Twenty measurement and verification partners now cover attribution, incrementality and brand suitability. Australian marketers gain the measurement tools but not the image-ad pilot. KEY TAKEAWAYS 01A visual ChatGPT ad format shown during image generation enters US-only testing later in October 2026. 02Twenty partners now cover conversion, attribution, incrementality and brand suitability for ChatGPT advertisers. 03Australia's ChatGPT ad click-through rate is 0.67%, eighth of nine live markets, per Similarweb panel data. 04OpenAI-supplied figures show WeightWatchers cut cost per acquisition by 15.3% and 67% of Dose's incremental purchases came from new customers. 05DoubleVerify and Integral Ad Science are running brand-suitability pilots; OpenAI says neither can access user conversations. ## The new format When a ChatGPT user requests a generated image, an ad appears during the creation window. OpenAI says the ads are clearly labelled and kept separate from the image being created.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) The format enters US testing later in October 2026, with no date confirmed for other markets. OpenAI has been consistent on one point since text ads launched for US Free and Go users in February 2026: advertising does not influence the answers ChatGPT provides.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) The company repeated that position on 5 October 2026 as the format grows more commercially significant. ## The measurement build-out Weak measurement has been the standing complaint about ChatGPT ads. OpenAI's answer on 5 October 2026 was 20 partners across five categories: conversion data via Hightouch, Tealium and LiveRamp; attribution through AppsFlyer, Triple Whale, Adjust, DV Rockerbox, Northbeam, Branch, Singular, Kochava, Airbridge and Tenjin; full-funnel measurement with Fospha, Measured and INCRMNTAL; incrementality experiments with Haus, Measured and WorkMagic; and brand-suitability pilots with DoubleVerify and Integral Ad Science (IAS).[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) Lidiane Jones, chief executive of IAS, said: "As advertising expands into AI-native environments, marketers need confidence that brand safety protections are durable, consistent, and built to operate at scale." OpenAI says neither verification partner can see users' conversations.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) Brand-suitability tools normally need content context, and chatbot content is personal in a way a webpage is not, so the privacy carve-out matters. OpenAI also published early case figures, supplied by the company and not independently verified. WeightWatchers cut cost per acquisition by 15.3%.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) Sixty-seven per cent of incremental purchases attributed to Dose through WorkMagic came from new customers.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) OpenAI did not disclose the campaign period, spend levels or methodology behind either figure. ## The scale argument ChatGPT now reaches 1.2 billion people each week, which is the number OpenAI leads with.[\[1\]](https://openai.com/index/new-chatgpt-ads-format-and-measurement/?ref=promptthemarket.com) Shamsul Chowdhury, EVP of Paid Social at Zeno Group, put daily query volume in plainer terms: "There are about 2.5 billion prompts globally happening each day on ChatGPT, whereas there's about 15 billion searches on Google."[\[2\]](https://digiday.com/marketing/openai-moves-to-make-chatgpt-ads-more-measurable-and-more-visual/?ref=promptthemarket.com) ChatGPT runs at roughly one-sixth Google's daily query volume, a gap that shapes every conversation about reach and cost efficiency. ## The Australian position OpenAI extended ads to Australia, New Zealand and Canada for Free and Go users on 16 April 2026, giving Australian marketers about six months of live exposure before the 5 October announcement.[\[3\]](https://help.openai.com/en/articles/6825453-chatgpt-release-notes?ref=promptthemarket.com) Paid plans remain ad-free. The measurement expansion applies globally, so Australian buyers can now connect attribution and incrementality tools on the same basis as US buyers. The image-ad pilot is US-only. Similarweb panel data reported by Search Engine Journal on 29 September 2026 put Australia's ChatGPT ad click-through rate (CTR) at 0.67%, eighth of nine live markets.[\[4\]](https://www.searchenginejournal.com/chatgpt-ad-ctr-markets-report/591384/?ref=promptthemarket.com) Brazil, which leads the table, records a CTR nearly three times higher. This publication covered the full ranking when the data was released: [Brazilians click ChatGPT ads almost three times as often as Australians](https://www.promptthemarket.com/brazilians-click-chatgpt-ads-almost-3-times-as-often-as-australians/).[\[5\]](https://www.promptthemarket.com/brazilians-click-chatgpt-ads-almost-3-times-as-often-as-australians/) If Australian users engage less with text ads, a visual format designed to capture attention during image generation could shift that number. Australian marketers will not find out until OpenAI widens the pilot beyond the US, and no timeline has been confirmed. SOURCES & CITATIONS 1.

Ads appear while ChatGPT is generating an image for the user. OpenAI says they are clearly labelled and kept separate from the image output. The format enters US-only testing later in October 2026. Which measurement partners did OpenAI announce? Twenty partners across five categories: Hightouch, Tealium and LiveRamp for conversion data; AppsFlyer, Triple Whale, Adjust, DV Rockerbox, Northbeam, Branch, Singular, Kochava, Airbridge and Tenjin for attribution; Fospha, Measured and INCRMNTAL for full-funnel measurement; Haus, Measured and WorkMagic for incrementality; and DoubleVerify and Integral Ad Science for brand suitability. Can Australian advertisers access the new image-ad format? Not yet. The visual format is US-only in its initial test phase. Australian marketers can access the new measurement partner integrations, which apply globally, but the image-ad pilot has no confirmed date for expansion to Australia. How does ChatGPT's ad reach compare to Google? ChatGPT generates roughly 2.5 billion prompts per day globally, compared to about 15 billion daily searches on Google, making it approximately one-sixth the daily query volume, according to Shamsul Chowdhury, EVP of Paid Social at Zeno Group. ![James Dore](https://storage.ghost.io/c/e4/01/e4017178-c1da-4131-80aa-35f02cb5b999/content/images/2026/09/james-dore.jpg) [James Dore](https://www.promptthemarket.com/james-dore/) James Dore is Strategy Director at Bushnote, a leader in SEO and AEO in Australia.
