Odds by venue

Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.

Prices come from our regular polls of each venue, the oldest 196 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "Military action against Iran ends on...?". April 9 last traded at 96.4%. Next is April 10 at 1.4%. $6.8M has traded across 23 outcomes on Polymarket. The market closed on Apr 30, 2026.

This market will resolve according to the next date Iran Standard Time (GMT+3:30), on which neither the US nor Israel initiates a drone, missile, or air strike on Iranian soil or any official Iranian embassy or consulate. 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. If strikes could be verified under the prior rule for each listed day, this market will resolve to "Military action through April 30." 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.
