The 2027 Mexican legislative election for the Chamber of Deputies remains more than a year away, yet trader odds reflect a tight contest for second place among several smaller parties behind the expected Morena-led coalition finish. PT leads narrowly at 49 percent implied probability, followed closely by MC at 44.5 percent and PRI, PAN, and PVEM clustered near 41 percent, while Morena sits at just 2.3 percent. This positioning stems from the ruling coalition’s dominant structural position after 2024, tempered by the March 2026 defeat of President Sheinbaum’s electoral reform bill, which fractured support even from PT and PVEM partners concerned about seat losses and reduced public funding. Opposition parties including PAN, PRI, and MC continue early organizational efforts to consolidate anti-incumbent votes, while internal coalition frictions and the absence of major new polling shifts keep the second-place outcome highly competitive and sensitive to future alliance adjustments or candidate selection rules.
