Resolution criteria on PolyGram: This market will resolve to "Yes" if there is a diplomatic meeting between the listed individual, acting as a representative of the United States, and representatives of Iran by June 30, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. To qualify, the listed individual must be physically present at the meeting and actively participate as a negotiator representing the United States. 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.

Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| Donald Trump | 7% YES | 93% NO |
| J.D. Vance | 14% YES | 86% NO |
| Jared Kushner | 33% YES | 68% NO |
| Marco Rubio | 12% YES | 89% NO |
| Steve Witkoff | 44% YES | 56% NO |
The question hinges on whether Steve Witkoff, Trump's Middle East envoy and incoming White House Chief of Staff, will conduct direct diplomatic talks with Iranian officials by the end of June 2026. Such a meeting would require both parties to agree to formal negotiations, with Witkoff physically present and actively negotiating on behalf of the United States. The 7% implied probability on Polymarket's order book reflects substantial scepticism about this outcome materialising within the 18-month window.
Historical precedent suggests direct US-Iran diplomatic engagement remains rare and contingent on significant geopolitical shifts. The last substantive bilateral talks occurred under the Obama administration, culminating in the 2015 JCPOA. Trump's first term saw maximum pressure and no direct negotiations. Witkoff's appointment signals potential openness to Middle East diplomacy, but Iran's current posture and domestic constraints in both capitals make formal talks unlikely without a major catalyst—such as a nuclear crisis, regional conflict escalation, or explicit policy reversal by the Trump administration.
Traders should monitor announcements regarding US sanctions policy, Iranian nuclear programme developments, and any public statements from either government about diplomatic channels. The timing of UN General Assembly sessions, potential Israeli-Iranian escalations, and statements from Witkoff himself will signal whether conditions are shifting. Recent reporting from Reuters and other outlets has emphasised the Trump team's focus on Israel and Gulf states rather than Iran engagement, which supports the current low probability. Any shift in rhetoric or leaked diplomatic overtures would likely move the market sharply.

The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
