This study explores the transformative interplay of social commerce and blockchain technology within the stock market, scrutinising theoretical frameworks and practical implications. Social commerce, blending 'social' and 'commerce', shapes a dynamic digital marketplace, eroding boundaries between interactions and transactions. Simultaneously, blockchain, with its decentralised and secure nature, emerges as a trust foundation in the digital realm. The nexus of these forces redefines finance, introducing heightened security and transparency to social commerce platforms and reshaping the stock market. The study addresses pivotal research questions concerning investor behaviour, predictive analysis, trading strategies, and regulatory challenges. Employing a holistic research methodology, the study contributes valuable insights, bridging disciplines and prompting a re-evaluation of financial models. Envisioning a dynamic coexistence, the review anticipates the transformative potential of this nexus in the evolving financial landscape.
