PredictIt is an online political futures market in which users purchase shares relating to the outcome of political events using real money.

Services such as PredictIt can be used to gain insight into the outcome of elections.

On May 10, 2024, the Commodity Futures Trading Commission (CFTC) voted 3-2 to issue a rule proposal that would ban election betting markets. Previously, the commission announced it intended to rescind PredictIt’s no-action letter on August 4, 2022, with an effective date set for February 2023. On its website, PredictIt said that barring any changes in CFTC policy, it would halt trading on February 15, 2023. The CFTC reversed this decision in March 2023, allowing the platform to operate legally.
