Since October 13, 2026, any AI agent can take a shopper from search to checkout on Shopify. Through Shop MCP, an agent can search more than a billion products in Shopify Catalog, build a cart and complete a Shop Pay checkout once the shopper confirms the total and payment method. A shopper can skip that step by turning on "Allow agent to pay for me" with a weekly, monthly or total budget. Orders placed this way appear in the merchant's Shopify admin like any other order.
Two in three shoppers who research with AI have already taken an assistant toward checkout, and most of them stopped before it paid. In Product.ai's Trust in AI Commerce Report, published October 14 and fielded from August 27 to September 1, 2026, one in five of the 550 U.S. shoppers who had used AI for product research, 21.6%, said an assistant had completed a purchase for them from start to finish. Another 27.8% reached checkout with an assistant and paid themselves. A further 17.5% started a checkout and stopped before paying, and a third had never started one. It was the first time the survey asked about completed purchases, and the next edition is planned for spring 2027. Product.ai sells a service that tests product claims.
Shoppers who reach a store from an AI assistant have become more likely to buy than other visitors. In Adobe's monthly data, drawn from more than a trillion visits to U.S. retail sites, a visit referred by an AI assistant was about half as likely as other visits to end in a purchase in early 2025. AI-referred visits overtook other visits in September 2025, and in August 2026 they converted 48% more often. On Shopify stores, orders referred by AI assistants grew nearly 13-fold year over year in the first quarter of 2026 and tripled in the second. Organic search still sends Shopify stores more visits than every AI assistant combined, Shopify said.
The shoppers who let an assistant pay are the ones who check it most. Among AI shoppers who buy online, 89.9% had checked an assistant's recommendation through another source before buying, up from 85.7% in Product.ai's June edition, which was fielded in April. Checking was the only measure repeated from that edition to change: the share of online shoppers who used AI for product research held at 42.6% and then 41.5%. Of those who always check, 28.8% had let an assistant complete a purchase, more than three times the 8.8% among those who never check.
Checking catches enough to change the sale. Nine in ten of the shoppers who verify had found an assistant wrong or out of date at least once, and of those, the last time it happened, 26.2% decided not to buy and 22.3% bought a different product. Customer reviews were the first place 36.7% of them looked, ahead of a search engine at 21.9% and the brand's or retailer's own website at 14.0%.
ChatGPT and Gemini are the assistants doing most of the buying. Of the 119 shoppers who had let an assistant complete a purchase, 60.5% named ChatGPT and 47.9% named Gemini, well ahead of Claude at 16.0% and the shopping assistants from Amazon and Walmart at 14.3% each. Shoppers could name more than one, and Product.ai notes that ChatGPT's lead over Gemini is not statistically significant in a group this size. For research, the two were close: 63.5% of AI shoppers used Gemini and 60.0% used ChatGPT.
On Shopify, the setting "Allow Shopify to manage for me" is on by default, which gives AI channels access to a store's products through Shopify Catalog and turns on direct checkout for the relevant channels. In the second quarter, Shopify said, shoppers referred by AI converted about twice as often when the assistant used structured Shopify Catalog data as when it relied on scraped or third-party product feeds. With the setting off, a merchant can set catalog access and direct checkout channel by channel under Sales channels > Agentic in Shopify admin. Products can still be found through ordinary web crawling after catalog access is turned off.
The shopper most likely to let an agent pay for your product is the one who first checks what the agent said, in reviews, in search and on your product page. Ask Gemini and ChatGPT about a product you sell the way a shopper would, then compare the answer with your product page and your listings elsewhere. Wherever a price or specification differs, correct the source the assistant is reading.
Common questions
What did Shopify launch on October 13, 2026?
Shop MCP, a connection that lets any AI agent search the more than a billion products in Shopify Catalog, build a cart and complete a Shop Pay checkout. The shopper confirms the total and payment method, unless they have set a budget with "Allow agent to pay for me."
Are shoppers from AI assistants buying more often than before?
Yes, in Adobe's U.S. retail data. Visits referred by an AI assistant were about half as likely as other visits to end in a purchase in early 2025. They overtook other visits in September 2025 and converted 48% more often in August 2026. On Shopify stores, orders referred by AI assistants tripled year over year in the second quarter of 2026. In Product.ai's surveys, the share of online shoppers using AI for product research held at about 42% between April and late August 2026.
Which shoppers let AI assistants complete purchases?
The ones who check AI's answers most. In Product.ai's survey, fielded from August 27 to September 1, 2026, 21.6% of U.S. shoppers who had used AI for product research had let an assistant complete a purchase. The figure was 28.8% among those who always verify AI's answers, 18.5% among those who sometimes do and 8.8% among those who never do.
Which AI assistants are shoppers letting buy for them?
Mostly ChatGPT and Gemini. Of the 119 shoppers who had let an assistant complete a purchase, 60.5% named ChatGPT and 47.9% named Gemini, and Product.ai notes the gap between the two is not statistically significant. Claude was named by 16.0%.
Can a Shopify merchant control which AI channels reach its catalog?
