What just happened
OpenAI launched ChatGPT advertising as a closed pilot on February 9, 2026. The entry price was roughly $60 CPM, a premium OpenAI justified by pointing to ChatGPT's 500 million weekly active users and the "high-intent context" of a conversational interface. People asking questions, getting answers, then seeing a product recommendation. Good intent signal, the pitch went.
By May, those CPMs have settled around $25. A 58% drop in ten weeks. And OpenAI, reading the room, has added CPC bidding at $3–$5 per click and opened the self-serve Ads Manager to all US businesses.
This is worth understanding. Not because the price drop is alarming, but because of what it tells you about what's actually for sale.
Why the premium disappeared
The first advertisers in were brand teams with awareness budgets. New channel, culturally significant platform, first-mover positioning. They paid the premium because they could, and because the narrative was compelling.
Then performance buyers showed up with spreadsheets. At $60 CPM with unverified click rates, limited conversion tracking, and no third-party measurement, the math on customer acquisition cost didn't work for most e-commerce categories. Demand contracted. Ad inventory in ChatGPT responses kept expanding. CPMs followed gravity.
This is the same arc TikTok ran in 2019–2020: sky-high launch CPMs, narrative fatigue, then normalisation to market rates. It doesn't mean the channel is broken. It means it's priced like a real channel now instead of a novelty bet.
The difference from TikTok is that ChatGPT's attribution infrastructure is still catching up. OpenAI has built a conversion pixel that tracks lead creation, order creation, and subscription starts. Useful start. But third-party measurement isn't live yet, and CPA bidding, which would let you optimise directly on cost per acquisition, is still in development with no published timeline.
What $3–$5 CPC actually means
Adding CPC bidding is the move OpenAI had to make. Performance marketers won't buy at $25 CPM on an unknown click-through rate any more than they'd buy display inventory that way. CPC gives you a number to model against.
At $3–$5 per click, ChatGPT sits above Meta social (typically $0.50–$2.00 CPC) and roughly level with mid-competitive Google Search terms. That's not cheap. But the intent profile of someone clicking a ChatGPT sponsored result is different from a social clicker.
That person was actively seeking information. They asked a question, got an answer, and clicked a recommendation inside the response. That's closer to search intent than social browsing, which means your post-click conversion rate needs to be measured against search benchmarks, not social ones. If your landing page is built for browsing rather than deciding, this traffic won't convert at a rate that justifies the CPC.
The self-serve opening
The minimum spend dropped from $250,000 to $50,000. The Ads Manager is now accessible to any US business directly, without holding company intermediaries.
That's a real change. Brands running $50K+ monthly in paid media can now test ChatGPT inventory without an enterprise contract. OpenAI also added StackAdapt for programmatic placement, so if you're already running programmatic buys, ChatGPT inventory may surface in your existing workflow.
The $50K minimum is still a genuine barrier for most DTC brands. Accounts with sub-$50K monthly budgets aren't in a position to run a meaningful test while keeping primary channels funded.
What to do now
For accounts spending over $100K monthly across Google and Meta: request Ads Manager access and plan a 4-week test against a single product or category. Measure with your own pixel alongside OpenAI's conversion tracking. Don't make budget calls based on OpenAI's reported conversions alone before third-party verification is live. Compare the observed CPA against what you'd pay on Google for the same level of intent.
For accounts under $50K monthly: wait. CPA bidding will arrive. Third-party partners will integrate. A test in Q4 2026 with more mature infrastructure will give you more useful signal than one today.
ChatGPT ads are no longer a premium experiment — they're a mid-tier performance channel, and the test is whether your product fits the context.
