Therese Terlaje (D) leads the Guam gubernatorial race at 66.5% implied probability, ahead of Vicente Ada (R) at 32.5%, reflecting her stronger position entering the November 3, 2026, general election. Terlaje secured the Democratic nomination in the August 1 primary with 47.8% against Lt. Gov. Josh Tenorio, while Ada won the Republican primary by a wider 60.5% margin. Recent October forums and early voting, which opened on October 8, have kept focus on shared priorities such as permitting reform, healthcare access, housing, and economic development tied to military buildup. As an open-seat contest with no incumbent, the race remains sensitive to turnout among key voting blocs and any late shifts in voter sentiment before election day.
