OpenAI has opened self-serve ads inside ChatGPT, and the front door to a purchase decision is moving from Google's blue links to a single machine answer. Australian businesses are walking into this shift with the weakest part of their marketing, measurement, and paying to sit at the bottom of an answer is not the same as being the answer.
The click used to be the handover. Now the decision gets made inside the answer, and the click is an afterthought you have to pay for.
The Take: ChatGPT ads are not a new advertising channel to slot into the media plan. They are the moment the answer itself became the product, and the front door to a purchase decision quietly moved from a page of blue links to a single machine reply most Australian businesses cannot see inside. Paying to sit at the bottom of that answer is not the same as being the answer.
What actually changed on 22 July?
OpenAI opened a self-serve Ads Manager on 22 July 2026, putting Sponsored text ads at the bottom of ChatGPT answers for Free and Go plan users. Reported CPMs landed near US$30.
The mechanics matter less than the framing. OpenAI set out its approach to advertising as contextual text ads, clearly labelled Sponsored, shown only to Free and Go users and not to accounts under 18. In its testing note, OpenAI confirmed the ads run on context hints, meaning topics an advertiser describes plus the user's live conversation, not the keyword auction every marketer spent a decade learning. Early advertisers include Best Buy, Lowe's and VistaPrint.
Read that setup again. There is no rank to climb, no query to bid on, no ten blue links to fight through. There is one answer, and now a paid slot beneath it.
Why this is bigger than a text ad
For twenty years the deal was simple. You optimised a page, Google ranked it, a person clicked through to your site and you got a shot at converting them. The click was the handover. It was measurable, it was yours and it was the thing every SEO budget in the country was built to earn.
The answer engine breaks the handover. When someone asks ChatGPT which accounting software suits a sole trader, or who fixes ducted heating in Geelong, the model composes a reply from sources the user never visits. The reasoning, the comparison and increasingly the recommendation happen before anyone reaches your website. The ad slot OpenAI just switched on sits inside that moment, not before it.
This is the part Australian owners keep underrating. The ad is downstream. The disintermediation is upstream, and it is already happening whether you buy a slot or not.
The money is already moving
None of this is theoretical spend. Australia's advertising market grew 5.2% to A$28.9 billion in 2025, and WPP Media forecasts it will reach A$31.1 billion in 2026, up 7.4%. Retail media, the last format to redraw where attention gets sold, is the fastest-growing channel of the lot.
Retail media took years to become a A$2.3 billion line item by owning the moment of intent on someone else's platform. Answer ads own an earlier moment, the moment the decision is formed. The pattern is not new. The speed is.
The audience is here already. 12% of Australians now name AI tools as their main way to find information online, up from 5% a year earlier, while about 64% have already seen an AI Overview sitting above Google's results. Roy Morgan puts ChatGPT usage at 10.5 million Australians.

Can you even tell if an AI answer sent you a customer?
Here is where the confidence drains out of most rooms I sit in. Across the Australian market we have scored, Data and Tracking is routinely the weakest of the six marketing dimensions we measure. It was the softest foundation before any of this. Now it is the foundation the answer economy is landing on.
Think about what measuring this actually requires. An AI answer engine sends a visitor with no referrer you recognise, no campaign tag, no clean line back to the conversation that created them. Most businesses cannot separate that traffic from direct visits today. They cannot tell whether ChatGPT, Gemini or an AI Overview is sending them ten customers a week or none.
Sit with that for a second. The channel reshaping how buying decisions get made is the one channel the average Australian business has no instrument pointed at.
Buying an answer ad on top of that blindness does not fix it. It just adds spend to a system you cannot read.
What I would do about it
Do not rush to the Ads Manager. The slot will still be there when your measurement can actually justify it. Four things come first.
Build referral visibility now. Segment your analytics so AI referrers and unattributed direct traffic are separated and watched, not lumped together. You cannot manage a channel you cannot see, and this one is arriving early.
Become the source, not the buyer. Answer engines quote clear, specific, well-structured content with a real point of view. Publish the comparison, the pricing logic and the honest answer to the question your buyers actually ask. That is how you get cited inside the answer rather than renting a line under it.
Fix the fundamentals the answer will judge you on. When a model summarises your business, it reads your reviews, your structured data and your clarity of positioning. Weak signals produce a weak summary you never get to edit.
Only then consider paid placement, with a number you can defend. A US$30 CPM is a real cost against a channel most businesses cannot yet attribute a single sale to.
How we score this
New Rebellion scores Australian businesses across six marketing dimensions, and Data and Tracking sits consistently among the lowest. These are directional observations drawn across the market we have scored rather than a single audited sample, and the full scoring methodology is public.
The bottom line
My view, stated plainly, is that the businesses who win the answer economy will not be the ones who bought the first ads. They will be the ones who could measure whether the answer was working, because they fixed their foundations while the rest of the market reached for the buy button. The ad slot is the easy part. Being the answer, and knowing when you are, is the hard part you cannot buy your way out of.
If you cannot yet tell whether AI answers are sending you customers, start there. See where your marketing actually stands with New Rebellion Hub.
Frequently asked questions
What are ChatGPT ads?
They are contextual text ads OpenAI began selling through a self-serve Ads Manager on 22 July 2026. They appear labelled Sponsored at the bottom of ChatGPT answers for Free and Go plan users, target on conversation context rather than keyword bids and are not shown to accounts under 18.
Are ChatGPT ads available to Australian businesses?
The Ads Manager is self-serve, so Australian advertisers can access it, though early named advertisers were large US retailers. Before buying, the harder question for an Australian business is whether it can measure any return, given how few can currently attribute traffic from AI answer engines.
Will AI answers replace Google search for my business?
Not overnight, but the trend is clear. 12% of Australians already name AI tools as their main way to find information and about 64% have seen an AI Overview above Google's results, so a meaningful share of buying decisions now forms inside an answer before anyone reaches your website.
How do I know if AI is sending me customers?
Most businesses cannot tell yet, because AI referral traffic often arrives without clean attribution and gets counted as direct. The first step is segmenting your analytics to isolate AI referrers, then improving the content and structured data that answer engines quote from.
