WPP is in final documentation stages with Coca-Cola to run the beverage giant's international media, data, and technology operations across all markets outside North America, according to three people briefed on the transition. The account carries estimated annual billings north of $2.5 billion, covers 190+ markets, and would make WPP the primary media steward for brands including Sprite, Fanta, and Powerade outside the U.S. and Canada. Formal announcement is expected before the end of March. IPG Mediabrands retains North America, where Coca-Cola has run UM and Initiative for nearly two decades.

The consolidation follows a quiet review initiated in Q4 2024. Coca-Cola bifurcated the work: North American media stayed put at IPG while international was opened to pitch. WPP fielded GroupM's Wavemaker and Essence teams against Omnicom and Publicis configurations. The Atlanta client prioritized data architecture uniformity and programmatic buying scale across fragmented geographies—markets where Coca-Cola often lacks the negotiating density it commands in the U.S. WPP's pitch centered on a single data spine built atop Google Cloud infrastructure, real-time attribution modeling across 14 time zones, and consolidated programmatic trading desks that currently manage over $18 billion in annual media spend globally. Coca-Cola tested the proposed stack in five pilot markets—India, Germany, Brazil, South Africa, and Japan—between November and January. Results showed double-digit efficiency gains in cost-per-completed-view and mid-single-digit lift in brand favorability velocity.

The realignment is significant for three reasons. First, it marks the rare unwinding of a multi-decade client relationship where the incumbent wasn't fired for performance failure but rather lost to structural mismatch—IPG lacked the international footprint to deliver parity. Second, Coca-Cola's move toward holdco consolidation outside North America runs counter to the last five years of Fortune 100 behavior, which favored unbundling media, creative, and data into discrete partnerships. The reversal suggests that operating at 190+ market scale still demands integrated infrastructure, even as creative work continues to fragment. Third, WPP now controls the international activation layer for a brand that spent $4.3 billion on measured media in 2023, giving GroupM material leverage in upfront negotiations and direct publisher deals across EMEA, APAC, and LATAM.

Operators should watch for three follow-on moves. WPP will likely begin consolidating Coca-Cola's programmatic buying into a dedicated trading desk by Q2, mirroring structures it built for Unilever and HSBC. That consolidation will surface pricing data from 190 markets and create benchmarking insights WPP can monetize across its CPG client base. Coca-Cola's creative agencies—which include WPP's Ogilvy in select markets but remain fragmented globally—will face pressure to align workflow and asset handoffs with the new media spine by year-end. Finally, North American brands will be watching whether bifurcated media management creates arbitrage inefficiencies or whether Coca-Cola's scale allows both holdcos to operate in parallel without friction. If the dual-holdco model holds, expect PepsiCo, AB InBev, and Nestlé to test similar splits by mid-2026.

The win adds $2.5 billion+ in annualized billings to WPP at a moment when the group reported flat organic growth in Q4 2024 and faces continued pressure from consulting firms entering programmatic buying. Coca-Cola's international footprint gives GroupM a defendable moat—no consulting practice has built comparable infrastructure across 190 markets—and positions WPP as the only holdco operating beverage media at genuine global scale. Formal announcement lands before Easter.
