TikTok Shop boosts TikTok’s huge potential as an e-commerce platform that encourages sellers and buyers to increase the number of transactions. The emergence of this feature encourages the online impulse buying phenomenon on the TikTok platform. This study aims to examine the factors that influence online impulse buying on TikTok in Indonesia through the constructs of brand review, sales promotion, customer satisfaction, religiosity, and brand expectation. This quantitative research uses a questionnaire that is distributed randomly online and collected from 312 respondents in Indonesia. Using structural equation modeling (SEM), data analysis was conducted and hypotheses were examined. The results show that customer satisfaction (β: 0.501) and brand review (β: 0.358) play an important role in increasing brand expectation. At the same time, sales promotion (ρ-value > 0.05) has no impact on brand expectation. This study highlights that religiosity (β: –0.239) and brand expectation (β: –0.510) can reduce online impulse buying behavior. Brand expectation (β: –0.510) is the most dominant variable in reducing online impulse buying behavior on TikTok.
