Market context
Kharg Island is still firmly treated as an Iranian-controlled oil hub, and that is why the market’s current **0% YES** pricing looks like the heavy favourite. The island handles roughly 90% of Iran’s crude exports and has done so for decades, with deepwater terminals built for very large tankers and no sign in the supplied material of any alternative authority taking over primary governmental or military control.[1][2][3]
For handicapper context, this is a classic *regime-control* market rather than a pure infrastructure-damage bet. Comparable cases are rare: even severe strikes, sabotage, or temporary disruption to energy infrastructure do not normally amount to loss of sovereignty, and the market rules explicitly exclude raids, landings, bombardment, offshore naval pressure, or short-lived interruptions. That makes the underdog path far narrower than a simple attack-on-site headline would suggest.[1][6][17]
The main catalysts to watch are any formal Iranian or coalition announcements about occupation, de facto administration, or a handover of port and military functions, plus any credible reporting of a sustained amphibious or ground campaign tied to a recognised authority. Recent coverage has kept Kharg in the frame as a strategic target and oil choke point, but the reporting is about leverage and vulnerability, not transfer of control.[10][15][16] On that basis, consensus sits with **No**, while any value on **Yes** would have to rest on an extreme escalation and an actual change of control before the 2026-03-31 settlement window closes.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.
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.
