ChatGPT Ads is barely five months old and it's already moving fast enough that a June 2026 recap looks meaningfully different from a February one. CPA bidding, a new European market, and the legal groundwork for AI-generated creative all landed within a three-week window. If you're weighing whether to test the channel, this is the update that matters.

ChatGPT Ads Is Growing Up Fast

OpenAI's advertising business crossed $100 million in annualised revenue within six weeks of opening self-serve access on May 5, 2026, with more than 600 advertisers onboard by mid-June. At its Cannes Lions debut, OpenAI projected $2.5 billion in ad revenue by the end of 2026 and $100 billion by 2030 — ambitious numbers, but the platform mechanics backing them up have genuinely matured since the original February launch.

For context on how the format itself works, our guide to what ChatGPT advertising is covers the fundamentals — this article focuses specifically on what's new.

CPA Bidding Arrives

OpenAI activated CPA (cost-per-action) bidding on June 5, 2026, turning ChatGPT Ads into a genuine performance channel rather than an awareness-only placement. Previously, advertisers could only bid on CPM (impressions) or CPC (clicks); CPA bidding lets you optimise directly toward signups, purchases or other conversion events, which is the bidding model most Australian performance marketers are already used to from Google and Meta.

📢 Why this matters: CPA bidding is the clearest signal yet that OpenAI is building ChatGPT Ads as a full-funnel platform, not just a brand-awareness experiment. If you've been waiting for the channel to mature before testing it, this update is a reasonable trigger point.

New Markets: UK, Japan, South Korea, Brazil, Mexico

ChatGPT Ads launched in the UK on June 6, 2026 — OpenAI's first European market — with Zalando among the first advertisers live in-market. Campaign targeting also expanded to Japan and South Korea, with Brazil and Mexico following shortly after. This matters for Australian businesses with international customers or export ambitions, since it signals the platform's geographic reach is scaling in step with its ad tooling, rather than staying US-only while advertiser demand grows elsewhere.

The New Ad Tools Terms: Audience Tools and Creative Tools

On or around June 17, 2026, OpenAI published new Ad Tools Terms defining two significant advertiser features. Audience Tools would let advertisers upload first-party customer data — identifiers, suppression lists and segments — to build custom audiences, similar to Meta's Custom Audiences or Google's Customer Match. Creative Tools would offer AI-powered generation, modification, localisation and translation of ad creative from a brand's existing materials, such as catalogues, website content, images and logos.

As of late June 2026, neither feature was confirmed live inside the Ads Manager — they're policy-announced and pending, not yet available to use. But the legal scaffolding matters: it signals OpenAI is building the permanent infrastructure of an advertising business, not running a temporary pilot.

⚠️ Read before you use it: the Ad Tools Terms reportedly include a data-reuse clause allowing uploaded audience data to help improve OpenAI's broader products, and liability for AI-generated creative sits with the advertiser. Review the terms carefully once these tools go live rather than opting in by default.

What the Data Says So Far

Reported click-through rates on ChatGPT Ads sit around 0.91% — broadly comparable to other social and search placements, though this looks like a structural feature of the format rather than something likely to improve dramatically with optimisation. OpenAI reports that cross-out rates (users dismissing an ad) have dropped by roughly 50% since launch as targeting relevance has improved, and fewer than 20% of eligible users see an ad on any given day, which keeps the experience relatively unobtrusive.

Should Australian Businesses Test ChatGPT Ads Now?

With CPA bidding now live, the minimum viable reason to keep waiting has mostly disappeared. The channel supports performance-oriented goals, targets Australia natively, requires no minimum spend, and carries meaningfully less competition than Google or Meta. The honest caveat is scale: ads only reach logged-in adult users on ChatGPT's Free and Go tiers, which structurally excludes anyone on a paid subscription — so treat this as a testing and diversification channel in 2026, not a wholesale replacement for your existing paid media mix.

The Bottom Line

ChatGPT Ads went from a cautious pilot to a genuine performance channel in the space of a few months, and June 2026 was arguably its most consequential update cycle yet. CPA bidding, international expansion and the legal groundwork for AI creative tools all point the same direction: this is a platform being built for scale, not a temporary experiment. Early movers who test now will have real data before the channel gets crowded.
