Peanut Butter Cups Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Grocery is the best-performing peanut butter cups brand in July 2026, moving 50,000 units across 1 ASIN for 30.9% of Top 10 volume. Reese's follows with 27,000 units (16.7%), ahead of CLIF Bar on 20,000 units (12.3%).

Volume is spread across 9 brands, with the top three holding 59.9% 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 $5.22 to $17.24, 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, 3 ASINs forced its way in: B0DL2B49T9 booked 20K units at $6.46, with ▲ 900.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
