US x Iran permanent peace deal by 2026?

Market context

Washington and Tehran are still in indirect talks, but there is no signed framework for a permanent end to hostilities. Reporting in mid-April said the US was “optimistic” about a possible peace deal after Pakistan-mediated contacts, yet the same reports also noted sharp disagreements over Iran’s nuclear programme and wider security terms. That leaves the market at 0% for a reason: the existing diplomacy has produced cautious language and ceasefire management, not the kind of explicit, durable settlement the contract requires.

Comparable US-Iran openings have repeatedly stalled once the talks move from general principles to verification, sanctions relief and nuclear limits. In February, both sides described renewed discussions as positive, but subsequent coverage said the gap remained wide, with Iran seeking immediate sanctions relief and the US pushing tougher conditions. More recent briefings suggest the pattern has not changed, with reports of draft parameters and back-channel messaging but no agreed text ending military hostilities on a lasting basis.

The key catalysts are any new announcement from US, Iranian or Pakistani mediators, plus whether they set a date for another round of talks. Traders should also watch for changes in the ceasefire environment, because the market depends on an agreement that clearly states hostilities have ended permanently, not a temporary pause. If negotiations resume, the wording will matter as much as the meeting itself: a memorandum, phased truce or enrichment-only understanding would not obviously satisfy the settlement terms unless it explicitly closes the conflict.

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.
