Who will attend US-Iran signing ceremony?

Platform comparison

Market context

On 14 June 2026, the United States and Iran confirmed a written diplomatic agreement, with an official signing ceremony scheduled for 19 June in Geneva, Switzerland, though location details later shifted to the secluded Burgenstock resort overlooking Lake Lucerne. Despite the initial announcement, subsequent reports indicate the ceremony may be sealed remotely, with Iran’s foreign ministry stating the event is off and White House arrangements for technical talks remaining unconfirmed.

Historically, high-stakes diplomatic signings between adversaries rarely involve top-tier leaders attending in person; comparable cases, such as the 1973 Paris Peace Accords or the 2015 Iran nuclear deal, saw deputy ministers or foreign ministers as the primary signatories while presidents remained absent. This precedent frames the current 3% crowd-implied probability as plausible, given that President Trump and Iran’s President Pezeshkian have not been confirmed for attendance, and the only publicly linked Iranian official is the Deputy Foreign Minister.

Traders should monitor official announcements from Switzerland’s Foreign Ministry, the White House, and Iran’s Mehr News Agency for any reversal of the remote-signing stance or confirmation of senior regional figures like Pakistan’s Prime Minister Shahbaz Sharif or Qatar’s representatives, who are expected to attend. A recent CNBC report notes that the biggest signal will be whether Saudi Arabia or the UAE send cabinet-level delegates, as their presence would significantly alter the odds of a listed individual attending the ceremony.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
