About this market

Live prediction market odds for "Israel ground operation in Iran confirmed by...?". December 31 leads at 15.5%. $1.8M has traded across 1 outcome on Polymarket. The market is expected to resolve by Jan 1, 2027.

This market will resolve to "Yes" if participation by Israeli military personnel in a ground operation in Iran on or after February 28, 2026, is confirmed by the specified date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A "ground operation" is defined as a military operation that involves Israeli military ground forces conducting operations within Iranian territory. For the purposes of this market, aerial and maritime operations will not be considered. Only operations involving Israeli troops on the ground within the terrestrial territory of Iran will qualify. Official confirmation by the Israeli military of personnel operating on the ground within Iranian territory during the specified timeframe will resolve this market immediately. An overwhelming consensus of credible reporting confirming that the Israeli military personnel operated on the ground within Iranian territory durring the specified timeframe will also suffice. Qualifying confirmations include statements such as the June 25, 2025, statement by IDF Chief of Staff Lt.-Gen. Eyal Zamir confirmed that Israeli commando forces operated covertly on the ground inside Iran during the 12-day war. Confirmations referring only to non-military Israeli intelligence activity, including operations by the Mossad or Shin Bet, as well as airstrikes, cyberattacks, standoff weapons, remote sabotage, or actions by proxies or third parties without Israeli military presence, will not alone qualify. Incidents that would not alone suffice include the November 2025 Mossad statement indicating its agents were present during protests in Iran, or the July 31, 2024, assassination of Hamas leader Ismail Haniyeh in Tehran, widely attributed to Mossad agents. The primary resolution source for this market will be official information by the Israeli military; however, an overwhelming consensus of credible reporting will also 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.
