OpenAI is finally opening up ChatGPT to advertising, testing ads on free and Go tier users starting this week. The move marks a critical moment for the company, which has raised $64 billion but struggles to convert its 800 million weekly active users into revenue. CEO of Applications Fidji Simo promises ads won't influence ChatGPT's answers or expose user data, but the tension between monetization and user trust is already visible.
The inevitability just became reality. OpenAI announced Friday it's testing ads directly inside ChatGPT, turning one of the internet's most trusted AI tools into an advertising platform. The US rollout begins this week, hitting free-tier users and the newly available $8-a-month Go subscription, while the company's premium subscribers get to skip the whole ad experience.
Here's how it'll work: you ask ChatGPT something - say, help planning a trip to New York - and you get your answer in full. Below that, in a clearly labeled box, you might see a hotel ad. It's contextual placement tied to what you asked about, not some creepy algorithmic inference about your browsing history. That's the promise, anyway.
"People trust ChatGPT for many important and personal tasks, so as we introduce ads, it's crucial we preserve what makes ChatGPT valuable in the first place," Fidji Simo, OpenAI's CEO of applications, wrote in the announcement. "That means you need to trust that ChatGPT's responses are driven by what's objectively useful, never by advertising."
This is where OpenAI's walking a tightrope. The company is explicitly saying it won't do what Meta, Google, and most of the internet advertising ecosystem does by default: sell your data to advertisers. Advertisers won't see your age, location, conversation history, or interests. Instead, they'll only get aggregate metrics - how many times their ad was shown, how many clicks it got. The system will match your conversation topics to relevant ads, using some personalization data, but users can turn that off.
The context matters here. ChatGPT has become a juggernaut with more than 800 million weekly active users, the vast majority of whom pay nothing. Meanwhile, OpenAI's balance sheet tells a different story: the company has raised roughly $64 billion from investors but generated only a fraction of that in annual revenue. With competition heating up from Google's Gemini and other challengers, the pressure to monetize that massive user base wasn't subtle anymore - it was urgent.
OpenAI is being thoughtful about guardrails, at least on paper. Ads won't appear during conversations about health, mental health, or politics. The company also won't serve ads to users it believes are under 18, either because they said so or because of an age-prediction model OpenAI is rolling out. There's an implicit acknowledgment here that ads in certain contexts would cross a line.
