Since the 2010s, two worldwide trends have reshaped the urban housing system and induced drastic neighborhood change: the financialization of rental housing and the rise of the platform economy. In China, with continued investment from speculative financial institutions, platform companies aggressively acquired rental houses from individual landlords to develop a platform-based housing rental economy. How does this new rental economy affect housing supply, rents and inequality? This research answers this question by taking Chengdu, China as a case study. A mixed method approach of big data analytics, hedonic pricing model, and field investigations were used to unpack: (a) the pattern of platform houses distribution and its indication of spatial strategies of the financialized platform economy to grab land rent; (b) the effect of such new housing rental economy on housing rents; (c) the effect of the degree of financialization on platform houses' rental prices. The results inform the debate on the disrupt effect of platform economy and housing financialization on equitable urban development, particularly the heterogeneity among cities and countries. This paper contributes to understanding financial investors' glocalization strategy and the state's territorialization strategy as two crucial factors for the variegation of rental housing financialization. •Houses with small living room and more bedrooms that can generate more rent.•Platform companies tend to choose houses nearby public transport services.•High concentration of platform houses increases rental price of surrounding normal houses.•Degree of financialization significantly increases the price premiums of platform houses.
