Incumbent Governor Ademola Adeleke of the Accord Party holds the leading position in the Osun State gubernatorial election scheduled for August 15, 2026, with traders assigning him a 60.5% implied probability. His advantage stems from incumbency, ongoing campaign efforts including direct appeals in rival strongholds such as the hometown of APC candidate Bola Oyebamiji, and assessments that opposition figures lack comparable organizational strength. Oyebamiji sits at 27.5%, while smaller shares are assigned to Saliu Oyelami and others. Recent weeks have featured heightened political activity, mutual allegations of violence and governance shortcomings between the Accord and APC camps, and court-related disputes over party structures, all of which have reinforced trader focus on Adeleke’s structural position ahead of voting.
