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.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Best Value Play (Highest EV) Our model identifies October 31, 2026 as the premium value opportunity on the board. While the market only assigns it a 26% trading probability, our AI’s Fair Value assessment sits at 34.7% — yielding an impressive +8.7% EV Gap.
• Under-the-Radar Dark Horses Other notable discrepancies include September 30, 2026 (EV Gap: +5.9%). These long-tail opportunities are heavily discounted by the live order books despite stronger statistical backing from our predictive model.
