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

ZATAYE is the best-performing happy birthday sign brand in July 2026, moving 10,000 units across 1 ASIN for 21.3% of Top 10 volume. Ovrrcame follows with 7,000 units (14.9%), ahead of Fulmoon on 5,000 units (10.6%).

Volume is spread across 10 brands, with the top three holding 46.8% 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 $9.99, 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. On the growth side, B0CHW7LV9D leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0DRHX5XMS close behind at ▲ 100.0% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
