This market tracks whether a ceasefire between Israel and Iran will hold through August 31, according to Polymarket using official government and credible reporting as its resolution source. The current probability that the ceasefire continues stands at 93.5%. All eyes are on the August 31 deadline, which marks the end of the betting period and the point at which the market will resolve based on whether any qualifying military action has been taken by either side. The market will ultimately settle on December 31, 2026 if a definitive determination has not yet been reached.
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.
Prediction markets and traditional polling measure different things: polls capture public opinion at a snapshot in time, while markets aggregate real-money bets from traders with direct financial incentives to forecast accurately. For geopolitical events like ceasefire duration, prediction markets often incorporate breaking news, diplomatic signals, and expert analysis faster than polls can update. Traders betting on this market face direct consequences for incorrect predictions, which tends to produce more disciplined probability estimates than survey responses. However, both approaches have value—polls reflect broader sentiment, while market odds reveal the consensus of informed participants willing to stake capital on their conviction.
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. Traders buy and sell shares representing "yes" or "no" outcomes, and the price of each share reflects the collective probability assigned by the market. As more capital flows into one side, the price adjusts automatically to balance supply and demand. The current odds for the leading outcome stand at 95.5%, meaning traders are pricing in that probability for the ceasefire to continue through the specified date. Transaction costs and slippage vary based on trade size and market depth.
This market resolves around Dec 31, 2026, at which point the outcome will be determined by whether the ceasefire between Israel and Iran remains in effect through the target date. Resolution will be verified against credible public sources and official statements from relevant parties. Traders holding winning positions will receive payouts proportional to their stake, while losing positions expire worthless. The exact resolution hinges on whether any significant military escalation, formal ceasefire breakdown, or resumption of hostilities occurs before the deadline. Until that date, the market remains open for trading as new developments influence trader expectations.
Several categories of events could shift odds in this market significantly. Direct military incidents—airstrikes, missile launches, or cross-border attacks—would likely trigger sharp price moves toward lower ceasefire probabilities. Diplomatic announcements, mediation breakthroughs, or formal agreements could strengthen confidence in the ceasefire's durability. Political leadership changes, domestic pressure from hardliners, or proxy activity could introduce uncertainty. International sanctions, weapons transfers, or statements from major powers like the US or regional allies may also influence trader sentiment. Economic developments, humanitarian crises, or UN actions could reshape the risk calculus. Traders monitor news flows, expert commentary, and historical precedent to adjust positions as the geopolitical landscape evolves.
