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

365 by Whole Foods Market is the best-performing lettuce brand in July 2026, moving 160,000 units across 2 ASINs for 25.8% of Top 10 volume. NatureSweet follows with 100,000 units (16.1%), ahead of Amazon Grocery on 100,000 units (16.1%).

Volume is spread across 7 brands, with the top three holding 58.1% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $2.08 to $3.73, 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: B00C8XF40I booked 30K units at $2.14, with ▲ 50.0% MoM change. On the growth side, B09VKDGT39 leads positive momentum with ▲ 100.0% MoM growth on 4K units, with B01FCJHWIG close behind at ▲ 66.7% MoM on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
