This work introduces the concept of adjudication to define the act of granting or denying ownership of an outcome to individuals or groups in social media. We extend existing models of political dialogue to explain differences between winners and losers when elections are adjudicated. We use Twitter data on three elections in Argentina, Brazil, and the United States. We show an increase inevent salience upon adjudication, followed by more extensive dialogue among winners and disengagement among losers. Further, we show differences in the network structure of dialogue, with dialogue in winning communities being less hierarchical and dialogue in losing communities being more hierarchical.
