LATEST: Prediction market Kalshi has been sued for allegedly failing to pay out $54M to users who bet that Iranian Supreme Leader Ayatollah Ali Khamenei would leave office before March 1, 2026. Co-founder Luana Lopes Lara says the headline is misleading, adding: “All users in this market were made whole by Kalshi with out-of-pocket reimbursements.”(CoinDesk)
