Market context
Iran’s Kharg Island remains the regime’s primary oil export terminal, handling roughly 90% of its crude shipments, yet the crowd-implied probability that it will fall from Iranian control by March 2026 sits at just 1%. This figure reflects a stark divergence between prediction-market odds and the heightened geopolitical tension following US strikes on the island in mid-March 2026, which targeted Iran’s Islamic Revolutionary Guard Corps after it blockaded the Strait of Hormuz[2][3]. While sportsbook lines on broader Iran-conflict outcomes have tightened significantly, the specific contract on Kharg’s loss of control remains detached from the immediate violence, suggesting traders view temporary bombardment as insufficient to meet the market’s strict definition of permanent governmental or military displacement[2].
Historically, isolated attacks on energy hubs—such as the 2019 Saudi Aramco strikes or the 2022 Ukrainian port bombardments—have rarely resulted in permanent territorial loss unless accompanied by sustained occupation or internationally backed authority[2]. Comparable cases in the Persian Gulf, including the 1980s Tanker War, show that even heavy naval presence and sabotage do not equate to a state losing primary control unless an occupying force establishes enduring governance[2]. The current 1% probability aligns with this precedent: without evidence of a foreign ground invasion or UN-backed administration, the island’s strategic value alone does not guarantee a shift in sovereignty, even as the US continues to threaten its seizure[1][3].
Traders should monitor official US and Iranian announcements regarding the status of the Strait of Hormuz blockade and any scheduled naval deployments in the northern Persian Gulf, as these are the primary catalysts for potential territorial change[2]. A recent CNBC report notes that Kharg’s role as the economic lifeline for the IRGC makes it a persistent target, yet no credible source has confirmed plans for a ground occupation that would satisfy the market’s resolution criteria[4]. Until such a deployment is announced or an internationally backed authority establishes control, the island’s status as Iran’s oil hub remains intact, keeping the probability of loss of control firmly at the current low level[1][9].
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Best Prediction Markets, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
