Trust has been acknowledged as an important aspect of interorganizational relationships. Yet, limited attention has been paid to the importance of trust in the light of coopetitive interactions, i.e. simultaneously cooperating and competing. Research on trust has started to acknowledge that more trust may not always be better, and that trust and distrust are separate and distinct phenomena. Whilst coopetition research has mentioned the important role of trust, the potential role of distrust is even less acknowledged, although it may be particularly relevant due to the tensions, risks, and uncertainties involved. The purpose of this paper is to identify limitations and gaps in the extant literature on trust in coopetition, bring promising research opportunities into light, and create an agenda for future research focused on the roles of both trust and distrust in coopetition. By means of a systematic literature review, we find that the importance of trust in different phases of coopetition has been acknowledged by prior research, yet deeper explanations of how, when, and why different aspects of trust and distrust matter to coopetition are missing. A normative view on trust prevails and the potential fruitfulness of distrust is neglected. Based on these limitations, an agenda including six promising research avenues is constructed.
