The Senate has approved a bipartisan resolution to prevent its members from using prediction markets. A resolution passed by voice vote Thursday bans senators and their staff from making bets on upcoming events. It's a change to the Senate’s rules, so it will go into effect immediately. Senate Minority Leader Chuck Schumer calls the move a “no-brainer” and he's encouraging the House and Trump administration to follow suit. The rule change comes as lawmakers increasingly voice concerns about prediction markets and people making wagers on current events, including the war with Iran.
