Stok Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

STOK is the best-performing stok brand in July 2026, moving 60,000 units across 2 ASINs for 35.3% of Top 10 volume. Chobani follows with 30,000 units (17.6%), ahead of Starbucks on 30,000 units (17.6%).

With 7 brands splitting the Top 10 and 70.6% 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 $5.26 to $13.98, 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: B08B4FFBTQ booked 10K units at $3.56, with ▲ 42.9% MoM change. On the growth side, B08SFLBLWX leads positive momentum with ▲ 250.0% MoM growth on 700 units, with B09CK1WN7M close behind at ▲ 250.0% MoM on 700 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
