Sen. Elizabeth Warren to crack down on prediction markets as Senate Banking chair
Senator Elizabeth Warren plans to increase oversight of prediction markets after becoming chair of the Senate Banking Committee in January. A banking aide told Punchbowl News that Warren will use the committee’s investigative powers to address insider trading and manipulation on platforms such as Kalshi and Polymarket. The move follows a letter she and Sen. John Curtis sent to the two companies requesting information on how they prevent candidates and campaign staff from trading election contracts. The senators asked for written responses by Election Day, Nov. 3.
