Therese Terlaje, the Democratic nominee and former legislative speaker, holds the leading position in the November 3, 2026, Guam gubernatorial contest against Republican Vicente Ada, consistent with trader pricing that reflects her narrow August primary victory over the sitting lieutenant governor and Guam's pattern of Democratic success in recent executive races. Both candidates advanced from competitive primaries, with Ada securing a clearer Republican win, and recent candidate forums have focused on shared priorities such as economic development, healthcare access, and military buildup impacts without major shifts in positioning. Early voting has begun, leaving limited time for late developments to alter the implied probabilities before ballots are cast.
