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.

Advertisers Seek Clarity on DoorDash-Instacart Deal Implications
DoorDash's planned $17 billion acquisition of Instacart, announced nearly a week ago, has media buyers questioning the impact on retail media costs, data integration, and measurement. While the deal is not expected to close until late 2027 or early 2028 and faces FTC antitrust review, advertisers are already considering the potential scale and data advantages of the combined delivery platforms. Key concerns include the integration of their separate ad businesses, premium pricing, comparison with Walmart and Amazon's retail media dominance, and the ability to deliver independent, credible measurement. Industry analysts view this as a possible catalyst for retail media consolidation, emphasizing the importance of scale and measurement in commerce media.
Liquid Death and Ibotta Execs on Incrementality Over ROAS
In an Adweek podcast episode recorded at Brandweek 2026, Ibotta CEO Bryan Leach and Liquid Death's Chief Media and Digital Commerce Officer Benoit Vatere discuss the limitations of ROAS in measuring promotional effectiveness for CPG brands. They advocate for incrementality as a truer measure, using matched-audience testing to identify genuinely incremental sales and cost per incremental dollar to protect margins. The conversation covers optimizing promotional spend across retail channels, reducing customer churn, growing household penetration, and reallocating budgets based on real-time sales signals. They emphasize the importance of third-party verification to build trust in retail media results.
AI Video Savings Should Fund More Output, Not Fee Cuts
Lindsay Hong, former COO of Stagwell's Locaria and current podcast host, argues that AI-driven reductions in video production costs should prompt brands to demand increased output from agencies rather than lower fees. IAB research shows 86% of buyers use or plan to use generative AI for video creative. ISBA's 2026 survey indicates 76% of UK advertisers prioritize efficiency in their AI strategies, leading procurement teams to pressure agencies for rate cuts. Hong counters with Jevons' Paradox, citing that cheaper production historically leads to more demand, not reduced spending. She advocates for agencies to shift from hourly billing to output- or outcome-based pricing and emphasizes the growing importance of discernment, quality control, and channel strategy. While some simple production may move in-house, agencies that excel in strategy and judgement can preserve or enhance their value.
