OpenAI says the new format will appear during image generation for US users from later this month. It is the second ad slot in a business already running at $1 billion a year.
OpenAI said on October 5, 2026 that it will begin testing a new kind of advertisement in ChatGPT: sponsored product images that appear when a user asks the chatbot to generate a picture. Testing starts later this month in the US with an initial group of advertisers. The ads will be labelled as sponsored and kept separate from the image being made. 137
\nThe company announced the format together with new measurement tools and brand-safety pilots, at the start of Advertising Week New York, where OpenAI executives were due to ask marketers for feedback. 2 That timing shows who the announcement is for. Users will see the ads, but advertisers are the ones being courted.
\nThe real story is not that a tech company found a new place to put an ad. It is that a lab whose chief executive once said he disliked the very idea is now building the full machinery of an advertising platform, one format and one verification partner at a time.
\nOpenAI says the visual format can show product inspiration, product usage, or experiences associated with a service, giving advertisers a more visual way to promote themselves inside ChatGPT. 347 During the test, the ads are primarily limited to consumer verticals: lifestyle and household goods, local services, travel and experiences, and digital products. 7
\nThe guardrails are the familiar ones. OpenAI says the ads do not influence ChatGPT's answers and run on separate systems from the chat model. 1347 Nothing appears for subscribers on the Plus, Pro, Business, Enterprise or Education plans. 15 Advertising policies updated on September 10, 2026 exclude ads from emotionally vulnerable, sensitive or otherwise unsuitable contexts, and from topics including child safety, political content, gambling and tobacco. 7
\nThe scale is large. OpenAI says ChatGPT reaches 1.2 billion people each week, and calls it the world's largest AI-native consumer platform. 347
\nThe company has not yet named the advertisers in the first group or said what the ads will look like on screen. It has also not said when the format will reach beyond the US or beyond image generation.
\nThe measurement half of the announcement may matter more to the business than the new format. Advertisers have complained that ChatGPT offered thin ways to tell whether an ad led to a sale. 2 Proving that an ad works is what keeps advertisers coming back, and OpenAI has clearly understood it.
\nIts answer has several parts. It added conversion-data integrations with Hightouch, Tealium and LiveRamp, which let advertisers feed their own sales records back into the system. It also named 10 attribution partners, including AppsFlyer, Adjust, Branch, Triple Whale and Kochava. An attribution partner is a firm whose job is to link someone seeing or clicking an ad to a purchase or app install that comes later. 3457
\nThen there are the experiments. OpenAI is running early tests with Haus, Measured and WorkMagic that use what the trade calls geo-based incrementality, or geo-lift. The idea is simple. Ads run in some regions and not in comparable others, and the gap in sales between them shows what the ads added beyond purchases that would have happened anyway. 2457 It is the closest thing advertising has to a controlled trial.
\nA third strand is brand suitability. OpenAI launched pilots with DoubleVerify and Integral Ad Science, two firms that check whether ads sit beside content a brand would rather not be near. The pilots run in controlled testing environments, and OpenAI says they do not have access to private user conversations. 2347 That privacy line is the one to hold the company to. A verification firm that cannot see conversations has to judge by some other signal whether an ad is landing somewhere awkward. How well that works is the open question, and OpenAI has not said whether the pilots will produce public findings.
\nOpenAI also published early results from partners. WeightWatchers saw a cost per acquisition, meaning what it pays to win one new customer, 15.3 percent lower than its blended paid-search benchmark. The wellness brand Dose saw 67 percent of its incremental purchases come from net-new customers. And 93 percent of Portland Leather's visitors from ChatGPT Ads were new. 457 Those are numbers chosen by the company and its partners, and they read as best cases. The independent geo-lift results will carry more weight when they appear.
\nOn the buying side, advertisers can pay by impressions, by clicks, or have the system optimise for conversions. OpenAI describes the market as a relevance-weighted, second-price auction. 5 In a second-price auction the winner pays roughly what the next-highest bidder offered, not its own top bid, and here relevance also counts in who wins. Digiday reported that the price per thousand impressions, known as CPM, fell from roughly $60 at the February launch to as low as $25 by April 2026. Minimum spend dropped from $250,000 to $50,000 over the same period. 5 Cheaper entry and falling prices are what a platform does when it wants more advertisers in the room. They also suggest demand was not unlimited at the opening price.
\nIt began in 2024 with a refusal. In May of that year, Sam Altman told a Harvard audience that the combination of ads and AI was "uniquely unsettling," and that he would not like a chatbot response shaped by "how much was who paying here." 6 By October 2024 he was describing advertising as a "last resort" for OpenAI's business model. 68
\nThe resort was not far off. According to financial documents obtained by the Wall Street Journal in November 2025, OpenAI does not expect to be profitable until 2030 and had committed to spend about $1.4 trillion on data centres and chips. 6 At the time of the first ad launch, OpenAI said only about five percent of ChatGPT's 800 million weekly users paid for subscriptions. 6 A company with those commitments and that ratio of payers is under pressure to find another income.
\nThe people changed first. In May 2025 OpenAI named Fidji Simo as its CEO of applications. She had spent a decade at Meta, leading the launch of advertising in Facebook's news feed and later running the Facebook app. 8 By July 2025 Altman was telling The OpenAI Podcast that he was "not totally against" ads, and that he had even bought items from ads on Instagram. 8 A job posting for an ad-platform engineer followed in September 2025. 8
\nThe first ads arrived on February 9, 2026: a text-based sponsored card below chat responses, for US users on the Free and Go tiers. 156 The Go tier costs $8 a month. 6 By August 31 ChatGPT Ads had reached a $1 billion annualised run rate, and the business now operates in more than 60 countries. 5 According to Enders Analysis, OpenAI has projected that ad revenue could reach $2 billion by the end of 2026 and $102 billion by 2030. 5 The second figure is a projection, and it is a very long way from the first.
\nWhat follows is my analysis, not reporting.
\nFirst, the sums explain the speed. A company that has committed to spend $1.4 trillion cannot live on the five percent of users who pay. Ads are a way of earning from the other 95 percent, and the subscription tiers now double as the ad-free premium product. It is the model Meta and Google ran before, applied to a chatbot. That is not a scandal, but it is a long way from "last resort." In 14 months Altman went from "uniquely unsettling" to saying he had bought things from Instagram ads. He has not, in the material before me, said the old worry was wrong. My view is that the arithmetic made the old position very hard to keep, and that the company is now acting on that arithmetic.
\nSecond, the image format is a different thing from the text card. A sponsored link below an answer sits beside a question you asked. Image generation is a creative task the user owns: you are making something of your own, and a product picture beside it intrudes on that in a way a link under a reply does not. Whether users shrug or bristle is an open question. OpenAI's promise that the ad stays separate from the image is the right promise. It is also one users can check with their own eyes, which is more than can be said of the promise about the chat model.
\nThat second promise, that ads do not influence answers and run on separate systems, is the one that touches Altman's old worry. His fear was a chatbot shaped by who was paying. OpenAI's design answer is to keep the ad system apart from the model. But OpenAI has published nothing that lets outsiders verify that ads do not affect answers. We have the company's word and nothing more. As the money grows, so does the incentive to blur the line. That is not an accusation. It is the ordinary pressure on every ad-funded product, and the reason independent scrutiny matters beyond marketing.
\nThird, the limit is room, not will. Digiday cited a comparison from Zeno Group: roughly 2.5 billion daily ChatGPT prompts against Google's 15 billion searches. 2 ChatGPT also carries only one ad slot per answer. A second placement inside image generation helps, but it does not close a gap of that size. I would expect OpenAI to look for more surfaces, and the obvious candidates are products it already runs, such as its ChatGPT Atlas browser and the Sora app.
\nThe first thing is the test itself. When the images start appearing later this month, we will learn who the first advertisers are and how a sponsored image sits beside a user's own creation. The second is the independent results. If the Haus, Measured and WorkMagic experiments show lifts close to the partner-chosen figures, advertisers will pour in. If they show much less, the falling prices of the spring will look like an early warning. The third is the brand-suitability pilots. If DoubleVerify and Integral Ad Science publish what they found, we will finally see where ads actually land.
\nAnd the fourth is the one that appears in no press release: whether users, handed a free tool and a sponsored picture beside it, decide they are the product after all.
