Amazon Prime Day Faces Saturation as Most Shoppers Already Have Prime

Amazon's annual Prime Day shopping event, initially conceived to drive new subscriptions to its Prime membership program, is facing a strategic challenge as the company appears to have saturated its addressable market. According to Sky Canaves, a principal analyst for retail and e-commerce at EMARKETER, over 86% of online shoppers in the U.S. are already Prime members, leaving limited room for significant growth in membership numbers.

Launched in 2015, inspired by Alibaba's Singles Day, Prime Day aimed to add new subscribers to the Prime service, which offers benefits like free shipping and streaming. Ten years later, U.S. Prime memberships have surged from approximately 40 million to 200 million. With the membership base nearing its peak, Amazon is reportedly adjusting its Prime Day strategy to focus on increasing spending among its existing members.

This year's Prime Day event, scheduled from June 23 to June 26, will emphasize groceries and essential products, a departure from earlier years that heavily featured electronics and higher-margin items. These less profitable items are being used as loss leaders to encourage more frequent customer visits and capture a larger share of grocery sales, a key battleground with competitors.

Amazon faces stiff competition from retailers like Target and Lowe's, which have introduced their own sales events. Walmart, in particular, is posing a significant challenge with its own membership program, Walmart+, and by offering delivery perks that extend to restaurant meals and groceries, directly competing with Amazon's core offerings.
