Womens Sports Bras Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

OEAK is the best-performing womens sports bras brand in July 2026, moving 7,000 units across 2 ASINs for 29.2% of Top 10 volume. Tmeefee follows with 4,000 units (16.7%), ahead of CRZ YOGA on 3,000 units (12.5%).

Volume is spread across 9 brands, with the top three holding 58.3% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $19.99 to $29.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B088M5Z6ZR booked 2K units at $18.99. On the growth side, B08NXC2CMC leads positive momentum with ▲ 400.0% MoM growth on 1K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
