Farsi, Hengam, Hormuz or Kharg Island no longer under Iranian control by 2026?

Platform comparison

Market context

Iran still controls Farsi, Hengam, Hormuz and Kharg, and the market’s 2% YES price implies traders see a change in sovereignty or effective military control as a tail event rather than a base case. On the available information, there is no evidence of an armed contest for these islands, and Farsi in particular is documented as an Iranian island with an IRGC Navy base, while the 1968 Saudi-Iran agreement explicitly recognised Iranian sovereignty over Farsi.[1][2][13]

That low probability is broadly consistent with the historical record: comparable cases usually involve formal transfer, prolonged occupation, or a recognised authority replacing the incumbent, not brief incursions or a single incident. The closest analogue in the source set is the 2016 Farsi Island detention of U.S. sailors, which was a temporary seizure of personnel and vessels near the island, not a transfer of control; the market rules also exclude raids, landings, sabotage, offshore presence and other short-lived disruption from settlement.[15][16][12]

For traders, the main catalysts are any credible shift in territorial control, not routine military signalling. Watch for official statements from Tehran or rival states, treaty or ceasefire terms that actually hand over administration, and any credible reporting of a garrison change, blockade collapse or internationally backed occupation; absent that, the contract should remain anchored near the low single digits. The current odds also appear to sit well below the kind of pricing that would follow even a serious escalation warning, suggesting the market is treating this as an extreme geopolitical outcome rather than a live dispute.[12]
