Back to all
The short of it
- Shoppers arriving from AI tools converted 40% better than shoppers from paid search and email during Prime Day 2026, per Adobe. A year earlier, that same traffic converted worse than every traditional channel.
- Alexa for Shopping lets Prime members set price targets that buy automatically. Your October discount can fire a purchase the second it goes live.
- Demand spread well past Amazon. Rithum client sales on Target grew 31% during the event window.
- Amazon hasn’t announced October dates yet. Last year’s event ran October 7–8. Count your prep backward from there.
Prime Day 2026 produced the first hard evidence that AI shopping assistants move the numbers during a major online shopping event. Traffic from LLMs like ChatGPT and Perplexity grew 89% over last year’s event and converted 40% better than channels like paid search and email, according to Adobe. Twelve months earlier, that same traffic converted worse than every traditional channel.
We covered the full results, including category rankings and client growth, in part one of this series. This post is part two. It covers what that conversion flip changes about your prep for October’s Amazon event and Black Friday Cyber Monday.
Why did AI traffic suddenly start converting?
The shopper finished comparing inside the assistant. When someone asks ChatGPT or Gemini for the best carry-on under $150, the assistant reads product data, compares candidates, and returns a short list. The click that follows carries a decision already made.
Amazon built the same behavior into its own storefront. Alexa for Shopping, which replaced Rufus in May, sits in the search bar and product pages and answers customer questions from listing content. If an attribute is missing from your listing, the assistant answers with someone else’s product.
The work that wins these sales happens weeks before the event, inside your catalog. Our GEO for commerce guide breaks down what AI agents evaluate and how to check whether they recommend you.
How do price alerts and auto-buy change deal planning?
Alexa for Shopping hands Prime members tools that price-tracking sites used to provide. Shoppers can build personalized deal guides, set price alerts, trigger an automatic purchase when a product hits a target price, and review 365 days of price history.
Here are two features to consider:
- Auto-buy turns your discount into a trigger. A shopper who sets a $79 target on your product in August buys the moment your October price crosses it. Demand queues up ahead of the event and executes on its own. Decide your price floors before the event starts, because the purchase fires the instant you hit the number.
- Price history exposes the shallow markdown. An assistant holding a year of your pricing can tell a real discount from a two-week markup reversal, and a shopper can check it in one tap. If your Black Friday price sits above your September price, expect the agent to notice.
Does AI-led demand stay on Amazon?
No. Forrester counted competing sales at nearly every major U.S. retailer during Prime Day week. In our network, client sales on Target grew 31% during the window, and clothing there nearly doubled. Clients selling on more channels captured more of the week’s demand.
Assistants compare across retailers by design. That habit is agentic commerce in practice. A shopper asking for the best price on a specific product gets an answer pulled from every storefront the model can read, resulting in the recommendation. If your price, stock, or content differ by channel, the AI assistant sees the gap before your team does and your product doesn’t appear in that conversation.
This year, Amazon’s fall event will run against competing sales at other major retailers, and assistants will compare all of them at once.
What should brands do before October’s event?
Amazon hasn’t announced dates for Prime Big Deal Days 2026, but last year’s was in October. Our peak season guide maps the full calendar. Here are three things to do to prepare.
• Fix the data AI assistants read. Feed and catalog changes need time to propagate to the platforms shoppers use. Start with your top products and the questions shoppers ask about them. ChatGPT and Perplexity Feeds deliver your product data straight to those platforms.
• Set pricing with standing alerts in mind. Assume price targets already exist against your top products. Review your last 12 months of pricing the way an assistant will, because that history frames how deep your October deal looks.
• Close channel gaps while there’s lead time. If Prime Day demand went somewhere you don’t sell, or somewhere your listings underperformed, start fixing that now. Listings need weeks to stabilize. Keep price and stock in sync across every channel running a competing event.
The same three moves carry into Black Friday (November 27), Cyber Monday (November 30), and the rest of the holiday season, when AI-assisted shopping has another four months of adoption behind it.
Where does Rithum fit?
Rithum moves product data to the channels and AI platforms where shoppers decide. Product feeds keep attributes, price, and stock current everywhere assistants read them. Marketplace listings hold data accurate across 900+ channels while events overlap. Inventory management protects stock during the exact hours demand spikes.
