Here we investigate intergroup cooperation in the domain of shotgun hunting in northern Republic of the Congo. In the Congo Basin broadly, forest foragers maintain relationships with neighboring farmers based on systems of exchange regulated by normsand institutions such as fictive kinship. In this study, we examine how relationships between Yambe farmers and BaYaka foragers support stable intergroup cooperation in the domain of shotgun hunting. In the study village, shotgun hunting is based on a specialization-based exchange wherein Yambe farmers contribute shotguns and access to markets to buy cartridges and sell meat while BaYaka foragers contribute their specialized forest knowledge and skill. To understand how costs and benefits are distributed, we conducted structured interviews with 77 BaYaka hunters and 15 Yambe gun owners and accompanied hunters on nine hunting trips. We found that hunts are organized in a conventional manner within a fictive kinship structure, consistent with the presence of intercultural mechanisms to stabilize cooperation. However, because bushmeat demand is high, gun owners can gain significant cash profit, while compensating hunters only with cigarettes, alcohol, and a traditional hunter’s portion of meat. To level payoffs, hunters strategically hide kills or cartridges from gun owners to feed their own families. Our results illustrate how each group prioritizes different currencies (e.g., cash, meat, family, intergroup relations) and provide insights into how intergroup cooperation is stabilized in this setting. The example of this long-standing intergroup cooperative system is discussed in terms of its contemporary entwinement with logging, the bushmeat trade, and growing market intersection.  \u003C/p>\u003Cp>Extended author information available on the last page of the article  \u003C/p>\u003Cp>1 3  \u003C/p>\u003Cp>Keywords Interethnic cooperation · Shotgun hunting · Social norms · Inequality · Foragers · Congo Basin  \u003C/p>\u003Cp>In the evolutionary social sciences, competition between groups has been proposed as key to the emergence of human cooperation (Bowles, 2009; Manson & Wrangham, 1991; Puurtinen & Mappes, 2009; Richerson et al., 2016) . Theoretical and empirical work, for instance, suggests symbolic markers of group membership evolved to facilitate coordination within groups, and that such coordination would be selected for in contexts of conflict with other groups (Handley & Mathew, 2020; McElreath et al., 2003) . Yet, markers of group membership, such as the often-arbitrary traits associated with ethnicity, can also facilitate intergroup cooperation if they are associated with specific roles or products, such as in contexts of trade (Lupo, 2006; Tucker et al., 2021) . Moreover, most intergroup interactions, including those between selfidentified ethnic groups, are peaceful and exhibit stable cooperation across political, economic, and social domains (Bunce & McElreath, 2018; Fearon & Laitin, 1996; Fry & Söderberg, 2014; Pisor & Surbeck, 2019; Rupp, 2011; Tucker et al., 2021) .  \u003C/p>\u003Cp>According to Robinson and Barker (2017), intergroup cooperation is likely to be sustainable when groups exchange resources that each is more efficient at acquiring, leading to a division of labor. This is consistent with the idea that intergroup cooperation between human groups can effectively buffer against local resource shortfalls by spreading risk across the socio-ecological landscape (Cashdan, 1987, 2001a; Colson, 1979; Migliano et al., 2017; Wiessner, 1982) .
