Less than 19% of US digital grocery buyers used Amazon Fresh within the past year. Nearly all of them have also shopped on other digital grocery platforms.

Walmart and the core Amazon site command the largest audiences.

• Amazon Fresh has a smaller audience than the leading players, but it still sits within the top five. Its share of recent digital grocery buyers is similar to Instacart’s and larger than those of leading US grocery chains like Costco Wholesale and The Kroger Co.

• Amazon Fresh also has a larger online audience than Whole Foods Market. The most popular method of ordering grocery products from Amazon is via the core Amazon site, using ship-to-home fulfillment. But among the pure-play grocery channels, Amazon Fresh is more popular than Whole Foods. The latter Amazon-owned grocery brand only received online orders from 7.3% of US digital grocery buyers in the last year.
• Less than 3% of Amazon Fresh shoppers were exclusive to the platform. This isn’t out of the ordinary. Most US digital grocery shoppers (79.9%) bought from more than one platform in the last year. But Amazon Fresh did have a lower percentage of exclusive shoppers compared with industry leader Walmart, where 14.5% of digital grocery customers were exclusive.
• Amazon Fresh customers were more likely than all digital grocery shoppers to also buy groceries on Amazon’s core site. Additionally, more than half have also shopped at Walmart—a slightly lower rate than for all digital shoppers.
