Congressional Probe Grows Over $500K Overnight Polymarket Bet Tied to Iran Strike

Rep. Mike Levin flagged a Polymarket bettor who reportedly turned about $87,000 into more than $515,000 overnight by betting on the U.S. strike on Iran, noting the first trade came 71 minutes before public news and urging transparency and oversight; Levin also cited Donald Trump Jr.'s ties to Polymarket as investigations were reportedly dropped, while Polymarket defended its prediction-market model as a forecasting tool amid billions traded on Iran-related markets.
