Who will attend US-Iran signing ceremony?

Market context

The US and Iran announced a written diplomatic agreement on 14 June 2026, with a signing ceremony scheduled for 19 June. This market resolves affirmatively if a specified individual attends an official ceremony where authorised representatives of both nations physically execute or formalise the accord by 7 July 2026. The settlement window allows a fortnight beyond the announced date, accommodating potential rescheduling or delayed ceremonial events.

Historical precedent suggests attendance at high-level US-Iran diplomatic signings remains volatile. The 2015 Joint Comprehensive Plan of Action (JCPOA) signing in Vienna saw limited US Cabinet presence, with Secretary of State John Kerry attending but President Obama remaining absent. The subsequent 2018 US withdrawal under the Trump administration underscores how political shifts reshape participation calculus. Current 41% implied probability reflects genuine uncertainty: formal agreements between these nations often face domestic opposition in both capitals, which can manifest as reduced official attendance or symbolic absences by key figures.

Traders should monitor official announcements regarding attendee lists, which typically emerge 48–72 hours before ceremonial events. Watch for statements from the US State Department and Iranian Foreign Ministry confirming participation levels. Schedule changes, security concerns, or last-minute diplomatic friction could trigger postponement beyond the 7 July deadline. Recent reporting from Reuters and AP News on the agreement's reception in Congress and Tehran's parliament will signal whether political headwinds might discourage high-profile attendance. Any public statements from the individual in question regarding their participation status constitute material information for resolution.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
