AI Agents in E-commerce: From Chatbots to Autonomous Commerce (2026)

Your customer service chatbot is not an AI agent. And that's going to be a problem.

Here's the difference: a chatbot follows a script. It answers "where's my order?" with a tracking number. It's reactive. It waits for a question and gives a pre-programmed answer.

An AI agent acts. It observes, decides, and executes. It doesn't wait for a question—it anticipates a need.

The distinction matters because we're in the middle of the biggest shift in e-commerce since the launch of the shopping cart. Agentic commerce—where AI agents discover, compare, and purchase products on behalf of consumers—is no longer a future concept. It's happening now.

Let me walk you through what's actually happening, why it matters for your brand, and what you need to do about it.

Story from Hobiri: A client recently asked us: "Should I care about AI agents?" My answer: "Do you care about the 64% of shoppers who say they'll use AI to make purchases?" That changed the conversation.

What You'll Learn

• What AI agents actually are (and why they're not chatbots)
• Which platforms are leading the shift (Amazon, Google, OpenAI, Perplexity)
• How big the agentic commerce market is getting
• Why your SEO strategy needs to change
• What you can do right now to get ready

AI Agents vs. Chatbots: The Difference That Matters

Let me be direct about this distinction.

A chatbot follows a decision tree. It matches keywords to responses. It's useful, but it's scripted.

An AI agent combines:

• Memory: Recalls user preferences and past behavior
• Tool access: Connects to retailer databases, payment systems, and product catalogs
• Multi-step reasoning: Can plan and execute complex tasks without step-by-step instructions

Here's the example I give clients: a chatbot recommends a moisturizer based on your skin type. An AI agent queries multiple skincare brands, compares ingredients and prices, and picks the best option for you—then buys it. That's the difference between reactive and autonomous.

The Size of the Opportunity

This isn't a niche trend. The numbers tell a clear story.

The gap between current and projected market size tells you everything. We're in early-stage, accelerating adoption.

Retailers that deployed AI capabilities saw 14.2% sales growth between 2023-2024, compared to 6.9% for those that didn't. That gap is widening.

The Five Players Shaping Agentic Commerce

Five major platforms are building the infrastructure for AI-driven shopping:

1. Amazon

Amazon is positioning itself as the primary gateway for AI discovery. 63% of consumers already begin product searches on Amazon rather than on search engines.

Through its Buy for Me feature (powered by Amazon Nova and Anthropic's Claude), customers can now buy from third-party brand sites without leaving Amazon's interface. The agent navigates to the retailer's site, adds the product to the basket, enters shipping and payment details, and completes checkout.

Amazon also offers Auto Buy, letting shoppers set price targets while Rufus monitors products and purchases automatically when thresholds are met. Early evidence suggests an average saving of 20% per purchase for Prime members using these tools.

Strategic move worth noting: In July 2025, Amazon withdrew entirely from Google Shopping advertising in the U.S. They're betting that Amazon—not Google—will be the primary gateway for product discovery.

2. OpenAI (ChatGPT)

ChatGPT has the broadest general-purpose user base and has moved from advice into transactions through checkout partnerships with Etsy, Shopify, and Walmart. OpenAI also launched Instant Checkout in 2025 with partners including these major retailers.

3. Google (Gemini)

Google's Universal Commerce Protocol (UCP) is an open standard co-developed with Shopify, Etsy, Wayfair, and Target, with more than 20 companies endorsing it. UCP enables AI agents to complete shopping transactions across retailers and payment providers without custom integrations.

Google's AI Mode uses the Shopping Graph's 50 billion-plus product listings to enable conversational product discovery and checkout.

4. Perplexity

Perplexity is positioned more as a research-led tool with particular strength in comparison-heavy purchases where citations and side-by-side reasoning matter. It has integrated with PayPal to enable checkout within the chat.

5. Meta

Meta's Business AI delivers personalized recommendations and direct purchasing across Facebook, Instagram, and Shopify-powered sites.

What This Means for Your Brand

The shift is creating an existential challenge. As AlixPartners puts it: "Retailers risk being relegated to just a supply chain role."

When discovery, evaluation, and checkout shift into agent channels, retailers lose direct control of the digital journey. That means:

• Less online customer data – You lose visibility into behavior, intent, preferences, and switching patterns
• Weaker brand loyalty – The customer relationship is mediated by the agent
• Reduced upselling – Agents are more likely to focus on explicit task completion, not impulse purchases

Alex Baldock, Currys CEO and incoming Boots CEO, made an important point at the 2026 World Retail Congress: agentic AI may amplify incumbent strengths like trust, review depth, service reputation, and scale. Trusted omnichannel incumbents may be better positioned than simple "commodity" retailers.

Story from Hobiri: The same principle applies to e-commerce brands. If you've built a reputation for quality, reliability, and service, AI agents will surface that. If you've built a commodity business, you'll compete on price alone—and lose.

The Technical Shift: What Brands Must Do

1. Invest in Generative Engine Optimization (GEO)

Traditional SEO assumed a human shopper reading search results. AI agents don't browse—they read structured data.

What to prioritize:

• Structured product metadata – clear specs, pricing, and availability that AI agents can parse
• Indexable review sections – customer reviews in formats AI systems can extract and cite
• Full-sentence product descriptions – complete descriptions AI chatbots can include in outputs

Some brands have already scaled content production from 3-4 pieces per month to over 100, optimizing for AI extraction. Brooklinen pays influencers to promote products on social channels knowing that transcripts will be scraped by AI crawlers.

2. Enable Agentic Transactions

The infrastructure for agentic checkouts is now available. You can list and sell products through:

The key: Once you enable these channels, you remain the merchant of record. You own the customer relationship and data. Orders flow into your admin with attribution showing which AI channel drove each sale.

3. Control Your Brand Voice in AI Conversations

AI agents pull from FAQs, return policies, shipping information, and pricing data to answer shopper questions. If a shopper instructs an agent to "only buy from brands with free returns," the agent will only consider your products if you clearly state your free returns policy.

Shopify's Knowledge Base app gives merchants control over what AI agents say about their brand by providing structured, verified answers. Upload return policies, shipping information, brand voice guidelines, and FAQs. When an AI agent answers a question about your store, it references verified information instead of generating a guess.

The Governance Question

A fundamental question sits alongside the tactical steps: do you want to be available to agents at all?

Retailers face a binary choice:

• Open the catalog to ChatGPT, Gemini, Perplexity, and others—competing to be the agent's recommendation
• Block agent access and force customers to come directly

Amazon has chosen the latter: rather than feeding third-party agents, it built Rufus and Buy for Me, withdrawing from channels it doesn't control. Shopify has taken a different approach: building infrastructure to make merchants discoverable across all AI surfaces.

There's no single right answer. But you need to make a deliberate choice.

J.P. Morgan's Framework: Crawl, Walk, Run

J.P. Morgan describes agentic commerce as a journey, not a sprint. Their framework maps directly to what we've been discussing:

Most brands are still in the "crawl" phase. That's okay. But you need to start now.

Frequently Asked Questions

Next Steps

Ready to start preparing for agentic commerce?

Here's what I'd do if I were in your shoes:

Week one: Audit your structured product data. Is it complete, specific, and machine-readable? Use Shopify's free audit tool to check your schema markup and crawler access.

Week two: Enable agentic storefronts if you're on Shopify. Go to Settings > Sales Channels > Agentic Storefronts and toggle direct checkout on for Copilot and Google. For ChatGPT, if you sell to US buyers, you're already discoverable by default.

Week three: Set up Knowledge Base to control what AI agents say about your brand. Upload return policies, shipping information, FAQs, and brand voice guidelines.

Week four: Start monitoring your AI visibility. Search for your products in ChatGPT, Gemini, Perplexity, and Copilot the way a customer would. If your products don't appear, revisit your product data completeness.

You don't need to be an AI expert to get started. You just need to start.
