The Interactive Advertising Bureau published new research this month showing a real gap between how many ads are actually AI generated and how many consumers think they are seeing. More companies are using AI to build ad creative in 2026 than ever before, and more consumers say they can spot it. The surprising part is what happens once they do. A large share of respondents said knowing an ad was made with AI would make them more likely to buy, not less.
What the Study Found
IAB's research tracked two numbers side by side: how much AI-generated advertising is actually running, and how much consumers believe they are seeing. Both numbers went up in 2026, but not evenly. Younger respondents, especially Gen Z, reported spotting AI-made ads far more often than older age groups, and were also more confident in their guesses.
The finding that should change how marketers think about disclosure: a meaningful share of consumers said explicitly knowing an ad was AI generated would increase their likelihood to purchase, not decrease it. That runs against the assumption most brands have been operating on, that AI disclosure is a trust risk to manage carefully or avoid outright. IAB's data suggests the opposite in a lot of cases. Transparency about the tool used to make an ad reads to many consumers as honesty about the process, not a red flag about the product.
The perception gap itself matters too. If Gen Z consumers already assume most ads they see are AI made, whether or not that is technically true, brands that stay silent about it are not avoiding a conversation. They are just not controlling how it gets answered in the consumer's head.
What This Means for Marketers
Stop treating AI disclosure as damage control. If a meaningful share of your audience already assumes AI involvement and reacts positively when it is confirmed, hiding it is leaving a trust signal on the table, not protecting one. Test a small disclosure line on a creative that was genuinely AI built and watch what happens to click through and purchase intent before assuming it will hurt performance.
This also raises the bar on what AI generated actually needs to look like. If consumers expect it and are fine with it, the competitive advantage shifts to producing AI creative that is genuinely good, not creative that tries to pass as fully human made. This is exactly the gap platforms like KenjiAI (kenjiai.com) are built to close, producing ad creative and campaigns fast enough to test real variations against each other instead of shipping one AI generated ad and hoping it lands.
Segment your messaging by age group if you have the data to do it. A disclosure or an obviously AI stylized creative may land very differently with a 24 year old than a 54 year old, and IAB's numbers suggest that gap is real and measurable right now, not theoretical.
What to Watch Next
Watch your own ad account's engagement data on any creative you already know was AI built, whether it disclosed that or not. If IAB's finding holds on your specific audience, you may already have evidence sitting in your ad account of whether disclosure helps or hurts your particular customer base.
Expect more platforms to add a lightweight AI disclosure label option over the next few months, following the same path photo editing and filters went through years ago. Brands that get ahead of that shift and test it early will have real data before it becomes a requirement instead of a choice. The ones waiting for a mandate will be testing this for the first time under pressure instead of on their own schedule.
