Sleepytime Tea Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Traditional Medicinals is the best-performing sleepytime tea brand in July 2026, moving 28,000 units across 5 ASINs for 50.0% of Top 10 volume. Celestial Seasonings follows with 19,000 units (33.9%), ahead of Amazon Grocery on 7,000 units (12.5%).

With 4 brands splitting the Top 10 and 96.4% 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 $1.99 to $7.97, 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: B006Q5Z02G booked 4K units at $5.88, with ▲ 344.4% MoM change. On the growth side, B0009F3SA0 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0002AUTKY close behind at ▲ 66.7% MoM on 500 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
