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

Amazon Grocery is the best-performing half brand in July 2026, moving 50,000 units across 3 ASINs for 46.3% of Top 10 volume. Organic Valley follows with 30,000 units (27.8%), ahead of 365 by Whole Foods Market on 17,000 units (15.7%).

With 6 brands splitting the Top 10 and 89.8% 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 $2.96 to $5.24, 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. On the growth side, B00L7FT90E leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0GV1TKJN7 close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
