Where will the next US-Iran diplomatic meeting happen?

Market context

US and Iranian officials are still trying to keep talks alive after a run of indirect and direct contacts this year, and the next meeting’s venue remains the key market question. The current 38% crowd-implied probability points to a modest lean towards the most frequently floated host countries, rather than a settled expectation. Pakistan has already been reported as a possible venue for an earlier second round, while Geneva has also remained in the frame. That leaves the contract more open than a simple “yes” price suggests, because the next meeting could still move if the two sides choose a neutral intermediary location rather than a bilateral capital.

The historical pattern favours third-country meetings over either Washington or Tehran, and that is the main comparable to watch. Reuters and Euronews have both reported this spring that Islamabad and Geneva were under consideration for follow-up talks, with Pakistan said to have proposed hosting and the location, timing and delegations still undecided. That is the kind of setup where the market can swing quickly on a single communique: an announced venue, a confirmed travel itinerary, or even a mediated format can be enough to settle the country. Analysts broadly treat Geneva, Oman and Pakistan as the most plausible options, but no consensus has formed around one clear front-runner.

For traders, the immediate catalysts are formal read-outs from either government, mediator statements, and any confirmation from Oman, Pakistan or Switzerland that they are hosting or facilitating the next round. Watch for whether the meeting is described as direct or indirect, and whether it is scheduled as a continuation of the April and February sessions already held via intermediaries. If the process slips beyond a preliminary announcement and lands on a later date, the settlement window to 30 June means venue confirmation, not just negotiation intent, is what will decide the contract.

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 PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
