This bill aims to prevent Members of Congress, their spouses, and dependent children from profiting through prediction markets. It specifically restricts these covered individuals from entering into agreements or transactions dependent on the occurrence or non-occurrence of specific government policies, government actions, or political outcomes. The prohibition also extends to events that come to their attention due to a Member's congressional service, regardless of its connection to official duties. Violations of these restrictions will result in a fee, calculated as the greater of $2,000 or ten percent of the transaction's value, plus any net gain realized from the prohibited activity. These fees cannot be paid from official allowances like the Members' Representational Allowance or campaign contributions. The supervising ethics office is tasked with directing the imposition of these penalties, issuing interpretive guidance, and may refer former Members who fail to pay fees to the Department of Justice.
