This study examined the role of business learning in entrepreneurial success among traders at Kitala Market. The objectives were to determine the effect of formal business training on entrepreneurial success indicators, to assess the influence of experiential learning on business decision-making and growth, and to examine how peer and networkbased learning shaped entrepreneurial outcomes. A descriptive correlational design was adopted, and primary data were collected from 130 traders using structured questionnaires. Key informant interviews were also conducted with 10 experienced traders and market leadership officials. Quantitative data were analysed using descriptive statistics, Pearson correlation, and multiple regression, while qualitative data underwent thematic analysis. Results indicated that formal business training significantly predicted entrepreneurial success (β = 0.391, p < 0.001), experiential learning had a strong positive effect on business decision-making quality (β = 0.428, p < 0.001), and peer and networkbased learning was significantly associated with improved business growth outcomes (β = 0.344, p < 0.01). The study concluded that business learning in all its forms formal, experiential, and social played a foundational role in the entrepreneurial success of Kitala traders. Recommendations included expanding vocational business training access, establishing peer mentoring circles, and creating structured market learning forums.
