Gain Flings Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Gain is the best-performing gain flings brand in July 2026, moving 170,000 units across 6 ASINs for 58.6% of Top 10 volume. Tide follows with 70,000 units (24.1%), ahead of Arm & Hammer on 50,000 units (17.2%).

With 3 brands splitting the Top 10 and 100.0% 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 $2.98 to $22.59, 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: B0CCGC3C32 booked 20K units at $1.88, with ▲ 100.0% MoM change. On the growth side, B0CCK2MP67 leads positive momentum with ▲ 300.0% MoM growth on 4K units, with B0FG58W4KG close behind at ▲ 100.0% MoM on 40K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
