As Amazon Prime Day Approaches, Growth Shows No Sign of Slowing

Next week is Amazon Prime Day 2017, which the ecommerce titan describes as “one of the world’s best days to shop.”

It’s the company’s third such day since launching Prime, a membership that, for an annual or monthly charge, promises unlimited two-day shipping on all orders, and other perks like video and music streaming libraries and cloud storage.

While Amazon does not officially disclose numbers around Prime, new data from Consumer Intelligence Research Partners shows that the company’s subscription service continues to grow at an impressive rate. CIRP pegs current membership at 85 million in the US alone, up 35% from last year, and double 2015’s figure.

CIRP also notes that Prime members spend nearly twice as much per year on average than non-members ($1,300 vs. $700).

Prime is a core pillar of Amazon’s business now, alongside ecommerce, cloud services, and groceries, as emphasized by a massive Whole Foods acquisition recently.
