Insider Intelligence: while Amazon has 39% share of US e-commerce market, it grew by just 0.2% in 2021 and so far in 2022, the slowest rate in years
Sebastian Herrera / Wall Street Journal :
Context & Ripple Effects
The arc here is a hard landing from the pandemic spike: after US e-commerce grew 30%+ in 2020 and Amazon's US retail business expanded an estimated 39% YoY that year, Insider Intelligence now pegs Amazon's growth at just 0.2% across 2021 and so far in 2022 — even as it still commands roughly 39% of the US market.
The stall isn't a one-off blip in the data: Insider Intelligence's later forecast has total US online sales rising only 9.4% to $1T in 2022, the first single-digit year on record, with Amazon itself at 9%. The question the WSJ piece raises is where a company this dominant finds incremental growth when its core channel stops expanding.
First-order effects
- Amazon's retail engine — still nearly two-fifths of US e-commerce — effectively flatlines, shifting pressure onto its faster-growing adjacencies: its digital ad business, which eMarketer already had growing 52.5% to $15.73B on a 10.3% share of the US ad market in 2020.
Second-order effects
- With the category leader barely growing, rivals' gains come disproportionately at Amazon's expense in relative terms, and advertisers following shoppers have more reason to treat Amazon's ad platform as a growth allocation rather than an experiment — reinforcing the shift toward ads and AWS that began when AWS stopped being Amazon's fastest-growing segment back in mid-2020.
Third-order effects
- The pattern held: by Q2 2024 Amazon was still reporting only 5% YoY growth in online stores sales and guiding below estimates, suggesting the 2021-22 stall marked a structural normalization rather than a temporary dip — US e-commerce settling into mature single-digit growth, with Amazon's equity story repriced around AWS and advertising instead of retail volume.
The trend: US e-commerce is transitioning from pandemic-era hypergrowth to a mature, single-digit-growth market, forcing Amazon to derive its growth story from advertising and cloud rather than retail share.
