The aim of this article is to provide insight on how claims that sport contributes to development or peace are transformed into facts. Beyond a theoretical discussion about how sport for development and peace (SDP) facts are built, this article demonstrates, in rich detail, the subtle art of SDP fact building for funding purposes. Specifically, through an integrative literature review and two case studies, a mix of fact-building actors composed of experts, literature, and allies, is exposed and analyzed. Furthermore, a conceptual model that synthesizes the relationship between the mix of fact-building actors and contextually predisposed funding agencies is also proposed.
