The purpose of the study was to analyze the current trends in the development of the sharing economy and determine its impact on sustainable development. The article analyzes the dynamics of volumes and the structure of the world market of the sharing economy. The ratings of “Sharing Economy Index,” “STOXX Global Sharing Economy Index,” “MSCI ACWI IMI Sharing Economy Index” were used for the analysis. This made it possible to assess the level of development of the sharing economy at the global level. Both quantitative and qualitative analysis methods were used for the assessment. According to the results of the analysis, it was established that the driver of the development of the sharing market is a change in attitude toward ownership, as consumers have recently preferred the trend of “using instead of owning.” The development of this market is facilitated by the prevalence of digital platforms. Furthermore, the research investigates leading sharing economy enterprises based on their operational scale and market capitalization, thereby identifying key market players and strategic directions for the further evolution of this economic model. The study identifies determinants of growth and assesses the impact of the sharing economy on sustainable development and environmental challenges. In addition, the article examines the adaptive potential of the sharing economy in the context of global socio-economic transformations, highlighting its resilience and ability to integrate into evolving economic structures. Particular attention is given to deficiencies in the current regulatory framework, emphasizing the imperative need for a comprehensive regulatory approach. This approach must integrate technological and legal dimensions to ensure the long-term stability and sustainable development of the sharing economy. It was concluded that the sharing economy contributes to the sustainable development of society under the conditions of its proper regulation.
