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

Core Power is the best-performing koia brand in July 2026, moving 40,000 units across 1 ASIN for 19.0% of Top 10 volume. Oikos follows with 40,000 units (19.0%), ahead of Oatly on 40,000 units (19.0%).

Volume is spread across 8 brands, with the top three holding 57.1% 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 $4.99 to $41.88, 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, B096H8LPP2 leads positive momentum with ▲ 100.0% MoM growth on 20K units, with B083FK646P close behind at ▲ 100.0% MoM on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
