Focusing on online brand communities (OBCs) centered around K-pop music consumption, this study explores the influential role of women as peer-leaders. By analyzing data from Twitter using social network analysis (SNA) and sentiment analysis techniques, we observe that (1) OBCs naturally form transnational consumer segments, (2) where peer leadership emerges organically, and (3) women often occupy these leadership positions due to their social capital and engagement in relevant conversation topics. This study contributes to demonstrating the increasing empowerment of women in a realm that has long been criticized for its portrayal of gender-related issues.
