Dates from INE's activities calendar for the 2026–27 process and the Constitution. INE may still move some by agreement; spans are inclusive.

Also on 6 June 2027 · local elections

17 governors,
19,609 local offices.

Local elections held the same day as a federal one use a single casilla for both (LGIPE art. 253.1), run with the state's electoral institute (OPLE). On 6 June 2027, 31 states also elect 1,098 local deputies and 18,057 municipal posts.

Current governor and party, 4 November 2026; governors are elected for six years and may not serve again.

Polls · encuestas · LGIPE art. 213

Three days,
then the western close.

“Durante los tres días previos a la elección y hasta la hora de cierre de las casillas, queda estrictamente prohibido publicar, difundir o dar a conocer […] los resultados de las encuestas o sondeos de opinión” (art. 213.2). Article 251.6 sets the end at the official close of the casillas “en las zonas de husos horarios más occidentales del territorio nacional”.

For 6 June 2027, that means from 3 June 2027 until 19:00 (Mexico City) on polling day (18:00 in Baja California, which keeps US summer time). Exit polls and private quick counts follow the same rule (Reglamento de Elecciones art. 134). Pollsters must notify INE and publish their method; publishing in the window is an electoral offence.

This site applies the rule in code (src/lib/mexico/rules.ts): inside the window this page prints no polls, the prediction-market panel shows no prices, and the results feed waits for the westernmost close.

Percentages as published. Most Mexican pollsters report raw intention with undecided voters in the base, so rows do not sum to 100 and houses are not directly comparable. All polls and approval →

Prediction markets · no link

Prices on prediction markets are what traders pay for contracts on an outcome; they are not polls or forecasts, and the people trading are not a sample of Mexican voters. Betting on elections has no permit from the Secretaría de Gobernación under the Ley Federal de Juegos y Sorteos, so prices are shown with attribution and no link to the market. They are withheld during the poll ban, like the polls.
