US-Iran Final Nuclear Deal by…?

Market context

The United States and Iran have already announced a written framework that starts a 60-day negotiation period on a final nuclear settlement, with sanctions relief and oil-export changes tied to compliance milestones.[1][3][4] That means the market is not pricing a distant hypothetical: it is weighing whether the June arrangement survives long enough to be converted into a qualifying instrument by 31 August.

Past Iran nuclear talks show that *interim understandings are easier than final paper*. The 2015 JCPOA took years of bargaining and was still politically fragile; more recent reporting on the 2026 framework stresses that key benefits such as frozen-asset releases, banking relief, and full sanctions rollback remain conditional rather than automatic.[2][3][4] A 1% crowd price therefore reflects not just geopolitical scepticism, but also the market’s usual discount for legal formality, domestic opposition, and the risk that technical talks on enrichment, inspections, and asset access stall before signature.

For traders, the immediate catalysts are any announcement from Geneva-style follow-up talks, confirmations of inspection access, and whether Washington and Tehran publish matching text rather than parallel statements. Reuters reported on 14 June that a final agreement would be deliberated over the following 60 days, while later coverage said oil-sanctions waivers and asset releases would be phased and contingent on progress.[4] In market terms, that matters because only deposits that actually reach the book can move the price: any snag around funding rails, fees, or withdrawal convenience can keep small probabilities sticky until larger traders move in. USDC tends to be the cleanest route for fast on-ramping, while SEPA and card-style options such as Klarna can broaden participation; that mix affects depth, but the resolution still turns on whether a signed instrument emerges before the deadline.

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.
