Israel x Iran ceasefire continues through 2026?

Platform comparison

Market context

Israel and Iran have maintained an undeclared ceasefire since April 2024, following Iran's direct missile and drone attack on Israeli territory and Israel's subsequent limited retaliatory strikes. The arrangement, mediated indirectly through regional intermediaries, has held despite ongoing proxy conflicts in Gaza, Lebanon, and Yemen. This market tests whether that restraint persists through August 2026—a window that encompasses potential Israeli elections, Iranian leadership transitions, and the full trajectory of the Gaza conflict's diplomatic resolution.

Historical precedent suggests such ceasefires between these adversaries are fragile but durable when both sides face offsetting costs. The 2015–2019 period saw no direct Israeli-Iranian military exchanges despite sustained proxy activity, whilst the 2006–2008 interval between the Second Lebanon War and Operation Cast Lead involved similar de facto separation. The 97% implied probability reflects market confidence in continued strategic restraint, though this sits notably higher than consensus among regional analysts, who typically assign 80–85% probability to maintenance through 2026. Sportsbooks have not yet priced this contract, limiting cross-platform comparison.

Traders should monitor announcements regarding Israeli settlement expansion in occupied territories, Iranian nuclear programme developments, and any escalation in Houthi attacks on shipping—each has previously triggered tit-for-tat cycles. The International Atomic Energy Agency's quarterly reports on Iranian enrichment levels and any statements from Israel's defence ministry regarding Iranian military capabilities will signal shifting threat perceptions. Lebanese Hezbollah's reconstruction timeline and US policy shifts under new administrations represent secondary catalysts that could alter the calculus for either party.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
