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 176 days ago. Ages are as of when this page was built.

About this market

Final prediction market prices for "How many different countries will Israel strike in April?". 2 last traded at 97.4%. Next is 3 at 2.5%. $159K has traded across 3 outcomes on Polymarket. The market closed on Apr 30, 2026.

This market will resolve according to the total number of different sovereign UN member states' soil that Israel initiates a drone, missile, or air strike between April 1, 2026, 12:00 AM ET and April 30, 2026, 11:59 PM ET. Strikes on embassies or consulates will count towards the country where the embassy or consulate is located, not towards the country they represent. Strikes within the territory controlled by Israel as of market creation, as well as strikes within the West Bank or the Gaza Strip, will not be counted towards this market's resolution. 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 Israeli military forces that impact another country's ground territory that is officially acknowledged by the Israeli government or a consensus of credible reporting. Missiles or drones that are intercepted and surface-to-air missile strikes will not count towards the resolution of this market, regardless of whether they land on another country's 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 Israeli ground operatives will not qualify. 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.
