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

Fresh Produce (Brands May Vary) is the best-performing butter lettuce brand in July 2026, moving 90,000 units across 3 ASINs for 22.0% of Top 10 volume. organicgirl follows with 80,000 units (19.5%), ahead of 365 by Whole Foods Market on 60,000 units (14.6%).

Volume is spread across 7 brands, with the top three holding 56.1% 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 $2.83 to $3.99, 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: B00KAR6ERQ booked 20K units at $3.49, with ▲ 0.0% MoM change. On the growth side, B0GLPSRC3J leads positive momentum with ▲ 500.0% MoM growth on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
