Update - May 13, 2026: Amazon launched Alexa for Shopping, folding Rufus into Alexa+ across Amazon.com, the Shopping app, Alexa.com, the Alexa app and hundreds of millions of Echo devices. The same agent now carries one persistent shopper profile across every surface. The actions in this article still apply, but treat them as a baseline rather than a ceiling.

What's Happening

Amazon's Rufus AI shopping assistant has reached 250 million users and is projected to drive $10 billion in additional sales. On November 18, 2025, Amazon rolled out major agentic features that let Rufus autonomously purchase products on behalf of customers. Use a fee-delta view to assess the change rather than relying only on standard reports.

The new auto-buy capability represents a major shift toward agentic commerce. Customers can set target prices and Rufus will automatically purchase when the price drops. Combined with 30-day and 90-day price history tracking, this turns Rufus into a 24/7 deal-hunting agent for Amazon shoppers.

Agentic Commerce Has Arrived

Rufus is no longer just answering questions. It is now making purchasing decisions on behalf of customers. This represents the biggest shift in e-commerce since one-click ordering.

New Agentic Features Explained

Feature	How It Works	Seller Impact
Auto-Buy at Target Price	Customer sets desired price. Rufus monitors and purchases automatically when price drops.	Pricing strategy becomes critical. Dynamic pricing can trigger immediate purchases.
30/90-Day Price History	Shows customers price trends. Flags "good deals" and "wait for better price" recommendations.	Inconsistent pricing hurts. Rufus may tell customers to wait if prices were lower recently.
Voice Reorders	Customers reorder past purchases with voice commands. Rufus remembers preferences.	First purchase matters more. Rufus will keep recommending winners.
Account Memory	Rufus remembers past conversations, preferences, and purchase context.	Brand loyalty compounds. Positive experiences get remembered and referenced.

Cross-Service Memory Coming

Amazon is expanding Rufus memory to Kindle, Prime Video, and Audible. Your product recommendations will soon be influenced by a customer's entire Amazon ecosystem activity.

Why Amazon Chose Agentic Commerce

Amazon filed a lawsuit against Perplexity in December 2025 over its AI shopping agent. The legal action signals Amazon's intent to dominate AI-assisted commerce rather than cede ground to third-party AI shopping tools.

Strategic Moat Building

By building autonomous purchasing directly into Rufus, Amazon ensures that AI-driven shopping happens within its ecosystem. Third-party AI agents cannot compete with an AI that has native access to inventory, pricing, and instant checkout.

Competitor defense: Blocks Perplexity, Google, and ChatGPT from capturing Amazon shopping journeys.
Prime lock-in: Auto-buy works best with Prime. Increases subscription stickiness.
Data advantage: every Rufus interaction trains Amazon's AI on customer preferences.

Impact on Amazon Sellers

Pricing Transparency Is Inescapable

Rufus now shows 30-day and 90-day price history to customers. Price manipulation, fake markdowns, and inconsistent pricing will be immediately visible and may trigger negative Rufus recommendations.

Critical Seller Implications

Opportunity: Products with stable or improving prices will be recommended as "good deals" by Rufus.
Opportunity: Auto-buy creates predictable demand. Customers set price triggers, giving you advance signals.
Risk: Price increases after a low point may cause Rufus to recommend waiting.
Risk: Voice reorders favor established products. New launches may struggle to break into Rufus recommendations.
