Prime Big Deal Days drives nearly $10B in US online spending as bargain hunting intensifies

Amazon’s Prime Big Deal Days, a two-day event built around Prime member pricing and promotions, is drawing attention for the sheer scale of online purchases it generated in the United States. A new industry report estimates that online spending during the event neared $10 billion, underscoring how aggressively large retailers are using short, high-intensity discount windows to pull forward demand.

The reporting focused on total online sales tied to the event across multiple stores, not just Amazon’s own storefront. Amazon’s promotion period also appeared to spill over into competing retail channels, reflecting how consumers often shop across brands when major deals roll out.

Prime Big Deal Days runs as a concentrated shopping push, designed to encourage early purchases rather than waiting for later seasonal markdowns. By pairing member access with time-limited discounts, Amazon effectively turns the event into a countdown, with deals expiring at the end of the window.

The size of the spending figure also suggests the event is competing more directly with other major seasonal sales beats that typically dominate late third quarter and early fourth quarter. In prior years, retailers have used similar tactics to capture bargain hunters before supply constraints and shipping cutoffs become more prominent as the holidays approach.

For Amazon, events like Prime Big Deal Days are not only about revenue during the sale window. They can also help sustain engagement across Prime membership, reinforce the habit of shopping on Amazon during peak promotional periods, and generate additional demand for third-party sellers that rely on Amazon’s traffic and fulfillment infrastructure.

Amazon’s corporate materials describe its retail and services businesses as interconnected, spanning online stores, logistics, and a wider set of digital offerings. Prime itself is a central consumer program in that ecosystem, and deal events are one of the recurring tools used to keep members active throughout the year.

Still, the report did not provide a breakdown in the available material of how much of the nearly $10 billion figure came from Amazon versus other participating retailers, nor did it disclose product-category winners, average order values, or regional performance details. It also did not specify how the estimate was calculated or what time window was used beyond the two-day event framing.

Going forward, the key question for investors and retailers is how effectively these short, promotional surges translate into longer-term consumer behavior. If shoppers who buy during Prime Big Deal Days continue purchasing later in the season, Amazon and its rivals could benefit beyond the event dates. If not, the competitive advantage may prove more temporary, driven primarily by deal-driven demand.
