US x Iran permanent peace deal by 2026?

Market context

The United States and Iran have maintained no formal diplomatic relations since 1980, with hostilities ranging from proxy conflicts in Iraq and Syria to direct military exchanges following the 2020 assassination of Qasem Soleimani. A permanent peace deal would require explicit mutual recognition of a lasting ceasefire and end to military operations, distinguishing it from temporary ceasefires or partial agreements like the 2015 Joint Comprehensive Plan of Action (JCPOA), which addressed nuclear matters but not broader military hostilities. The current 0% probability reflects the structural distance between the parties: the US maintains regional military presence and sanctions architecture, whilst Iran's leadership has historically tied negotiations to sanctions relief and recognition of its regional role.

Historical precedent suggests such agreements emerge only after sustained diplomatic infrastructure and third-party mediation. The 1991 Madrid Conference and subsequent Oslo Accords took years of back-channel work; the 2022 China-brokered Iran-Saudi normalisation took months of quiet negotiation in Oman. Traders should monitor US presidential transitions (the 2024 election shapes negotiating posture through 2026), Iranian domestic politics around elections scheduled for 2025, and any UN-mediated talks. Recent reporting from Reuters and AP News indicates no active peace track as of late 2024, though regional stability shifts—particularly in Syria following Assad's fall in December 2024—could alter incentive structures for both governments.

For programmatic monitoring, traders would track diplomatic announcements from the State Department, Iranian Foreign Ministry statements, and UN envoy activities. Conditional orders tied to specific catalysts (formal talks announced, sanctions relief proposals, third-party mediation initiated) would capture entry points before crowd probability shifts. The settlement window extends through end-2026, allowing two years for either party to initiate formal negotiations, though the absence of current dialogue channels makes near-term movement unlikely.

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.
