At its first-ever Cannes Lions, OpenAI declared itself an advertising company, projecting $2.5 billion in ad revenue for 2026 and pitching a $100 billion future that would put it alongside the largest players in digital marketing.
For decades, Cannes Lions has been where the advertising industry's biggest players come to court brand budgets, and for decades, that meant Google and Meta owned the room. This week, OpenAI walked in for the first time and made clear it intends to change that. Chief Revenue Officer Denise Dresser stood before CMOs and agency leaders on June 22 and said what the company had been signaling for months: OpenAI is "clearly in the advertising business now."
The framing she used is worth paying attention to. Dresser isn't pitching ChatGPT as another ad inventory slot. She's pitching a shift from what she called the "attention economy" to the "intelligence economy," where the value proposition for advertisers isn't interruption but usefulness. The idea is that a user actively asking ChatGPT which laptop to buy or which airline to book is a fundamentally different kind of lead than someone who glances at a banner while scrolling through a news feed.
OpenAI's internal data supports the targeting pitch. Roughly one-fifth of ChatGPT queries carry commercial intent, concentrated in travel, retail, and financial services. Those aren't people idly browsing. They're in the middle of a decision. As AdExchanger reported from Cannes, OpenAI launched its ad product in February 2026 and has already crossed $100 million in annualized revenue within the first six weeks, with more than 600 advertisers signed on. The company projects that figure reaching $2.5 billion by December, then climbing to $11 billion in 2027, $25 billion in 2028, and $100 billion by 2030.
That $100 billion target is roughly half of Meta's current annual ad revenue. Don't mistake the comparison for a near-term threat. Google's search advertising still runs at a scale that makes ChatGPT's commercial query volume look small, currently sitting at somewhere between 1 and 3 percent of Google's traffic at best, according to analyst estimates. The more immediate pressure isn't a direct revenue grab. It's the competition for incremental budget.
Every major advertiser in 2026 is being asked by their agencies to run test campaigns somewhere new. OpenAI is positioning ChatGPT as the obvious answer to that question, and the Cannes pitch was aimed squarely at the people who write the media plans. If brand dollars start flowing to ChatGPT as experimental spend, even a small reallocation away from Google and Meta is meaningful at the scale those companies operate. CPMs on ChatGPT's ad platform have reportedly settled in the $15 to $35 range, down from early pilots at $60, as click-through rates of around 0.9 to 1.3 percent struggle against Google's 29 percent. OpenAI has real monetization work ahead of it.
There's also a lawsuit hanging in the background. OpenAI was recently sued under California's Invasion of Privacy Act over allegations that it embedded Meta Pixel and Google Analytics into ChatGPT.com, effectively leaking user queries to the same platforms it's trying to displace. OpenAI has not commented publicly on the substance of those claims. For a company pitching advertisers on the premise that conversational AI offers richer, more trusted context than surveillance-based targeting, that's an uncomfortable piece of news to have circulating in Cannes cabanas.
The IPO angle nobody is downplaying
The timing of this advertising push is not coincidental. As FinancialContent reported in April, OpenAI filed confidentially with the SEC on June 8, 2026, targeting an IPO valuation exceeding $1 trillion with Goldman Sachs and Morgan Stanley leading the process. Sam Altman has reportedly told advisers that any valuation below $1 trillion is a "nonstarter," though reports suggest OpenAI is weighing a delay to 2027 to let market conditions settle after SpaceX's rough public debut.
An advertising business changes the story OpenAI tells investors. Until February, the company's revenue model rested on two legs: subscriptions (ChatGPT Plus, Pro, and Team tiers) and API access for developers. Both have been growing fast, but both are also priced in a competitive market where models are getting cheaper every quarter. Advertising, if it scales, adds a third leg with very different economics: one that grows with user engagement rather than compute costs, and one that Wall Street knows how to value because it already values Google and Meta.
Frankly, the $100 billion projection by 2030 requires assuming ChatGPT reaches roughly 2.75 billion weekly users globally. That's a moonshot number. But OpenAI doesn't need to hit the moonshot for the Cannes pitch to succeed. It needs enough advertisers to take the platform seriously enough to move budget, and enough of those early campaigns to perform well enough to stick. The attendance at Cannes, the public declaration from Dresser, the structured rollout from $200,000 minimum spend pilots to a self-serve platform that opened this spring to smaller advertisers: that's a company running a real go-to-market, not a feature test.
The intelligence economy framing will either age as visionary or as marketing copy that didn't survive contact with click-through rates. For now, the brands and agencies sitting in those Cannes sessions have a new number to put into their 2027 media plans, and OpenAI has a new story to tell the underwriters.
