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

KKBESTPACK is the best-performing poly brand in July 2026, moving 20,600 units across 2 ASINs for 75.2% of Top 10 volume. PLT follows with 4,500 units (16.4%), ahead of POLY on 1,000 units (3.6%).

With 5 brands splitting the Top 10 and 95.3% 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 $27.96 to $101.14, 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: B09BBSB3J4 booked 500 units at $108.01, with ▲ 0.0% MoM change. On the growth side, B0C6FP93LJ leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B07X41JJXB close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
