A crowded field of more than two dozen candidates keeps the Lima mayoral race highly competitive, with no single contender exceeding 27% implied probability in current trader pricing. Carlos Bruce leads at 26.5%, followed closely by Francis Allison at 23% and Luis Rubio at 22.5%, while Daniel Urresti sits at 12.5% and remaining options trail below 10%. This fragmentation reflects Peru's multiparty municipal system, where vote splitting among independents and smaller parties sustains uncertainty ahead of the October vote. Key variables that could shift probabilities include party endorsements, late campaign momentum in key districts, turnout patterns among urban voters, and any scandals or alliances that consolidate support behind one of the top three.
