Birthday Plates Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Basics is the best-performing birthday plates brand in July 2026, moving 170,000 units across 3 ASINs for 56.1% of Top 10 volume. Dixie follows with 100,000 units (33.0%), ahead of Stack Man on 14,000 units (4.6%).

With 6 brands splitting the Top 10 and 93.7% 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 $5.89 to $25.99, 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: B0883RKWNB booked 4K units at $5.79, with ▲ 100.0% MoM change. On the growth side, B0GVLW5J9N leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0DWJZDN15 close behind at ▲ 100.0% MoM on 400 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
