What is the relationship between parliamentarians and large agribusiness corporations in Brazil, and how do these actors influence the legislative process? This study investigates how major economic groups shape political decisions in the Brazilian Chamber of Deputies and what is at stake in these relationships. The research examines how socio-technical networks linking agrarian actors and politicians operate between 2015 and 2025, producing effects that can be interpreted as forms of state capture. The concept of state capture refers to the decisive influence of capital over state institutions and the ways in which corporations shape the institutional environment in which they operate. Rather than focusing on corruption or individual influence, the study approaches state capture as a broader set of mechanisms through which economic elites influence politically decisive arenas and steer public policy toward their interests. The research is grounded in Actor-Network Theory, developed by Bruno Latour, which reconceptualises the “social” as a process of associations among heterogeneous elements rather than a fixed domain explaining social phenomena. From this perspective, political outcomes do not emerge solely from human actors but from networks that include non-human mediators such as legislative bills, legal instruments, technical reports, digital information systems, and material elements like land and agrochemicals. These elements participate in shaping political action and legislative outcomes. Methodologically, the study proposes a cartography of socio-technical networks within the Brazilian Chamber of Deputies. Through this approach, the research maps the heterogeneous actors involved in these networks, traces the relations established among them, and identifies the controversies that structure their interactions. By following the mediations and translations through which demands circulate within the legislative arena, the study demonstrates how certain agendas become stabilised as public policy while others are marginalised, revealing the mechanisms through which dynamics of state capture are produced in contemporary Brazilian agrarian politics.
