Even as the AI bubble becomes a mainstream talking point on Wall Street, tech companies continue to peddle the fantasy that AI is poised to become an almost magical money-maker. Case in point, OpenAI wants you to believe that by 2030, it’ll be raking in $100 billion a year just from ads alone — even though it’s currently struggling to reach just $1 billion.

That massive gulf was observed in a new analysis from marketing consulting firm Emarketer, first flagged by AdWeek, which found OpenAI is on pace to undershoot its own five-year ad revenue projections by a whopping 90 percent. In fact, Emarketer’s take is even more devastating than that: it estimates that the entire addressable market for chatbot advertising — the maximum amount of money up for grabs overall — at $5.4 billion.

That figure isn’t just bad news for OpenAI, but for every giant tech company, all of which are jockeying for a piece of the AI ad pie. In 2026, Emarketer projects that the combination of OpenAI, Microsoft, Google, and Amazon will bring in under $1 billion in ad revenue. For context, OpenAI had projected that its AI ad revenue alone would hit $2.5 billion by the end of this year.

It all adds up to a difficult question for investors. If the top AI companies — which have burned over $1.6 trillion building AI so far — can’t even hit OpenAI’s meager projection for 2026, what hope do they have of hitting their projections four years from now?

To hit that number, AdWeek observes, OpenAI needs three miracles to happen all at once. First, advertisers have to abandon decades worth of infrastructure built around search engines and social media and put all their advertising budgets into chatbots. Once that happens, OpenAI has to out-muscle previous ad-sales giants like Google and Meta, while the entire AI-ad market balloons from just a six-figure stream in 2026 to a raging, 12-figure river by 2030.

Basically, OpenAI will have to make a lot of history to justify these numbers. And whether it can do so is no small matter: according to OpenAI’s own forecasts, advertising is supposed to make up 36 percent of the company’s total revenue by 2030. If the AI lab can’t make the math work, the company’s five-year financial story falls apart, and with it, a major bullet point justifying one of the largest financial bubbles the world has ever seen.
