AI shopping agents in the next 6 months (Nov 2026 to May 2027)

Google's Universal Cart rolled out in the United States on October 15, 2026, in Search and in the Gemini app. The cart holds items from more than one store. Google says it sits on the Shopping Graph, “60+ billion continually refreshed product listings,” and can notify a shopper about a price drop or a restock. Checkout can use Google Pay in the cart, or the items can move to the merchant's cart. The post names Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and many Shopify merchants. The merchant remains the seller of record.

On November 4, 2026, Google Canada said direct checkout powered by the Universal Commerce Protocol was rolling out to Canadian shoppers on AI Mode in Search and in the Gemini app. The named participants are lululemon, select Shopify merchants, Shoppers Drug Mart, and Simons. Payment uses Google Pay and shipping details saved in Google Wallet. Retailers remain the seller of record. The post says Google's research found that 59 percent of holiday shoppers in Canada plan to use an AI tool to help them shop this season. The post does not print the sample size, the question wording, or the fieldwork dates.

On January 11, 2026, Google said it was launching that protocol with Shopify, Etsy, Wayfair, Target, and Walmart, and that more than 20 other companies endorsed it, including Adyen, American Express, Best Buy, Flipkart, Macy's Inc., Mastercard, Stripe, The Home Depot, Visa, and Zalando. The same post said U.S. checkout would use Google Pay, and that shoppers would soon be able to pay with PayPal. The October 15 and November 4 posts describe Google Pay. They do not say PayPal checkout is live.

Shopify's help page, read November 5, describes its own direct checkout inside Google AI Mode and Gemini. A store has to sell to customers in the United States, Canada, or Australia. Direct checkout is on by default for an eligible store, and it is rolling out gradually to customers in those three countries. The shopper pays with a credit or debit card in a Shopify-powered checkout. Shopify says there is no extra fee beyond ordinary payment processing. The page lists loyalty or rewards blocks among the checkout blocks that might not load there.

OpenAI's merchant page, read November 5, says shopping in ChatGPT is live for users in the United States. Shoppers discover and compare in the chat. They complete the purchase on the merchant's website or app. The page says there are no fees on purchases that start in ChatGPT. Shopify and Etsy catalogs are already integrated. The March 24, 2026 post is the course change: the first Instant Checkout “did not offer the level of flexibility that we aspire to provide,” so merchants would use their own checkout while OpenAI focused on discovery. That post names Target, Sephora, Nordstrom, Lowe's, Best Buy, The Home Depot, and Wayfair as retailers already on the Agentic Commerce Protocol for discovery. It also says a Walmart app inside ChatGPT was available in web browsers, with iOS and Android to follow shortly.

Amazon's October 29 earnings release says Alexa for Shopping was used by 400 million or more customers in the last 12 months, with customer interactions up 570 percent year over year. It also says Amazon added more than 100 capabilities, including gift lists, Subscribe & Save changes, payments and memberships, and new delivery addresses. The guide updated the same day says all U.S. customers can use Alexa for Shopping on the Shopping app and on Amazon.com. Fourth-quarter guidance in the release is net sales of $240.0 billion to $247.0 billion and operating income of $28.5 billion to $33.5 billion. Those ranges are for the company. They do not split out the shopping assistant.

Microsoft's Agentic Commerce page, read November 5, says Copilot Checkout is on Copilot.com and the Copilot mobile app. Eligible merchants are English-language merchants who sell to U.S. buyers, in U.S. dollars. The merchant is the merchant of record. Microsoft says it does not take a commission or affiliate fee on these transactions. A product feed is required. Shopify merchants are described as automatically enrolled, with controls in Shopify admin. PayPal and Stripe are opt-in.

PayPal's November 25, 2025 release says U.S. users could check out inside Perplexity with PayPal, and that the retailer remained the merchant of record. The launch examples are Abercrombie & Fitch, Ashley Furniture, Fabletics, Adorama, and Newegg. That is the launch list.

Adobe's October 29 report, by Vivek Pandya, measures AI traffic as a click from an AI source onto a U.S. retail site. In September 2026 that traffic grew 71 percent year over year. It converted 90 percent better than other traffic. Visitors spent 73 percent more time, viewed 25 percent more pages, and added to the cart at a 53 percent higher rate. Revenue per visit was 83 percent higher. Adobe says the underlying set is more than 1 trillion visits, 100 million SKUs, and 18 product categories. A separate September survey of more than 5,000 U.S. respondents is described as extra context, and it is not the source of those traffic rates. The holiday forecast page, read November 5, says AI-driven traffic grew 127 percent year over year in August 2026, and that holiday traffic is expected to grow 130 percent overall and 141 percent on Thanksgiving.

Google Canada, November 4: “Starting next year, we'll begin broadening access by making simplified UCP integration available directly within Merchant Center.” The same post: “In the coming months, we'll work with retailers to add more capabilities, like applying loyalty rewards.”

The developer guide, last updated October 19, 2026, says the UCP hub “is gradually rolling out in the United States, with Australia and Canada to follow early next year.” Identity linking is labeled coming soon. The capabilities named for a live integration are transfer to the merchant's cart and native checkout on Google. Merchant Center help, read November 5, uses “next year” for Australia and Canada and does not add “early.” It also lists identity linking among capabilities a merchant can select. The developer guide still marks that capability coming soon.

OpenAI's merchant page says, “We're building a merchant platform for self-serve data integration later this year, and plan to expand to more merchants and regions over time.” A second line says OpenAI aims to have a self-service merchant portal later this year. Read on November 5, “later this year” still means the rest of 2026, if the sentence is current. The page does not say November or December. The page, as retrieved, has no visible updated date.

Adobe's October 29 report expects AI traffic to rise 159 percent year over year on Thanksgiving, 95 percent on Black Friday, and 88 percent on Cyber Monday, and it expects the revenue-per-visit advantage to double this holiday season. The holiday page's Thanksgiving figure is 141 percent. The October 29 report's figure is 159 percent. Both numbers are Adobe's. The likely event is a holiday surge in AI-referred visits. The size of the Thanksgiving jump is the gap between those two pages.

Microsoft says Copilot Checkout has “plans to expand to additional surfaces soon.” That is the forward phrase on the page with a short horizon. The country question, on the same page, has no timeline, so it sits under Watch for.

What are AI agents and how do they work? A shopping agent is one of the types of AI agents on this site: a job, not a textbook species. The model reads the request. The harness calls a catalog, a price check, a cart, and, when the product allows it, a payment. Comparing three toasters in a chat is advice. Quoting a live price from a product feed, or paying under a rule the person already set, is the shopping agent.

The payment step is agentic checkout. On the Google, OpenAI, and Microsoft pages checked for this report, the store remains the seller.

OpenAI's feed spec, read November 5, requires nine fields for a discovery row: an item id, a title, a description, a product URL, a brand, a seller name, an image URL, availability, and a price. Availability has to be one of in stock, out of stock, pre-order, backorder, or unknown. Checkout is a separate integration. A flag opts a row in only when checkout is already enabled. The Agentic Commerce Protocol repository, also read November 5, lists a stable OpenAPI folder dated 2026-04-17 and says OpenAI and Stripe maintain the specification.

How to use AI agents, for a purchase, is the permission on the screen in front of you. On Google, a U.S. shopper can save items from more than one store into the Universal Cart and pay with Google Pay at participating stores, or hand the cart to the store. A Canadian shopper on the November 4 rollout can buy from an eligible retailer while still in AI Mode or the Gemini app. Shopify's page says a customer who does not yet have direct checkout is sent to the store to pay.

In ChatGPT, the merchant page says you discover and compare in the chat, then buy on the store's site or app. On Amazon, the October 29 guide separates three grants. A question, a comparison, or a 30-, 90-, or 365-day price history buys nothing. A Scheduled Action can add items to the cart for you to review. Auto-buy at a target price uses the default payment method when the price is reached. The guide's examples are headphones at 30 percent off, or a shirt at $15 or less. Buy for Me, for an eligible product from another store, uses Amazon payment and shipping details after you tap the button. Copilot Checkout, on Microsoft's page, finishes inside Copilot for an eligible U.S. purchase.

The plain-English shelf for the rest of how to use AI agents is Plain English. The shopping shelf is the shopping topic. Product pages in the directory are Alexa for Shopping, ChatGPT, Gemini, and Perplexity, plus the shopping agents category.
