Amazon Credit Card Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Basics is the best-performing amazon credit card brand in July 2026, moving 30,000 units across 1 ASIN for 34.9% of Top 10 volume. RUNBOX follows with 13,000 units (15.1%), ahead of ZALVEX on 13,000 units (15.1%).

With 8 brands splitting the Top 10 and 65.1% 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 $12.48 to $38.25, 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: B0D7MTYZLQ booked 4K units at $12.99, with ▲ 0.0% MoM change. On the growth side, B0C6LZ8S34 leads positive momentum with ▲ 500.0% MoM growth on 30K units, with B01M5L6BN2 close behind at ▲ 200.0% MoM on 600 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
