Amazon just posted its first-ever $200 billion quarter. In the same stretch, its active seller base fell to a level not seen in years, and new seller sign-ups hit their lowest point in a decade. Both of those sentences are true at the same time. The gap between them is the actual story.
The best quarter the platform has ever reported.
Amazon's net sales rose 20% year-over-year to $200.6 billion for the quarter, the first time total revenue has crossed $200 billion in a single quarter. AWS grew 37% to $42.2 billion, beating analyst estimates of roughly 31% growth and putting the cloud division on a $169 billion annualized run rate. Advertising revenue grew 26% to $19.8 billion. Operating income rose 43% to $27.5 billion. North America segment sales were up 16% to $116.2 billion; international sales were up 15% to $42.2 billion.
Year-over-year growth across Amazon's four headline Q2 lines. Cloud and profit grew fastest, with AWS beating the roughly 31% estimate.
By any measure that matters to Amazon's own shareholders, this is a company firing on every cylinder at once. That is exactly what makes the seller-side numbers worth sitting with.
Because a record platform and a record seller exodus are not actually in tension. They are two views of the same consolidation.
Amazon's active seller base has fallen from 2.4 million in 2021 to 1.65 million by the end of 2025. New seller registrations hit a decade low in 2025, roughly 165,000 new accounts, down 44% from 2024 and the slowest pace of new-seller growth since 2015. The contraction has not leveled off: on Amazon.com specifically, one industry tracker puts active sellers at 584,000 in January 2025, falling to 500,000 by March 2026. That is a different, narrower measure than the multi-year 2.4 million to 1.65 million figure, but it points in the same direction over the most recent stretch.
Amazon's active seller base dropped from 2.4 million in 2021 to 1.65 million by the end of 2025, a decline of roughly 31%.
This is not primarily an Amazon-caused mass exit so much as a rising floor. The businesses walking away are disproportionately casual and undercapitalized sellers, the ones for whom Amazon was a side project rather than a fully resourced operation. The businesses staying are increasingly ones running it like one: real inventory financing, professional content, and a genuine advertising budget, not a listing thrown up and left alone.
It concentrated, sharply, into a small and shrinking share of the seller base.
Fewer than 8,000 sellers, about 1.6% of the active US seller base, now generate roughly half of Amazon's estimated $300 billion in US third-party GMV, down from about 15,000 sellers holding that same position just a few years ago. Over the same stretch that total seller count fell, the number of sellers doing $1 million or more in annual sales grew from about 60,000 in 2021 to more than 100,000 by 2025. At the very top, roughly 235 Amazon sellers now generate more than $100 million a year, up from about 50 a few years ago.
The number of sellers who together make about half of US third-party GMV has fallen from roughly 15,000 to under 8,000.
Over the same period, sellers doing $1 million or more a year grew from about 60,000 to more than 100,000.
The concentration shows up in Amazon's own disclosed numbers too: third-party sellers' share of Amazon's total paid units slipped to 60% in Q1 2026, down from 61% in Q4 2025 and 62% the quarter before, the first quarterly decline in that metric since Amazon began reporting it in 2004. Separately, Marketplace Pulse's 2026 Seller Index, a proprietary cohort study of marketplace sellers, found 38% of sellers in a distressed financial trajectory and only 23% genuinely thriving, describing the market as splitting in two. Tellingly, among sellers most frustrated by rising fees, only 24% say they are reducing Amazon's share of their revenue mix, while 42% say they are actively growing it. The complaints and the continued investment are coming from the same sellers.
A specific, dated set of cost and operational changes, not a vague sense that it is harder now.
Payouts moved from near shipment to seven days after delivery. For a $500K per month FBA seller, that is $100,000 or more in extra working capital just to bridge the wait.
None of these changes are large in isolation. Together, they raise the amount of working capital, operational discipline, and margin cushion required just to keep operating at the same level, which is exactly the kind of pressure a well-capitalized, professionally run seller absorbs and a marginal one does not.
The pattern is consistent enough to describe directly.
| Dimension | Sellers Exiting or Distressed | Sellers Thriving |
|---|---|---|
| Capital posture | Thin inventory financing, cash-constrained, reactive to fee changes | Reserves built for payout delays and fee increases before they land |
| Content and catalog | Minimal listings, few image slots used, no A+ Content | Full listing builds, structured content, ongoing optimization |
| Advertising posture | No ad program, or ad spend cut first when costs rise | Advertising treated as a managed, funded program, not a discretionary expense |
| Operational readiness | Caught off guard by FBA prep, labeling, and compliance changes | Built compliant inbound processes ahead of policy changes |
| Response to rising fees | Complains about fees, does not change allocation or investment | Treats fee increases as a reason to professionalize operations, not exit |
Marketplace Pulse's 2026 Seller Index put 38% of sellers on a distressed trajectory and only 23% clearly thriving, with a shrinking middle in between.
None of this requires being an enterprise brand. It requires operating like a real business rather than a side project, the same distinction that shows up across every Amazon category we manage, not just the ones facing the sharpest cost pressure.
