Morena holds a commanding position in the Colima Congress election market at 71% implied probability, reflecting its status as the largest bloc with 11 of 25 current seats and sustained polling strength in the state ahead of the June 2027 vote. The party benefits from national momentum following federal legislative gains and a leading position in concurrent Colima governor surveys, even as the opposition remains fragmented. PVEM’s decision to compete independently after ending its prior alliance has lowered its odds to 6.5%, while PT, MC, PRI, and PAN trail further behind. Traders price these outcomes based on the state’s first-past-the-post and proportional representation system, with limited recent events altering the frontrunner dynamic since the alliance split earlier in 2026.
