The Supreme Court decided that the 2025 Missouri congressional map will not take effect for the 2026 election cycle.

What we found

Supports. The Supreme Court's unsigned opinion states that the 2022 map, not the 2025 map, must be used in the 2026 congressional election in Missouri, and that lower courts should not order use of the 2025 map.[3][6]

Supports. AP and CBS report the Supreme Court on September 25, 2026 again blocked the Trump-backed 2025 map, clearing the way for use of the 2022 district lines in the November election.[1][4]

Supports. The Missouri Supreme Court had earlier ruled the 2025 map cannot take effect unless voters approve it in a referendum, and the U.S. Supreme Court let that ruling stand.[1][5][7]

Context. The 2025 map was used in the August 4 primary, but the 2022 map governs the November general election; the post's 'this election cycle' and 2022 version wording matches this outcome.[2][8]
