About this market

Live prediction market odds for "Next US-Iran senior diplomatic meeting by...?". Before Apr 1, 2027 leads at 70.5%. Next is Before Mar 1, 2027 at 42%. $861K has traded across 9 outcomes on Polymarket and Kalshi. The market is expected to resolve by Oct 31, 2026.

On September 22, U.S. Special Envoy Steve Witkoff and Jared Kushner met Iranian Foreign Minister Abbas Araghchi on the sidelines of the UN General Assembly in New York, with President Trump saying another meeting is scheduled in the near future.(see: https://www.israelhayom.com/2026/09/22/witkoff-kushner-attended-us-iran-meeting-another-expected-soon). This market will resolve to “Yes” if there is a direct or indirect senior-level diplomatic meeting between the United States and Iran by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”. A diplomatic meeting occurs when representatives of both listed countries who are acting in an official capacity and are authorized to engage in diplomacy on behalf of their respective governments or governing authorities deliberately meet for the purpose of diplomacy or negotiation. A qualifying meeting need not result in any agreement, joint statement, or further engagement. A diplomatic meeting is senior-level if each listed entity is represented by a head of state, a head of government, or a vice president; a foreign minister; a minister of cabinet rank; the secretary or head of a national security council; the presiding officer of a national legislature; a special envoy; or another individual designated by the head of state or head of government to conduct diplomatic negotiations on their behalf. Individuals authorized only for technical, implementation, monitoring, staff-level, preparatory, or working-group-level talks will not be considered designated to conduct diplomatic negotiations on behalf of the head of state or head of government. This definition includes, but is not limited to, all of the following individuals: for the United States, Donald Trump, JD Vance, Marco Rubio, Scott Bessent, Steve Witkoff and Jared Kushner; and for Iran, Mojtaba Khamenei, Masoud Pezeshkian, Abbas Araghchi and Mohammad Bagher Ghalibaf. In each case, a qualifying representative must participate in the meeting. A direct meeting refers to a diplomatic meeting where the representatives of both countries directly interact with each other in person. Meetings conducted through translators qualify, provided direct, face-to-face communication occurs. An indirect meeting refers to a meeting conducted indirectly through designated mediators or facilitators. A qualifying indirect meeting must meet both of the following criteria (i) the designated intermediaries act with the knowledge and authorization of both entities; (ii) representatives of both entities are physically present in the same facility, venue, or city as part of a single organized round of talks convened for the purpose of diplomatic engagement, with the intermediary conveying communications between the representatives or delegations on the same day. “The same day” means the same calendar day local time at the meeting location. Sessions, proceedings, or convenings of standing international organizations, treaty bodies, or recurring multilateral summits or conferences (e.g., the United Nations General Assembly, G7, and G20 summits) do not qualify, unless a qualifying and deliberate diplomatic meeting between representatives of the listed countries is separately held alongside such a convening. The following do not qualify as either a direct or indirect diplomatic meeting: chance encounters; standalone exchanges limited to greetings, courtesies, or photo opportunities; meetings conducted remotely, by telephone, or by any other means where the relevant representatives are not physically present at the same facility, venue, or city on the same day; discussions involving persons not authorized to engage in diplomacy or negotiation on behalf of their respective governments. The resolution sources for this market will be official information from the governments of the United States and Iran and 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.
