This thesis examines the responses of incumbents to the emergence of new categories facilitated by digital platforms. As a new form of organization, digital platforms mediate interactions between producers and audiences, thus influencing how offerings are perceived and valued. As they emerge in most sectors, digital platforms often challenge incumbents and the categories to which they belong. However, existing research is limited in capturing the impact of digital platforms on the categorization process and existing categories. Moreover, we lack an understanding of how incumbents resist or adapt to these exogenous changes in categorical systems. The first essay of this thesis proposes a theoretical model that shows how digital platforms promote the emergence of new categories and influence the evolution of existing ones. Empirically, I study how incumbents respond strategically to the emergence of platform banking in the European banking sector over the decade 2013-2023. The second essay argues that category emergence is not only a threat, but also an opportunity for incumbents to create new categories that allow them to achieve a balance of optimal distinctiveness. The third essay shows how incumbents simultaneously promote category creation and emphasize their distinctiveness through parallel identity claims. This thesis contributes to the literatures on category dynamics and optimal distinctiveness.
