About this market

Final prediction market prices for "Trump announces US x Iran ceasefire broken by...?". April 21 last traded at 31%. Next is April 14 at 16%. $151K has traded across 2 outcomes on Polymarket. The market closed on Apr 14, 2026.

On April 7–8, 2026, the United States and Iran agreed to a temporary two-week ceasefire aimed at halting direct hostilities and de-escalating the ongoing conflict. This market will resolve to "Yes" if President Trump, the US government, or the US military publicly and officially announces that the ceasefire between the United States and Iran has been broken or violated by either the United States or Iran by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No." Qualifying statements must clearly and explicitly indicate that either the United States or Iran has violated or broken the ceasefire, or use equivalently definitive language unambiguously signaling that a breach of the ceasefire has occurred. A statement that either party is no longer committed to the ceasefire is not required. Statements that merely describe actions inconsistent with the ceasefire (e.g., "Iran closed the Strait of Hormuz") without explicitly labeling them as a breach or equivalent violation of the ceasefire will not alone suffice. Announcements that the ceasefire has been broken solely in the context of actions by Israel (e.g., "Israel/Hezbollah broke the ceasefire"), without any indication that the United States or Iran has broken the ceasefire, will not qualify. Informal announcements, statements from unnamed sources, or leaks do not qualify. Written public statements from Donald Trump (e.g., posts from his personal Truth Social account) will qualify. Videos posted on his social media accounts will also qualify for a "Yes" resolution. The primary resolution source for this market will be official statements from the US government and/or its official representatives; however, a consensus of credible reporting may also be used. Note: this market will resolve solely based on whether a qualifying announcement is made within the specified timeframe. Whether the United States withdraws from the ceasefire agreement or whether hostilities resume will not be considered.

Questions

What does the consensus price mean?

It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.

How is the payout worked out?

A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.

Why do the venues show different prices?

Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.

Is a price gap an arbitrage?

Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.

How fresh are these prices?

Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
