CIRP: the number of US Amazon Prime members remained at ~172M as of June 30, the same as six months earlier, after Amazon raised prices in February 2022
Spencer Soper / Bloomberg : Tweets: @spencersoper Tweets: @spencersoper : Looks like $139 a year for Amazon Prime is a bit much for some folks. Growth stagnated in the US so far this year. They had to hit the ceiling eventually. https://www.bloomberg.com/...
Context & Ripple Effects
Prime's US growth curve was already flattening before the fee hike: CIRP counted 85M members in mid-2017 growing 35% a year, but by late 2018 that pace had cooled to 8% on 97M members. In February 2022 Amazon pushed through its first major price increase, lifting the annual fee $20 to $139 ($139-a-year repricing).
Six months later, CIRP's count is frozen at ~172M — zero net adds — suggesting churn among price-sensitive households exactly offset new signups. The eventual rebound matters for reading this moment: by March 2024 CIRP recorded a new high of 180M US members, so the stall looks like a plateau at the price change, not a permanent ceiling.
First-order effects
- Amazon booked the higher $139 fee across an unchanged 172M base — revenue per member rose with no membership growth to compound it.
- Households that let Prime lapse after the March 25, 2022 increase for existing members were replaced one-for-one by new signups, meaning Amazon lost none of its installed base despite the hike.
Second-order effects
- With headcount flat, Amazon's lever shifts to deepening what membership includes — the related coverage shows it pushing perks like expanded Prime Air drone delivery and making Alexa+ free on Fire TV regardless of Prime status, value-stacking aimed at retention rather than acquisition.
- Rival retail subscription programs lose their easiest recruiting pool: with roughly three-quarters of US shoppers already holding Prime by 2024, competitors are fighting over the same remaining non-members Amazon couldn't convert at $139.
Third-order effects
- If the pattern holds, US Prime becomes a penetration-saturated asset judged on spend per member and attach rates rather than subscriber counts — the metric that mattered when membership doubled in two years in 2017 gives way to ARPU-style economics.
- A mature subscription base also raises the stakes on every future price move: each hike now trades directly against churn in a way it didn't when growth was masking losses, pushing Amazon toward quieter monetization (ads, bundled services) over headline fee increases.
The trend: US Prime is transitioning from a land-grab subscription whose value was member count to a saturated one whose value is extracted per member, with pricing power now capped by churn.
