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

SHAPERMINT is the best-performing spanx brand in July 2026, moving 12,000 units across 3 ASINs for 44.4% of Top 10 volume. SHAPERX follows with 6,000 units (22.2%), ahead of OEAK on 4,000 units (14.8%).

With 5 brands splitting the Top 10 and 81.5% 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 $16.98 to $37.66, 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: B0834LGVTL booked 1K units at $39.99, with ▲ 0.0% MoM change. On the growth side, B0H1Z9NDJP leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B0CRBGXJ8X close behind at ▲ 200.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
