Contact Congress about S. 4017: End Prediction Market Corruption Act

Top federal officials would face new limits on trading event contracts, which are bets on future events. Some officials would be banned from these trades, and others would have to report them.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

End Prediction Market Corruption Act is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Agriculture, Nutrition, and Forestry.

Latest action on S. 4017: Read twice and referred to the Committee on Agriculture, Nutrition, and Forestry.

Who this affects: This bill mainly affects top federal officials and their families. It also affects foreign trading platforms that offer event contracts through U.S. commerce. The CFTC and the Attorney General would get new duties to police these trades.

Why this matters: This bill matters because top officials may know or shape events that people can bet on in prediction markets. The bill tries to reduce conflicts of interest and make these trades easier to see. It could also limit how some officials and their families invest. The full effect on prediction markets is not clear from the text.

Key provisions in S. 4017

  • The President, Vice President, and members of Congress could not trade any event contracts. That means they could not buy, sell, or otherwise exchange these bets on future events.
  • Senior executive branch officials would face a narrower ban. They could not trade event contracts tied to matters they personally and substantially handle in their government work.
  • The Attorney General could sue people who break the trading bans. Those lawsuits would go to federal court.
  • Violators could face a civil fine. The fine could be up to $10,000 for each violation or the profit from the bad trade, whichever is larger.
  • The bill would not make civil fines the only consequence. Other criminal, civil, or agency penalties could still apply.
