ChatGPT's ad platform hit $100 million in annualised revenue within six weeks of its US launch, with fewer than 20% of eligible users actually seeing ads. The minimum spend dropped from $250,000 to $50,000. Self-serve access opened in Australia on 16 April 2026. For performance marketers in this market, the channel is live now.
Every few years, a genuinely new advertising channel opens up. Not a new campaign type inside an existing platform. An entirely new place where attention lives and paid inventory has not been built yet.
ChatGPT Ads is that channel right now. And unlike the early days of most new ad platforms, this one came in with strong performance signals from the start.
$100 million in annualised revenue inside six weeks. CPMs settling between $15 and $40 depending on category. A user base increasingly replacing traditional search for high-intent research queries. And as of 16 April 2026, the platform opened to Australian advertisers via self-serve access. Source: Search Engine Land, April 2026.
What Is the ChatGPT Ad Platform, Exactly?
OpenAI launched advertising inside ChatGPT for Free and Go tier users in the US earlier in 2026. The ads appear in response to relevant queries, integrated with the AI's conversational response rather than appearing as traditional banner or search ads.
Key mechanics:
- Ads are shown to Free and Go tier users. Paid subscribers (Plus and above) do not see ads.
- Placement is contextual and query-triggered, not display-based.
- Fewer than 7% of ads are rated "low relevance" by users, according to OpenAI data.
- CPMs launched around $60 and have settled to $15 to $40 depending on vertical and targeting.
- The managed pilot had 600+ advertisers. Self-serve lowered the minimum spend from $250,000 to $50,000.
Australia, Canada, and New Zealand were added on 16 and 17 April 2026. This is the first time the platform is accessible to Australian advertisers without a managed deal.
Who Should Consider Testing ChatGPT Ads?
The user base using ChatGPT for search-replacement queries is a specific type of buyer. They are researching, comparing, or trying to resolve a problem. They tend to have higher intent than users scrolling a social feed, and they are typically earlier in the buying process than someone searching a specific product query on Google.
The profile of categories where early ad performance has been strongest:
- B2B software and tools, where buyers are actively researching category options
- High-consideration consumer products with a real research phase: finance, health, and education
- Services businesses that benefit from brand presence during evaluation
- Platforms and products that marketers and operators use, given ChatGPT's audience skews tech and knowledge-work
If you sell impulse-purchase consumer goods with low consideration, this is probably not your first testing priority. The strength of the channel is capturing intent during research, not driving impulsive action.
How Do ChatGPT Ads Fit Into a Performance Marketing Mix?
Think of ChatGPT Ads as a complement to existing paid search and social, not a replacement. The user behaviour is different. The intent signal is different. And the ad format is different enough that creative built for Meta or Google does not translate directly.
Where it fits best in the mix right now:
Upper-funnel brand presence during research
A user asking ChatGPT "what is the best project management tool for a small team" is actively in research mode. If your brand appears contextually in that response, you are getting exposure at a high-intent moment without competing in a keyword auction. This is awareness with intent signal, a better combination than most display channels offer.
Category framing for new or complex products
If your product is in a category that people do not know well enough to search for directly, AI search is where they go to get oriented. Being present in that orientation phase is brand-building with conversion potential built in.
Retargeting the research phase
If you are running audience capture alongside ChatGPT ad exposure, users who engaged with your brand in an AI search context and then visit your site can be retargeted through Google and Meta campaigns later in the funnel. The ChatGPT touchpoint seeds the later conversion.
What Do You Need to Get Started?
At $50,000 minimum spend, this is not a test-with-$500 channel. The floor is set at a level that requires meaningful commitment before you see results.
For the creative side, ad content needs to work in a conversational context. It is not a banner. It is not a search ad with a headline and two description lines. The format is designed to feel relevant to the conversation the user is already having. Think about how your brand message would land as a relevant suggestion inside a thoughtful AI answer, not as an interruption to it.
For the broader picture of how AI search channels are changing where buyers research and what they click on, the LLM traffic conversion data breaks down the full picture including what organic AI traffic looks like before you add paid inventory on top of it.
What Are the Risks of Getting in Early?
Any new ad platform at this stage carries measurement risk. Attribution models are still maturing. Audience data is less rich than established platforms. The ad format is new enough that best practices are still being written.
The standard early-mover tradeoffs apply. You get better CPMs before competition drives them up. You get to learn the platform before everyone else does. You also carry the cost of that learning curve and the uncertainty around what good performance looks like before there is enough industry data to benchmark against.
The approach that reduces that risk: treat the first 90 days as a learning budget, not a performance budget. Set separate KPIs for the learning phase, focus on gathering data about which creative approaches and audience types respond, and do not hold the channel to the same conversion benchmarks as a mature platform like Google Search.
Frequently Asked Questions
Are ChatGPT Ads available in Australia?
Yes. ChatGPT Ads opened to Australian advertisers via self-serve access on 16 April 2026. International expansion included Australia, Canada, and New Zealand simultaneously, making this the first time the platform is accessible without a managed deal for Australian advertisers.
What is the minimum spend for ChatGPT Ads?
The minimum spend threshold dropped from $250,000 to $50,000 when self-serve access opened. This is a significant reduction but still represents a meaningful commitment compared to most self-serve ad platforms.
What type of ad appears in ChatGPT?
Ads are contextual and appear in response to relevant user queries, integrated into the ChatGPT response format rather than appearing as traditional banners. The format is designed to feel relevant to the conversation. User relevance ratings show fewer than 7% of ads are marked low relevance.
Who sees ChatGPT Ads?
Ads are shown to Free and Go tier users. Paid subscribers (ChatGPT Plus and above) do not see advertising. The free tier has hundreds of millions of users globally, making the addressable audience large despite the premium subscriber exclusion.
How do ChatGPT Ads compare to Google Search Ads?
The intent signal is different. Google Search captures users at the moment they express a specific query. ChatGPT Ads capture users in a research and exploration phase, typically earlier in the buying process. The CPM model versus keyword bidding also creates a different cost structure. Both serve high-intent audiences, but at different funnel stages and with different creative requirements.
