Therese Terlaje holds the strongest position among the three candidates in Guam’s Democratic primary for governor, scheduled for August 1, 2026, due to her extensive legislative record and prior service as speaker of the Guam Legislature. Josh Tenorio, the sitting lieutenant governor with broad name recognition from his current role, trails in trader assessments, while territorial senator Joe S. San Agustin registers as a more distant contender following recent filings that confirmed the three-way field. With no public polling available and the race open after the incumbent governor reached term limits, market pricing reflects traders’ emphasis on established institutional experience and early organizational signals over other factors. Campaign activity through the summer primary window could still alter relative standings.
