Republican Rep. Bryan Steil introduces legislation that would curb members of Congress from placing bets related to public policy outcomes on prediction markets. The proposal targets lawmakers’ ability to profit from such trading and is framed around preventing conflicts of interest as scrutiny grows around prediction platforms, including Kalshi and Polymarket. The bill would limit or bar congressional members and potentially their families from engaging in bets tied to government or political developments, aiming to reduce incentives that lawmakers could benefit from events they may influence.

The initiative arrives amid increasing public and regulatory attention on how prediction markets operate and whether they create risks of undue influence or insider advantages. Supporters argue that restrictions can help ensure policy decisions are not driven by financial exposure to market outcomes. The bill is presented as a direct response to concerns that lawmakers could benefit from wagering on political events or policy consequences. The details of how the ban would be enforced and what categories of bets would be covered are central to the bill’s potential impact.
