Rastislav Trnka, the incumbent independent governor of Košice Region since 2017, leads the October 24, 2026, election market at 61.5% implied probability due to consistent polling leads of 47–53% in surveys from earlier in the year and his established record of regional development projects. Marián Porvažník, backed by a broad opposition coalition including Progresívne Slovensko, SaS, and others, sits at 30.5% as the main challenger, though unified support has not yet closed the gap in voter surveys. Igor Šimko, nominated by Hlas-SD with additional ruling-party backing, trails at 10.5%, reflecting limited crossover appeal. Trnka’s independent status and endorsements, such as from Maďarská aliancia, combined with recent legal vindication in a long-running dispute, reinforce trader consensus around his frontrunner position ahead of the joint communal and regional vote.
