About this market

Final prediction market prices for "Military action against Iran ends by...?". April 30 last traded at 98.8%. Next is June 30 at 98.3%. $543K has traded across 4 outcomes on Polymarket. The market closed on Mar 31, 2026.

This market will resolve to "Yes" if neither the US nor Israel initiates a drone, missile, or air strike on Iranian soil or any official Iranian embassy or consulate on a full calendar day by the listed date, Iran Standard Time (GMT+3:30). Otherwise, this market will resolve to "No". If the date/time of a qualifying strike cannot be confirmed by a consensus of credible reporting by the end of the third calendar day after the listed date, the respective market will resolve to "Yes" regardless of whether a strike is later confirmed to have occurred. For the purposes of this market, a qualifying "strike" is defined as the use of aerial bombs, drones or missiles (including cruise or ballistic missiles) launched by US or Israeli military forces that impact Iranian ground territory or any official Iranian embassy or consulate (e.g., if a weapons depot on Iranian soil is hit by an US/Israeli missile, this will qualify). Missiles or drones that are intercepted and surface-to-air missile strikes will not be considered, regardless of whether they land on Iranian territory or cause damage. Actions such as artillery fire, small arms fire, FPV or ATGM strikes directly, ground incursions, naval shelling, cyberattacks, or other operations conducted by US/Israeli ground operatives will not be considered. The resolution source will be a consensus of credible reporting.

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.
