OpenAI has made its debut at the Cannes Lions advertising festival, pitching ChatGPT as a new frontier for brand spending and advertisers. The company's ad platform, which launched in February, aims to capture a significant share of the global digital advertising market, currently dominated by Google, Meta, and Amazon.

According to reports from Cannes, OpenAI has already attracted thousands of advertisers across seven test markets, with plans to expand into additional countries. The company's projections indicate that its ad revenue could reach $2.4 billion in 2026, rising to $11 billion by 2027 and $100 billion by 2030.

What Happened

OpenAI started testing in-chat ads on February 9, targeting logged-in US users on the free tier and the $8/month Go tier. The format is straightforward: clearly labeled sponsored content placed at the bottom of ChatGPT responses. Organic answers remain untouched above the fold.

The company claims that roughly 20% of ChatGPT queries show commercial intent, which it believes makes its ad platform a high-intent ad surface on the internet. In May, OpenAI launched a self-serve Ads Manager beta for US advertisers, supporting both CPC and CPM bidding models with no minimum spend requirement.

Background and Context

The advertising push is inseparable from OpenAI's path to a public listing. The company filed confidentially with the SEC on June 8, targeting an autumn debut at a valuation that could exceed $1 trillion. Advertising revenue is the lever OpenAI needs to convince public-market investors that it has multiple revenue streams beyond subscriptions and API access.

ChatGPT's user base, which crossed one billion weekly active users in May 2026, gives it the scale. However, what it lacks is proof that the ad model converts at rates that justify the projections. The company's $100 billion target assumes ChatGPT's products will reach 2.75 billion weekly users by 2030, nearly triple the current figure.

Why It Matters to the Industry

The advertising push is being watched closely because it breaks a tacit consensus among AI companies that chatbot ads are premature. Anthropic used a Super Bowl ad in February to declare that Claude would remain ad-free, framing the decision as a matter of trust: "Users shouldn't have to second-guess whether an AI is genuinely helping them or subtly steering the conversation towards something monetisable."

Google has denied current plans to bring ads to its Gemini chatbot, though SVP Nick Fox has since said the possibility is "not ruled out." The company already runs ads in AI Overviews and is testing them in AI Mode, which means the question is not whether Google will monetise AI-assisted search but how quickly it moves beyond its existing surfaces.

What Comes Next

OpenAI's move into advertising is a significant development for the industry. The company's ad platform has already shown promise, with early data indicating that it can deliver high-intent ads to users. However, the company still needs to prove that its ad model converts at rates that justify its projections.

The success of OpenAI's ad platform will depend on several factors, including its ability to scale and its capacity to maintain user trust. The company has stated that it will not allow money to influence ChatGPT's answers and will keep conversations private from advertisers. However, the company's own pricing trajectory suggests that the market is still working out what a ChatGPT ad is actually worth.
