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

Magnum Solace is the best-performing magnum brand in July 2026, moving 32,000 units across 2 ASINs for 46.4% of Top 10 volume. TROJAN follows with 30,000 units (43.5%), ahead of POSEIDON on 4,000 units (5.8%).

With 4 brands splitting the Top 10 and 95.7% 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 $7.99 to $21.99, 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: B0FJ92H88H booked 2K units at $7.49. On the growth side, B0031O4B16 leads positive momentum with ▲ 200.0% MoM growth on 300 units, with B000MITQ1Y close behind at ▲ 100.0% MoM on 100 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
