Idaho voters will decide Proposition 1, the Reproductive Freedom and Privacy Act Initiative, on November 3, 2026. The citizen-initiated statute, which qualified for the ballot in July after organizers collected more than 100,000 signatures across legislative districts, would establish a right to reproductive freedom and privacy, permitting abortion up to fetal viability with exceptions for medical emergencies while protecting access to contraception, fertility treatments, and related care. Current Idaho law imposes one of the nation’s strictest bans with narrow exceptions only. Recent litigation over ballot language concluded with Idaho Supreme Court-approved revisions in early September, clearing the path for the vote. In a state where Republicans control the legislature and governor’s office, traders price the measure near even odds, reflecting broad signature support including from some Republican voters alongside organized opposition and the measure’s statutory rather than constitutional status.
