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

NICETOWN is the best-performing blue blackout curtains brand in July 2026, moving 21,000 units across 2 ASINs for 40.4% of Top 10 volume. ChrisDowa follows with 10,000 units (19.2%), ahead of 100% Blackout Shield on 7,000 units (13.5%).

With 8 brands splitting the Top 10 and 73.1% 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 $32.97, 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, B07C9HL1G1 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B07VPKR5FF close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
