As of November 5, 2025, two statewide ballot measures were certified to appear on the Missouri ballot in 2018.

Getting measures on the ballot

Citizens of Missouri may initiate legislation as either a state statute or a constitutional amendment. In Missouri, citizens also have the power to repeal legislation via veto referendum. The Missouri General Assembly may also place measures on the ballot as legislatively referred constitutional amendments or legislatively referred state statutes with a majority vote.

In 2018, citizens were required to file at least 100,126 valid signatures for initiated state statutes and veto referendums, and they were required to file at least 160,199 valid signatures for initiated constitutional amendments. These signature requirements are the requirement if petitioners collect signatures in the smallest of the state's congressional districts to satisfy the state's distribution requirement. Collecting signatures in larger districts would result in a slightly larger signature requirement.

The 2018 state legislative session ran from January 3, 2018, to May 18, 2018, during which time the Missouri State Legislature was able to place legislative referrals on the ballot.
