Market context

Polymarket is pricing this contract at **0% YES** today, which means the market is effectively saying there is no visible setup yet for a named person to show up at the next US–Iran diplomatic meeting before the 30 June deadline. On Polymarket, that trade is backed by USDC on Polygon and settles through conditional tokens, so the key question is not whether diplomacy exists in general, but whether a specific attendee is publicly tied to the next official meeting.

The recent pattern is useful context: US–Iran talks have repeatedly been announced, delayed, or shifted in format, which makes attendance markets harder to price than simple “will talks happen?” contracts. Reuters reported on 18 April that Iran said no date had been set for the next round of negotiations with the US, after earlier high-level discussions in Islamabad ended without agreement[4]. By late February, Oman had said the next round would be in Geneva, and reports at the time suggested Steve Witkoff was expected on the US side[1]. That kind of stop-start diplomacy matters because this market only resolves on a real meeting involving authorised representatives, not on mediated contacts or broad diplomatic signalling.

For traders, the main catalysts are official venue and date announcements, mediator statements from countries such as Oman, Pakistan, or Switzerland, and any confirmation of who will actually attend. Polymarket’s own market commentary has pointed to continued mediated engagement and to a memorandum of understanding for a new round of formal talks, but these setups can still slip if the parties disagree on sequencing or the agenda[2][3]. The clearest swing factor is a fresh Reuters-style confirmation naming an attendee and location; without that, the 0% pricing reflects how little time remains and how many prior rounds have stalled before a face-to-face meeting was locked in[4][5].

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket UK, which mirrors the Polymarket order book directly.

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.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on Polymarket UK?

Zero. Polymarket UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

Not under $1,500 of lifetime trading volume. Above that threshold, Polymarket UK triggers a quick verification flow that finishes in minutes.
