Walmart reports Q2 earnings on Wednesday, August 19, and the crowd will rightly fixate on the retail giant's headline numbers — same-store sales, margins, inventory dynamics. But the more durable signal embedded in that print sits one step removed from Walmart itself: the accelerating monetization of its first-party shopper data through a fast-growing advertising division that is quietly reshaping the programmatic supply chain.
Walmart Connect launched its Connect Select CTV marketplace with Magnite, PubMatic, FreeWheel, and Index Exchange as preferred SSP partners , embedding those platforms directly into a closed-loop system powered by Walmart's shopper data. PubMatic's Q1 2026 press release confirmed its integration with Walmart Connect Select as a preferred supply partner, delivering curated, high-performing CTV inventory through direct paths. The structural implication is significant: as Walmart's ad revenue line scales, the volume and quality of inventory flowing through its preferred SSPs scales with it — and (PUBM) sits inside that direct supply path, not as a passive open-market participant but as a named partner with post-auction optimization rights.
PubMatic's Connect data platform now counts more than 300 data and commerce media partners, including Walmart Connect and PayPal Ads , and on its Q1 2026 earnings call, PubMatic disclosed that agentic activity drove 80% year-over-year emerging-revenue growth. Each incremental dollar Walmart Connect captures from brand advertisers migrating budgets toward retail CTV is a dollar that routes through preferred SSPs — the Walmart earnings print is as much a read-through on that infrastructure layer as it is a verdict on consumer spending.
