• Purpose This paper aims to formulate the most probable future scenario for the accommodation sharing sector within the next five to ten years. It addresses the following six thematic aspects: relevance, different forms of accommodation sharing, users, hosts, platforms, and finally, industry regulation. Design/methodology/approach This study identifies the most likely holistic future scenario by conducting a two-stage Delphi study involving 59 expert panelists. It addresses 33 projections for six thematic sections of the accommodation sharing industry: relevance, different forms of accommodation sharing, users, hosts, platforms, and finally, industry regulation. Findings The results indicate that the number of shared accommodations and users of home-sharing will increase. Moreover, the cost advantage is the predominant driver for users to engage in the accommodation sharing segment, and for the hosts, the generation of an extra income is the primary incentive. Finally, the regulation within this industry is expected to be morePurpose This paper aims to formulate the most probable future scenario for the accommodation sharing sector within the next five to ten years.

Moreover, the cost advantage is the predominant driver for users to engage in the accommodation sharing segment, and for the hosts, the generation of an extra income is the primary incentive. Finally, the regulation within this industry is expected to be more effective in the foreseeable future. Practical implications The results are critical, not only to advance our theoretical understanding and stimulate critical discussions on the long-term development of accommodation sharing but also to assist governments and policymakers who have an interest in developing and regulating this sector and developers seeking business opportunities. Originality/value While there is ample knowledge about the past and current development of accommodation sharing in tourism, little is understood about its potential future development and implications for consumers, the economy, and society. To date, no scientific research is available that develops scenarios about the future of accommodation sharing.…
