For years the question of how OpenAI would make money was largely theoretical. Subscriptions to ChatGPT Plus, API usage and enterprise deals cover a lot of ground, but the costs of training and running frontier AI models are enormous. Advertising inside ChatGPT is the company's first clear attempt to build a media-like revenue engine at the point where users already spend their time.
The platform, accessible through a self-serve manager, lets businesses create campaigns and place ads that appear below relevant conversations. The ads are labelled and kept separate from ChatGPT's own answers, a design choice intended to avoid the kind of confusion that would arise if an advertisement were hard to distinguish from the model's response. The United Kingdom became the first European market where ChatGPT advertising officially launched, signalling an early push toward international expansion.
The move matters because it reframes what ChatGPT is. It is no longer just a research assistant or a productivity tool. By monetizing attention and intent — the user's question, phrased in their own words — OpenAI positions itself next to search engines and social platforms rather than pure software vendors. The question for advertisers is straightforward: does a question typed to an AI carry as much commercial intent as a search query typed to Google?
Not everyone is comfortable with the direction. Rival companies and some user communities have drawn hard lines against ads in AI conversations, and compliance-sensitive sectors such as pharmaceuticals face a new blind spot when regulated advertising enters an interactive channel.
Knowledge takeaway: Advertising in ChatGPT turns natural-language queries — high-intent, user-authored, and context-rich — into a new kind of ad inventory. The long-term test is whether users accept sponsored results inside a tool they trust for answers.
