A legislative election is scheduled to be held in Mexico on June 6, 2027. This market will resolve according to the political party that wins the second greatest number of seats in the Mexican Chamber of Deputies (Cámara de Diputados) as a result of this election. If the results of this election are not known definitively by March 31, 2028, 11:59 PM ET, this market will resolve to "Other". The named parties or coalitions will be primarily ranked by the number of seats won in the specified election. If two or more parties are tied on seats, ties will be broken by the total number of valid votes received, with higher vote totals ranking higher. If parties remain tied, ties will be broken by alphabetical order of the listed party abbreviations. This market will resolve to the party that occupies the second finishing position after applying this ranking. This market's resolution will be based solely on the number of seats won by the named party in the Mexican Chamber of Deputies. This market will resolve based on the results of this election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results reported by the Mexican Government, specifically the National Electoral Institute (https://ine.mx/).
Polls for Mexico's June 2027 legislative elections consistently place Morena first in Chamber of Deputies voting intention, followed by PAN in second at roughly double the support of PRI or MC. Trader consensus on PAN for second place reflects this sustained gap, the opposition's decision to compete separately after the PAN ended its prior alliance with the PRI, and limited recent shifts in national surveys. High presidential approval for the Morena-led government has not altered the relative ordering among challengers, while undecided voters and potential state-level dynamics remain secondary to the national preference pattern.
