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

NICETOWN is the best-performing brown blackout curtains brand in July 2026, moving 21,000 units across 2 ASINs for 33.9% of Top 10 volume. ChrisDowa follows with 10,000 units (16.1%), ahead of MIULEE on 10,000 units (16.1%).

With 8 brands splitting the Top 10 and 66.1% 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 $11.99 to $24.95, 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. On the growth side, B08V8HD2WT leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B07VLBQ1FC close behind at ▲ 166.7% MoM on 800 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
