Agentic commerce, explained for brands

Every e-commerce lead has heard the pitch by now. Shoppers will stop browsing, AI agents will do the buying, and any store that isn't "agent ready" by Black Friday will disappear. Some of that is real. Much of it is a sales deck.

Shopify has called this "the first holiday season of the agentic era." That's a platform's framing, but something did change this year. On Shopify, checkout inside several AI assistants is now switched on by default for eligible stores that sell to the US. Google launched a shopping cart that spans stores. And ChatGPT, the biggest assistant, moved the purchase back to the store's own checkout. So it's a good moment to sort what is live from what is still a demo, and to decide what a brand selling a few million to a hundred million a year should do about it in the weeks before Black Friday.

Agentic commerce in plain words

Agentic commerce is shopping where an AI assistant does part of the work a shopper used to do, from searching and comparing to building a cart and, sometimes, paying. It helps to split it into three levels, because they move at very different speeds.

• The assistant answers. A shopper asks ChatGPT, Gemini or Perplexity for a warm wool coat that isn't black, under $400, and gets a shortlist with links. This is already everyday behavior. In Shopify's survey of 18,000 shoppers in nine countries, five of them in Europe, 65% said they were likely to use AI for at least one shopping task over the holidays.
• The assistant sends. The shopper clicks through and lands on a store's product page, already half decided. This traffic is small and growing fast, as the numbers further down show.
• The assistant buys. The shopper confirms and the assistant checks out without the shopper ever visiting the store. This is live in a few places, almost all of them in the US, and shoppers are wary of it. In the same survey, 29% said they trust AI to make a purchase on their behalf.

Most of the noise is about the third level. For a mid-sized brand, most of what matters this season is in the first two.

What is live, assistant by assistant

Here is where things stand at the end of October.

ChatGPT shows products from stores and sends the shopper to the store's own checkout to pay. OpenAI launched buying inside the chat, called Instant Checkout and built on the Agentic Commerce Protocol it developed with Stripe, in September 2025. In March 2026 it stepped back, letting merchants use their own checkout while it concentrated on helping shoppers find products. Shopify stores that sell to US customers are listed in ChatGPT by default, and since September US Shopify merchants can also buy ads there.

Google lets shoppers in AI Mode and the Gemini app buy without leaving Google, through the Universal Commerce Protocol, an open standard it built with Shopify and large retailers. Since October 15, US shoppers also have Universal Cart, which holds products from several stores in one cart and either pays with Google Pay or hands the cart over to the store's own checkout.

Microsoft Copilot and Meta's new assistant, Muse, can both complete a purchase inside the chat for eligible Shopify stores. Copilot does it for shoppers in the US, Meta for shoppers in the US, Canada, Mexico, Brazil, Japan and Singapore.

Perplexity offers free shopping to US users, with checkout through PayPal inside the answer.

Amazon folded its shopping chatbot into Alexa in May and put the assistant into the search bar, the search results and product pages, alongside its chat window.

In the checkouts above, the store stays the seller of record.

Where does the purchase happen?

ChatGPT, the biggest assistant, moved the purchase back to the merchant's checkout this spring. Walmart, one of the largest sellers in ChatGPT's first checkout, said in March that purchases made inside ChatGPT converted at a third of the rate of shoppers who clicked through to Walmart's own site. That is one retailer and one early design, but it fits the 29% who say they trust AI to buy for them.

Google, Copilot and Meta are pushing the other way. On Shopify, their checkout inside the chat is switched on by default for eligible stores. So for a Shopify brand selling to the US, some sales this season may happen in a chat window the brand didn't design.

For a brand selling mainly in Europe, the picture is simpler. None of these in-chat checkouts is live for shoppers in the EU yet. This season, AI is a source of visits for you, not of sales inside the chat.

Either way, the shopper meets your product data first and, most of the time, your own site second.

Big growth, small numbers

Adobe forecasts that US shoppers will spend $275.1 billion online between November 1 and December 31, up 6.7% on last year, and that visits to retail sites from AI services will rise 130%. Those visitors are worth having. In August, Adobe measured them converting 48% better than other traffic, where a year earlier they converted worse.

They are also still few. In September, AI assistants sent fewer than 2 in every 1,000 of the referral clicks Statcounter tracked, in the US and in Europe alike, while search engines sent close to 9 in 10. AI visits are growing fast and converting well, and they are still a tiny share of the total.

Four things to do before Black Friday

Make your product data easy to read

An assistant can only recommend what it understands, and it learns your products from your product pages and the feeds you already send out, such as Shopify's catalog and Google Merchant Center. A sweater called "The Margaux" with a mood-board description gives it little to work with. "Margaux cashmere-blend crew neck, oatmeal" gives it plenty. Fill in color, material, fit and size as real attributes rather than only in prose, and keep stock accurate. An assistant that recommends a sold-out size sends you a disappointed shopper.

Find out where you already show up

If you're on Shopify, start with the Agentic Storefronts settings. Depending on the countries you sell to, eligible stores are listed in ChatGPT, Copilot, Google's AI Mode and Gemini, and Meta by default, and in Copilot, Google and Meta, buying inside the chat is switched on by default too. You can turn channels off one by one. Read what each channel does with the order before you decide, and decide on purpose rather than by default.

Then shop your category the way your customers do. Ask ChatGPT, Gemini and Perplexity for "a linen shirt for a summer wedding" or "a merino base layer for hiking." Do you appear? Is what they say about you right? Which of your products do they pick, and which page do they link to? Twenty minutes of this is well spent.

Get the landing page ready for a decided shopper

A shopper who arrives from an assistant has done the browsing already. They land deep, often straight on a product page, wanting one specific thing, and they are easy to lose. A sold-out size, a search for "the green one" that comes back empty, a collection page that hides the product they came for, and they go back to the chat and ask for an alternative. Make sure in-stock products lead, that your search understands the words shoppers actually type, typos and synonyms included, and that no search ends on an empty page.

Count AI visits on their own

Most analytics tools already see this traffic as referrals from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com, and ChatGPT usually tags its links with utm_source=chatgpt.com. Group them into one channel and watch it through the season, the visits, the pages they land on, and how they convert next to everything else. Treat the number as a floor, because some AI visits arrive without a tag and show up as direct traffic. For most stores it is small today. It is also the number that will tell you, by January, whether any of this deserves budget.

Leave these for later

• A special version of your store for agents. Assistants read the same pages and feeds your shoppers and Google already use. Clean data and fast pages do more than a separate "agent-ready" build.
• Chasing sales inside the chat. Checkout in the chat is US-only for now, and shoppers are still wary of it. Get the data and the landing pages right first, because they serve both routes.
• A chatbot on every page. When Amazon rebuilt its shopping assistant in May, it put it into the search bar, the search results and product pages, not only a chat window. If you add AI to your store, start where shoppers already look.

What an assistant can't do for your brand

An assistant can describe a coat. It can't make your store the place someone wants to arrive, with the edit, the way a collection tells its story, the product that leads a drop. That is still a person's job, and it matters more when the first impression happens somewhere you don't control.

Getting the landing page ready is the work we do at Depict. Our search, merchandising and recommendations put in-stock products first in your collections, handle typos and synonyms in search, and keep recommendations relevant, automatically, while your team can still pin, boost and bury by hand. The time that frees goes into the part that makes the brand. Book a demo, or see our pricing, which is public.
