Blackout Curtains Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

NICETOWN is the best-performing blackout curtains brand in July 2026, moving 20,000 units across 1 ASIN for 24.4% of Top 10 volume. MIULEE follows with 18,000 units (22.0%), ahead of ChrisDowa on 10,000 units (12.2%).

Volume is spread across 9 brands, with the top three holding 58.5% 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 $9.98 to $17.46, 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, 3 ASINs forced its way in: B0DRFBTSNX booked 5K units at $8.93, with ▲ 66.7% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
