Sweet 16 Party Decorations Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

GREATRIL is the best-performing sweet 16 party decorations brand in July 2026, moving 11,000 units across 2 ASINs for 23.4% of Top 10 volume. PHD CAKE follows with 9,000 units (19.1%), ahead of ZATAYE on 6,000 units (12.8%).

Volume is spread across 9 brands, with the top three holding 55.3% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $5.98 to $11.33, 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, 2 ASINs forced its way in: B0F2HVLZ12 booked 3K units at $5.99. On the growth side, B0BWK8J63Z leads positive momentum with ▲ 185.7% MoM growth on 2K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
