Prior work has focused on understanding coopetition tensions and response in bilateral coopetitions. Even though multilateral coopetitions are prevalent in practice they have not been fully studied in terms of coopetition tensions and their management. This omission is problematic. Multilateral coopetitions can complement what we know in prior work because they are inherently complex with multiple actors and greater coordination needs. Hence, we asked: how are tensions experienced and managed in multilateral coopetitions? We answer this question by drawing on 31 interviews and archival data from seven multilateral coopetitions. We found three types of multilateral coopetitions comprising member companies and independent central coordinating organization. We show that actors within each coopetition type experience tensions differently and have varied capabilities to manage these tensions. Our contribution is twofold. First, we complement insights from prior work by opening the black box of coopetition tensions to show that not all coopetition tensions are salient for actors within and across coopetitions. Second, unlike prior work that locates capabilities within focal firms, we show that coopetition capabilities are dispersed across actors, which has implications for value creation and capture.
