Amazon ‘s four-day Prime Day event this week could reveal something more important for the e-commerce giant than just a big sales number. Wall Street will be watching to see if Amazon can further cement itself as consumers’ to-go destination for everyday essentials at a time when inflation-weary shoppers are focused on value. Prime Day kicks off at 12:01 a.m. PT on Tuesday (or 3:01 a.m. ET) and runs through June 26 at 11:59 p.m. PT on Friday (or 2:59 a.m. ET on Saturday). In addition to tons of deals across more than 35 categories, Amazon is putting an extra incentive on its underpenetrated grocery category — offering an additional 10% off sale items for Prime members. During the online shopping event, media and commerce research firm Emarketer estimates that Amazon’s U.S. Prime Day sales will rise 7.1% year over year to $15.6 billion. That number would account for more than 60% of all the retail sales in the United States for those four days. Not to be outdone, Walmart , Target , Best Buy , and other retailers are launching competing promotions. This is the second year of the four-day Prime Day format. The event started as a single day in 2015, moved to two days in 2019, and went to four days in 2025. It has also been going earlier and earlier in recent years to capture more of the lull in summer shopping, for which the event was created in the first place. By pushing the Prime Day timeline earlier each year, Sky Canaves, analyst at Emarketer, posited that the move is “a way to test whether Amazon can expand the types of purchases consumers make during Prime Day.” Amazon has typically focused on selling in categories that it dominates, such as consumer electronics and other big-ticket items. But in recent years, with elevated inflation sending consumer sentiment to historic lows, there has been a “pronounced shift in terms of the categories that shoppers buy,” Canaves explained. Inflation, as measured by the consumer price index, accelerated to 4.2% year-over-year growth in May, the highest level in three years. It was driven largely by higher energy costs tied to the Iran war. (At the time, Jim Cramer was on record , saying oil prices should come down when the war ends. That is what is happening now, but won’t show up in the economic numbers for a while.) Higher prices put additional pressure on household budgets and increase consumers’ appetite for discounts and value. There has been a lot more “budget consciousness,” Canaves said. The Prime Day shopper has become more interested in deals on everyday essentials, and groceries, as well as personal care, and beauty items. It’s these “smaller ticket items that they will use Prime Day to stock up on,” the Emarketer analyst added. It’s a trend that is supported by recent consumer surveys. According to an April survey by marketing platform Omnisend, 53% of respondents cited steep discounts as their primary motivation for shopping Prime Day. The survey found 55% of U.S. consumers plan to…
