This paper's main argument is that housing financialisation can be understood as a set of intertwined digital/material processes, and that resisting housing financialisation requires activism that recognises and capitalises on this dynamic. Drawing from Desiree Fields' (2017a) work on urban struggles with financialisation, this conceptual argument is unpacked through a case study of post-crash Dublin, an urban space reshaped by housing financialisation and struggles resisting it. Housing has been a key subject of contention in post-crash Dublin and activists' digital/material struggles illustrate how digital technologies and platforms can be and are appropriated to resist housing financialisation. The paper traces the inter-twining of housing financialisation, resistance, and the digital in post-crash Dublin and argues that future research on platform real estate, urbanism, and automated landlord practices must take seriously the ambivalent opportunities, agency, and counter narratives that housing activists create through their digital/material practices.
