OpenAI Is Building an Advertising Business. Here's What We Know.

OpenAI is developing an advertising product, according to reporting from multiple outlets in early 2026. The company has hired advertising industry veterans, is in early conversations with major brands and agency holding companies, and is expected to launch a beta advertising product within 2026.

The development marks a significant strategic pivot for a company that has, until now, operated exclusively on subscription and API revenue.

What Is Being Built

OpenAI has not made a formal announcement. The available reporting describes a sponsored content product that would allow brands to pay for placement within ChatGPT responses — similar in structure to Perplexity's sponsored answers product, which launched in 2025.

The mechanics under discussion: when a ChatGPT user submits a query with commercial intent ("recommend a project management tool for a 20-person team," "best airline for frequent domestic travel"), a sponsored unit would appear alongside the AI-generated answer. The unit would be clearly labelled as sponsored. The AI's organic recommendation would remain unaltered.

OpenAI is also reportedly exploring a product that would allow brands to sponsor specific capability integrations — appearing as the recommended provider when a user asks ChatGPT to complete a task that requires a third-party service (booking travel, ordering food, researching a purchase).

Why This Is a Big Number

ChatGPT has approximately 500 million weekly active users as of early 2026. The intent quality of queries submitted to ChatGPT is substantially higher than the intent signals available in standard display advertising — users express specific, decision-proximate needs in natural language, at the moment of decision.

For comparison: Google Search, which monetised through this same intent signal mechanism, generated approximately $175 billion in annual advertising revenue in 2024. ChatGPT's user base and query volume are smaller but growing rapidly. The addressable advertising market within an AI assistant with 500 million weekly users is a material number by any measure.

OpenAI's current revenue is approximately $4 billion annually, primarily from ChatGPT Plus subscriptions and API usage. An advertising product with meaningful scale could double or triple that figure within 24 months if execution goes well.

What This Means for Advertising

The entry of OpenAI into advertising — following Perplexity's earlier move — confirms that the AI answer layer will be commercially monetised through advertising. The question is no longer whether this happens but how quickly and in what format.

For brands, the implication is direct: ChatGPT is already influencing purchase decisions for 500 million weekly users, and those users currently see no advertising. That inventory will become available. The brands that develop the capability to run campaigns in this format before it reaches the open market will have first-mover pricing and learning advantages.

For agencies, the question is whether AI advertising requires a different media buying approach. The intent signal is stronger than display and comparable to search; the targeting mechanism is semantic (query-based) rather than audience-based; the creative format is text-within-answer rather than display unit. The buying workflow is closer to search than to programmatic display, but neither maps perfectly.

For the programmatic industry, the emergence of AI advertising as a distinct channel — with high intent signals, large scale, and premium CPMs — will draw budget from existing channels. The clearest risk is to search advertising, where the query intent is directly comparable and ChatGPT is already capturing queries that would previously have gone to Google.

The Publisher Question

OpenAI's advertising product, like Perplexity's, does not resolve the fundamental tension between AI answer interfaces and publishers. When ChatGPT answers a question using information from a publisher's content, that publisher is not compensated. If OpenAI then monetises the same answer with advertising, the publisher whose content enabled the answer receives nothing from the ad revenue.

This dynamic is the subject of active litigation and licensing negotiations between OpenAI and several major publishers. The advertising product announcement will intensify those conversations — it is harder to argue that AI assistants should use publisher content without compensation when those same assistants are selling advertising against it.

The advertising model for AI is being constructed right now, with the architecture and economics still undecided. The decisions made in the next 12-18 months — who gets paid, how budgets flow, what the targeting model looks like — will shape the industry for a decade.
