Topic of the Week – Prime Day Expected to Drive $26.3B in U.S. Online Sales
Amazon's extended Prime Day event is expected to provide a significant boost to the U.S. e-commerce market, with Adobe forecasting online sales of approximately $26.3bn, representing a 9% year-on-year increase. The four-day shopping event is also expected to accelerate the start of the back-to-school shopping season and serve as a key demand driver for retailers during the summer months.
While Amazon continues to dominate the summer promotional calendar, competing retailers have once again launched parallel sales events to capture consumer demand. According to Numerator, more than 60% of shoppers plan to compare prices or shop deals at Walmart during the promotional period, while over 40% intend to browse offers from Target. Retailers including Costco, Best Buy and Temu are also expected to benefit from increased traffic and spending, highlighting how Prime Day has evolved into an industry-wide shopping event.
Amazon continues to strengthen its leadership in apparel and footwear. Research from Wells Fargo indicates that Amazon's apparel and footwear gross merchandise value (GMV) has increased from approximately $11bn in 2015 to around $73bn in 2025, with sales projected to reach nearly $78bn in 2026. The company now accounts for more than 13% of total U.S. apparel sales and an estimated 44% of online apparel sales, significantly outpacing competitors and reinforcing its position as a dominant fashion retailer.
Prime Day promotions are expected to drive strong demand across key categories, particularly back-to-school products, travel-related items and home goods. Adobe anticipates increased spending on children's apparel, backpacks, electronics, luggage and household products, as consumers bring forward planned purchases to take advantage of promotional pricing.
The impact of Prime Day is expected to extend beyond digital channels. Bricks-and-mortar retailers running concurrent promotions are also positioned to benefit from heightened consumer interest in discounts. Data from Placer.ai suggests store footfall has continued to recover, creating additional opportunities for omnichannel retailers to capture spending both online and in-store.
Inflation and ongoing cost-of-living concerns continue to shape consumer behaviour. Nearly half of consumers surveyed by Numerator said rising prices make them more likely to shop during Prime Day events, underscoring the importance of value-led promotions in the current environment. However, some consumers remain reluctant to participate due to a lack of immediate purchasing needs, the absence of a Prime membership or perceptions that discounts are insufficient.
Overall, Prime Day and competing sales events have become critical demand-generation moments for the retail industry, increasingly rivalling traditional holiday shopping periods as consumers continue to prioritise value and time purchases around major promotions.
