Organic Mushrooms Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

365 by Whole Foods Market is the best-performing organic mushrooms brand in July 2026, moving 160,000 units across 4 ASINs for 45.7% of Top 10 volume. Amazon Grocery follows with 130,000 units (37.1%), ahead of RYZE SUPERFOODS on 40,000 units (11.4%).

With 4 brands splitting the Top 10 and 94.3% 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 $2.12 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. On the growth side, B07FXT18R8 leads positive momentum with ▲ 150.0% MoM growth on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
