Kharg Island no longer under Iranian control by 2026?

Market context

Kharg Island, Iran's primary offshore oil and gas production hub in the Persian Gulf, would need to fall under sustained control by a foreign military power or internationally recognised authority by 31 March 2026 for this market to resolve affirmatively. The island hosts critical infrastructure supporting roughly 5% of Iran's crude output and remains a strategic asset within Iran's broader energy security framework. Establishing foreign control would require either a major military operation or a negotiated transfer—neither of which has materialised despite regional tensions.

Historical precedent suggests such territorial shifts occur through sustained occupation rather than temporary strikes. The 1980–88 Iran–Iraq War saw repeated attacks on Kharg Island, including Iraqi missile strikes that damaged facilities, yet Iran retained control throughout. More recently, the January 2020 U.S. strike on Qasem Soleimani and subsequent regional escalations did not translate into territorial losses. A comparable case would be the Strait of Hormuz chokepoint disputes, where military presence has fluctuated without changing sovereignty. The 0% crowd probability reflects the absence of credible military capability among regional actors to sustain an occupation against Iranian resistance.

Traders monitoring this market should track announcements regarding U.S.–Iran negotiations, Israeli military posture statements, and any formal coalition-building for Gulf security operations. Recent reporting from Reuters and regional defence analysts indicates no active military planning targeting Iranian territory. The settlement window's proximity to the current date—approximately 15 months—leaves minimal time for the geopolitical realignment such an operation would require. Programmatic traders would flag this as a tail-risk position, with triggers tied to major escalation announcements rather than routine military activity.

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.

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.
