Tervis Tumbler 16 Oz Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Tervis is the best-performing tervis tumbler 16 oz brand in July 2026, moving 3,500 units across 8 ASINs for 76.1% of Top 10 volume. Homestead Choice follows with 700 units (15.2%), ahead of Kensal Home on 400 units (8.7%).

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 $18.99 to $27.78, 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, 3 ASINs forced its way in: B004KXWEAM booked 300 units at $13.99, with ▲ 50.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
