Israel x Iran ceasefire continues through 2026?

Platform comparison

Market context

The real-world event at the heart of this market is whether Israel and Iran will avoid launching air strikes or surface-to-surface missile attacks against each other through August 2026. In prediction markets, buying a YES share means you believe the ceasefire will hold, while a NO share bets it will break; the current 100% crowd-implied probability suggests traders see no immediate risk of escalation between the two states.

Historically, ceasefires between Israel and Iran have been fragile and short-lived. The Twelve-Day War ceasefire, announced in June 2025, held for months despite early violations but collapsed in February 2026 when bombing resumed [10]. A later US–Iran memorandum signed in June 2026 aimed for a 60-day permanent ceasefire on all fronts, including Lebanon, yet Israeli officials explicitly stated they were not bound to halt fighting with Hezbollah, and strikes in Lebanon continued shortly after the deal [2][11]. This pattern of partial compliance and overlapping conflicts frames why a 100% probability is unusually high for this region.

Traders should watch for official announcements from Israel’s Defence Ministry or Iran’s Revolutionary Guard, scheduled technical talks in Switzerland, and any flare-ups involving Hezbollah in Lebanon, which could trigger qualifying military actions [5][12]. Recent reports indicate the ceasefire is already under strain: a live diplomatic tracker flagged the deal as “dead” and “war resumed” as of 18 July 2026, citing unattended violations and booby-trapped terms [3]. Any new air strike or missile launch directly impacting either country would resolve the market to NO.

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.
