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

Amazon Grocery is the best-performing mushroom brand in July 2026, moving 130,000 units across 4 ASINs for 59.1% of Top 10 volume. RYZE SUPERFOODS follows with 40,000 units (18.2%), ahead of 365 by Whole Foods Market on 20,000 units (9.1%).

With 6 brands splitting the Top 10 and 86.4% 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 $2.10 to $44.99, 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: B078SZX3ML booked 10K units at $34.95, with ▲ 0.0% MoM change. On the growth side, B07T9KS1DN leads positive momentum with ▲ 40.0% MoM growth on 7K units, with B07XW1BZRN close behind at ▲ 25.0% MoM on 5K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
