Kharg Island no longer under Iranian control by 2026?

Platform comparison

Market context

Iran’s Kharg Island remains firmly under Tehran’s military and governmental control, despite a significant US airstrike in March 2026 that destroyed military installations while deliberately preserving oil infrastructure. The island handles roughly 90% of Iran’s crude exports, making it the regime’s primary economic lifeline and a tempting target for adversaries seeking to choke off revenue flows to the Islamic Revolutionary Guard Corps [1][2].

Historically, similar strategic oil hubs in contested regions have rarely lost sovereign control unless a full-scale occupation or internationally backed authority establishes primary governance. Temporary raids, bombardments, or isolated landings—such as the March 13 US strikes that dismantled naval mines and missile bunkers without seizing the island—do not constitute a transfer of control [3]. Given that 90% of exports continue uninterrupted post-attack and no foreign force has occupied the territory, the current 1% crowd-implied probability aligns with analyst consensus that sovereign loss is highly improbable by March 2026 [2][5].

Traders should monitor official announcements regarding US or Israeli ground deployment plans, any new UN-backed occupation mandates, and shifts in Iran’s Strait of Hormuz blockade strategy, which could escalate conflict intensity. Recent reports confirm Centcom targeted over 90 military sites while explicitly avoiding oil facilities, reinforcing that the US objective remains disruption rather than territorial seizure [3]. Until a foreign state or internationally backed authority establishes primary control, Kharg Island will remain under Iranian sovereignty.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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 fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
