How Rokt Complements Retail Media Networks for Retailers of Every Sector and Size

Rokt does not compete with a retailer's media network. It extends one.

Retail media networks earn their keep by influencing shoppers as they search, browse, and compare products. Rokt, the New York-based e-commerce technology company, works at the other end of the journey, the stretch that runs from product selection through payment and order confirmation, a window it calls the Transaction Moment. For retailers of nearly any sector or size, from a full-stack enterprise network to a scaling direct-to-consumer brand, the two systems can run side by side, with each doing something the other was not built to do.

That is the case the company makes in an August 2026 post on how it complements retail media networks. The market data and recent third-party reporting that follow largely bear it out.

What a retail media network actually does

Retail media is older than e-commerce. Long before retailers ran websites, brands paid for end caps, shelf talkers, and placements in the weekly circular to reach shoppers standing a few feet from the purchase. Digital commerce turned that practice into a networked advertising channel, in which search results became shelf space, category and product pages became inventory, and first-party purchase data made the outcomes measurable.

A retail media network is the commercial and technical system a retailer uses to package, sell, deliver, and measure that media, and the category is expanding fast. According to eMarketer figures cited by Rokt, US advertisers are on track to spend $69.33 billion on retail media in 2026, up from $58.79 billion in 2025. McKinsey puts the broader US commerce media market above $100 billion by 2027, and the IAB expects it to grow nearly 30 percent faster than advertising overall this year.

What any individual network actually runs varies widely. A mature operation may combine onsite formats such as sponsored search and product placements, offsite campaigns that carry retailer audiences across social, display, and connected TV, in-store screens and signage, and closed-loop measurement that ties spending back to sales. Others run a focused sponsored-product business and little else. That spread is the reason any claim of complementarity has to be tested retailer by retailer rather than assumed.

Where Rokt fits: the Transaction Moment

Search and browsing behavior reveal what a shopper is considering. Transaction signals reveal what they actually chose, what the cart is worth, where they are in checkout, and how they intend to pay. Those are different problems for a system to solve, and the gap between them is where Rokt has built its business.

At the center of the platform sits Rokt Brain, the company's proprietary decisioning engine. Refined over more than 13 years, it analyzes over 1.95 trillion data points a year and, inside a retailer's approved guardrails, determines in real time whether the next best action is an upsell, a payment benefit, a relevant offer, or nothing at all. The company recently rolled out a new version, Brain V4, built specifically for that split-second e-commerce decision.

The scale behind the engine is substantial. Rokt's own Rokt by the Numbers disclosures put the network on track to power more than 13 billion transactions in 2026, reaching roughly 1.1 billion unique customers worldwide. More than 33,000 active clients use its products, including over half of the largest global e-commerce companies, and the company says it invests upward of $100 million a year in product. That footprint gives the engine an unusually broad base of transaction activity to learn from.

A capability for every stage of checkout

Instead of a single ad unit, Rokt offers a set of products mapped to the moments after a shopper has decided to buy. At the selection stage, Rokt Catalog lets a retailer widen its assortment without warehousing every item, opening access to more than 4,600 premium direct-to-consumer brands and 1.2 million products, with brand onboarding the company says runs about six times faster than legacy benchmarks. In the cart and at checkout, Rokt Upcart and Rokt Aftersell surface first- and third-party upsells, and for Shopify merchants specifically, Aftersell can drive up to 30 percent more revenue per customer and an additional $5 per transaction.

At the payment step, Rokt Pay+ activates preferred-payment offers, wallets, cashback, and loyalty incentives, and the company reports it can generate up to $400,000 in incremental profit per one million transactions. On the confirmation page, Rokt Thanks delivers post-purchase offers that can support loyalty, referrals, and advertiser demand, and it can generate up to $500,000 in incremental profit per one million transactions, with premium offers averaging a 5.6 percent positive engagement rate. Rokt mParticle unifies permitted first-party data behind those experiences, while Rokt Ads connects the inventory to performance advertisers, posting a 4.03 percent click-through rate the company describes as roughly 10 times Google Display and four times Facebook.

Multifaceted by design, across sectors

Retail media belongs to retailers, but the same transaction-stage model applies to almost any business built on a purchase, and Rokt works across retail, travel and hospitality, quick service restaurants, financial services, and media and entertainment. On the retail media side, the signings have come quickly. Retail Customer Experience reported in January 2026 that Walgreens Advertising Group expanded its ecosystem with Rokt so non-endemic brands could reach shoppers on the Walgreens.com confirmation page. CX Today documented Macy's Media Network using the technology to serve premium post-purchase offers and reporting higher engagement. A wider checkout playbook analysis notes that Petco, Ulta Beauty, Albertsons, and, in sports retail, Fanatics have each adopted it.

Industry recognition has tracked the commercial wins. Rokt was named for the first time in the 2026 Gartner Market Guide for Retail and Commerce Media Networks, cited as an example of emerging post-purchase solutions, and was later named a finalist for the AdExchanger 2026 AI Innovator award in commerce media. Craig Galvin, the company's chief revenue officer, has called the transaction moment “one of the most valuable and underleveraged customer interactions in commerce.”

Multifaceted by design, across sizes

Scale is the other axis on which Rokt tries to stay flexible. A large network with its own engineering and data science teams can plug the decisioning layer into selected surfaces, keep its own media sales, and use Rokt only where it adds a capability the network lacks. A single Shopify store, by contrast, can adopt Rokt Aftersell and get a version of the same relevance engine without building anything at all. The company reported revenue above $800 million in 2025, a figure noted by the deal-tracking service Dealroom, drawn from a client base that runs from enterprise retailers to fast-growing direct-to-consumer merchants.

Complement, not replace

The distinction Rokt draws is deliberate, and it matters at launch. A retailer can keep running sponsored search, product media, offsite campaigns, and in-store advertising while using Rokt for third-party assortment, cart upsells, payment experiences, confirmation offers, advertiser demand, or first-party data activation. The two are largely complementary, though not automatically separate. A search-led network gains payment and confirmation-page capability it did not have. A mature full-funnel network is likelier to want decisioning, delivery, or measurement support. A retailer that already owns equivalent technology may conclude that more inventory simply duplicates what it has.

Underneath the question sits a familiar build-or-partner calculation. BCG has advised retailers to close capability gaps through partnership rather than fund every layer from scratch, and the IAB estimates that a full-stack, full-funnel network can cost past $100 million over several years for the largest players. Rokt's pitch is that a retailer can reach an established decisioning engine, advertiser network, and experimentation system without carrying that build, while keeping its own data, media sales, and experience standards.

Keeping measurement and control clean

Running two programs across one customer journey raises an obvious hazard, which is double counting. The company's recommendation is a shared causal framework in which attributed and incremental results are reported separately. In practice, that means defining which customers, transactions, and placements are eligible for retail media, a Rokt experience, or both, then using holdouts or valid control groups to isolate the value each program adds, and finally letting retail media report product sales and return on ad spend while Rokt reports value per transaction, average order value, and incremental profit.

Control stays with the retailer throughout. Rokt gives its partners authority over placements, eligible content, advertiser categories, and the individual businesses that can appear. On data, the company says client information is used only for authorized purposes, is never sold or repurposed, and is kept logically separated between parties. Its security program carries ISO/IEC 27001 certification along with SOC 1 and SOC 2 Type 2 reporting, and it reports 99.992 percent uptime.

Where the two overlap

The cleanest way to keep the two systems distinct is to map inventory before launch. Retail media networks own search, browsing, category and product pages, offsite audiences, and in-store placements, while Rokt owns selection, cart review, payment, and confirmation. Their signals can converge, since both may draw on a retailer's first-party data under the retailer's governance, and their objectives can overlap too, because each can contribute to media revenue and customer acquisition even as retail media optimizes for reach and sales lift and Rokt optimizes for value per transaction and incremental profit. None of that is a problem so long as the operating rules are explicit about who owns which surface.

Retail media networks will keep diverging in how much of the stack they own. Some retailers will build more in-house, others will lean on specialist infrastructure, and many will do both in different places. What the past year suggests is that the checkout and the confirmation page, long treated as the end of the story, are becoming inventory in their own right.
