Agentic shopping, and how AI shopping agents choose

The shopper describes what they want. The agent does the rest. How it works today in ChatGPT, Google, Amazon and Perplexity, and what a brand has to do to be the one it picks.

The definition

Agentic shopping is shopping in which an AI agent does the work a person used to do: it researches products, compares them against the shopper's criteria and, more and more often, completes the purchase. The shopper describes the need and approves the result. An AI shopping agent is the software doing that work, whether it lives in ChatGPT, Google Search, the Amazon app or Perplexity.

With agentic shopping, the buyer may never see your homepage. They see whatever the agent decided to show them.

Three jobs an AI shopping agent does

Research. The agent asks what matters, then reads across the web. OpenAI's shopping research feature, launched November 24, 2025, asks clarifying questions about budget and features, draws on past conversations and memory, and returns a personalized buyer's guide in minutes.

Compare. The agent narrows the field. When several merchants sell the same product, OpenAI says ChatGPT weighs availability, price, quality, whether a merchant is the primary seller and whether Instant Checkout is enabled.

Buy. The agent completes the order, or hands the shopper to a merchant who can. This is the newest job and the one changing fastest.

How ChatGPT shopping works today

OpenAI said in September 2025 that more than 700 million people turn to ChatGPT each week, including to find products. That month it launched Instant Checkout, letting US users buy from US Etsy sellers inside the chat, with over a million Shopify merchants announced as coming soon. OpenAI says product results are organic and unsponsored, ranked on relevance to the user.

The merchant side has moved since launch. OpenAI's page for merchants now describes product feeds built on the Agentic Commerce Protocol. It says shoppers are sent to the merchant's site or app by default, and that catalogs from Shopify and Etsy are already integrated with no extra setup. Shopping is live for ChatGPT users in the US. So ChatGPT shopping today is two things: a discovery engine fed by product data, and a checkout that some merchants offer inside the chat.

Google, Amazon, Perplexity and Copilot

Google. In November 2025 Google began rolling out agentic checkout on Search, including AI Mode, with eligible US merchants such as Wayfair, Chewy and Quince. The same update added Let Google Call, where AI phones nearby stores to check stock, price and promotions, powered by Google's Duplex technology.

Amazon. Rufus, Amazon's shopping assistant, is available to all US customers in the Amazon Shopping app and on desktop. Buy for Me goes further. In beta for a subset of US customers, it lets Amazon buy an item from a brand's own website on the customer's behalf when Amazon does not sell it. Amazon says it runs on Amazon Bedrock, with Amazon Nova and Anthropic's Claude models.

Perplexity. On November 25, 2025, PayPal and Perplexity launched Instant Buy, letting US Perplexity users check out in the chat from merchants including Abercrombie & Fitch, Ashley Furniture, Fabletics, Adorama and Newegg.

Microsoft. On January 8, 2026, PayPal announced it was powering Copilot Checkout, so shoppers can discover, decide and pay without leaving Copilot.

Where agentic shopping still falls short

It is early, and the launch notes say so. OpenAI launched Instant Checkout with single item purchases and said multi item carts would come next. Amazon's Buy for Me is a beta for a subset of US customers, starting with a limited number of brand stores. Google describes agentic checkout as rolling out from eligible merchants. Nearly everything above started in the United States.

The volume is already real. Amazon says customers had already asked Rufus tens of millions of questions. OpenAI says hundreds of millions of people use ChatGPT to find, understand and compare products. Buying inside the chat is new. Choosing already happens at scale, and a brand can lose at that step without ever knowing.

How the agent decides who wins

Every platform describes its ranking a little differently. Underneath, they come down to the three tests in Found, Chosen, Booked. Can the agent find accurate facts about the product? Can it trust them, through reviews, consistent data and sources it already believes? Can it complete the purchase or hand off cleanly?

OpenAI says it plainly on its merchant page. It tells merchants that richer data helps products surface with more accurate information when shoppers compare options, and asks them to keep pricing and availability in sync. When your data is missing, the agent has a reason to pick someone else.

What a brand should do this quarter

Get your catalog into the feeds. If you are on Shopify, Agentic Storefronts, announced December 10, 2025, sends products to ChatGPT, Perplexity and Microsoft Copilot from one setup in the admin. PayPal's Store Sync does a similar job for PayPal merchants. If neither applies, apply through OpenAI's merchant page.

Fill every field. Price, stock, variants, dimensions, materials, shipping, returns. An agent comparing three products will not guess what yours is made of.

Publish the answers. The questions shoppers ask an assistant are specific. Will it fit. Does it ship by Friday. Can I return it. Put plain answers where a machine can read them.

Test like a shopper. Ask ChatGPT, Google AI Mode, Rufus and Perplexity the question your customer asks, in your customer's words. Write down who wins. Do it every month, because the answers move.

The payment underneath all of this is covered in agentic payments. The broader category is defined in what is agentic commerce, and if you want someone to run the full audit, start with what an agentic commerce advisor does.
