Platforms Internalize Checkout Ads

The real risk is that Rokt sits on someone else’s checkout, while the biggest platforms increasingly see checkout media as a product they can own themselves. Rokt’s core deal is simple, it drops an SDK into the purchase flow, shows a sponsored offer after someone buys, and splits advertiser spend with the platform, often 50, 50. That works best before the host platform has built a serious ads business. Once a partner proves ads are high margin, the natural next move is to keep more of that margin in house.

• Uber is the clearest example of partner leverage turning into platform power. Uber used Rokt in checkout, then built a larger ads engine around rides and Uber Eats. Uber said its advertising revenue run rate passed $650M in Q2 2023, $900M in Q4 2023, and $1B in Q2 2024, showing it has both the inventory and internal muscle to monetize transactions directly.

• Wayfair shows the same pattern from a retail angle. Rokt counts Wayfair as a major network partner, but Wayfair has operated Media Solutions for years and now describes retail media as a core profit engine. That means Wayfair already has sales teams, ad tools, and supplier demand in place, which gives it room to push for better economics or route more spend into its own system.

• This is a common outcome in commerce infrastructure. The checkout is where power concentrates because it controls payment flow, shopper data, and the last screen before confirmation. Adjacent research on checkout and marketplaces shows that once platforms own that moment, they tend to layer on ads, seller tools, and monetization products rather than leaving that margin to a partner.

Rokt’s path forward is to become harder to replace than a checkout ad widget. The mParticle acquisition and broader move into first party data, post purchase upsells, and cross channel personalization push it in that direction. If Rokt can own more of the targeting and measurement stack, platforms will have a harder time squeezing it down to a thinner rev share vendor.
