Market Size for Athletic apparel in 2026 [Example]

The total available market (TAM) for athletic apparel globally is estimated to be around $300 billion annually. This figure includes a broad audience encompassing fitness enthusiasts, all types of athletes, and casual wear consumers. Considering that about 1 billion people engage in fitness activities regularly worldwide, this figure represents the total number of individuals who could potentially purchase athletic apparel, given the increasing trend towards health and wellness.

The serviceable addressable market (SAM) is determined by considering the specific segment of athletic apparel users who are likely to purchase from small businesses or solopreneurs. With realistic constraints, targeting 5% of the TAM, the SAM for small businesses in this niche is about $15 billion. This reflects approximately 75 million individuals, including gym-goers and active lifestyle enthusiasts who prefer to shop from smaller brands rather than large corporate retailers.

The serviceable obtainable market (SOM) focuses on what can realistically be captured by a solopreneur in the first year of operation. Assuming that you can attract around 1% of the SAM, that translates to a SOM of approximately $150 million in potential sales. This represents around 750,000 customers who are likely to engage with small or newly established brands, considering there is a growing trend for personalized and unique athletic apparel.
