Guide to Agentic Storefronts: Selling from Shopify on ChatGPT

Contents

There are moments when the market does not send signals, it sends full-blown sirens playing a long concert, and we have now reached the third act where agentic storefronts have taken the stage and will bring a real shift to the e-commerce world.

Until a few years ago, "buying online" meant opening Amazon, searching for a product, clicking and paying. Then came Google Search, then social ads, then shopping feeds, and finally websites built around your own product catalogue, like Shopify. Every time, those who understood the shift before everyone else gained ground. Those who waited found themselves playing catch-up.

Now an AI chat has become the new supermarket shelf. And the companies already inside it are not the ones with the highest advertising budget, but the ones that connected to the new channels first.

The concrete signal arrived at the end of March 2026: Shopify announced that millions of merchants can now sell directly to ChatGPT users, with products discovered in the chat and purchases completed without opening a browser. (2) This is also part of a wider advertising move, and the best part is that everything works automatically, so you do not need to do anything to make it work, but you can always improve it.

AI Opens Shop: What Agentic Storefronts Are

An agentic storefront is, simply put, the ability for a conversation with an AI to turn into a purchase. The user chats with the AI about a surprise party, asks for gift ideas or product suggestions, the AI interprets the intent and asks for more details about the guest's preferences or what might be most appropriate, analyses the context, and then shows relevant products. From there, the path to payment begins without going through organic search as we know it.

Shopify called its product Agentic Storefronts, and access is already live on ChatGPT, Microsoft Copilot, Google Search's AI Mode and the Gemini app, all managed from a single control panel in Shopify Admin. (2) For merchants already on Shopify, products are available by default, with no separate integrations and no extra fees beyond the usual processing costs. Shopify also launched a separate plan called the "Agentic plan" for brands that do not use Shopify as their main platform, allowing them to insert their catalogue directly into these AI channels without migrating their entire infrastructure. (2)

Fun fact: Etsy was already integrated into ChatGPT before Shopify, with products purchasable directly in the chat. It all started as a test with a few selected merchants, then OpenAI announced the expansion to "over one million" Shopify sellers. (3)

The problem that many companies have not yet focused on is this: AI does not choose products based on who spends the most on advertising. It chooses based on who has better data, more complete attributes, more reviews and structures that are more readable for automated systems. Those who only optimised their feed for paid campaigns risk not appearing at all in these new contexts.

The most common mistake right now is thinking it is enough to wait for your technology provider to handle everything. The integrations exist, but they need to be activated. And above all they need to be fed with quality data, because an AI that receives generic information returns generic products, which means your competitors.

In short: if your catalogue is not machine-readable, you do not exist in these contexts. It is not a penalty, it is simply absence.

Defining the Scale of the Change

It is not just Shopify moving. The ecosystem around this shift is already quite complex, and the data says something specific.

EMARKETER estimates that in 2026 AI platforms will handle $20.57 billion in retail sales in the United States alone, almost four times the 2025 figures. (4) McKinsey, looking further ahead, projects the global opportunity from virtual agent sales at between 3 and 5 trillion dollars by 2030, with up to 1 trillion dollars in US B2C retail alone. (4)

Behavioural data tells a more immediate story. During Cyber Week 2025, 20% of global orders were influenced by AI and automated agents, according to Salesforce. (4) In the same period, visits to American retail sites coming from AI chatbots grew by 670% compared to the previous year, according to Adobe data. (4) And nearly 48% of consumers said they had used or planned to use AI for holiday shopping. (4)

I know we have already thrown a lot of numbers at you, but there is one piece of data that says everything about purchase intent: someone arriving at an e-commerce site from an AI platform has a 30 times higher probability of buying compared to average organic traffic. (4)

OpenAI, meanwhile, stepped back from Instant Checkout, the feature that was supposed to allow direct purchases inside ChatGPT (as previously tested with Etsy). The reason was given by Gartner analysts interviewed by CNBC, who explained that OpenAI underestimated the technical complexity of enabling transactions and that partner retailers ran into the same difficulties. (3) The model was shifted toward dedicated apps inside the chat that redirect the user to the merchant's site to complete the purchase, keeping the brand at the centre of the process.

Amazon, in the meantime, is building in the opposite direction. Rufus, its shopping assistant integrated into the app, generated approximately $12 billion in annualised incremental sales in 2025 and is available to 300 million active customers. (5) But Amazon has also taken legal action against Perplexity over how it accessed its products in "agent" mode, and has built one of the most restrictive agent access policies in the industry. (5) The fence around Rufus, in other words, is high and well-guarded.

The result is that Amazon is playing this game alone, outside open protocols like UCP (Universal Commerce Protocol), developed by Google together with Shopify, Etsy, Walmart, Target, Mastercard, Visa and twenty other global partners. (2, 4) Those who do not sell on Amazon, or who also sell elsewhere, now have alternative channels that are more controllable and accessible.

What to Do Now Without Wasting More Months

The starting point is not technical. It is editorial.

First: check whether your products are already present on a platform connected to these AI channels, or whether you can integrate your catalogue through a structured feed. Both ChatGPT and Gemini prioritise clean data, complete attributes and information updated in real time on prices and availability. A disorganised catalogue is not simply shown less: it is often not shown at all. (2)

Second: test how an AI describes you, not how your website describes you. Open ChatGPT or Gemini, ask to buy a product in your category, and see what happens. If you do not appear, look at who does and ask yourself what they are doing differently. The answer almost never has anything to do with the advertising budget.

Third: if you manage advertising campaigns, keep an eye on how Performance Max and Merchant Center campaigns interact with these new channels. The rules for appearing organically in AI are not the same as those for traditional ads. (1)

This is not a problem that resolves itself over time. Shopify has already activated millions of merchants. The brands selling in these channels right now are collecting attribution data, understanding their customers' conversational queries and optimising accordingly. Every month of delay is a month in which someone else accumulates that advantage.

The Most Stressful Thing About E-commerce in 2026

Let us be honest: keeping up with all these changes is exactly as heavy as it sounds. Every six months there is a new integration, a new protocol, a new platform that "will change everything." And every time you have to stop, understand, decide.

The good news is that those who update first do not necessarily have to do more. They have to do the right things before everyone else. And in this case "before everyone else" means now, because the infrastructure is ready and most competitors have not yet fully understood what is happening. Those with clean data and a machine-readable catalogue start with an advantage, regardless of budget size.

That is it. No sales pitch or message telling you we have a magic formula to solve your problems. You study, today more than ever, to anticipate a thousand problems that will become two thousand tomorrow if you do not tackle them yesterday.

Sorry for the headache, but if a chat on the topic sounds interesting, we are always open to hearing new stories and sharing a good migraine together (preferably not only talking about ads).
