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

365 by Whole Foods Market is the best-performing yellow mustard brand in July 2026, moving 31,000 units across 4 ASINs for 38.3% of Top 10 volume. HEINZ follows with 17,000 units (21.0%), ahead of French's on 10,000 units (12.3%).

With 6 brands splitting the Top 10 and 71.6% 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 $1.54 to $5.86, 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, one ASIN forced its way in: B08KZ72ZR3 booked 7K units at $2.44, with ▲ 75.0% MoM change. On the growth side, B0GY1K8Z58 leads positive momentum with ▲ 400.0% MoM growth on 4K units, with B000WG65UG close behind at ▲ 150.0% MoM on 5K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
