NEW YORK, June 27 — The four-day Prime Day retail window that closed Thursday has become a live-fire demonstration of generative artificial intelligence’s ability to reshape online shopping, according to fresh data from Adobe. Online spending on June 23, the opening day of the Amazon-driven stretch, reached $8.3 billion, a 5.3% year-over-year increase. The figure places Prime Day in heavyweight territory: consumers spent $6.4 billion online on Thanksgiving last holiday season, followed by $11.8 billion on Black Friday and $14.2 billion on Cyber Monday.
Adobe now projects that U.S. retailers will generate $26.3 billion in online spending across the full June 23-26 period, representing 9% year-over-year growth and $2.5 billion more than the same window last year. Generative AI sits at the center of that momentum shift.
According to the Adobe data, traffic from AI-powered chat services and browsers jumped 98.3% as shoppers used the tools to compare products, filter deals, and accelerate purchase decisions. The conversion numbers are stark: AI-driven traffic converted 50.7% better than non-AI sources. Shoppers arriving via AI tools spent 49.9% longer on retail sites and viewed 20.5% more pages per visit.
Buy Now Pay Later services played a supporting role in the numbers. BNPL accounted for 6.5% of online orders, generating $668 million in revenue, up 7.6% year-over-year.
Retail discounts remained competitive and broadly aligned with last year’s levels, the data shows. But the AI advantage tilted the field toward faster decision-making and higher-intent traffic. Amazon.com, which started as an online bookstore, now carries a market capitalization of roughly $2.52 trillion.
That chapter sits far in the rearview mirror. The company’s Prime Day event, running from June 23 to June 26, is already shaping up as a showcase of generative AI’s capacity to transform how consumers shop online, the Adobe figures indicate. The timeline is instructive.
On June 23, the opening day hit $8.3 billion in online spending. That single-day total exceeds the $6.4 billion consumers spent online on Thanksgiving last year, though it falls short of the $11.8 billion Black Friday tally and the $14.2 billion Cyber Monday figure.
The four-day stretch is now projected to generate $26.3 billion in total, a $2.5 billion increase over the same period in 2025. What the data does not yet answer is whether the AI-driven conversion rates and engagement metrics will sustain beyond the Prime Day window. The 98.3% jump in traffic from AI-powered chat services and browsers suggests a structural shift in how consumers discover and evaluate products, not merely a promotional spike.
The 50.7% better conversion rate for AI-driven traffic versus non-AI sources points to a tool that is filtering for higher purchase intent. Shoppers using AI tools spent nearly half again as long on retail sites and viewed a fifth more pages per visit.
Those are engagement metrics that retailers typically chase through expensive loyalty programs and targeted email campaigns. Generative AI appears to be delivering them through the front door of the shopping session itself. The Adobe data, released as the Prime Day window closed, provides the first comprehensive look at how generative AI is performing under the pressure of a major retail event.
For Amazon stock watchers, the numbers offer a concrete measure of what the technology can deliver at scale. The question now is whether the pattern holds through the back half of the year.
