This study investigates how proponents and critics of gene editing in agriculture and food (GEAF) employ expectations-discourses with future-oriented impacts-as they compete to secure desired futures and mobilise social processes and resources towards their goal of influencing GEAF (re)regulation and agro-food systems within the EU. We draw on 27 semi-structured interviews and 53 Euractiv media articles to identify and analyse GEAF proponents' and critics' responses to the 2018 European Court of Justice regulatory decision that GEAF will be regulated as genetically modified organisms.
