Oat Bran Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Bob's Red Mill is the best-performing oat bran brand in July 2026, moving 21,000 units across 3 ASINs for 27.3% of Top 10 volume. Quaker follows with 15,000 units (19.5%), ahead of Grape-Nuts on 10,000 units (13.0%).

Volume is spread across 7 brands, with the top three holding 59.7% 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 $5.29 to $15.47, 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: B0BG1G3PFN booked 5K units at $4.42, with ▲ 25.0% MoM change. On the growth side, B07C31TV8Q leads positive momentum with ▲ 100.0% MoM growth on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
