**Therese Terlaje and Vicente Ada advanced as the major-party nominees after the August 1, 2026 primaries for Guam’s November 3 general election.** Terlaje defeated incumbent Lt. Gov. Joshua Tenorio by a narrow 47.8%–44.4% margin in the Democratic primary, while Ada secured the Republican nomination with a stronger 60.5%–39.3% victory over Speaker Frank Blas Jr. Guam’s term-limited Democratic governor is not on the ballot, leaving an open race between the two territorial senators and their running mates. Trader pricing reflects Terlaje’s edge at 67.5% versus Ada’s 32.5%, consistent with the Democratic Party’s recent performance in island-wide contests and the absence of major late-breaking shifts since the primaries. A late-August candidate forum highlighted shared priorities on economic development, childcare costs, and public health, but produced no decisive polling movement. The two-candidate general-election structure and roughly two-month timeline to Election Day leave room for standard campaign dynamics, turnout patterns in key villages, and any emerging issue salience to influence final margins.
