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

Morovan is the best-performing monomer brand in July 2026, moving 22,000 units across 2 ASINs for 44.9% of Top 10 volume. KDS follows with 10,000 units (20.4%), ahead of VANSISOS on 8,000 units (16.3%).

With 6 brands splitting the Top 10 and 81.6% 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 $4.25 to $9.49, 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: B07WJWGWHP booked 1K units at $21.80, with ▲ 25.0% MoM change. On the growth side, B0FH9XN2TQ leads positive momentum with ▲ 500.0% MoM growth on 300 units, with B0FRFJGGV9 close behind at ▲ 100.0% MoM on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
