Two US Senators Introduce Legislation to Regulate Prediction Market Trading
US Senators Jeff Merkley and Amy Klobuchar are set to introduce legislation on Thursday that would bar members of Congress, the president, and vice president from trading event contracts on prediction market platforms like Kalshi and Polymarket. The bill aims to curb potential misconduct by lawmakers and other government officials who may use confidential information for financial gain.
The proposed legislation would also apply to other members of the executive branch, imposing fines of at least $10,000 for each violation. In addition, violators would be required to pay back profits made in trades. The move comes amid growing concerns about the integrity of prediction markets, which have seen significant growth in recent years.
Prediction markets allow users to make wagers on future events, including election outcomes and monetary policy decisions. However, some users have profited from positions that were later proven correct, raising questions about the use of confidential information by government officials.
Kalshi, a fully regulated exchange in the US, has expressed support for the legislation, stating that it would help to ensure market integrity. Polymarket, on the other hand, remains unregulated and has faced criticism for its lack of oversight.
The introduction of this legislation follows similar efforts by other lawmakers, including Senator Chris Murphy, who is working on separate legislation to curb the industry. A conservative coalition, led by former White House Office of Management and Budget director Mick Mulvaney, also wants to regulate prediction markets more closely, drawing parallels with sports betting.
