Michigan voters will decide Proposal 1 on the November 2026 ballot, an automatically recurring question every 16 years under the state constitution that asks whether to convene a constitutional convention in 2027. Delegates elected by district would then draft a full revision of the 1963 document for later voter approval. The measure last appeared in 2010 and was rejected by roughly two-thirds of voters, consistent with prior cycles. No organized campaign has emerged with significant momentum to secure majority support, and competing citizen-initiated proposals have faced certification hurdles, including recent Board of State Canvassers deadlocks over signature validity. Trader consensus at 93% for rejection reflects this historical pattern and absence of new developments shifting the baseline likelihood of approval.
