Incumbent President Iliana Iotova holds an 86% market-implied probability in the October 25 Bulgarian presidential election due to her strong polling lead of 41–52% among decided voters in late September and early October surveys, backed by the Bulgarian Socialist Party and support from Rumen Radev’s Progressive Bulgaria coalition. Her nomination committee, formed in September with broad backing from political figures, intellectuals, and institutions, and her status as the first woman to hold the office after succeeding Radev in January 2026, reinforce trader consensus on her frontrunner position. Andrey Gyurov, the main challenger at 13.5% with 22–28% polling support, trails as a former caretaker prime minister but lacks comparable institutional momentum. Other registered candidates remain fragmented below 10% in polls, with negligible market pricing reflecting limited viability in the two-round system.
