The 2026 elections in Piauí already have a significant number of registered electoral polls. In total, 130 surveys have been filed with the competent authorities, demonstrating the interest of candidates and parties in measuring the preference of the Piaui electorate.
The majority of these polls focus primarily on the Senate race. The senator position appears as the most explored theme by research institutes in the state, possibly due to the political relevance and visibility that the Senate seat represents in the local political landscape.
The numbers revealed by the Superior Electoral Court indicate that the registered surveys predict a total of 89,586 interviews with Piaui voters. This significant volume of interviews reflects the size of the investment being made to understand electoral behavior in the state.
In financial terms, the amounts reported for conducting these polls total R$ 3,023,351.63. This amount represents the cost declared by the institutes for executing the surveys that will guide the electoral campaign strategies in Piauí during the 2026 cycle.
