Market context

Kharg Island remains an Iranian-controlled oil terminal in the northern Persian Gulf, and for this market to go **Yes**, that control would have to pass to another state or internationally backed authority before the 31 March 2026 deadline.[2][3] The island is not a symbolic target: it handles roughly **90% of Iran’s crude exports**, so any genuine change in sovereignty or occupation would be an unusually large geopolitical event rather than a routine military incident.[3][6]

The closest historical frame is that markets should distinguish between *damage* and *control*. Reporting around March described US strikes on military sites and Iranian claims that export activity continued, which is materially different from an occupation or administrative handover.[1] That is why a **0% implied probability** can persist even after headlines about attacks: on Polymarket, the price is usually shown as an implied probability, while Kalshi and some exchange-style books quote in decimals and may differ on fees, KYC access, and whether UK-facing bettors can even reach the market directly.

Traders should watch for any formal announcement of an amphibious landing, a declared exclusion zone backed by a sustained occupation force, or a political transfer of authority over the island; short-lived raids, sabotage, or offshore bombardment do not qualify under the market rules. Bloomberg and other recent coverage have tied Kharg to broader Iran conflict and oil-price risk, but those catalysts only matter here if they produce a clear change in governance or military control rather than temporary disruption.[6][9]
