Yellow Onion Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Fresh Produce (Brands May Vary) is the best-performing yellow onion brand in July 2026, moving 460,000 units across 5 ASINs for 48.9% of Top 10 volume. 365 by Whole Foods Market follows with 200,000 units (21.3%), ahead of NatureSweet on 100,000 units (10.6%).

With 5 brands splitting the Top 10 and 80.9% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $1.53 to $3.58, 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: B000RGYJQI booked 100K units at $2.15, with ▲ 66.7% MoM change. On the growth side, B0787Y4VS9 leads positive momentum with ▲ 100.0% MoM growth on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
