Adobe Analytics reported on Wednesday that online purchases by U.S. shoppers totaled $8.3 billion on the first day of Amazon's Prime Day, representing a 5.3% increase from the same day a year earlier. The shopping period runs for four days and began on Tuesday, earlier than in previous years.
Adobe characterized the opening day as tracking ahead of its internal projections and noted it was the largest e-commerce day observed so far in 2026. The data firm reiterated its earlier forecast that U.S. retailers would record $26.3 billion in online spending over the full span of the event.
Sales, Adobe said, were concentrated in a handful of categories including electronics and appliances as well as tools and home improvement. The firm also highlighted a rise in purchases of everyday essentials, indicating that consumer demand for routine items ticked up during the promotion.
Discounting on day one fell within a band Adobe described as 10% to 24%, and the company expects that range of discounts to persist across the event. Adobe's projections and reporting draw on a broad dataset: the firm's analysis covers 1 trillion visits to U.S. retail e-commerce sites, spans 100 million stock keeping units and includes 18 product categories.
Methodology note: Adobe's figures are based on its analysis of web traffic and product-level activity across U.S. retail e-commerce sites as described above.
The early start to this year's Prime Day positions the event as a near-term gauge of consumer spending behavior - in particular, how promotional activity influences purchases across discretionary categories like electronics and home-focused segments as well as routine spending on essentials.
Observers will watch whether the pace of online sales through the remaining days of the promotion aligns with Adobe's $26.3 billion projection and whether the reported discounting band holds.
