Prime Day 2021: The early numbers

Consumers purchased over 250 million items over the course of Amazon Prime Day 2021. In 2019, Prime Day resulted in 175 million items sold.

The event typically occurs every year around the same time, but the ripple effects of COVID-19 forced Amazon to push last year’s event from a summer timeline to October. With less time in between Prime Days, it’s possible that 2021 saw smaller year-over-year sales growth than previous years.

Gross merchandise volume (GMV) was up approximately 7% year-over-year, reaching $9.55 billion. In 2020, GMV grew 54% year-over-year.

The halo effect was also in full force, with total U.S. ecommerce sales for Amazon and its competitors (including Walmart, Target, Best Buy, and Kohl’s) reaching $11 billion over the course of Prime Day. That’s 6.1% higher than the total ecommerce sales seen over Amazon Prime Day 2020.

June 20 was the biggest day yet in 2021 for overall ecommerce sales in the US.

More estimated sales numbers are expected to come as more data rolls in and gets analyzed. Stay tuned for more stats and data specific to Prime Day 2021.

Supporting small businesses

To align with consumers’ heightened interest in supporting small and local businesses last year, Amazon featured special promotions for small businesses last Prime Day.

A “spend $10, get $10” promotion for Prime members who purchased from a small business in the weeks leading up to Prime Day helped drive $900 million in total sales. Third-party sellers (which are mostly SMBs) also broke records in 2020, with Prime Day delivering the two biggest sales days ever.

3P sellers saw sales surpass $3.5 billion from Prime Day 2020 – nearly a 60% increase over 2019.

Amazon’s marketplace sales have steadily declined over each Prime Day due to Amazon heavily promoting its own products. However, the share of marketplace sales went up year-over-year for the first time in 2020. Marketplace sales comprised an estimated 35% of Prime Day sales last year, up from 32% in 2019.
