This prediction market asks which political party will win the Montana gubernatorial election in 2028 and have its candidate inaugurated as governor. Montana holds its gubernatorial elections every four years, with the next scheduled for November 7, 2028. The governor of Montana serves a four-year term, with no term limits since a 1992 ballot initiative removed them. The current governor, Greg Gianforte (Republican), was first elected in 2020 and reelected in 2024. He is term-limited from seeking a third consecutive term in 2028, meaning the race will be an open seat contest. Montana has trended strongly Republican in recent decades. The state has not elected a Democratic governor since Brian Schweitzer, who served from 2005 to 2013. Since then, Republicans have held the office: Steve Bullock (a Democrat) was term-limited and succeeded by Gianforte. Republicans currently hold supermajorities in both chambers of the Montana Legislature. The state's presidential voting pattern has also shifted rightward. Donald Trump won Montana by 16.4 points in 2020 and by 19.4 points in 2024. However, Montana has a history of electing Democrats to statewide office, particularly in gubernatorial races. Between 1972 and 2020, the state elected five Democratic governors and three Republicans. The 2028 race will test whether that tradition can reemerge or if the GOP's dominance solidifies. Key issues likely to shape the contest include public lands management, property tax reform, housing affordability, and education funding. Montana's population has grown faster than the national average, driven by in-migration from states like California and Washington. This demographic shift could alter the electorate's composition. Candidates from both parties are expected to begin formal campaigns by early 2027. The primary elections will take place in June 2028. The general election will be decided by a plurality vote, with no runoff system. Third-party candidates have rarely exceeded 5 percent of the vote in recent gubernatorial races.

Historical Context

Montana's gubernatorial elections have been competitive for much of the state's history. From statehood in 1889 through 2024, the governorship has been held by Republicans for 84 years and Democrats for 56 years. The state elected its first Democratic governor in the 20th century, Joseph M. Dixon, in 1920. The longest-serving governor was Democrat John W. Bonner (1949-1953) and Republican Marc Racicot (1993-2001), each serving two terms. The 1992 term limits ballot initiative, passed by voters with 67 percent support, limited governors to two consecutive terms. This law was later overturned by the Montana Supreme Court in 2004, but the legislature reinstated term limits in 2012 through a constitutional amendment. Since then, no governor has served more than eight consecutive years. The 2004 election saw Democrat Brian Schweitzer defeat Republican Bob Brown with 50.4 percent of the vote. Schweitzer's victory was attributed to his appeal to rural voters and his focus on energy independence. He was reelected in 2008 with 65.5 percent, the largest margin for a Montana governor since 1968. His successor, Democrat Steve Bullock, won in 2012 with 48.9 percent and was reelected in 2016 with 50.2 percent. Bullock's narrow win in 2016 came despite Trump winning the state by 20 points. This split-ticket voting pattern shows Montana voters' willingness to separate state and federal elections. The 2020 election saw Greg Gianforte defeat Democrat Mike Cooney with 54.4 percent. Gianforte's win marked the first time since 2000 that a Republican succeeded another Republican in the governor's office. The 2024 election saw Gianforte win reelection with 58.7 percent, the highest for a Republican since 1968.
