The Rise of Commerce Media Networks: How Retailers Became the New Ad Platforms


Aug 21, 2025

5 Min Read

Ecommerce used to be simple: brands sold, retailers stocked, and ad platforms delivered eyeballs. Then the walls began to move. Privacy killed cheap data, tracking broke, and agencies started guessing harder than ever. Out of that chaos rose something new—the commerce media network, where retail itself became the ad platform.

Commerce media networks (CMNs) are Amazon’s secret empire, Walmart’s next frontier, and Instacart’s golden goose. They are not just marketplaces; they are machines that sell attention wrapped in convenience.

The Power of First-Party Data

Amazon doesn’t guess who you are. It knows. It knows your purchase history, your reorder cadence, the brand of coffee you buy, and even how many times you’ve searched for socks at midnight.

That’s the superpower of CMNs: first-party, consented data gathered at transaction-level accuracy. Unlike Meta or Google, which infer interest, retailers possess the holy grail—authenticated identity.

This precision fuels a new form of targeting: ads that exist within the context of buying. Not adjacent, not predictive—embedded.

The Feedback Loop of Intent

The ad ecosystem used to look like this: impression → click → visit → purchase → report. CMNs collapse that loop into a single act. Every ad click is a transaction; every transaction feeds the next campaign.

Data scientists call this purchase adjacency—the quantifiable advantage of advertising at the point of decision.

Retailers as Media Empires

Amazon Ads generated over $45 billion in revenue last year—more than YouTube. Walmart Connect is already a top-five ad network. Instacart monetizes grocery habits like Netflix monetizes nostalgia.

Every retailer wants in, and they’re racing to own their buyer data. Expect Shopify, DoorDash, and even Uber Eats to become the next wave of ad-selling giants.

What Agencies Got Wrong

Agencies spent a decade building playbooks around CPMs, CPCs, and impressions. Commerce media doesn’t play by those metrics. Success here isn’t about reach—it’s about momentum. The buyer’s momentum, not the brand’s.

When every SKU becomes its own campaign, manual management is suicide. CMNs require machine-driven precision. Enter AI-driven engines like TargetLock.ID, which use recursive data learning to track behavioral clusters, optimize bids in real time, and evolve campaigns automatically.

A New Currency: Certainty

Every marketer wants certainty. CMNs don’t sell impressions—they sell predictability. Every ad dollar is measurable, traceable, accountable. When your ad sits next to the “Add to Cart” button, you’re not hoping—it’s math.

Creative Still Rules

Even in this data-driven landscape, creative remains the oxygen. The best CMN ads don’t scream “BUY.” They whisper relevance. They blend seamlessly into the shopping experience.

Brands that pair storytelling with context—like Nike’s embedded product stories on Zalando or Sephora’s video tutorials within checkout—are redefining what it means to advertise without interrupting.

The Consumer’s Dilemma

If every ad looks native, what does authenticity even mean? We’ve entered an era where advertising no longer feels external. Consumers scroll through marketplaces thinking they’re browsing, but they’re actually navigating algorithmic persuasion.

It’s a paradox of trust—when the most effective ads are the ones you never notice.

Beyond Amazon: The Next Frontier

The next wave of commerce media isn’t limited to mega-retailers. Shopify’s Audiences 2.0, Klarna’s in-app ads, and Stripe’s merchant insights are democratizing precision targeting. Small brands will soon wield the same data intelligence as Amazon—without needing Amazon.

The Anti-Agency Takeaway

The anti-agency philosophy is simple: control your data, control your destiny. Agencies still treat retail ads like just another channel. The truth is, commerce media is the new ecosystem.

The brands who embrace that will no longer rent audiences—they’ll own markets.

The Future of Precision Commerce

By 2027, the top-performing ecommerce companies won’t just advertise—they’ll operate self-learning media ecosystems powered by AI. CMNs will merge with predictive engines, making every impression a calculated move in an automated chess game of growth.

Final Thought: The Ad That Buys Itself

The ultimate form of advertising is one that ceases to feel like one. Commerce media networks have brought us closer to that future—where the line between marketing and selling disappears entirely.

Retailers are no longer middlemen. They’re the architects of attention. And in this new world, precision isn’t optional—it’s survival.
