Israel x Iran ceasefire continues through 2026?

Platform comparison

Market context

Israel and Iran remain in a fragile ceasefire, and the market’s **100% YES** crowd view leaves no consensus debate about the base case. The handicapper’s read is that the favourite is the status quo: if both sides keep the current restraint, the contract resolves YES, but any air strike or surface-to-surface missile strike by either state against the other would flip it to NO.

The main historical guide is that these arrangements can survive early friction but still remain vulnerable to renewed fire later. In the 2026 ceasefire that followed the Twelve-Day War, there were initial violations by both sides, yet the ceasefire held for months before bombing resumed on 28 February 2026, which is a reminder that the first hurdle is not the only one.[1] AP also reported that the recent ceasefire was narrowly framed around stopping military actions, with hostilities continuing even after the announcement before the pause settled in.[3] That favours the Yes side, but it also means the price is heavily concentrated on a single assumption: no qualifying strike occurs before the August 2026 deadline.

For traders, the catalysts are the same ones that have broken prior pauses: public claims of retaliation, air-defence alerts, missile launches, and any announcement that one side has resumed operations. Watch especially for developments around the Strait of Hormuz and any diplomatic messaging that ties maritime access or third-party mediation to the ceasefire terms, since recent reporting said the arrangement hinged on halting attacks and keeping shipping open.[2][7] The market is priced as though a breach is extremely unlikely, so the only real value spot is contrarian: a small No case if you think rhetoric, proxy pressure, or an isolated strike could still produce a qualifying incident before settlement.[3]

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.
