Kharg Island no longer under Iranian control by 2026?

Platform comparison

Market context

Polymarket prices this contract at **0% YES**, so the current market view is that Kharg Island is extremely unlikely to pass out of Iranian control before the 31 March 2026 settlement cutoff. On Polymarket, the contract is bought and sold in **USDC** on **Polygon**, with outcome exposure represented by conditional tokens; that means traders are effectively pricing the probability that a recognised shift in control, not just damage or disruption, occurs by expiry.

Kharg matters because it is not just any offshore site: it is Iran’s main crude export hub and a major revenue artery. Multiple recent reports put roughly **90%** of Iran’s crude exports through the island, with tankers loading there before transiting the Strait of Hormuz, and Reuters reported in March that U.S. forces destroyed military targets on Kharg while highlighting its importance and vulnerability.[1][13] That history is the key comparator for reading a near-zero price: even in periods of escalation, the island has been treated as critical infrastructure rather than as territory likely to change hands, and the market definition here is stricter than mere bombardment or temporary interruption.

For traders, the main catalysts are formal announcements about a transfer of authority, occupation, or internationally backed administration, plus any verified change in the island’s ground control rather than offshore strikes or sabotage. Watch for government statements from Tehran, U.S. or allied military briefings, and shipping or satellite indications of a sustained handover, because the settlement language requires Iran to no longer exercise primary governmental or military control. In the absence of such a development, even severe attacks on terminals or loading capacity would not be enough to resolve this market to Yes.[13][17]

Is Polymarket legal in the UK?
