Prediction Market Legal States

Prediction markets such as Kalshi are federally regulated by the CFTC as event-contract exchanges, so they're available in far more states than sportsbooks. Several states dispute whether sports event contracts are legal there, and court cases are ongoing, so availability can change quickly.

Age: 18+ on most exchanges; some apps or states require 21+
