Iliana Iotova leads the Bulgaria presidential election market at 73.5% as the incumbent acting president, backed by the ruling Progressive Bulgaria party and the Bulgarian Socialist Party following her August confirmation of candidacy and endorsements. Her position stems from roughly 50% public approval ratings in recent surveys, the parliamentary majority secured by her aligned coalition in the April 2026 vote, and the absence of major challengers able to consolidate opposition support ahead of the October 25 first round. Andrey Gyurov trails at 19.5% amid fragmented fields that include smaller shares for figures such as Nikolai Denkov and Vassil Terziev. Trader pricing reflects these structural advantages for the incumbent in a system where the frontrunner typically advances decisively, though late campaign dynamics or turnout shifts could still influence the outcome.
