Morena leads the Hidalgo Congress election market at 67.5% implied probability, reflecting its control of the state governorship and strong performance in recent local contests. Traders price the outcome ahead of the June 2027 vote, where the 30-seat legislature will be renewed under rules recently harmonized by the state Congress with federal constitutional requirements. Ongoing alliance discussions between Morena and parties such as Nueva Alianza Hidalgo, PVEM, and PRD, alongside PT signals of possible independent participation, shape positioning for majority or qualified-majority control. Opposition parties including PAN at 13.5% and PRI at 4.1% trail due to narrower bases in the state, while the June 6, 2027, election date and coalition registration windows beginning December 2026 remain the primary near-term catalysts.
