LiveRamp CEO Defends Publicis Deal Amid WPP Exit

LiveRamp at Cannes: From Data Utility to AI Darling

LiveRamp CEO Scott Howe used Cannes Lions 2026 to frame his company's transformation from a behind-the-scenes data infrastructure provider into a central player in the AI advertising revolution. Comparing LiveRamp to the 'geeky, dorky kid who became popular,' Howe unveiled a slate of partnerships—OpenAI for measurement, Adobe for commerce media—that signal a strategic pivot toward AI-driven, transaction-level personalization. But beneath the buzz, a structural tension is emerging: LiveRamp's $2.2 billion acquisition by Publicis Groupe, announced in May, is creating friction with rival holding companies, most notably WPP, which plans to stop using LiveRamp after the deal closes.

The stakes are high. LiveRamp's value proposition has long been its neutrality—a trusted intermediary connecting advertisers, platforms, and publishers. The Publicis deal threatens that perception, and WPP's exit is a concrete signal that the competitive landscape is shifting. For executives evaluating their ad-tech stacks, the question is no longer just about LiveRamp's technology; it's about whether the platform can retain its collaborative ethos under a holding company owner.

The OpenAI-Adobe Axis: A New Data Flywheel

LiveRamp's partnership with OpenAI is a strategic bet that AI chatbots will become major advertising channels. By integrating its Conversions API Hub, LiveRamp enables ChatGPT advertisers to measure campaign effectiveness beyond cookie-based tracking. This is a smart move: OpenAI, which launched ads just four months ago, needs credible measurement to attract brand dollars. Howe's logic is clear: 'If data goes in to make the communication more effective, then shouldn't data also be used to determine whether that was relevant content for the user?'

Simultaneously, the Adobe partnership tackles the creative side of the equation. LiveRamp will supply shopper data to Adobe's GenStudio, allowing commerce media networks to power AI-generated creative with real transaction-level insights. This eliminates reliance on modeled audiences, enabling hyper-personalized creative at scale. For Adobe, it strengthens its commerce media offering; for LiveRamp, it deepens its moat in retail media—a sector growing at 20%+ annually.

Together, these partnerships create a data flywheel: OpenAI provides a new ad channel, Adobe provides a creative engine, and LiveRamp sits in the middle, connecting data, measurement, and activation. The strategic consequence is that LiveRamp is becoming indispensable to the AI advertising ecosystem—but only if it can maintain its neutral position.

The Publicis Paradox: Scale vs. Neutrality

Howe argues that the Publicis acquisition will unlock 'greater resources and flexibility' to scale LiveRamp's business, particularly in international markets where it currently generates only 5% of revenue. Publicis's global footprint could help LiveRamp serve multinational clients like Procter & Gamble and Coca-Cola more effectively. But the flexibility argument is harder to sell. Publicis is buying LiveRamp to accelerate its agentic AI strategy, which means LiveRamp's data will inevitably be used to advantage Publicis's own clients and agencies.

Howe insists that neutrality will remain a mandate: 'Whatever assurance [agencies] need that we’re going to continue to be neutral—of course we are.' But actions speak louder than words. WPP's CEO Cindy Rose announced at Cannes that WPP will stop using LiveRamp after the takeover, citing concerns about competitive advantage. This is a significant blow: WPP is one of the world's largest ad holding companies, and its exit could trigger a domino effect among other agencies that value neutrality.

The strategic calculus for Publicis is clear: acquiring LiveRamp gives it a proprietary data infrastructure that rivals lack. But the cost is LiveRamp's open ecosystem. If other holding companies follow WPP's lead, LiveRamp's addressable market shrinks, and Publicis may end up with a powerful but siloed asset.

Winners and Losers in the New Ad-Tech Order

Winners: Publicis Groupe gains a critical data layer for its agentic AI ambitions, potentially leapfrogging competitors in personalization and measurement. OpenAI secures a credible measurement partner, accelerating its ad platform's adoption. Adobe strengthens its commerce media play, leveraging LiveRamp's shopper data to differentiate GenStudio.

Losers: WPP loses access to LiveRamp's data connectivity, weakening its ad-tech stack and forcing it to seek alternatives. LiveRamp shareholders face uncertainty: the deal's valuation depends on closing, and WPP's exit could pressure the acquisition price or terms. Competing ad-tech firms like The Trade Desk or Criteo may see an opportunity to poach WPP's business.

Neutral but at risk: Independent agencies and brands that rely on LiveRamp's neutrality may need to reassess their partnerships. If LiveRamp becomes perceived as a Publicis tool, its value as a cross-ecosystem connector diminishes.

Market Impact: The Rise of Walled Gardens in Ad-Tech

The LiveRamp-Publicis deal is part of a broader trend: consolidation in ad-tech is creating walled gardens that combine data, creative, and media buying under single ownership. Publicis already owns Epsilon, a major data platform; adding LiveRamp creates a formidable stack. Meanwhile, WPP's exit signals that holding companies are drawing battle lines, each building proprietary infrastructure.

This fragmentation could harm advertisers, who benefit from neutral, interoperable solutions. The OpenAP initiative and other industry efforts to standardize measurement may struggle as platforms become more insular. For now, the market is watching whether Publicis can maintain LiveRamp's open architecture—or whether the acquisition accelerates the shift toward closed ecosystems.

Outlook: What to Watch in the Next 30 Days

Three indicators will determine LiveRamp's trajectory: (1) Whether other major holding companies, like Omnicom or IPG, follow WPP's lead and announce plans to reduce LiveRamp usage. (2) The speed of integration between LiveRamp and Publicis's existing data assets, particularly Epsilon. (3) Adoption rates of the OpenAI and Adobe partnerships, which will signal whether LiveRamp can generate new revenue streams independent of the Publicis deal.

Executives should prepare for a scenario where LiveRamp's neutrality erodes, making it a less attractive partner for multi-homed advertisers. Diversifying data and measurement partners now could mitigate risk. Conversely, if Publicis successfully preserves LiveRamp's open ethos, the combined entity could become the dominant infrastructure layer for AI-driven advertising.
