AI may be getting better at telling people what to buy. But shoppers still want someone human to tell them whether the recommendation is actually worth trusting.
That is the behavior Reddit is now trying to turn into an advertising advantage.
At Cannes Lions 2026, Reddit introduced a new set of tools powered by Reddit Community Intelligence, its engine built on what the company says are more than 25 billion posts and comments across the platform. The pitch is simple: if people are already using Reddit to validate buying decisions, brands should be able to build ads, shopping placements, and creative based on those conversations.
The numbers Reddit shared make the case more sharply. Nearly half of shoppers verify AI-generated recommendations on Reddit before buying. Reddit also says redditors trust the platform more than family or friends when checking those AI recommendations. And one in four redditors immediately buy a product after seeing their decision validated on Reddit.
That is a strong claim, but it points to something very real: AI can produce answers at speed, but confidence still often comes from people who have actually used the thing.
Reddit wants the community to become the influencer
Reddit’s announcement is not framed around creators, celebrity endorsements, or polished social proof. It is framed around “real-world experiences,” which Jen Wong, Reddit’s Chief Operating Officer, described as now more important to purchase decisions than reviews from professional critics or influencers.
That line matters because Reddit is not trying to compete with TikTok or Instagram on performance, personality, or entertainment alone. It is packaging the messy credibility of comment threads, product debates, complaints, comparisons, and niche community knowledge as something advertisers can use more directly.
The scale is part of the argument. Reddit says those conversations happen across a community of 127 million daily active uniques. For brands, that means Reddit is not only a place where people discuss products after purchase. It is increasingly a place where the buying decision is checked, challenged, accelerated, or abandoned.
In other words, Reddit is trying to sell the moment before the purchase, not just the attention around it.
New ad tools built from conversation
The product updates announced at Cannes show how Reddit wants to operationalize that behavior.
A new Free-form ad generator, now in beta, is designed to help brands create Reddit-style Free-form ads, a format inspired by long-form user posts. Reddit is also launching Tailored Creative Assets in beta, which uses community signals to help advertisers adapt creative to specific audiences and contexts.
Redditor Highlights, now generally available, brings positive redditor comments into ad creative, turning community reactions into visible proof points. Meanwhile, Shopping Listing Ads are entering alpha, giving brands another way to connect product discovery with purchase behavior on the platform.
Reddit also says it is improving machine learning and video optimization to drive stronger ad performance. Taken together, these are not random Cannes announcements. They are a system designed to make ads look, feel, and perform closer to the conversations people already use to make decisions.
That is also where the tension sits. Reddit’s value comes from the perception that its communities are independent, honest, and hard to fake. The more brands pull those signals into advertising, the more carefully Reddit will need to preserve the line between useful community validation and ads that feel like they are borrowing trust too aggressively.
What this changes for brands
For marketers, the lesson is not simply “advertise on Reddit.” It is that purchase influence is moving into places where people ask more specific, more skeptical questions.
A shopper asking “best running shoes” through an AI assistant may receive a clean answer. But the same shopper might still go to Reddit to ask whether the shoes last, whether sizing is weird, whether the brand’s customer service is terrible, or whether the recommendation only looks good because everyone is repeating the same review language.
That changes the type of creative that can work. A polished claim may be useful at the top of the funnel, but Reddit’s new tools are built around the idea that evidence from users can move people faster. One in four redditors buying immediately after validation is the kind of behavior brands usually try to create with reviews, retargeting, or influencer content. Reddit is arguing that its communities already do part of that work organically.
But brands will need to listen before they lift. The comments that make Reddit valuable are often specific, critical, and full of context. Turning them into ad units without understanding the community around them is the fastest way to make the format feel wrong.
The new trust check
Reddit’s move is especially important because it sits directly next to AI search and AI recommendations. As more buying decisions begin with generated answers, the question becomes: where do people go when they do not fully trust the answer?
Reddit wants that place to be Reddit.
That makes Community Intelligence more than an insights product. It is Reddit’s attempt to turn human validation into a measurable advertising product, from creative generation to shopping listings to comment-powered proof.
The strategic consequence is clear: brands can no longer think only about what they say in an ad; they have to care what real people are already saying when shoppers come looking for a reason to believe it.
