Best Baby Shark Birthday Decorations Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)

Volume is spread across 10 brands, with the top three holding 53.2% 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 $5.97 to $12.67, which frames the price band a competing listing has to justify.

Trending Baby Shark Birthday Decorations Products — Growth Leaders & New Top 10 Entrants
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: B0FS11HHX1 booked 2K units at $7.98. On the growth side, B0GDG26377 leads positive momentum with ▲ 700.0% MoM growth on 400 units, with B0GTMGSBDF close behind at ▲ 300.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
