Purpose This study aims to examine the factors that affect individuals’ intentions of participating in waqf-based crowdfunding model in Kuwait. Design/methodology/approach This study adopted the unified theory of acceptance and use of technology (UTAUT) model. The data were collected by online questionnaire survey based on 419 donors in waqf institutions in Kuwait. The data were analysed using the partial least squares structural equation modelling technique. Findings The results illustrate that performance expectancy, effort expectancy, social influence and facilitating condition positively affect behavioural intention towards waqf-based crowdfunding projects. Practical implications The paper presents an alternative source for waqf institutions to raise capital to develop waqf assets in majority and minority Muslim countries. The findings of this study hold significant implications for government officials and policymakers. Originality/value To the best of the authors’ knowledge, this paper is the first to explore waqf crowdfunding in Kuwait using the UTAUT model. There needs to be more research on waqf-giving behaviour in Kuwait, particularly concerning crowdfunding, which has become more popular recently. Thus, this paper aims to address this gap and contribute new insights to the field.
