Congressional Prediction Market Ban Act of 2026

Ban on Congressional Prediction Trading

If enacted, Members of Congress would be banned from buying, selling, or benefiting from prediction-market contracts. A prediction-market contract would mean a trade tied to a specific event that involves an excluded commodity; it would not include ordinary insurance. A Member would also be treated as benefitting if a household member's trade resulted in a payment to the Member or another household member. Each Member would have to certify, within 15 days after the start of each year, that they complied with the ban for the prior calendar year, and those certifications would be posted on the Clerk or Secretary public websites. Congressional ethics committees would publish compliance procedures and guidance within 90 days and Members would have to comply within 180 days. Committees would investigate missed certifications or credible reports of violations. A Member found to have violated the rule would face a fine equal to the greater of $10,000 or three times the profit made; fine amounts would be deposited in the Treasury. Committees could pursue other sanctions under chamber rules.
