What is ChatGPT Ads, and why should your B2B SMB care right now
ChatGPT Ads is OpenAI’s advertising platform that shows sponsored results inside ChatGPT conversations, when a user’s intent matches a product or service. On May 5, 2026, OpenAI opened a self-serve Ads Manager for advertisers in the United States, removing the previous US$250,000 minimum spend. Two days later, on May 7, it announced a pilot expansion into five new markets: the UK, Japan, South Korea, Mexico, and Brazil.
For a B2B small or mid-sized business in Chile or Brazil, this means a brand-new advertising channel — inside the world’s most-used AI tool — is either about to launch or already in pilot. Whoever arrives prepared, with tracking, creative, and budget ready, will have a real edge over competitors who only react once the market officially opens.
Timeline: how ChatGPT Ads reached Brazil (and what’s left for Chile)
- May 2026: OpenAI launches self-serve Ads Manager in the US and announces the pilot expansion to the UK, Japan, South Korea, Mexico, and Brazil.
- OpenAI’s target: US$2.5 billion in ad revenue during 2026, aiming for US$100 billion by 2030.
- Brazil today: the pilot is moving forward, but full self-serve access has no confirmed date yet; advertisers can register interest through OpenAI’s portal.
- Chile: not in the first announced expansion wave — which is a preparation window, not a reason to ignore the topic.
The pattern repeats with every new platform: whoever sets up their account, data feed, and creative before the official opening captures the lowest possible cost per click, since auction competition is lower in the first months. It happened with Google Ads in the 2000s, with Meta Ads afterward, and more recently with TikTok Ads.
How much does advertising on ChatGPT cost: reference CPM and CPC
Based on available data from the US market, where self-serve already runs, reference figures are:
- CPM: around US$60 per thousand impressions, roughly three times Meta Ads and six to ten times Google’s display network.
- General CPC: between US$2 and US$8 per click.
- B2B category CPC: between US$8 and US$15, due to stronger competition for qualified audiences.
- OpenAI’s recommended starting bid: US$3 to US$5 per click for new advertisers.
These are higher figures than Google Ads or Meta Ads in most categories, which makes sense: a user interacting with ChatGPT is mid-conversation with explicit intent, not passively scrolling a feed. For a B2B business selling a high-ticket offer — software, professional services, consulting — that context can justify the cost if targeting is precise.
Requirements to advertise: what your company needs
- A registered legal entity in a country where access is already active (fully in the US; Brazil and Mexico in pilot phase).
- Complete legal company details for the advertiser verification process.
- A valid payment method and a defined target market for the campaign.
- Technical readiness: an installed conversion pixel, a clean product feed or catalog, and landing pages optimized for traffic coming from ChatGPT.
What to prepare today if your SMB is in Chile
Chile isn’t on the expansion list yet, which gives time to get ahead by acting now:
- Clean up your tracking: set up Google Tag Manager properly and confirm your B2B conversions (qualified leads, booked demos, quote requests) are logged without duplicates.
- Define your value proposition in one sentence: ChatGPT ads appear inside a conversational answer, so the message must be direct and answer real search intent.
- Prepare simple creative: without Meta’s visual sophistication, focused on clear copy and a concrete offer.
- Register your company’s interest on OpenAI’s advertiser portal, to get notified as soon as Chile enters the next expansion wave.
Is it worth it for a B2B SMB to advertise on ChatGPT?
It depends on average deal size and sales cycle. If your company sells professional services, B2B software, or consulting with a high contract value, a US$8-15 CPC can be profitable if your close rate is solid. If you sell low-ticket or high-volume products, Google Ads or Meta Ads are probably still more efficient for now, at least until the auction matures and costs come down.
The recommendation from more than 20 years working with B2B SMBs on digital marketing is simple: there’s no need to rush into spending on day one, but you do need to arrive prepared. The competitive edge on new channels is captured in the first few months, while ad demand is still low and targeting algorithms are just learning.
Quick checklist before ChatGPT Ads reaches Chile
- B2B conversion tracking working without errors.
- Value proposition condensed into one clear sentence.
- Fast, mobile-optimized landing page.
- Interest registered on OpenAI’s advertiser portal.
- Test budget defined (no more than 10% of total media budget at first).
ChatGPT Ads is still a channel in formation, but the historical pattern is clear: SMBs that prepare before the official opening are the ones that later report the best returns. It’s worth spending this week getting your house in order.
