Summary

38.2% of shopping-intent ChatGPT answers carried sponsored ads in June 2026. Here's how to monitor which competitors are buying them, manually or with GEOly's GEM, and what to do with the data.

In June 2026, 38.2% of shopping-intent ChatGPT answers carried a sponsored ad placement — 178,878 of the 467,805 answers in GEOly's US industry monitoring. That number should change how you think about competitive research. Your competitors are no longer just outranking you in ChatGPT's organic product cards; they can now buy their way into the same answers, often directly above you.

If you're asking how to monitor competitors' ChatGPT ads, there are exactly two options. The manual route: run the shopping prompts that matter in your category, look for cards labeled sponsored (each one shows the advertiser's name and domain), and record what you see. The systematic route: use an ads intelligence layer built for this, like GEM — GEOly's Generative Engine Marketing dataset — which runs large panels of shopping prompts on a schedule, detects every sponsored ad card, logs the advertiser behind it, and turns the appearances into weekly time series and category benchmarks.

OpenAI doesn't publish an ads library the way Meta does. There is no official page where you can look up which brands are running ChatGPT ads in your category. The only visibility available is what you observe in the answers themselves, which is why monitoring at scale is the whole game. Here's how to do it, what to track, and what the current advertiser data looks like.

Why ads intelligence matters now, not later

ChatGPT ads run through OpenAI's self-serve ads manager in the US, and the ad cards appear alongside organic product cards inside shopping answers. That placement detail is the strategic problem. If you spent a year earning organic visibility for a prompt like "best cordless drill under $150", a competitor can open the ads manager and buy a sponsored card in that exact answer. Your organic spot doesn't disappear; it gets a paid neighbor above it.

And this is no fringe channel. 3,042 distinct advertisers were active on ChatGPT ads in June 2026 (GEOly industry monitoring, US). Self-serve access means the barrier to entry is a credit card, not an agency relationship. Advertiser count and ad penetration point the same direction: the auction in your category is filling up while you read this.
