This paper breaks new ground by revealing and conceptualising the infrastructuring of moral markets as a process that aggregates and integrates experimental sociomaterial practices through the construction and use of local and global knowledge architectures. We follow the moral market infrastructuring work of a project conceptualised as a market intervention to make high quality digital connectivity services accessible to excluded communities in very rural places: making imperfect markets, (more) perfect. In contrast with market studies that focus on the structuring of moral markets, this study explicates the sociomaterial practices that sit beneath such markets, sediment-ing moralities into the infrastructures of markets. In so doing, we characterise the infrastructuring work of moral market-makers, and the construction of different forms of knowledge architectures as a key element of that work. Finally, we reveal how these knowledge architectures capture, reused reform and sediment experimental sociomaterial practices, through the aggregation and integration of moral market action.
