This study analyses the impact emerging platforms for housing allocation might have on the Swedish housing market, through an analysis of allocation platforms and housing queues. The study utilises Fields and Rogers’ (2021) typology of operational and data platforms in order to define and analyse the practices of municipal housing agencies, marketplaces for rental housing, and assistants for managing housing queues, as allocation platforms. Characteristic of allocation platforms, defined within the framework of platform real estate (PRE), is engagement in data collection and valuation. Combining housing applicants’ ‘übercapital’ (Fourcade & Healy, 2017) with queue times creates what I term queue capital. This queue capital serves as a dual process of data-valuation, that allows for valuation of rental housing according to queue time, but also enables housing seekers to access rental housing. Furthermore, housing queues are categorised as strict or indicative based on the rental policies of housing companies: strict queues, commonly used by municipal housing agencies, prioritise the first eligible applicant, whereas indicative queues, prevalent in marketplaces, organise applicants without strictly adhering to queue order.
