ChatGPT Ads: first results are in

The timing isn’t a coincidence. You have to go back to March to understand why OpenAI needed a win like Amazon’s. In September 2025, ChatGPT launched Instant Checkout, the promise of completing a payment without leaving the conversation, with Shopify, Etsy and Walmart as launch partners. Five months later, the results were grim. It was Walmart, in particular, that put out the number that stung: the conversion rate for payments made inside ChatGPT ran at roughly a third of what the same visitor delivered when sent to walmart.com.

OpenAI pulled the plug in early March 2026, rebranding the retreat from built-in checkout as a simple “shift to Apps.” The official statement described a “smoother” buying experience. In practice, the conversation stays in ChatGPT, the transaction goes back to the merchant’s own site, exactly the model of a standard search engine earning a commission per click rather than a cut of the sale.

From there, everything moves in the same direction: ads. The ad pilot launched on February 9, 2026. The self-serve Ads Manager, with click-based bidding, followed on May 5. Automated product feeds arrived on June 2. Advertising is no longer a side feature at OpenAI. After giving up on monetizing the transaction directly, the company turned it into ChatGPT’s main economic engine. Amazon becomes the first major account to validate, under real conditions, the model OpenAI ended up betting everything on.

The mechanism is worth spelling out, because it says a lot about the strategy behind it. Amazon didn’t join OpenAI’s product feed system, the one that lets a structured catalog generate placements automatically based on conversational intent. It simply bought brand visibility: every sponsored click redirects to Amazon.com, never to a payment completed inside the conversation. Amazon keeps control of the transaction, the customer data, and the relationship.

Target is playing a different game. Testing with its ad arm Roundel since February 9, the retailer claims a 40% increase in ChatGPT-driven traffic to its site every month, and in the same move has rolled out a dedicated app inside ChatGPT alongside a partnership with Google on the Universal Commerce Protocol. No blocking on one side and buying on the other: here, organic, agentic and paid all move together. The number measures traffic that predates the ad buys, not ad performance, but the logic runs in the exact opposite direction from Amazon’s.

ChatGPT Ads: who’s already in (overview)

What stands out, beyond the Amazon case, is how fast the format itself is changing. In a LinkedIn post tracking the story closely, Kaziukėnas has already documented three generations of ads in the space of a few months: a first version as a plain text-and-image banner (Guitar Center), a second that widens the image and tightens the horizontal footprint to prepare for showing several ads side by side (Ralph Lauren), and a third where the format starts to resemble an actual product card, complete with an “Ad” label and an options menu (Quince). He also notes that a dedicated shopping module is in the works, while pointing out that OpenAI is still leaning on formats close to standard banners. In his view, Google remains ahead on ad integration genuinely built for AI.

This fast pace tracks the official timeline. OpenAI started testing ads in ChatGPT on February 9, 2026, for US users on the Free and Go plans. On May 5, the platform opened self-serve buying through its Ads Manager, adding click-based bidding on top of the existing CPM, along with a measurement pixel and a Conversions API. Less than a month later, on June 2, product feed management moved into a dedicated section of the Ads Manager, confirmed publicly: advertisers can now connect a structured catalog, up to one million SKUs per advertiser, with a 100-product sample required before the feed opens in full. Same format already sent to Google Shopping, no rebuild needed.

On June 6, 2026, ChatGPT Ads crossed the Atlantic and landed in the UK, the first European market OpenAI has opened, with Dentsu as launch partner and Zalando among the very first brands live, alongside Tesco, Hilton and Hiscox. The $60 CPM listed in the US has settled around $30 in this first European market, and access is still handled case by case by OpenAI’s sales teams, with no self-serve counter like in the US. For a European e-commerce brand, the question that follows is no longer a textbook hypothetical.

Amazon’s behavior is a signal, not a model to copy. Most brands have neither the negotiating leverage nor the strategic interest to block ChatGPT while buying ads on it. For them, the question raised by these first months of ChatGPT Ads is more direct: is the product feed already powering Google Shopping ready to power this new channel too, organic and paid at once. The answer, for 80% of merchants according to the figures cited above, is not yet.

The gap between “I’m visible to AI agents” and “I can actually talk to them” opened up a year ago on organic ground. It has just opened a second time, on paid ground, with ad budget on the line. Brands that already invested in structuring their catalog for Google Shopping have covered a good part of the distance. Others are discovering, with ChatGPT Ads, that a data problem they could put off has become a cash flow problem.
