ChatGPT ads spotted and they are quite aggressive

OpenAI is serving ads inside ChatGPT, and new findings suggest the experience looks quite different from what the company originally envisioned.

What’s happening. Research from AI ad intelligence firm Adthena has identified the first confirmed ads appearing on ChatGPT for signed-in desktop users in the U.S.

The big surprise. Early speculation suggested ads would only surface after extended back-and-forth conversations. That’s not what’s happening. When a user asked “What’s the best way to book a weekend away?”, sponsored placements appeared immediately — on the very first response.

What they look like. The ads feature a prominent brand favicon and a clear “Sponsored” label, a design that differs slightly from the concepts OpenAI had previously shared publicly.

Why we care. ChatGPT is one of the most visited sites on the internet. Ads appearing in its responses marks a significant moment for the future of AI monetization — and a potential shift in how brands reach consumers at the point of inquiry.

Between the lines. The immediacy of the ad trigger suggests OpenAI is treating single, high-intent prompts — not just sustained conversations — as viable ad inventory. That’s a meaningful strategic signal for advertisers evaluating where to place budget.

The bottom line. ChatGPT’s ad era has quietly begun. For marketers, the question is no longer if they need an AI search strategy — it’s whether they’re already late.

First spotted. CMO of Adthna, Ashley Fletcher shared his team spotting the ads on LinkedIn.
