Amazon reported its third quarter on October 29, 2026. Third-party seller services grew 9% to $46.5 billion and advertising grew 11% to $19.6 billion, both slower than in Q2. The main reason is the calendar: Prime Day fell in Q2 this year for most large countries, and entirely in Q3 last year.

The numbers sellers should read

Amazon net sales, Q3 2026 against Q3 2025
Line	Q3 2026	Q3 2025	Change
Third-party seller services	$46.5B	$42.5B	+9%
Advertising services	$19.6B	$17.7B	+11%
Online stores	$68.5B	$67.4B	+2%
Total net sales	$201.9B	$180.2B	+12%

Worldwide paid units grew 12%, and third-party sellers made 61% of them. Amazon says net sales growth would have been about 4 percentage points higher without the Prime Day shift.

What Amazon expects for Q4

Net sales of $240.0 billion to $247.0 billion, up 12% to 16%, and operating income of $28.5 billion to $33.5 billion. Amazon also expects advertising growth in the high teens, against 12% excluding currency effects in Q3, which it says was held back by timing tied mainly to Prime Day.

Why it matters

Our read: a high-teens ad forecast means more money chasing the same placements through Black Friday and Cyber Monday, so expect pressure on clicks. On the cost side, peak fulfilment and storage rates are already running, which squeezes margin on the same units.

The release also says Seller Assistant workflows now handle tasks like restocking and pricing, with a plugin connecting it to Amazon Quick and Claude. AI assistants are becoming a normal way to run an Amazon account.

What to do this week

Compare Q3 with Q3 only after adjusting for Prime Day, which moved out of your Q3 too
Rerun your Q4 margin with peak fees and storage in, on your top SKUs
Set a break-even ACOS per product before event bids rise, and watch campaign budgets during the day
