Missouri voters face Amendment 3 on the November 3, 2026 ballot, a legislatively referred measure that would repeal the 2024 Right to Reproductive Freedom Amendment protecting abortion access through viability while imposing strict limits on the procedure and placing a permanent constitutional prohibition on gender transition procedures for minors. The latter restrictions largely mirror an existing statutory ban upheld by the state Supreme Court in January 2026 and set to expire in 2027. Recent 2026 court rulings have already restored medication abortion and struck down several prior limits following the 2024 amendment’s implementation. Traders assign the measure only a 31.5% chance of passage, reflecting the 2024 electorate’s approval of broader reproductive rights, successful litigation expanding access this year, and the political difficulty of repealing a voter-approved constitutional provision even when paired with the minors’ care restriction.
