ChatGPT Ads are advertisements that appear within a user’s conversation with ChatGPT, clearly labeled and always kept separate from the AI’s own answers. As of September 2026, OpenAI has opened self-serve Ads Manager to dozens of markets including the US, Canada, UK, Australia, New Zealand, Japan, South Korea, India, most of Europe, and parts of the Middle East. Vietnam is not yet on the availability list, though OpenAI already runs a localized Vietnamese-language ads page at ads.openai.com/vi-VN for businesses to register interest.

1. What are ChatGPT Ads and how do they work?

According to OpenAI’s own product description, ads in ChatGPT are designed to appear at the moments people are exploring options, comparing alternatives, or working toward a decision, not inserted randomly into every conversation.

The biggest difference from Google Ads or Meta Ads is targeting logic: ChatGPT ads are matched based on conversational context and landing-page content rather than fixed keywords or personal behavioral profiles. OpenAI has also committed to clear ad labeling, strict separation from ChatGPT’s answers, and no advertiser access to private conversation content or chat history, advertisers only receive aggregated metrics such as impressions and clicks.

2. OpenAI Ads expansion timeline (updated through September 2026)

The pace of ChatGPT’s ad rollout throughout 2026 has been remarkably fast:

• Feb 9, 2026: OpenAI began testing ads with a small group of brands, agency-only access, minimum campaign spend of $250,000.
• March-April 2026: Ad testing expanded to Free and Go tier users in the US; the minimum spend threshold dropped to $50,000.
• May 5, 2026:  Self-serve Ads Manager launched in beta for all US businesses, adding CPC bidding alongside CPM, plus a Conversions API and pixel-based measurement.
• June 2026: Self-serve access expanded to the UK, alongside Canada, Australia and New Zealand; pilot testing also extended to Brazil, Japan, South Korea and Mexico.
• Aug 24, 2026: ChatGPT began showing ads across 31 European countries, including the region’s three largest digital ad markets: Germany, France and the UK.
• Aug 27 – Sep 4, 2026: India rollout began with more than 50 brands via WPP and Omnicom; self-serve Ads Manager officially launched in India on Sep 4, 2026, with daily budgets starting around ₹725 (~$7.60).
• As of Sep 21, 2026, OpenAI’s official availability list covers more than 50 countries across the Americas, Europe, the Middle East and parts of Asia-Pacific, but Vietnam is not yet on that list.

3. Why the growth trajectory matters

Data shared by marketing analyst Neil Patel, and widely cited by regional trade press, suggests ChatGPT’s annualized ad revenue reached roughly $100 million within just six weeks of the self-serve launch, while fewer than 20% of eligible users see an ad on a given day. That gap points to significant remaining headroom as OpenAI keeps expanding both user eligibility and market coverage.

ChatGPT now has more than 800 million weekly active users globally, a scale large enough that brands are starting to treat conversational AI as a genuine new discovery channel alongside search and social.

4. Where does Vietnam stand in this picture?

Although not yet on the Ads Manager availability list, Vietnam is one of the fastest-growing conversational AI markets in the region. Per OpenAI’s own reporting, weekly active users in Vietnam have tripled over the past year, and Vietnam ranks alongside the Philippines among the top five APAC countries for weekly ChatGPT usage.

On the subscription side, ChatGPT Go – OpenAI’s low-cost paid tier – has been available in Vietnam since October 2025 at roughly ₫132,000/month, and has since expanded to more than 170 countries worldwide. The pattern of rolling out an affordable subscription tier before advertising mirrors what happened in India: ChatGPT Go launched there in August 2025, while ads only went live roughly a year later, in August–September 2026.

OpenAI has also already built a Vietnamese-language advertising page at ads.openai.com/vi-VN, where businesses can create an account and get notified the moment self-serve access becomes available in their country, a signal that Vietnam is on the roadmap, even without a confirmed date.

5. What Vietnamese businesses should do now

• Register interest at ads.openai.com/vi-VN to be notified the moment the market opens.
• Start optimizing for AEO/GEO (Answer Engine Optimization / Generative Engine Optimization) now, since ChatGPT ad targeting relies on landing-page and content context rather than keywords, content that AI already understands well carries a dual advantage.
• Prepare ad creative and copy suited to a conversational format, which differs meaningfully from traditional banner or search ads.
• Set up measurement infrastructure – pixel tracking and Conversions API integration – early, since these are the same tools OpenAI rolled out from the start in the US.
• Track upcoming regional expansions, especially in Southeast Asia, as leading indicators for Vietnam.

6. Conclusion

ChatGPT Ads are not yet available in Vietnam, but the gap between “not yet” and “soon” is closing quickly as OpenAI keeps expanding into Europe, India and neighboring APAC markets. As one of the region’s fastest-growing conversational AI markets, Vietnamese businesses have a real advantage if they start preparing content, measurement, and AEO/GEO strategy now rather than waiting for launch day.

7. Frequently Asked Questions

Is ChatGPT Ads Manager available in Vietnam yet?

Not yet. As of September 21, 2026, Vietnam is not included in OpenAI’s official self-serve availability list, even though the platform is already live in several other Asian markets including Japan, South Korea and India.

Can Vietnamese businesses register before the market opens?

Yes. OpenAI runs a Vietnamese-language page at ads.openai.com/vi-VN where businesses can create an account and receive a notification as soon as self-serve access becomes available in Vietnam.

Why prepare AEO/GEO before ChatGPT Ads even launches?

Because ChatGPT ad targeting is based on landing-page and ad-copy context rather than fixed keywords. Content already optimized for AI understanding and citation (AEO/GEO) tends to generate stronger context signals for ads once the channel opens.
