TL;DR
OpenAI says advertising inside ChatGPT reached a $1bn (£790m) annualised run rate in fewer than 200 days, with advertiser numbers now in the tens of thousands. Self-service purchasing through Ads Manager opens across Europe, India, the Middle East and North Africa this week. The company insists ads sit apart from answers and never shape them.
What has actually changed
The mechanics matter more than the milestone. OpenAI’s system reads the conversation you are having and places an ad against it — and, depending on your country and settings, may also draw on your wider history in the product. That is behavioural targeting on a corpus of considerable intimacy: people describe their constraints, their budgets and their reasoning to a chatbot in a way they never did to a search box.
The platform began as a managed-sales operation running through agencies and partners. The shift since is towards self-serve: OpenAI says smaller firms have grown into a meaningful slice of its advertising revenue since Ads Manager arrived in May, and that its partner ecosystem now exceeds 50 technology and measurement firms. Cost-per-click and outcome-optimised bidding account for most campaigns, with a tracking pixel and conversions API underneath.
The commitments, and what they leave out
Three assurances are offered: ads carry a label and sit apart from answers; what ChatGPT says is not swayed by who is paying; and buyers see nothing of anyone’s private conversations. Those are meaningful, and they are also narrower than the worry. Nothing in them addresses whether the presence of a paid slot shapes which products a user ends up considering — a question our coverage of AI recommendation bias keeps running into, most recently in a benchmark showing assistants surface insurance brands in proportions bearing little relation to market share.
The economics deserve attention too. An ad-supported free tier is how OpenAI intends to keep serving over a billion weekly users, which makes advertising structural rather than incidental.
Looking forward
For UK marketers, a new channel with a $1bn run rate and self-serve access is a budget question that arrives this week. For UK publishers, it is something less comfortable: the assistant that already reduces referral traffic now monetises the attention directly. OpenAI says more formats, objectives and buying options are coming, along with “new ways for businesses to interact with consumers in more native ways” — the phrase worth watching, since native is precisely where the labelled-and-separate promise gets tested.
