This isn’t really a versus. One of these is a dependable, measurable machine you can scale today. The other is a genuinely exciting surface that is seven weeks old and can’t yet prove it converts. Treat them accordingly.
Meta is the workhorse: 3.58 billion daily users, nearly $200 billion in annual ad revenue, and an AI-driven system that is measurably improving return on ad spend. For demand generation today, almost nothing matches it.
ChatGPT ads are the frontier: a real, fast-growing audience, but no real targeting or measurement yet, and early click-through rates a fraction of Google’s. The right move is a small, watchful test on ChatGPT while Meta carries the load. Here’s the case.
Meta is the biggest paid audience on earth.
Start with scale that’s already monetized. Meta’s apps reach 3.58 billion daily active people, and the business turned that into $196.2 billion in ad revenue in 2025 alone, up 22% year over year.
This is not a platform you’re betting on. It’s a platform that already works, at a scale nothing else in social touches. For most advertisers, it’s the dependable core of a paid program.
A proven, fully monetized machine
Meta’s AI is lifting return on ad spend.
The engine isn’t standing still. Meta reports that advertisers using its AI-driven tools see about 22% higher return on ad spend: roughly $4.52 back for every $1 spent, versus $3.71 without.
That’s the quiet advantage of a mature platform: years of optimization compounding into better results on the same budget. A brand-new ad surface has none of that yet.
What Meta’s AI tools do to ROAS
ChatGPT ads are new, and unproven.
ChatGPT ads launched in testing on February 9, 2026, only on the Free and Go tiers. The commercial pull is real (more than $100 million in annualized revenue within roughly six weeks, 600-plus advertisers) but performance is shaky. One reported client saw a 0.91% click-through rate against a 6.4% Google search benchmark in the same sector, roughly seven times lower.
There’s also almost no targeting or measurement yet, and deals are still done largely by hand. That’s not a knock; it’s just what a seven-week-old ad product looks like. You test it. You don’t bet the budget on it.
A 0.91% click-through rate against a 6.4% Google benchmark. The audience is real; the performance isn’t proven.
ChatGPT ad performance vs a Google benchmark
The frontier isn’t noise. It’s just early.
Don’t dismiss it either. 34% of US adults have used ChatGPT, double the 2023 share, rising to 58% of adults under 30. That’s a genuine, growing, high-intent audience worth establishing a presence with early.
The reason to test now is positioning: being among the first advertisers a new surface learns to serve well. Just size the bet to the proof, which today is thin.
A real, fast-growing audience
Fund the proven. Test the frontier.
Put it in perspective: Meta did $196 billion in ad revenue last year; ChatGPT ads are tracking around $100 million annualized. That’s the size of the bet, today. Keep the bulk of your budget on the platform that measures and converts, and carve out a small, watchful test on the one that doesn’t yet.
When ChatGPT ads add real targeting and measurement, scale into them on evidence. Until then, frontier money stays frontier-sized.

While ChatGPT offers access to a fast-growing, high-intent audience, the lack of measurement and evolving product features make it a challenging channel.
