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.
