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

Amazon Grocery is the best-performing peanut butter brand in July 2026, moving 60,000 units across 2 ASINs for 33.3% of Top 10 volume. SKIPPY follows with 40,000 units (22.2%), ahead of 365 by Whole Foods Market on 30,000 units (16.7%).

With 6 brands splitting the Top 10 and 72.2% 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 $4.92 to $6.72, 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: B0DL2B49T9 booked 20K units at $6.46, with ▲ 900.0% MoM change. On the growth side, B07KWGSCW2 leads positive momentum with ▲ 300.0% MoM growth on 8K units, with B0BDTBBHD1 close behind at ▲ 66.7% MoM on 50K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
