is completed where the most recent qualifying military action occurred on or before the specified end date (ET). A qualifying military action refers to an air strike or a surface-to-surface missile strike, initiated by the United States, that directly impacts Iran. 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 Iran do not constitute a military action regardless of any damage incurred. A military action will be considered to impact Iran if it directly impacts the terrestrial territory of 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 Iran 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 (ET) 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, the action will be judged 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 the United States and Iran and credible reporting.

Frequently asked questions

On Polymarket, the US-Iran ceasefire market dashboard displays real-time odds and price history for whether an effective ceasefire between the US and Iran will occur by the specified deadline. Traders can monitor how market sentiment shifts as new developments emerge, with volume data reflecting the level of trading activity. The dashboard aggregates all positions and trades on this single venue, giving you a live snapshot of what participants believe about the likelihood of this geopolitical outcome. You can track price movements over time to see how major announcements or diplomatic signals influence market expectations.

Prediction market odds often diverge from traditional analyst forecasts because they reflect real-money incentives—traders who bet incorrectly lose capital. While political analysts and think tanks may issue point estimates based on historical patterns and expert judgment, this market aggregates the collective belief of participants actively trading on the outcome. Analysts sometimes anchor to baseline assumptions or institutional constraints, whereas market prices adjust continuously as new information arrives. Comparing the two can reveal where expert consensus and market sentiment align or diverge, offering a useful cross-check for understanding the true uncertainty around a US-Iran ceasefire.

On Polymarket, this market is priced through an automated market maker that converts trader positions into real-time odds. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the cumulative bets placed by all participants, with higher prices indicating greater perceived likelihood. As traders buy or sell shares, the price adjusts automatically to balance supply and demand. This mechanism ensures that the market price incorporates all available information and the collective judgment of active traders, making it a dynamic and responsive gauge of expectations around a potential ceasefire.

This market resolves around Aug 31, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution hinges on whether an effective ceasefire between the US and Iran meets the specified criteria by that deadline. Traders should monitor official statements, diplomatic channels, and reputable news sources as the date approaches. Once the outcome is determined and verified, the market will settle and winning positions will be paid out according to the final result.

Major diplomatic announcements, military incidents, or statements from US or Iranian officials could significantly shift market odds. Ceasefire negotiations, UN involvement, or statements from regional allies may trigger sharp price movements. Economic sanctions changes, proxy activity in contested regions, or public declarations of intent from either government could also influence trader sentiment. Media reports of back-channel talks or failed negotiations often cause volatility. Traders should watch for unexpected escalations or de-escalation signals, as these typically generate the largest swings in market pricing as participants reassess the probability of an effective ceasefire by the deadline.
