With boom in prediction markets, some lawmakers worry about how to police themselves

House and Senate ethics committees currently provide no financial disclosure guidance for lawmakers trading on prediction markets or event contracts, despite requiring disclosure for stocks, cryptocurrency, and bond trades. The regulatory gap comes as prediction markets experience rapid growth, creating uncertainty about whether congressional members must report these types of investments. This oversight leaves lawmakers without clear rules on whether they need to disclose bets on political outcomes or other events, potentially creating ethics blind spots. The lack of guidance raises questions about transparency and potential conflicts of interest as more members of Congress may participate in these emerging financial instruments.
