Overview
- Prediction markets let people buy and trade financial contracts that pay out based on events such as vote totals or winners, and federal action since 2024 has treated many election contracts as regulated products rather than gambling.
- More than half of U.S. states now restrict or ban election betting, with rules that vary from misdemeanor fines to felony charges or even voter-rights penalties, according to recent Pew and state-law reviews.
- In May, Minnesota enacted a sweeping ban on platforms like Kalshi and Polymarket and the CFTC sued to block the law, continuing a legal clash that follows a federal injunction that paused Arizona’s criminal case against Kalshi in April.
- State election officials say they will pursue enforcement against illegal wagers and refer cases to prosecutors when civil tools fall short, but they warn practical hurdles such as anonymous accounts and cross-border trading will complicate prosecutions.
- Lawmakers in Congress have proposed federal bans and platform advocates argue markets improve forecasting, leaving courts and policymakers to weigh risks of manipulation and erosion of public trust against claimed forecasting benefits.
