The global retail media ad market will hit $200B in 2026 and climb past $220B in 2027, representing 15.2% of total worldwide ad investment. Exclude Amazon, though, and retail media's year-over-year growth is predicted to dip to 9.8% in 2027, the lowest growth rate since the World Advertising Research Center (WARC) began tracking the category in 2021, and much lower than the 20%+ sustained growth many predicted as the pandemic wound down.
Retail media was the buzzword of every other marketing conference panel in 2024; now it has largely been demoted to a sidenote in AI discourse. What could be seen as a warning sign, though, is actually a channel settling into normal, stable growth after several years of abnormal ones.
The Gold Rush Is Over
Retail media's early boom was fueled by pandemic-era necessity. Many retailers that had been sleeping on e-commerce infrastructure suddenly had no choice but to build it, fast. Digital retail ads were a suddenly relevant, profitable revenue stream for the retailers that could meet the occasion. Those that had already laid the groundwork made the quickest gains, while many white-labeled their way to solutions and scrambled just to have a seat at the table.
That urgency fast-tracked the infrastructure and produced real growth, but the growth was built on a low bar: having retail media at all. Brands were just testing the waters, looking to answer who had viable options in their space. In 2026, the question is sharper: Does this retailer solve a specific problem for our brand, and can we prove it?
Scale Still Matters, But It's No Longer the Whole Game
Amazon remains the dominant network across the entire landscape, and that's not changing any time soon. But the flattening growth outside of Amazon points to something else happening beneath the surface: the broad-based expansion phase is giving way to a more selective market. Advertisers are looking beyond simply covering their footprint and are increasingly finding lasting value in localized, point-of-purchase messaging that national scale alone can’t replicate.
This is where the real opportunity opens up for regional and smaller networks. A concentrated regional grocer (a Meijer or Hy-Vee, for instance) doesn't need national reach. It needs relevance. These retailers know their local shoppers well enough to serve a message that lands, which beats reaching everyone with a message that doesn't.
While relevance is an essential starting point, smaller networks still need the technology or differentiating capability to actually deliver on that promise. First-party data infrastructure, measurement credibility, or genuinely unique inventory are the ways brands will shift their Amazon budgets (or even their brand budgets) into smaller-scale networks.
Inventory Has to Earn Its Place
That differentiation only works if the underlying inventory can support it. Retail media's brand-building potential is only as good as the inventory that carries it, and how well the retailer has conditioned its shoppers to actually engage with it.
If a retailer monetizes every available surface without strategy, ads stop being messages and start being noise, degrading the shopping experience. That ultimately hurts everyone's sales, the brand's and the retailers alike. The retailers who understand that ad relevance is additive to the experience, not a tax on it, are the ones building durable, trusted inventory. That trust is the actual foundation brand-building depends on.
WARC's own read is that retail media converts demand but underbuilds brand. That's arguably true if brand-building means buying awareness. But if brand-building also means becoming part of a community’s routine, then showing up consistently in the regional retailers people actually identify with becomes a form of brand-building in its own right.
Not All Verticals Are the Same
Retail media remains exceptionally good at one thing: influencing which product a shopper picks in the moment. It's far less effective at making someone care about a need state they weren't already considering. This is why grocery and verticals with short consideration windows and essential needs are primed for conversion media and continue to lead the charge, while electronics and large home purchases are advancing more unevenly, and non-endemic networks (those not selling physical products) are moving slower still.
Purchase-behavior signals like loyalty data, brand-switching tendencies, and basket adjacency consistently outperform simple demographic or category targeting. Consider serving a protein-focused milk message to shoppers actively searching for protein shakes. It's not a random cross-sell; it's a need-state-driven message landing at exactly the right moment, surfacing something the shopper hadn't acted on but is primed to hear. Shoppers can tell the difference.
What’s Next
What we're watching is a channel settling into its permanent role in the total media mix, growing at a sustainable pace instead of the artificial, uncontrolled rate of a bubble market where everyone raced to grab a new revenue stream before anyone understood what actually worked. And that maturity is reshaping who's positioned to win next.
The next growth phase won't be won by whoever offers the most impressions, but by whoever earns the most trust, through relevant inventory, credible measurement, and a genuine understanding of what a shopper needs in the moment. Amazon will keep setting the scale benchmark, but the real story of the next few years will be written by the networks, regional and national alike, that treat relevance as the strategy rather than an afterthought. For brands, that means rethinking where budget goes: not toward whoever offers the biggest reach, but toward whoever can prove they'll actually move the shopper standing in front of them. The $200 billion headline will keep growing. The winners will be the ones who understood, long before the numbers caught up, that in retail media, relevance was always the real currency.
