Voters in Michigan will decide the automatic constitutional convention question on the November 2026 ballot, which appears every 16 years under the 1963 constitution. Trader consensus heavily favors rejection at over 95 percent, consistent with prior outcomes where similar measures failed by wide margins of 67 to 77 percent. Limited organized support for convening delegates, combined with the absence of major recent catalysts such as widespread public dissatisfaction or high-profile reform campaigns, has kept implied probabilities stable. Potential shifts could still arise from late-cycle developments, including targeted ballot initiatives on term limits or redistricting that heighten attention to constitutional changes, or unexpected endorsements from major political figures or interest groups ahead of the general election.
