Recent polling in Mato Grosso do Sul shows Flávio Bolsonaro (PL) maintaining a commanding lead over incumbent President Lula (PT) ahead of the October 2026 presidential election, with first-round estimates ranging from 40-57% for the senator versus 25-33% for Lula across multiple surveys conducted in September. The state's agricultural economy and conservative voter base have contributed to consistent double-digit advantages for the PL candidate in both first- and second-round simulations, where he often reaches 51-52%. Trader consensus reflected in current pricing aligns with these patterns and the state's historical electoral trends. Late shifts in turnout, national campaign developments, or unexpected first-round results could still alter the second-round dynamic in this battleground state.
