Polymarket Resolution Criteria:
This market will resolve to "Yes" if there is a diplomatic meeting between representatives of the United States and Iran by the listed date, 11:59 PM ET. Otherwise, this market will resolve to “No”.
A diplomatic meeting refers to a deliberate meeting between representatives of the listed countries who are acting in an official capacity and are authorized to engage in negotiation or diplomacy regarding US-Iranian relations on behalf of their governments. Meetings conducted indirectly, for example, through designated mediators, facilitators, or interlocutors acting with the knowledge and authorization of the relevant governments, will qualify.
Brief greetings, chance encounters, or talks otherwise not deliberately aimed at diplomacy or negotiation will not count.
The meeting must be in-person (including indirect in-person meetings) and must be publicly acknowledged by either government or reported by a consensus of credible media. Remote meetings, phone calls, or other meetings where the relevant parties are not present will not count.
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.
1,000Source-context snapshot as of 2026-06-19T10:19:50Z, mapped to this market's in-person meeting criterion:
The White House identifies a June 17 MOU signing between the US and Iran at Versailles. That is relevant diplomatic context, but I would not treat a signing/photo/video alone as satisfying this market unless it also establishes an in-person direct or indirect meeting between authorized representatives.
China's MFA June 18 briefing records reports that the US president signed the first-stage MOU and that Iran's foreign ministry spokesperson said Tehran and Washington had finalized and signed it. Useful confirmation of agreement status, but still not by itself evidence of a qualifying in-person meeting.
The Guardian reported June 19 that the planned US-Iran talks in Switzerland were cancelled and that Vance was not traveling, while the White House still expected technical talks to begin as soon as possible.
Crux for the June 30 / July 31 answers: a publicly acknowledged Swiss/Oman/etc. in-person round, including indirect in-person talks through mediators, should be strong YES evidence. Remote signatures, calls, or a public MOU without a qualifying meeting are weaker under the written criteria.
