Top Amazon Third-Party Sellers — Q3 2026

September belonged to seasonal sellers. While most of Amazon's biggest private-label brands cooled heading into fall, a handful tied to weather, holidays and football season posted the largest gains of the quarter.

This is our first quarterly edition, and the rankings use August and September revenue, the two months with full tracking coverage.

September Belonged to Seasonal Sellers

Where the Big Brands Cooled

Everywhere else, September was flat to soft. Among the top 50 sellers, the median move from August to September was −0.8%. Sixteen fell more than 10%, while only nine rose by that much. Across 1,349 sellers we could compare month to month, revenue eased 3.0%.

The Q3 Leaderboard

A Dead Heat at the Top

OLANLY and AnkerDirect finished August and September just $50M apart. OLANLY earned $2.66B and AnkerDirect $2.61B. Their paths differed, though. OLANLY slipped 9.8% into September, while AnkerDirect held steady at +0.2%, the most stable of the top five.

BulkSupplements: $1.29B
SOLYHUX: $1.28B
College Flags & Banners: $1.25B

Seller Spotlight: College Flags & Banners

Fan Gear in Football Season

College Flags & Banners sells licensed team flags and fan gear, including WinCraft products. It grew from $542M in August to $709M in September as the college and NFL seasons kicked off. That made it the only one of the twelve $1B sellers to grow by more than 10%.

Feedback Is Still Climbing

The seller received 359 feedback ratings in the latest 30 days, up 65% from 218 in the prior window.

Beyond Revenue

U.S. Sellers Earn More Than Their Share

U.S. sellers took 67.4% of August and September revenue, China 20.8%, and Hong Kong 6.6%. Chinese storefronts make up 26.2% of sellers but earn only 20.8% of revenue.

The monthly U.S. share stayed between 66.8% and 68.0% all quarter. That makes it a dependable baseline for Q4.

Feedback Tells a Different Story

ZEAGOO collected the most feedback across August and September, 5,917 ratings, despite ranking #231 on revenue. Carlyle (5,851) and AnkerDirect (4,833) are the only sellers in the top 15 on both boards.

Price vs. Volume

Seven of the 100 highest-grossing ASINs in the latest 30 days are sold by the brand that makes them. Resilia Oregano's oil of oregano softgels led that group at $1.35M. AnkerDirect was the only brand to place twice.

Two very different routes reached the same revenue. Flexpedic's hybrid king mattress earned $579,990 from 1,000 units. Native's shampoo set needed 30,000 units to earn about the same.

A Note on the Data

CGK Unlimited's September estimate fell to $87.8M from $1.58B in August. The October D2C Brands page lists it at $2.09B for the latest 30 days. We've left it out of the comparisons above while the figure is under review.

Full-quarter totals including July are in the report, marked as estimates.
