What changed: Marketplace Pulse calculates that Amazon collected $66.1 billion from seller fees and advertising in Q3 2026, equal to 96.6% of the $68.5 billion it made selling goods online itself, up from 89.3% a year earlier, and that on twelve-month numbers the two lines would meet around spring 2028.
When: Published/dated Nov 5, 2026.
Who is affected: Amazon sellers (Best sellers).
What to do: Sellers are increasingly Amazon's customers rather than just its competitors, so the useful number is contribution margin by channel after fees, ads and fulfillment, not the headline referral rate.
