Public Integrity in Financial Prediction Markets Act of 2026 is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on Homeland Security and Governmental Affairs.
Latest action on S. 4188: Read twice and referred to the Committee on Homeland Security and Governmental Affairs.
Who this affects: This bill mainly affects federal officials and staff who trade in prediction markets. It also affects ethics offices, because they would have to build the reporting system and enforce the new rules. Prediction market platforms may also feel the effects because officials would have to report trades made on those platforms, even if the platform is outside the United States.
Why this matters: Prediction markets create a real conflict risk when officials know things the public does not. A federal official may learn about coming government actions before everyone else. This bill tries to stop officials from turning that inside knowledge into personal profit. It also gives ethics offices trade reports they can use to check for problems.
