Market context

Israel and the United States launched a full-scale strike campaign into Iranian territory on 28 February 2026, marking the start of the Twelve-Day War and a dramatic escalation in regional conflict[2][9]. This military action, which targeted Iran’s nuclear facilities including the Arak heavy water plant, triggered a massive retaliatory barrage from Tehran across multiple Gulf states[3]. The event fundamentally altered the geopolitical landscape, with Iran subsequently attacking all six Gulf Cooperation Council nations—Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the UAE—demonstrating how quickly a single strike can cascade into multi-country involvement[2].

Historically, Israel’s 2024 and 2025 operations remained largely confined to Lebanon, Syria, and Gaza, rarely exceeding two or three sovereign territories per year. The 2026 Iran war, however, broke this pattern by directly engaging a new major adversary and drawing in neighbouring states through retaliatory dynamics. With the current crowd-implied probability of a strike in 2026 sitting at 0% YES, the market appears to be ignoring the precedent set by the February campaign, which already saw Israel initiate aerial attacks on Iranian soil—a country not previously struck in this manner in recent decades[1][2].

Traders should monitor upcoming announcements from the Israeli Defence Ministry regarding further operations in Lebanon’s Beqaa Valley and potential responses to Houthi involvement, which has now entered the conflict[3][8]. Key dependencies include US-Israeli coordination schedules, Iranian retaliation thresholds, and any new intelligence on nuclear site readiness that could prompt additional strikes[6]. Recent reports confirm that Iran has fired projectiles toward Kuwait, Bahrain, Saudi Arabia, and the UAE, suggesting the region remains volatile and prone to further escalation[4]. The divergence between sportsbook lines, which often lag in geopolitical updates, and the 49% Polymarket probability assigned to “4” countries being struck highlights a meaningful gap in market consensus[1].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
