Commerce Media as the Broader Category

Retail media networks are the best-known subset of a larger category: commerce media — any advertising opportunity built on first-party transaction or purchase-intent data from a platform where commerce actually happens, whether that platform is a traditional retailer, a delivery app, a travel booking site, a ride-share app, or a payment processor. The defining trait isn't the business category (retail vs. travel vs. delivery) — it's that the advertiser is buying placement adjacent to, or targeted using, real transactional signal rather than inferred interest.

Where Commerce Media Is Expanding Beyond Retail

Delivery and food platforms (DoorDash Ads, Uber Advertising, Instacart) monetize order-history and real-time intent signals the same way a retailer monetizes product-page traffic. Travel platforms (Booking.com, Expedia Group Media Solutions) sell placements targeted by actual booking intent and historical travel data. Payment and fintech platforms (PayPal Ads, financial institution-run ad networks) are newer entrants, monetizing purchase-category-level spending signal they're uniquely positioned to observe across many merchants at once — a scope no single retailer's first-party data can match, since it spans purchases made anywhere the payment method is used, not just on one property.

Commerce Media Players Beyond Traditional Retail

Category	Example Players	Unique Data Advantage
Delivery / food	DoorDash Ads, Uber Advertising, Instacart	Real-time, hyper-local order intent
Travel	Expedia Group Media Solutions, Booking.com	Trip intent, booking lead time, destination affinity
Payments / fintech	PayPal Ads, card-network ad programs	Cross-merchant spend visibility, not limited to one property
Ride-share / mobility	Uber Advertising (in-app placements)	Location + trip-pattern signal

The Common Technical Pattern

Across every commerce media vertical, the implementation pattern repeats: a self-serve or managed ad platform sits on top of the company's own transaction database, exposes targeting based on purchase category/frequency/recency rather than generic demographic or interest data, and reports performance using closed-loop attribution against the same transaction database — functionally the identical architecture as a retail media network, just applied to a different first-party dataset. This is why ad tech platform vendors (Criteo, Epsilon, Koddi, Topsort) now sell 'commerce media platform' infrastructure explicitly designed to be white-labeled across any company with a sufficiently large first-party transaction dataset, not just traditional retailers.

Any Company With Transaction Data Is a Potential Commerce Media Player

The barrier to launching a commerce media business has dropped significantly as off-the-shelf platform infrastructure (Koddi, Topsort, Criteo Retail Media) has matured — a company no longer needs Amazon-scale internal ad tech to monetize its transaction data. This is pushing commerce media into categories that would have seemed implausible a few years ago, including B2B marketplaces and even some SaaS platforms with embedded commerce flows.

Advertiser Fatigue Is a Real Risk as the Category Expands

As dozens of commerce media networks launch simultaneously, each demanding separate budget allocation, separate campaign setup, and separate reporting reconciliation, advertisers increasingly push back on fragmentation — some brands have publicly stated they're consolidating spend toward the few commerce media platforms proving measurable incremental ROAS rather than spreading thin across every new network that launches.

What's Next?

Commerce media's growth is closely tied to the rise of shoppable content formats, where the commerce transaction and the media impression increasingly happen in the exact same interaction.
