Advertising inside AI platforms is moving quickly from experiment to reality.
The advertising pilot within ChatGPT has already reached $100 million in annualised revenue within just six weeks, demonstrating strong early demand from brands looking to reach users in conversational AI environments.
While still at an early stage, it signals a potential shift in how digital advertising could evolve over the coming years.
For businesses investing in digital marketing, it is another development that highlights how quickly online discovery behaviour is changing.
Where ChatGPT Advertising Is Available
At present, the advertising pilot is primarily limited to users in the United States, where ads appear within the free versions of the platform.
Initial expansion is expected to include markets such as Canada, Australia and New Zealand, with further international rollout likely during 2026.
For businesses and advertisers in the UK and Europe, the platform is not yet available as an advertising channel. However, the speed at which the pilot has generated revenue suggests that broader access may not be far away.
Self-Serve Advertising Tools Coming Soon
One of the most significant developments for marketers is the expected launch of self-serve advertising tools.
Currently the pilot programme has largely involved larger brands and agency partners. A self-serve platform would allow businesses to create and manage campaigns directly, similar to platforms such as Google Ads and Meta Ads Manager.
Opening the platform to self-service would make it accessible to smaller businesses and marketing teams, rather than just enterprise advertisers.
A New Type of Digital Discovery
The rise of AI assistants introduces a different model of online discovery.
Traditionally, digital marketing has revolved around search engines such as Google Search.
Traditional search journey –
- User searches using keywords
- Search results appear
- Ads and organic listings compete for clicks
AI platforms change that behaviour.
Conversational discovery –
- A user asks a question
- AI provides a structured answer
- Relevant sponsored suggestions may appear alongside the conversation
This interaction often happens later in the research process, when someone is already exploring options or comparing providers.
For marketers, that could make conversational AI environments particularly valuable.
Early Insights From the Advertising Pilot
While still evolving, the pilot programme offers some useful insights into how advertising may work within AI platforms.
- Ads appear separately from AI responses, clearly labelled as sponsored
- Sponsored placements do not influence the AI’s answers
- Advertisers do not receive access to user conversations
- More than 600 advertisers have already joined the programme
At present, fewer than 20% of eligible users see ads on a daily basis, suggesting the platform is still operating at a relatively early scale.
What UK Businesses Should Be Thinking About
Although ChatGPT advertising is not yet available in the UK, it reflects a broader shift in how people search for and evaluate products and services.
AI tools are increasingly becoming part of the research process, sitting alongside traditional search engines and social media platforms.
For businesses investing in search engine marketing, the key priorities remain clear:
- Maintain a strong SEO strategy to ensure visibility in search results, with an AEO / GEO content strategy to cover AI searches.
- Continue to optimise PPC campaigns on Google, Bing and Social media platforms.
- Monitor how AI platforms influence customer research behaviour.
- Be prepared to test emerging advertising channels as they become available.
The Bigger Shift in Digital Marketing
The rapid growth of ChatGPT’s advertising pilot highlights a wider trend.
AI assistants are becoming another gateway to information, recommendations and product discovery. Over time, this could create a new advertising channel sitting somewhere between search and content discovery.
For businesses focused on digital growth, the key is not to chase every new platform, but to understand how these developments fit into a broader marketing strategy.
AI platforms may not replace search marketing any time soon, but they are clearly becoming part of the ecosystem.
