Market context

Kharg Island, Iran's primary crude oil export terminal in the Persian Gulf, would need to fall under sustained control of a foreign power or occupying force by end-March 2026. The crowd currently assigns this outcome zero probability, reflecting the island's strategic importance to Iran's economy and its position within Iranian territorial waters roughly 25 kilometres from the mainland coast.

Historical precedent suggests such territorial shifts require either major military defeat or negotiated settlement. Iraq held the Falkland Islands analogy inverted: Argentina's 1982 invasion lasted 74 days before British recapture. More relevant, Iraq's seizure of the Shatt al-Arab waterway during the Iran–Iraq War (1980–88) involved years of grinding conflict and ultimately returned to Iranian control via ceasefire. Kharg Island itself survived Iraqi air and missile strikes throughout that war but remained Iranian-held. The 0% probability reflects the absence of any credible military force positioned to invade and hold the island against Iranian resistance within a 15-month window.

Catalysts would centre on regional escalation: direct Israeli strikes on Iranian oil infrastructure (Kharg has been targeted before, in 1987 and 2019), US military action, or a broader Gulf conflict. Recent tensions over the Strait of Hormuz and Iranian nuclear negotiations create background risk, though no current announcements suggest imminent military operations targeting territorial control. The settlement definition requires sustained governmental or military control by another state—temporary bombardment or raids do not qualify—a high bar that explains the market's consensus.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), 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.
