Who's live in AI
checkout? The 2026
tracker.

Every few weeks a founder forwards me a screenshot of their product sitting inside ChatGPT or Perplexity and asks the same thing: can people actually buy this here, or is it just showing up? It is a fair question, because the answer has changed twice in the last nine months, and most of the coverage online is either a launch-day press release or a panic thread. Neither tells you the current state of play.

So this is the tracker I wish existed. A maintained directory of which retailers are genuinely live in AI and agentic checkout, on which platform, using which rails, and since when, with a source for every line. It is deliberately literal. No predictions about where this all goes in three years, just who you can buy from today and how the transaction actually works. I will keep the framing simple and date everything, because in this corner of commerce a fact goes stale in a month.

One note on how I built this. For each entry I anchor to the origin primary source, the official company announcement, the SEC filing, or the investor-relations release where the integration was first disclosed, and I treat trade-press coverage as secondary corroboration layered on top. So for public companies like Walmart, PayPal, Alphabet, and Amazon you will see the newsroom, IR, or 8-K link next to the reporting. Where a status is my read of the situation rather than a stated fact, I say so. Treat this as a snapshot with a date stamp on it, not a permanent record. I update the framing here as the platforms move, and they move often.

The master directory
of who's live in AI
checkout.

Here is the single table most people come for: the most notable named integrations across the major assistants, each with the surface it runs on, how checkout actually works, when it went live, and the source. Read the status word first (the next section defines what each one means), then the "how it works" cell, because those two together tell you whether a shopper can genuinely buy from that retailer inside that assistant today.

The one row that surprises people every time is Perplexity. The assistant with the smallest shopping profile is the one running the deepest in-chat checkout in July 2026, because it borrowed PayPal's existing merchant network instead of trying to rebuild commerce from scratch the way OpenAI did. That is the lesson of the table: the winners plugged into rails that already worked.

How to read the
status column in
this tracker.

The directory above leans on four status words, because "live in AI checkout" gets used to mean four very different things and the distinction decides whether a listing is worth anything to you. Every row in the directory carries one of these four states, and here is exactly what each one means. When you scan the directory, the status word is the thing to read first.

Live, in-chat. The shopper completes the whole purchase inside the assistant and never leaves it. The platform effectively becomes the checkout, and the brand often sees the order only after it closes. Perplexity Instant Buy is the clearest working example in July 2026. This is the model brands are most nervous about, because it puts the platform between you and your customer.

Live, rerouting. The assistant does the discovery and the hand-raise, then sends the shopper to the brand's own site to finish the purchase. Google's Buy for Me and Amazon's Buy for Me both work this way. This is the model quietly winning in 2026, and it is the friendlier one for brands because you keep the checkout, the customer data, and the post-sale relationship.

Sunset. The integration was live and has been discontinued. ChatGPT Instant Checkout is the marquee example: real merchants integrated, then the feature was pulled around March 5, 2026. A sunset row is a warning label, a reminder that building your operation around a single platform feature is a bet on that feature surviving.

Building or announced. A partnership or app has been confirmed but is not broadly available to shoppers yet. The ChatGPT retailer apps from Target, Sephora, Nordstrom, and others sit here as of July 2026. Announced is not the same as buyable, and the gap between the two has been measured in quarters, not weeks, throughout this cycle.

ChatGPT: launched,
struggled, and pivoted
to retailer apps.

OpenAI's arc is the most instructive one in the directory, because it is the only major player that tried the hardest version of AI checkout, completing the purchase inside the chat, and it is the one that retreated. The timeline is worth laying out cleanly, because the dates tell the story better than any narrative.

The launch was real and the partners were real. US Etsy sellers went live in-chat on day one, and OpenAI named Glossier, SKIMS, Spanx, and Vuori among the Shopify brands slated to follow, per the launch coverage. The technology was open-sourced as the Agentic Commerce Protocol, co-developed with Stripe, which was a genuinely smart move to invite the ecosystem in. On paper it was the most ambitious agentic-checkout launch anyone had attempted.

The problem was operational, not conceptual. Instant Checkout struggled with real-time inventory and pricing, it surfaced stale product data that caused failed orders, and it had no clean answer for collecting and remitting US state sales taxes. Onboarding a merchant was slow and manual. Six months in, product selection was still thin and error-prone, which is how a feature launched with a million-merchant promise ended with about 30 Shopify stores live. None of this means agentic checkout is a bad idea. It means checkout is a hard, boring, regulated system, and a chat interface does not make the hard parts disappear.

The pivot is the interesting part for brands. Rather than fix in-chat checkout, OpenAI is handing the surface back to retailers as dedicated apps inside ChatGPT, which give the retailer more control of the look, the data, and the moment they meet the shopper. Etsy confirmed it is building one. Walmart went a step further and plugged its own Sparky assistant into ChatGPT rather than use OpenAI's checkout at all, per reporting on the update. For a brand, the app model is more work than a catalog feed, but it hands you back control of the customer, which is the trade most operators would take.

Perplexity: the in-chat
checkout that is
quietly running.

Perplexity built the working in-chat checkout of 2026, and it did it by not building most of it. On November 25, 2025, PayPal and Perplexity launched Instant Buy, ahead of Black Friday, letting US shoppers complete a purchase inside the Perplexity chat. PayPal supplies the payment rails and the merchant network, and the retailer stays the merchant of record, which is the detail that matters most, per the PayPal announcement. That is why it works where ChatGPT's version did not.

The mechanism is the point. Because the retailer remains the merchant of record, the awkward parts, tax, fulfillment, refunds, chargebacks, stay where they already worked, inside the retailer's existing PayPal relationship. Perplexity did not try to become the store. It became a very good front door to stores that already had checkout figured out. That is a fundamentally more durable design than treating the assistant as the point of sale, and it is why Instant Buy is still processing purchases while Instant Checkout is a memory.

For a brand, the practical read is that if you already run PayPal, a big part of your Perplexity path may be a configuration exercise rather than a rebuild. The heavier your existing payment and fulfillment stack, the less net-new work these agentic surfaces require, which is the opposite of the "rip everything out for AI" narrative that made the rounds in 2025. The brands that got discoverable fastest were the ones already plugged into the rails the assistants borrowed.

Google AI Mode:
agentic checkout
inside Search.

Google's version lives where the most shopping intent already is, inside Search. In November 2025 Google turned on agentic checkout in AI Mode, branded "Buy for Me," per its Shopping announcement. When a merchant supports Google Pay and the checkout flow, the shopper taps Buy for Me and Google adds the item to the cart and completes the purchase on the retailer's own site. It is the rerouting model, executed at the scale of Search.

Google's advantage is distribution and its own protocol. It named Wayfair, Chewy, Quince, and select Shopify merchants as eligible at launch, and it published the Universal Commerce Protocol in January 2026 to let an agent handle discount codes, loyalty credentials, and selling terms alongside Google Pay, per its retailer tooling announcement. Walmart, which walked away from OpenAI's checkout, plugged into Google's discovery flow in January 2026. If you want to understand how UCP differs from OpenAI's ACP and why the protocol war matters, I compared them in the UCP versus ACP breakdown.

The strategic read is that Google routes agentic checkout through Google Pay and the retailer's own site, rather than trying to hold the transaction itself. That is the same merchant-of-record logic that made Perplexity's flow durable, and it is a signal about where this whole market is settling: the assistants that will last are the ones that route to the store, not the ones that try to replace it.

Amazon: the walled
garden that skipped the
assistants entirely.

Amazon is in the directory, but on its own terms. It never joined ChatGPT or Perplexity. Instead it built agentic shopping inside its own app, through the Rufus assistant, and it blocked outside agents from crawling its catalog. That is a deliberate walled-garden strategy, and given Amazon's scale it is a viable one in a way it would not be for anyone else. I covered the standoff when it broke in Amazon blocking OpenAI's catalog access.

The numbers explain the confidence. Amazon disclosed that Rufus reached more than 300 million customers by the end of 2025 and was on roughly a $12 billion incremental annualized sales run-rate, per Amazon's own figures. Its Buy for Me feature, launched in April 2025 on Amazon Nova and Anthropic Claude, will buy an item from a brand's own site when Amazon does not stock it, and it grew from about 65,000 SKUs at launch to more than 500,000 by late 2025. Amazon does not need a third-party assistant, because it already has the largest shopping assistant most Americans use.

For a brand, the takeaway is that Amazon remains a separate game with separate rules. You will not reach an Amazon shopper through ChatGPT or Perplexity, you reach them through Rufus, through your Amazon listing, or through Buy for Me pointing at your own storefront. If a meaningful share of your demand lives on Amazon, treat it as its own agentic channel, not as something the ChatGPT or Google directories cover.

The rails and protocols
underneath every
AI checkout.

Under every row in the directory is a payment rail and a protocol, and they matter because they decide how much work an integration takes and who controls the transaction. The same pattern shows up here: the assistants that borrowed a working rail shipped durable checkout, and the one that tried to own the rail stumbled. Here is the layer beneath the assistants.

The card networks are the quiet story here. Mastercard became the first major network to enable all of its US cardholders for agent-initiated payments, with a full US rollout in November 2025 built on scoped Agentic Tokens, and Visa's Intelligent Commerce reached production around the same window, per reporting on the networks' agentic moves. That plumbing is what makes any of the assistant-level checkout legal and safe to run at scale, and I dug into the payment side in how Visa and OpenAI wired agentic payments. For a broader map of how these pieces fit together for a Shopify brand, the pillar is agentic commerce for Shopify brands.

The state of AI
checkout, as of
July 2026.

Start with the reversal, because it reframes everything. ChatGPT was the first big assistant to let you buy in-chat, and it is now the one that walked it back. OpenAI announced Instant Checkout on September 29, 2025, launching first with US Etsy sellers and promising over a million Shopify merchants to follow, per its own launch announcement. Roughly six months later it pulled the feature. As of the sunset, only about 30 Shopify merchants had ever gone live, according to CNBC's reporting on the revamp. That is the full arc, and I wrote the post-mortem on why it happened in what happened to ChatGPT Instant Checkout.

While ChatGPT was struggling, two other players shipped checkout that is still live. Perplexity launched Instant Buy with PayPal on November 25, 2025, and it processes real purchases inside the chat today. Google turned on agentic checkout in AI Mode in November 2025 and kept expanding it into 2026. So the honest ranking of who can actually complete a sale inside an assistant right now runs Perplexity and Google first, Amazon in its own lane, and ChatGPT in transition. That is close to the opposite of what most brands assume.

The deeper pattern under the directory is a shift in where the transaction happens. The first wave, led by ChatGPT Instant Checkout, tried to complete the purchase inside the assistant, with the platform as the point of sale. That model broke on the boring things: real-time inventory, accurate pricing, and US sales-tax collection. The second wave, which is winning, reroutes the shopper to the brand's own site to finish. Google's Buy for Me completes on the retailer's site. Amazon's Buy for Me sends you to the brand. Even Walmart, after abandoning OpenAI's checkout, plugged its own Sparky assistant into ChatGPT and Gemini to route shoppers back to Walmart. I unpacked why that rerouting model is the better deal for brands in OpenAI's second swing at shopping.

There is a discovery layer sitting above all of this that matters just as much as checkout. In March 2026 Shopify auto-enrolled every merchant catalog into its agentic-commerce network, with no opt-in, which means your products are now surfaced across ChatGPT, Copilot, Google AI Mode, Perplexity, and the Shop app whether or not you did anything. Being surfaced and being buyable are different states, and being buyable is not the same as being chosen. I walk through how to check where you actually stand in whether your products are winning or invisible in AI shopping.

What this directory
means for your
brand right now.

Strip away the platform drama and a brand's job in July 2026 is narrower than it sounds. You do not need to chase every assistant, you need to be discoverable everywhere, buyable where it is easy, and in control of the customer wherever possible. The directory above is really a to-do list once you read it that way.

First, get discoverable, because that layer is already live whether you engaged with it or not. Shopify auto-enrolled catalogs into agentic surfaces in March 2026, so the question is no longer whether you are listed but whether you are chosen when an assistant compares you to three competitors. That comes down to clean, structured product data, honest reviews, and the kind of specifics an assistant can quote. It is closer to SEO than to a checkout project, and it is the highest-leverage work available right now.

Second, favor the rerouting surfaces, because they are both winning and better for you. Google's Buy for Me and Amazon's Buy for Me send the shopper to your site, where you keep the checkout, the data, and the after-sale relationship. If you already run PayPal, Perplexity's in-chat flow is largely a configuration task rather than a rebuild. The heavy lift the headlines warned about mostly is not there if your payment and fulfillment stack is already solid.

Third, do not rebuild your operation around any single platform feature. The clearest lesson in this whole directory is the ChatGPT sunset: the merchants who reorganized around Instant Checkout lost six months when it was pulled, while the ones who invested in owning their storefront and catalog came out fine and simply appeared on the next surface. Build for the durable layer, your own site and your product data, and let the assistants come and go around it.

The map as of July 2026 is not the one the hype drew. ChatGPT, the assistant everyone points to, pulled its checkout and is rebuilding as retailer apps. Perplexity and Google are the ones quietly completing real purchases, both by borrowing rails that already worked. Amazon runs its own walled version at a scale nobody else can match. And underneath all of it, the model that is winning is the humble one: route the shopper to the brand's own store and let the brand keep the customer. I will keep this tracker current as the surfaces move, because in this part of commerce, the only safe assumption is that today's snapshot expires soon.

If you are not sure whether an AI assistant can even find your products, that is the thing to fix before you worry about which checkout to chase. Being invisible on the discovery layer makes every checkout debate moot.

This tracker is maintained and updated monthly at a minimum, and more often as new AI-checkout intel lands, sometimes several times a day. It was last updated July 9, 2026. The snapshot here reflects the assistants as of July 9, 2026; as surfaces launch, sunset, or change rails, the rows and status words move with them. Every row is anchored to an origin primary source, the official company announcement, SEC filing, or IR release where the integration was disclosed, with trade press cited as secondary corroboration. If an integration is missing, it either closed after the last update or its terms were never sourced, not that it did not matter.
