Senators ban themselves from prediction markets after candidates bet on own races

U.S. senators voted to ban themselves from prediction markets after a member was caught betting on his own re-election campaign, sparking a debate on insider trading loopholes. The ban, passed with a 68-31 vote, restricts trading on platforms like PredictIt and Polymarket for congressional members. This policy is stricter than the average insider trading rule for other financial markets, imposing a 15% cap on personal political bets.
