About this market

Final prediction market prices for "US x Iran ceasefire by...?". April 7 last traded at 100%. $274.8M has traded across 1 outcome on Polymarket. The market closed on Apr 7, 2026.

This market will resolve to “Yes” if there is an official ceasefire agreement, defined as a publicly announced and mutually agreed halt in direct military engagement, between the United States and Iran by the listed date, 11:59 PM ET. For the purposes of this market, an “official ceasefire agreement” requires clear public confirmation from both the United States government and the government of Iran that they have agreed to halt military hostilities against one another, or for an official ceasefire agreement to be otherwise confirmed to have been reached by an overwhelming consensus of media reporting. If the agreement is officially reached before the resolution date, this market will resolve to “Yes,” regardless of whether the ceasefire officially takes effect after the resolution date. Any form of informal understanding, backchannel communication, de-escalation without an announced agreement, or unilateral pause in hostilities will not be considered an official ceasefire. Humanitarian pauses, limited operational pauses, or temporary tactical stand-downs will not count toward the resolution of this market. A broader peace deal, normalization agreement, or political framework will qualify only if it includes a publicly announced and mutually agreed halt in military engagement between the United States and Iran, effective on a specified date, or otherwise confirmed by an overwhelming consensus of credible reporting. Agreements that outline future negotiations or de-escalation measures without an explicit, dated commitment to stop fighting will not qualify. This market’s resolution will be based on official statements from the United States government and the government of Iran. However, an overwhelming consensus of credible media reporting confirming that an official ceasefire agreement has been reached will suffice.

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.
