Walmart closes Vibe.co deal to scale self-service streaming ad business

Walmart is vertically integrating its ad tech stack to capture long-tail demand from smaller advertisers who previously found CTV cost-prohibitive. By combining Vibe.co's self-service interface with the hardware reach of Vizio (acquired in late 2024), Walmart now controls both the supply and demand layers of its retail media network. This move signals a shift away from third-party DSP reliance toward a closed-loop system where advertiser spend is tied directly to verified in-store and online purchase data. Watch for whether Walmart opens this self-service platform to inventory beyond its own Vizio SmartCast ecosystem to compete more directly with Amazon's DSP.

The finalization of the Vibe.co deal follows a period of rapid expansion for Walmart's advertising division. While financial terms were not officially disclosed in the August 2026 announcement, reports from the Wall Street Journal in June 2026 valued the transaction at approximately $1.4 billion. This acquisition serves as the strategic software counterpart to Walmart’s $2.3 billion purchase of Vizio in late 2024, which provided the retailer with an installed base of over 19 million active accounts and a proprietary operating system, per Walmart's December 2024 filings.

Walmart Connect has become a critical profit driver for the retailer, with global ad revenue reaching roughly $6.4 billion in 2025—a figure that tripled over five years, according to data shared at Cannes Lions in June 2026. This growth has been fueled by a transition from lower-funnel performance ads to upper-funnel video solutions. By March 2026, Walmart reported that its first full quarter integrating Vizio inventory helped drive a 31% year-over-year increase in advertising sales, as noted by Grocery Doppio.

Industry analysts, including those from PYMNTS in August 2026, suggest that Vibe.co transforms Walmart's previous hardware investments into a comprehensive commerce media engine. The platform allows businesses to launch campaigns across 500+ streaming channels with flexible budgets that can start as low as $500, according to Substack reporting from June 2026. This democratization of access is expected to lure mid-market and marketplace sellers who are increasingly seeking transparent attribution in a U.S. CTV market projected by eMarketer to reach $38 billion by the end of 2026.
