**Recent polling for Brazil’s October 4, 2026, presidential first round shows a fragmented field that makes an outright majority (over 50% of valid votes) highly unlikely.** Incumbent Luiz Inácio Lula da Silva (PT) leads with 38–41% support across late-August surveys from Datafolha, Nexus/BTG, PoderData, Indexa, and others, while Flávio Bolsonaro (PL) trails at 33–37%. Minor candidates including Ronaldo Caiado (PSD), Renan Santos (Missão), Romeu Zema (Novo), and others remain in the low single digits, splitting opposition votes. Combined support for the two frontrunners typically totals 72–78%, leaving substantial shares for undecided voters, null/blank ballots, and smaller contenders. This distribution aligns with Brazil’s multi-party system and unbroken pattern of runoffs in every presidential election since 2002. The official campaign opened August 16, with free electoral broadcasts beginning August 28 and the first debate held August 23; no recent consolidation or surge has pushed any candidate near the absolute-majority threshold. Second-round simulations remain tight (often statistical ties), reinforcing expectations of a runoff on October 25. Traders price the “No” outcome at 91% to reflect these persistent structural and polling realities.
