Idaho’s position
Idaho’s constitution declares that “gambling is contrary to public policy and is strictly prohibited,” allowing only the state lottery, pari-mutuel betting and charitable bingo and raffles. There’s no legal sports betting.
In March 2026 Attorney General Raúl Labrador joined a multistate brief backing Nevada against Kalshi and Crypto.com in the Ninth Circuit, warning that “States like Idaho that choose to ban sports betting would be prevented from enforcing those bans under the CFTC’s theory.” He added: “Idaho will continue defending our right to regulate gambling.” Idaho also signed the October 2026 states’ brief at the US Supreme Court.
