Jorginho Mello (PL), the incumbent governor of Santa Catarina, holds a commanding lead in the October 4, 2026, first-round gubernatorial election, with recent polls showing him near or above 50% of intended votes against a fragmented field. His position stems from strong approval ratings near 70%, a broad coalition including Novo and other parties, and consistent leads of 25–30 points or more over the nearest challenger, João Rodrigues (PSD). The state’s conservative electorate and Mello’s focus on infrastructure, education, and security have reinforced trader consensus around his reelection. A first-round victory would resolve the market outright, while a runoff on October 25 would require the opposition to consolidate support behind one candidate. Late shifts could occur from turnout surprises or major campaign developments, though current evidence points to limited risk of such changes.
