Incumbent Jorginho Mello holds the leading position in the Santa Catarina governor race, backed by consistent polling advantages and his established record since taking office in 2023. Multiple pre-candidates from parties including PSD, PT, Novo, and PSOL have entered the contest ahead of official conventions in August and the October 4 first round, creating a fragmented field that sustains separate contract pricing across outcomes. Recent surveys from May show Mello ahead by wide margins in head-to-head and multi-candidate scenarios, yet the spread of trader prices across names indicates uncertainty over coalition alignments, voter turnout in key regions, and potential runoff dynamics. Scheduled party negotiations and any shifts in approval ratings could alter positioning before the campaign period begins.
