Greetings All,

We are delighted to announce SemEval-2026 Task 9: Detecting Multilingual, Multicultural, and Multievent Online Polarization.

Polarization refers to the sharp division of opinions into opposing groups, often accompanied by hostility and exclusion. This shared task aims to advance our understanding of how polarization manifests in text across languages, cultures, and events. Participants will develop systems to detect and interpret polarized content in contexts such as elections, conflicts, protests, and debates.
