Black Cat Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Mr. Pen is the best-performing black cat brand in July 2026, moving 3,000 units across 1 ASIN for 15.9% of Top 10 volume. Jeasona follows with 3,000 units (15.9%), ahead of LEGO on 3,000 units (15.9%).

Volume is spread across 9 brands, with the top three holding 47.6% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $6.99 to $99.99, 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: B0FH1MJ3T1 booked 1K units at $9.99, with ▲ 42.9% MoM change. On the growth side, B0DB1WC4BN leads positive momentum with ▲ 150.0% MoM growth on 500 units, with B0DS8BCWH2 close behind at ▲ 133.3% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
