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

Clorox is the best-performing comet brand in July 2026, moving 100,000 units across 1 ASIN for 64.1% of Top 10 volume. Bar Keepers Friend follows with 30,000 units (19.2%), ahead of Stardrops on 10,000 units (6.4%).

With 9 brands splitting the Top 10 and 89.7% 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 $5.24 to $15.97, 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, B01JN1XLH0 leads positive momentum with ▲ 150.0% MoM growth on 500 units, with B0FW97XZWX 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
