Campaign announcements, candidate withdrawals, or coalition shifts could alter the competitive landscape. Economic data, inflation trends, or policy announcements by the current government may influence voter sentiment. Debates and media coverage often trigger repricing as traders reassess candidate momentum. International events or domestic crises could reshape electoral dynamics. Additionally, campaign spending reports and voter registration changes provide signals about candidate strength and organizational capacity heading into the first round.
