Congress demands probe of pre-war prediction-market trades as insider-trading allegations mount

Congressional Democrats called for investigations into coordinated bets placed on Polymarket in the hours before the US launched Operation Epic Fury against Iran on February 28. A group of 38 anonymous accounts netted over $2 million on the Iran strikes after being preloaded with funds the preceding week, and a single account labeled "Magamyman" made $553,000 betting on Supreme Leader Khamenei's removal. Harvard researchers estimated $143 million in total profits on Polymarket by accounts with suspected insider knowledge of events ranging from the Iran war to diplomatic agreements.
