Judith Levine argues in a Guardian opinion piece that prediction markets like Kalshi and Polymarket pose as populist wisdom of the crowd but are steered by a few skilled elites, with studies finding most casual traders lose while a tiny minority takes the profits, and she recommends banning them. She cites election betting's Tammany Hall roots, George Santos's $18,000 State of the Union wager, Donald Trump Jr's advisory role at Kalshi, growing fraud investigations, and warns the platforms' valuations may be a bubble under a Trump-friendly regulator.
