Kharg Island no longer under Iranian control by 2026?

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 military or occupying authority by end-March 2026 for this market to resolve affirmatively. The island hosts critical infrastructure for Iran's oil industry and remains heavily fortified; any transfer of control would require either a major regional conflict escalation or a negotiated handover—neither of which has materialised despite decades of geopolitical tension.

Historical precedent suggests extremely low probability within a 15-month window. The island has remained under Iranian sovereignty since the 1951 nationalisation of the Anglo-Iranian Oil Company, surviving the Iran-Iraq War (1980–88) when Iraq conducted repeated attacks but never captured it. Regional power shifts—including the 2003 Iraq invasion and subsequent US military presence—did not dislodge Iranian control of Kharg. A comparable case would be the Falkland Islands (1982), where military occupation required rapid force projection; however, no actor currently possesses both the capability and political will to mount such an operation against a fortified Iranian asset.

Traders should monitor escalations in US-Iran tensions, Israeli military operations in the region, and any formal declarations of conflict. Recent reporting from Reuters and regional defence analysts indicates no credible military planning for Kharg seizure. Programmatically, this market functions as a tail-risk hedge; conditional orders tied to major geopolitical announcements (UN resolutions, military mobilisations, or direct Iranian statements about territorial concessions) would be the primary entry signals. The 0% crowd probability reflects rational assessment of the timeframe's constraints rather than absolute impossibility.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
