Platforms are transforming society, economy, and politics and becoming essential infrastructures of our lives. In this way, digital spaces overlap with other spatialities, urban areas in particular. This process is not peaceful but generates bottlenecks, resistances, and oppositions. In this article, we propose to combine platform studies with infrastructure studies to frame the capacity of such enterprises to build new urban postindustrial environments. We focus on the potential conflicts emerging in the face of the growing platformization and sketch the outlines of a counter-platform politics.
