This study examined the market structure, pricing systems, and consumer preferences for breadfruit (Artocarpus altilis) in Ife East LGA, Osun State, Nigeria. Using a purposive sampling technique, three primary markets (Oja-Ife, Adedoyin, and Ajifowobaje) were selected, followed by the selection of 100 respondents, comprising 50 active traders and 50 consumers. Data were analyzed using descriptive statistics, Likert-scale rankings, and marketing margin (MM) analysis to evaluate economic efficiency. Findings indicate that the breadfruit trade is a female-dominated enterprise, with 46% of traders and 32% of consumers within the 41–50 age bracket. Sourcing is primarily from farmlands (72%), with supply peaking during the rainy season (July–August). The marketing channel is characterized by a short distribution chain consisting of producers, village merchants, retailers, and consumers. Transactional analysis shows that bulk procurement occurs in basket units (20–24 fruits) at a mean price of N1,600, while retail trade is standardized into sets of four fruits at N400. Marketing margin analysis revealed a retail markup of approximately N80–N130 per set, which offsets transportation and spoilage risks. Consumer demand is driven by long-standing cultural background and seasonal availability rather than household income, highlighting breadfruit as a socially inclusive staple. However, sustainability is hindered by seasonal scarcity and inadequate storage facilities. The study suggests that improving traditional drying systems and formalizing farm-gate trade units are essential for enhancing market performance, while continued research into varietal improvements and off-season cultivation remains critical for moderating extreme seasonal supply patterns and ensuring a more consistent year-round market.
