Market Discussion
As of August 31, 2026, Kharg Island remains under Iranian control, with officials dismissing claims of seizure and stating that oil operations continue despite a U.S. naval blockade and earlier reported U.S. military strikes on the island [1][2][3]. Consequently, a prediction market asking if Kharg Island would no longer be under Iranian control by August 31, 2026, would resolve to "No" [4].
