Armed in ARMY: A Case Study of How BTS Fans Successfully Collaborated to #MatchAMillion for Black Lives Matter

Music fans strategically support their artists. Their collective efforts can extend to social causes as well: In 2020 for example, ARMY—the fandom of the music group BTS—successfully organized the #MatchAMillion campaign to raise over one million USD to support Black Lives Matter. To better understand factors of fandoms’ collaborative success for arguably unrelated social goals, we conducted a survey focusing on ARMYs’ perceptions of their fandom and their social effort. Most ARMYs viewed the fandom as a community, loosely structured with pillar accounts. They reported trust in each other as well as high team composition, which mediated the relationship between their neutral psychological safety and high efficacy. Respondents attributed their success in #MatchAMillion to shared values, good teamwork, and established infrastructure. Our findings elucidate contextual factors that contribute to ARMY’s collaborative success and highlight themes that may be applied to studying other fandoms and their collaborative efforts.
