Amazon’s latest Prime Day event has shattered expectations, recording a massive $24.1 billion in online spending, up 30.3% from last year. Held over four days from July 8 to 11, 2025, the extended Prime Day campaign outpaced last year’s two Black Fridays combined, according to Adobe data. Deeper discounts and strong back-to-school demand played a role, but the most decisive factor was the exponential rise in AI-driven shopping behavior.
A sharp increase in traffic from generative AI tools has added a new layer to how consumers shop online. With AI now baked into user journeys, this year’s Prime Day wasn’t just longer, it was smarter. The numbers confirm AI’s growing impact on e-commerce trends and the way platforms like Amazon are benefiting from it.
AI-Powered Shopping Sees 3,300% Traffic Spike
One of the most dramatic shifts came from the surge in AI-generated traffic to e-commerce platforms. Adobe claimed a jaw-dropping increase of 3,300% for site traffic during Prime Day. That jump suggests that something about how tools, like AI-based chatbots, shopping assistant tools, and personalized product recommenders, are working together to influence consumers’ purchasing behavior.
Gartner’s 2023 report suggested that 66% of enterprises were already leveraging AI to boost productivity. During Prime Day, these integrations worked with consumer-facing AI to inform decisions, curate product selections, and speed up the checkout process. For many buyers, AI didn’t just assist, it made decisions. Such dramatic traffic growth from AI signals a broader trend: shoppers increasingly rely on machine-driven suggestions over traditional browsing. As Amazon continues expanding its AI capabilities, the connection between AI and online spending will only tighten.
Mobile Commerce Driven by AI Nudges
Another major trend was the dominance of mobile. 53.2% of all Prime Day sales—roughly $12.8 billion—came from mobile devices. AI played a quiet but powerful role here, too. Personalized alerts, voice search integration, and predictive recommendations help usher users into a quicker environment to make purchases through their smartphones. This shift matches Nielsen’s 2024 Mobile Commerce Report, showing 60% of shoppers prefer mobile for the convenience factor.
But this year’s Prime Day established that it is not just about convenience now, it is about the efficiency of AI and digital tools. As AI tools assisted and enhanced the mobile experience for users, passive or casual scrolling of the app turned into high-converting sales transactions. Now, as Amazon builds all the mobile-first shopping data with AI on top of it, desktop shopping continues to decline. The PM mobile spike highlights the shift of user behaviors, especially with machine intelligence breathing down their necks, taking full advantage of those micro-moments of purchase.
Enterprise AI Adoption Shapes Consumer Habits
What happens behind the scenes at companies is increasingly shaping what consumers experience on the front end. Amazon’s Prime Day success was built on more than just discounts. It reflected a deeper shift in how businesses deploy AI at scale. Gartner’s data shows that two-thirds of businesses already use AI internally. That adoption ripples out.
Whether through smarter ad placements, dynamic pricing models, or targeted inventory management, these enterprise AI systems shaped what appeared before shoppers during Prime Day. In turn, consumers responded to those cues, many unknowingly. With AI refining both supply and demand, the scale of Amazon sales during Prime Day shows how much AI can move the needle in real time. Companies that tap into AI aren’t just gaining operational efficiency; they’re driving direct revenue growth.
AI Takes Center Stage in E-Commerce Growth
There was more than just length to Amazon’s extended Prime Day – it was AI-powered throughout the experience. From the 3,300% increase in AI-aided traffic to the $24.1 billion in e-commerce, all signals point to a future in which AI is a core component of the e-commerce experience. Mobile transaction volumes have surged, desktop transaction volumes have declined, and consumers have approached transactions using an AI capability, whether that be chatbots, predictive shopping assistants, or recommendation engines.
As organizations deepen their integration of AI, companies like Amazon will take advantage of the implications for scaling sales, personalizing customer engagement, and accelerating conversion. The outcome? AI is no longer in the background. It’s the engine driving online spending and defining how Amazon sales will evolve in the years to come.
