Israel x Iran ceasefire continues through 2026?

Platform comparison

Market context

Israel and Iran have maintained a de facto ceasefire since April 2024, following Iran's direct missile and drone strike on Israeli territory and Israel's subsequent limited retaliatory strikes. This market asks whether that pause in direct military exchanges will hold through 31 August 2026. A YES share pays out if neither country conducts air strikes or surface-to-surface missile strikes against the other during the settlement window; a NO share pays out if either party initiates such an attack. The 97% crowd probability reflects confidence in the ceasefire's durability, though that figure compresses significant tail risk into a narrow margin.

Historical precedent offers mixed signals. The 2015 nuclear agreement (JCPOA) created a 12-year period of reduced direct confrontation, though proxy conflicts continued throughout the Gulf region. However, the 2020 assassination of Iranian general Qasem Soleimani by Israeli strike and Iran's subsequent ballistic missile response demonstrated how quickly escalation can occur when red lines are crossed. The current ceasefire differs in that both parties appear to have accepted mutual deterrence rather than pursuing a negotiated settlement, a posture vulnerable to miscalculation or domestic political pressure.

Traders should monitor developments around nuclear negotiations, Israeli domestic politics ahead of potential 2026 elections, and Iranian regional activities in Syria and Lebanon. Recent reporting from Reuters and AFP has highlighted ongoing indirect tensions through proxy forces, particularly Houthi attacks on shipping and Israeli operations in Syria. Any significant shift in US Middle East policy following the 2024 American election could alter incentive structures for both parties. The settlement window extends 20 months from typical market creation, providing ample time for unforeseen triggers.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
