OpenAI starts rolling out conversion-optimized ChatGPT ad campaigns to early-access advertisers from 5 June 2026. To qualify you needed conversions wired through a Pixel or the Conversions API by 1 June. The pilot hit US$100 million annualised in six weeks.
A channel you cannot measure is a donation. ChatGPT just started letting you measure it.
OpenAI just turned ChatGPT advertising from an awareness experiment into a performance channel. Conversion-optimized campaigns start rolling out to early-access advertisers from today, 5 June 2026. The catch is the entry ticket. To qualify you needed conversions wired up through a Pixel or the Conversions API by 1 June.
This is the same playbook every ad platform runs. First they sell reach. Then they sell outcomes. ChatGPT got here fast. The ads pilot crossed US$100 million in annualised revenue within six weeks of launch, and the self-serve Ads Manager is now open to US businesses with no minimum spend.
OpenAI is also promising CPA bidding and third-party measurement, the two things that move a channel from interesting to buyable for serious advertisers.
Why it matters
ChatGPT handles billions of prompts a day. People are asking it the questions they used to type into Google, including the ones with buying intent. An ad surface there is not a novelty, it is a new front door. For Australian advertisers it is not buyable on the same terms yet, but the direction is set and the businesses with clean conversion tracking will be first in line when it opens here.

The quiet lesson is in the entry rule. The platforms now gate access on whether you can pass back conversion data. If your tracking is a mess, you do not just measure worse, you get locked out of the good tools.
What to do about it
The search box is splitting into many boxes. The businesses that can measure each one will decide where the spend goes. The rest will guess.
