Israel x Iran ceasefire continues through 2026?

Platform comparison

Market context

The ceasefire between Israel and Iran has held since April 2024, following Iran's direct missile and drone strikes on Israeli territory and the subsequent Israeli response. This market tests whether that fragile truce survives through August 2026—roughly two years of restraint between two adversaries with a history of tit-for-tat escalation. The 97% implied probability reflects market confidence in continued de-escalation, though the settlement definition is narrow: only direct air strikes or surface-to-surface missile strikes count as qualifying military actions, excluding proxy activity, cyber operations, or conventional artillery.

Historical precedent suggests caution about such high confidence. Israel and Iran engaged in similar cycles of strikes and counter-strikes between 2019 and 2024, with periods of apparent calm punctuated by sudden escalation. The April 2024 exchange itself came after months of relative quiet following the January 2024 assassination of an Iranian general. Regional tensions have historically reignited around anniversaries, political transitions, or perceived threats to nuclear programmes. The 2026 window encompasses potential shifts in US policy following the 2024 presidential election, Israeli domestic political pressures, and Iranian responses to sanctions.

Traders should monitor statements from Israeli and Iranian military officials, developments in nuclear negotiations, and any incidents involving Israeli operations in Syria or Iraq that could trigger Iranian retaliation. Recent reporting from Reuters and AFP has tracked Iranian military posturing and Israeli air defence upgrades. The market's heavy favourite status leaves limited value for YES bettors; contrarian interest would focus on flashpoints—particularly around mid-2025 if US policy shifts substantially—where the 3% NO probability may underestimate tail risks of renewed direct confrontation.

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.
