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

Organic Valley is the best-performing organic valley milk brand in July 2026, moving 90,000 units across 3 ASINs for 33.3% of Top 10 volume. Fairlife follows with 50,000 units (18.5%), ahead of Oatly on 30,000 units (11.1%).

With 7 brands splitting the Top 10 and 63.0% 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 $4.78 to $6.36, 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: B00QM3M00W booked 20K units at $4.78, with ▲ 100.0% MoM change. On the growth side, B07PBFNYXV leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B00QM3LZGC close behind at ▲ 50.0% MoM on 30K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
