Potato Starch Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Argo is the best-performing potato starch brand in July 2026, moving 4,000 units across 2 ASINs for 29.2% of Top 10 volume. Anthony's follows with 4,000 units (29.2%), ahead of Bob's Red Mill on 4,000 units (29.2%).

With 5 brands splitting the Top 10 and 87.6% 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 $5.43 to $16.79, 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: B0FX27H59C booked 900 units at $11.99, with ▲ 28.6% MoM change. On the growth side, B0DW5KNC11 leads positive momentum with ▲ 166.7% MoM growth on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
