Nike Shirts Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

ADOREJOY is the best-performing nike shirts brand in July 2026, moving 4,000 units across 1 ASIN for 31.7% of Top 10 volume. Under Armour follows with 2,200 units (17.5%), ahead of Liberty Imports on 2,000 units (15.9%).

With 7 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 $9.99 to $39.95, 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: B077XNW4S9 booked 700 units at $19.99, with ▲ 0.0% MoM change. On the growth side, B07FKBQ2CH leads positive momentum with ▲ 300.0% MoM growth on 200 units, with B07T4V7SBV close behind at ▲ 200.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
