Deltarune Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

TOSY is the best-performing deltarune brand in July 2026, moving 3,000 units across 1 ASIN for 39.5% of Top 10 volume. MerryXD follows with 1,000 units (13.2%), ahead of Tokenkuko on 1,000 units (13.2%).

With 10 brands splitting the Top 10 and 65.8% 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 $17.99 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, 2 ASINs forced its way in: B0H6M8N2Z6 booked 200 units at $18.99. On the growth side, B08M9MV99H leads positive momentum with ▲ 100.0% MoM growth on 100 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
