    M&A Deals: Stagwell-Freestar and DoorDash-Instacart Analyzed

    AdExchanger's podcast 'The Big Story' analyzes two recent acquisitions: Stagwell's purchase of publisher monetization network Freestar, and DoorDash's acquisition of Instacart. The episode questions the strategic logic behind these deals. For Stagwell, Freestar's connections to 1,000 publisher sites could support its principal media business, potentially echoing GroupM's 2007 acquisition of 24/7 Real Media. For DoorDash and Instacart, the merger would combine their retail media offerings (DoorDash Ads and Carrot Ads), potentially consolidating a fragmented retail media market. Carrot Ads also offers white-label retail media services to other retailers, adding another layer to the consolidation. The podcast discusses implications for marketers working with retail media networks.

    • Stagwell acquired publisher monetization network Freestar.
    • DoorDash announced intent to acquire Instacart at a $17 billion valuation.

    Stagwell acquires Freestar to bolster publisher ad sales

    Stagwell, a US-based agency group, has completed the acquisition of Freestar, a publisher monetization platform, marking a strategic move closer to the sell-side of the advertising ecosystem. The deal, announced on October 26, 2026, gives Stagwell access to Freestar's technology, services, and customer relationships, including a network of over 1,000 publishers such as Fortune, Boston Globe Media, The Associated Press, and Essence. Freestar processes nearly one billion ad requests daily. Stagwell aims to leverage this to enhance its audience intelligence, shorten supply paths, and support its AI Media Machine for agentic media buying. Freestar will continue to operate independently under its existing leadership and brand, with Stagwell promising not to interfere in its relationships with DSPs, SSPs, or other ad tech providers. The purchase price was not disclosed. This acquisition supports Stagwell's supply-side buildout and 'Future of News' initiative, though industry observers raise transparency concerns.
