Last updated: Monday, October 5, 2026. This is an extended explainer for an event first announced on September 23, 2026 — reopened today because the ChatGPT ads system is back in the news with a new visual ad format OpenAI announced this morning.
While the AI advertising conversation accelerates after today's announcement of a visual ad format inside ChatGPT, it's worth returning to the story that moved the platform into a new quantitative phase: on September 23, 2026, OpenAI announced that ChatGPT Ads had gone live in seven Asian markets at once — Indonesia, Malaysia, the Philippines, Singapore, Thailand, Vietnam, and Taiwan — bringing the total number of available markets to more than 60 countries, less than a year after the ad platform launched.
Why does this story matter again now? Because it completes today's picture: the geographic expansion widens the "where," while the visual format and measurement stack widen the "how." Together, the two announcements describe the channel as it actually exists today — not as it existed at its first launch.
What exactly happened on September 23?
According to the official post on openai.com, ChatGPT ads went live in the seven new markets immediately, following an earlier wave across Asia-Pacific that included Australia, New Zealand, Japan, South Korea, and India. With this expansion, ads became officially available in more than 60 markets worldwide.
Advertisers were given three paths in:
- OpenAI's advertising solutions team directly, for major brands.
- Agencies: dentsu, Havas Media, Omnicom Media, Publicis Groupe, and WPP — effectively most of the global agency networks.
- Self-service through Ads Manager, available to "eligible businesses" — the door that matters to small and mid-sized companies managing their own campaigns.
The number that explains why the platform keeps expanding
In the same post, OpenAI disclosed that ChatGPT Ads reached $1 billion in annualized revenue run rate by the end of August 2026 — in under 200 days from launch — and that tens of thousands of advertisers now run campaigns on it. Those are growth rates virtually unheard of even in the history of the major ad platforms, and they explain the accelerating geographic cadence we've tracked with you: first the wave of new countries in August, then the European expansion into 31 markets, now Asia.
A quote from Dave Dugan, Vice President and Head of Global Ads Solutions at OpenAI, sums up the philosophy: "We're at the beginning of a new chapter for advertising, with AI creating new ways for businesses and people to connect. Our expansion into more markets across Asia brings that opportunity to businesses of every size, from global brands looking for new ways to grow to entrepreneurs and startups running their first campaign."
How ads inside ChatGPT actually work: the official rules
The principles OpenAI restated in the expansion announcement — and which should underpin any marketer's evaluation of the channel:
- Who sees ads: users on the Free plan and the Go plan only. Plus, Pro, and Enterprise plans remain entirely ad-free.
- Separation from content: ads are always labeled and kept separate from ChatGPT's answers, and advertising does not influence the responses given.
- Privacy: conversations stay private and away from advertisers, customer data is never sold, and users retain control over ad personalization.
- The targeting logic: people come to ChatGPT with intent — planning a trip, choosing software, furnishing a home — and the ad appears "in the moments that spark discovery and shape decisions."
OpenAI also promised to continue "expanding into new markets and building new formats, optimization tools, and measurement solutions" in the coming months — a promise that began materializing literally this week with the visual format announcement.
Lessons from the Asian rollout for every advertiser
The Asia expansion isn't just a map filling in with color; the regional trade press produced observations that serve anyone studying the channel:
- Singapore is a high-value market; Indonesia and Vietnam are volume markets. That's how Singapore's Business Times framed the launch — the platform itself is splitting between monetization markets and scale markets, and strategy should differ accordingly.
- Asian brands haven't piled in yet. Tech in Asia noted on October 5 that the big early bettors are not local brands — meaning auction windows in new markets may temporarily be cheaper. That's a classic opening for agile advertisers.
- E-commerce moves first. Shopee — through Peggy Zhu, its Executive Director of Brand and Growth Marketing — described OpenAI as a valued strategic partner as it expands AI-powered tools for buyers and sellers across its markets, and extended a partnership that began with the Brazil ads launch into Southeast Asia. When commerce platforms move in, marketplace advertisers follow.
- Agencies first, then self-service. Every expansion wave repeats the same structure: global agencies from day one, then Ads Manager opens gradually to eligible businesses. Watch your Ads Manager account status even if your country hasn't been announced yet.
What about markets not yet included? The honest reading
As of this report (October 5, 2026), entire regions remain outside the officially announced waves — the Middle East and much of Africa among them. That does not mean access is impossible; it means the practical way to track it is:
- Register at ads.openai.com — per-country availability shows inside Ads Manager itself, and that's the only trustworthy official channel.
- Prepare early: markets with young audiences and fast AI adoption tend to follow the same adoption curve the Asian markets did. Content readiness before the official announcement is a competitive advantage: comparison pages, clean product descriptions, and FAQs built for "discovery inside the conversation."
- Don't circulate unconfirmed news: any post claiming "ads have reached X country" ahead of an official OpenAI announcement is speculation — treat it as noise.
What does this mean for you as a content creator and marketer?
- Measure the channel with the old metrics: cost per acquisition, share of new customers, and incremental lift — the expanded measurement tools announced today make this possible with your existing stack.
- Build "discovery content" now: a ChatGPT user asks "what's the best plan for running a small clothing store?" — whoever owns the content the model trusts has the edge in winning the clicks that follow.
- Small budgets may win temporarily: the lesson from Asia: new auctions are less crowded in their first months.
- Watch the other side: if your audience skews toward free-plan users, their ChatGPT experience now includes ads — and that changes the competition for their attention.
Quick comparison: where ChatGPT Ads stand after the September wave
| Criterion | Initial launch | August wave (Europe) | September wave (Asia) |
|---|---|---|---|
| Markets | Limited first markets | +31 European markets | +7 Asian markets → 60+ countries total |
| Advertiser access | Mainly via OpenAI teams and agencies | Agencies + tech partners | Agencies + self-service in Ads Manager for eligible businesses |
| Annualized revenue | Counting begins | Accelerating growth | $1B per year by end of August (<200 days) |
| Available formats | Text ads inside the conversation | Format expansion | + visual format in testing (October) |
| Ad audience | Unchanged: Free and Go users only — Plus/Pro/Enterprise ad-free | ||
Honest limitations to keep in mind
- 60+ markets doesn't mean yours: the headline number leads the coverage, but the actual check for your country lives inside Ads Manager only.
- Campaign data in new markets is still short: cross-channel performance comparisons need months of real data, not weekly readouts.
- Reliance on global agencies can raise entry costs: if self-service isn't open for your country, current access runs through intermediaries.
- User behavior inside ChatGPT is untested in unlaunched markets: don't transplant conclusions from Asian markets to your own without local testing once available.

The full timeline: how the platform reached 60+ markets
| Wave | Markets | Impact |
|---|---|---|
| Initial launch | Limited first markets | The clock starts; access via OpenAI teams and agencies |
| First Asia-Pacific wave | Australia, New Zealand, Japan, South Korea, India | First expansion beyond the launch markets |
| August wave | A batch of new countries | Widened the map ahead of the European push |
| European expansion | 31 European markets | The biggest numerical jump at the time |
| September 23 wave | Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam, Taiwan | Crossing 60+ markets |
| October 5 update | United States (visual format test) | A new layer of formats and measurement |
The cadence is clear: a new wave every few weeks since mid-year, each one closing a geographic gap and reopening the same question — when does your region's turn come?
What does "$1 billion annualized run rate" actually mean?
The term deserves clarification so it isn't misread: annualized run rate is calculated by extrapolating recent performance over twelve months — it's a yearly projection of current momentum, not a billion dollars actually accumulated over two hundred days. But even with that caveat, the number is exceptional for two reasons. First, reaching it in under 200 days from the launch of a new ad platform is a pace virtually unmatched among emerging platforms. Second, "tens of thousands of advertisers" means the channel is no longer the preserve of experimental campaigns by a few dozen major brands — it's a market with genuine, diverse demand. Together, those two figures are the direct economic explanation for the accelerating geographic expansion: the platform is extending its threads to wherever advertisers buy.
A practical readiness plan for three audiences
- Regional agencies: if you manage brand accounts selling into markets where ads are already live, now is the time to build a test case — a small campaign, a bounded budget, and clean measurement. Early, clean data is worth gold when agencies later crowd into the same market.
- Store owners: list your target markets and check their status inside Ads Manager weekly — two minutes a week reveals the moment your market opens, ahead of your competitors.
- Content creators: write today the comparison articles and FAQs that both advertisers and consumers will need tomorrow; content built before the wave gets picked up after the wave.
All three audiences share one principle: in emerging markets, the advantage of timing isn't bought with advertising alone, but with the preparation that preceded it.
The bigger question: is ChatGPT becoming a rival ad engine to Google?
The honest answer today: not yet, but the direction is unmistakable. What Google owns is explicit search intent and an enormous volume of daily commercial queries; what ChatGPT owns is deeper, longer conversations reaching 1.2 billion people weekly — and early figures, such as WeightWatchers' 15.3% lower acquisition cost reported by measurement partners today, suggest an efficiency worth testing. The real contest won't be settled by headlines but by attribution quality over the coming months, and OpenAI has only just started building that infrastructure with its measurement partners. The wise marketer treats the new channel as a parallel testing sandbox, not an immediate replacement for mature, carefully measured channels.
