Amazon grew 12 percent last quarter. The shop where it sells its own goods grew 2 percent.
Both numbers are in the same release. Net sales reached 201,944 million dollars against 180,169 million a year earlier. Online stores, which is Amazon’s own retail rather than the marketplace, reached 68,470 million, a rise of 2 percent.
The release does not set out to explain that gap, and this piece will not pretend to either. What it does contain are two lines that matter more to a seller than either headline figure: advertising, up 11 percent, and third-party seller services, up 9 percent. Both are money Amazon collected, not money anybody sold.
Before any of it travels, one figure needs its denominator attached. Third-party sellers accounted for 61 percent of worldwide paid units in the third quarter, against 62 percent a year earlier. That is a share of worldwide paid units and it excludes Whole Foods Market. Not revenue, not sales value, and not Europe.
What the quarter actually reported
Fourth-quarter guidance is 240.0 to 247.0 billion dollars, which Amazon frames as growth of 12 to 16 percent.
The two seller-facing lines, in full. Third-party seller services reached 46,492 million dollars, up 9 percent, or 10 percent excluding currency movement. Advertising services reached 19,637 million, up 11 percent, or 12 percent excluding currency.
The International segment did 43,108 million dollars, up 5 percent, or 8 percent excluding currency. Its operating income was 1,580 million dollars against 1,199 million a year earlier.

Read the seller-services line correctly
Third-party seller services is the most misread line in the release. It counts what Amazon collected from sellers: referral fees, fulfilment, storage and everything else sellers buy from it. Not what sellers sold. Certainly not what sellers kept.
So a 9 percent rise in that line is not evidence that the marketplace grew 9 percent. It is evidence that the amount Amazon extracted from marketplace activity grew 9 percent. Those two can diverge, and the unit mix this quarter suggests they did: the fees Amazon collected grew faster than the marketplace’s share of units.
This is the frame to carry into any fee conversation. The question a seller should ask of this release is not whether Amazon’s marketplace is growing, but whether the cost of being in it is growing faster than their own volume through it.

What the one point does and does not mean
A single point of unit mix invites overstatement, so be precise about what actually moved.
Over the year the mix moved from 62 percent to 61 percent. That is a real move and the direction is consistent: Amazon’s own retail units grew faster than third-party units over those twelve months. For a seller, the relevant reading is that first-party is not in retreat on the shelf.
Anyone presenting it as a turning point is overreading a noisy series. The same measure has sat at 62, then 61, then as low as 60 earlier this year, before returning to 61 for two consecutive quarters. A one-point annual move inside a band that has already been wider than one point is drift, not a break.
The honest summary is narrow and still useful. The marketplace share of units is flat quarter on quarter, slightly down year on year, and has been moving within a two-point band. Nobody should rebuild a channel strategy on it. Anybody repeating it in a meeting should attach the band.
Come back to that 2 percent. Amazon’s own retail revenue barely moved, while the unit mix shifted toward that same first-party retail. Units up and revenue flat has one general explanation: the average price of what Amazon sells on its own account is falling. Whether that is a deliberate push into cheaper goods, a response to low-price competition, or discounting ahead of peak, this release does not say. For a seller it is the more consequential of the two readings, because a first-party operation winning units at lower prices competes for exactly the buyer a mid-price third-party listing depends on.
The advertising line is the one to watch
Advertising at 19,637 million dollars, growing 11 percent, is the line with the most direct consequence for an operator’s cost base, because advertising cost is the part of a seller’s Amazon bill that is set by auction rather than by rate card.
The mechanism is simple enough. Referral fees and fulfilment fees change when Amazon publishes a change. Advertising cost changes when other sellers bid, which means it can rise in a quarter where no fee schedule moved at all. A seller who budgets fees carefully and treats advertising as a residual has the causality backwards.
Amazon has not published a quarterly advertising growth forecast in this release, so the next quarter’s auction pressure cannot be read from it directly. What can be read is the scale: advertising is now a larger line than the entire International segment’s operating income by an order of magnitude, which tells you where the margin in this business is being made.

Auction costs can rise in a quarter when no fee schedule moved at all, so the early warning has to come from category data rather than from a fee announcement. Our head-to-head of FastMoss and Kalodata looks at how each tool reports category demand and product performance across European markets.

Why International is the segment Europeans should read
The headline figures in this release are worldwide, and worldwide figures are not a European seller’s weather. The International segment is the closer proxy, and it is the one with the more interesting movement.
International grew 5 percent as reported but 8 percent excluding currency, and the gap between those two is itself the story for anyone invoicing in euros or sterling. A European seller’s own reported growth carries the same distortion in the same direction, and a year-on-year comparison that ignores it will overstate a decline or understate a recovery.
Operating income of 1,580 million dollars against 1,199 million is the figure with the longest consequence. A segment generating materially more operating income is a segment better able to fund the things European sellers actually feel: fulfilment network build-out, same-day expansion and the fee reductions Amazon has used to buy volume in individual European stores. That is an inference about capacity rather than a stated plan, and Amazon has announced nothing of the kind in this release.
What a seller does differently on Monday morning
Nothing operational. This is a planning input, not a task, and a quarterly results release rarely produces an action by Monday. Treating it as one is how sellers end up reorganising a channel around a rounding difference.
Three things are worth doing with it over the planning cycle rather than this week.
- Pull your own twelve-month unit growth and compare it against 12 percent, which is what total paid units did. That comparison tells you whether you grew with the platform or against it, and it is a more useful benchmark than any revenue figure in this release.
- Separate your Amazon cost base into rate-card costs and auction costs, and track them apart. Advertising growing faster than fees is the pattern in this release, and a combined “Amazon fees” line will hide it.
- If you report in euros or sterling, restate your own year-on-year numbers excluding currency before you compare them to anything Amazon publishes. The 5 against 8 percent gap in International is the size of the distortion currently in play.
Where the honest uncertainty sits
The unit mix figure excludes Whole Foods Market, and Amazon has not published the segment or geographic breakdown behind it. The 61 percent is therefore worldwide and cannot be read as a European marketplace share.
No advertising growth forecast for the coming quarter appears in this release, so the direction of auction pressure into peak is not established by anything here.
And the connection between International operating income and European investment is a reading of capacity, not a commitment. Amazon has said nothing in this release about European fee changes, network spending or same-day expansion, and a profitable segment is a precondition for that spending rather than evidence of it.
The three-line version
- If you run the account: compare your own twelve-month unit growth against the platform’s 12 percent, and split your cost base into rate-card and auction costs before peak.
- If you have just taken on the channel: the number to repeat accurately is 61 percent of worldwide paid units, excluding Whole Foods, down from 62 a year ago and inside a band that has been as low as 60 this year.
- If you sign the budget: approve nothing on the strength of this release. It contains no European figure, no advertising forecast and no announced fee change.
