16 Oz Plastic Cups With Lids Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Hefty is the best-performing 16 oz plastic cups with lids brand in July 2026, moving 40,000 units across 1 ASIN for 32.5% of Top 10 volume. Dealusy follows with 22,000 units (17.9%), ahead of Amazon Basics on 20,000 units (16.3%).

With 8 brands splitting the Top 10 and 66.7% 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 $6.13 to $27.98, 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: B0GPWRT3KD booked 7K units at $21.99, with ▲ 75.0% MoM change. On the growth side, B0D6VTNX5Y leads positive momentum with ▲ 1100.0% MoM growth on 600 units, with B0GL1VVR5Y close behind at ▲ 900.0% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
