Best G2 Brands on Amazon US — Top 2 Brand Sales Concentration (July 2026)
PILOT is the best-performing g2 brand in July 2026, moving 106,000 units across 9 ASINs for 91.4% of Top 10 volume. Gatorade follows with 10,000 units (8.6%).
With 2 brands splitting the Top 10 and 100.0% 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 $13.76 to $15.86, which frames the price band a competing listing has to justify.

Trending G2 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: B002FYCICW booked 8K units at $7.49, with ▲ 100.0% MoM change. On the growth side, B07FW8DG5C leads positive momentum with ▲ 500.0% MoM growth on 600 units, with B0030F32L6 close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
