Iceberg Lettuce Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Amazon Grocery is the best-performing iceberg lettuce brand in July 2026, moving 150,000 units across 2 ASINs for 25.4% of Top 10 volume. 365 by Whole Foods Market follows with 110,000 units (18.6%), ahead of NatureSweet on 100,000 units (16.9%).

With 7 brands splitting the Top 10 and 61.0% 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 $2.13 to $3.24, 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, B0D4DZF44G leads positive momentum with ▲ 275.0% MoM growth on 3K units, with B0GQV77D38 close behind at ▲ 200.0% MoM on 3K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
