Incumbent Jerônimo Rodrigues (PT) holds a clear edge in trader pricing for the October 4 first-round vote, reflecting Bahia’s long-running PT dominance since 2006 and his position as the sitting governor seeking reelection against the same main rival he defeated in 2022. ACM Neto (União Brasil), the former Salvador mayor and opposition standard-bearer, trails in the implied probability despite strong name recognition and consistent polling near or occasionally ahead of Rodrigues in first-round and runoff simulations through mid-September. Minor candidates remain negligible, consistent with their single-digit or sub-1% survey shares. Late-August and early-September polls from institutes such as Real Time Big Data and others showed the two frontrunners in technical ties or narrow swings within margins of error, while official campaign activity began in mid-August and candidate slates were finalized by early that month. Traders appear to weigh incumbency, state-level PT infrastructure, and the absence of decisive late momentum shifts for the challenger as the primary factors sustaining the current pricing gap.
