Kewpie Mayo Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

HELLMANN'S is the best-performing kewpie mayo brand in July 2026, moving 29,000 units across 2 ASINs for 26.9% of Top 10 volume. DUKE'S follows with 20,000 units (18.5%), ahead of Chosen Foods on 10,000 units (9.3%).

Volume is spread across 8 brands, with the top three holding 54.6% 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 $4.72 to $7.22, 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: B08P966276 booked 10K units at $7.00, with ▲ 66.7% MoM change. On the growth side, B0D644R7TN leads positive momentum with ▲ 150.0% MoM growth on 2K units, with B00BTV25WK close behind at ▲ 33.3% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
