Therese Terlaje holds the leading position in trader consensus for the Guam Democratic primary on August 1, 2026, reflecting her extended service as a territorial senator and former legislative speaker, which has delivered broad name recognition across the electorate. Josh Tenorio, the current lieutenant governor who launched his bid earliest with a sitting running mate, remains the primary challenger but trails in market pricing. Joe S. San Agustin registers negligible support as a distant third. Recent University of Guam polling from early June showed the top two Democratic teams nearly tied, yet subsequent market movement toward Terlaje aligns with her established legislative profile and late-campaign dynamics in a race without an incumbent governor. Primary results will determine the Democratic ticket for the November general election.
