A surge of capital flowed into prediction markets like Polymarket and Kalshi over the weekend, as investors speculated on the impact of U.S. and Israeli airstrikes against Iran. This activity has sparked allegations of insider trading, with accusations on social media suggesting that some individuals used prior knowledge of the strikes to profit. In response to the controversy, Kalshi CEO Tarek Mansour announced that transaction fees would be refunded and positions established before the death of Khamenei would be liquidated at the last traded price. Despite these measures, many users expressed dissatisfaction, claiming they were misled by the platform. A White House spokesperson defended the Trump administration, stating its decisions are guided by the best interests of the American people.
