Missouri will not be using its newer 2025 congressional map in the 2026 election. In a brief, unsigned order issued Friday, the U.S. Supreme Court directed the state to run the 2026 congressional election under the boundaries from Missouri’s 2022 map instead.
For everyday voters, the practical takeaway is simple: whatever district lines Missouri used most recently under the 2022 map are the lines that will govern the 2026 U.S. House races.

What the Supreme Court ordered
The Court’s order does two things at once, which is part of why it matters.
- First, it blocks courts from stopping Missouri’s 2022 map from being used in 2026.
- Second, it blocks courts from forcing Missouri to use the newer 2025 map in 2026.
The order states: The District Court and Court of Appeals should not enjoin or otherwise prohibit the use of the 2022 map in the 2026 congressional election in Missouri.
And it adds: And the District Court and Court of Appeals should not order or otherwise require Missouri to use the 2025 map in the 2026 congressional election in Missouri.
Why this is unusual
Redistricting fights often ask courts to pick one set of lines over another. Here, the Supreme Court’s message was more procedural and stabilizing: lower courts should not whipsaw the state between competing maps as the 2026 election approaches.
Instead of letting the dispute keep ricocheting through emergency litigation, the Court effectively pressed pause and directed that the older, already in place 2022 boundaries remain the rules for 2026.
What it means for 2026 races
The ruling ends the immediate scramble over which map will govern the 2026 midterms in Missouri. Candidates, election administrators, and voters can plan around a known set of district lines instead of waiting to see whether a late court ruling reshapes the playing field.
Separately from the Court’s procedural language, the political stakes have been part of the backdrop: the newer 2025 map was seen as potentially helping Republicans in the upcoming midterm elections. By keeping the 2022 map for 2026, the Court is keeping the status quo in place for one more cycle.
Quick civics context
Under the Constitution, states take the lead on drawing congressional districts, typically through the state legislature and the normal lawmaking process. But federal courts can step in when map fights raise federal legal questions, and state courts can be involved when state constitutional rules are at issue.
When disputes become time-sensitive, the Supreme Court sometimes issues short emergency orders like this one. These orders are often designed to prevent last-minute rule changes that could disrupt elections, even while broader legal questions continue to be argued elsewhere.
Common questions
Does this change my district right now?
No. The order is about what will be used for the 2026 election. It directs Missouri to use the 2022 map for that cycle.
Did any justice dissent?
The order was unsigned and drew no noted dissents.
Is Missouri barred from ever using the 2025 map?
The order is specifically aimed at the 2026 congressional election. It blocks lower courts from requiring use of the 2025 map for 2026 and blocks them from preventing use of the 2022 map for 2026. It does not, by itself, answer every possible question about later election cycles.
