You Can Now Buy Ads Inside ChatGPT. I'd Test It.

I was reviewing a client's Google Ads account last Tuesday when they texted me: "Did you see? ChatGPT has ads now."

Pulled it up. Sure enough, OpenAI launched a self-serve Ads Manager on May 5th. Any US business can now sign up, set a budget, and run ads inside ChatGPT conversations.

Not a rumor. Not an enterprise-only beta. It's live, right now.

400 Million People, All Asking Questions

ChatGPT has over 400 million weekly users. Those users aren't scrolling mindlessly through a feed. They're asking questions, researching products, and making decisions in real time.

That makes it a fundamentally different ad environment than Instagram or TikTok. When someone asks ChatGPT "what's the best CRM for a 10-person team," they're in buying mode. A well-placed ad in that moment hits differently than a banner they scroll past.

What the Platform Actually Offers

OpenAI built this like a mature ad platform. CPC (cost-per-click) bidding. Budget and pacing controls. Pixel-based conversion tracking. A Conversions API for measuring purchases, sign-ups, and leads. A full campaign management dashboard.

They also partnered with Adobe, Criteo, Kargo, Pacvue, and StackAdapt on the tech side. Agency groups like Dentsu, Omnicom, Publicis, and WPP are already onboard.

OpenAI is targeting $2.5 billion in ad revenue this year. They're not experimenting. They're committed.

Should You Test It?

If you spend money on Google or Meta ads, yes. Here's my thinking.

The audience is high-intent. People using ChatGPT to research products are further down the funnel than someone scrolling a social feed. That usually means better conversion rates and lower cost per acquisition.

Early platforms also tend to be cheaper. Remember when Facebook ads cost pennies? The same thing plays out every time a new channel opens. Early adopters get favorable pricing before everyone else floods in.

I'd start small. Set aside 5-10% of your monthly ad budget and test a few campaigns. Track CPCs against your existing channels and compare conversion numbers.

The Privacy Angle

OpenAI says they won't share conversations or personal details with advertisers. The targeting is contextual (based on what the user is asking about) rather than behavioral (based on a tracking profile).

That's a selling point if you're in an industry where customers care about data privacy. You can tell them your ads show up based on context, not surveillance.

What I'm Watching

A few things on my radar.

Ad fatigue. If ChatGPT starts feeling like a billboard, users will push back. OpenAI has to balance revenue against user experience, and they haven't proven they can do that yet.

Measurement maturity. Pixel tracking and a Conversions API are solid starts, but the attribution story will take time to prove out. Don't bet your whole budget on early data.

Competition. Google's AI Overviews already show ads. Meta is testing ads in their AI assistant. The "AI search ads" category is about to get crowded.

So What Now

OpenAI just created a new advertising channel that reaches 400 million people in high-intent moments. It costs nothing to set up an account and test it.

If you run ads for your business or your clients, this is worth 30 minutes of your time. The early economics on new platforms almost always favor the people who show up first.
