Omnicom's Commerce Empire: How AI and Acquisitions Forged a Market Leader

NEW YORK, NY – February 17, 2026 – Marketing giant Omnicom has been officially crowned a leader in commerce services, a recognition that validates a deliberate and high-stakes strategy years in the making. In its newly released “The Forrester Wave™: Commerce Services, Q1 2026” report, independent research firm Forrester placed Omnicom at the top of the pack, a position built not overnight, but through a series of aggressive acquisitions and the deep integration of artificial intelligence into its core offerings.

The accolade is far from a simple pat on the back. Within Forrester's rigorous 23-point evaluation, Omnicom achieved the highest possible scores in 18 criteria, a near-dominant performance. The top marks span a wide array of modern marketing imperatives, from AI-powered commerce strategy and retail media activation to CRM design and global delivery strategy. This distinction solidifies the company’s pivot from a traditional advertising holding company to an integrated, technology-driven powerhouse poised to define the next era of digital and physical retail.

The Architects of a Commerce Juggernaut

Omnicom's leadership status is the direct result of a calculated, multi-billion dollar campaign to construct an end-to-end commerce ecosystem. The foundation of this strategy was laid with two transformative acquisitions that have been systematically integrated to create a formidable market advantage.

In early 2024, Omnicom closed its acquisition of Flywheel Digital for approximately $835 million. The move was a seismic event in the industry, instantly establishing Omnicom as one of the world's largest buyers of retail media, with a portfolio now exceeding $10 billion in managed spend. More importantly, the deal brought the Flywheel Commerce Cloud—a massive repository of digital transaction data—into the fold. This gave Omnicom unprecedented visibility into sales and performance across hundreds of global marketplaces, including giants like Amazon, Walmart, and Alibaba.

Just over a year later, in November 2025, Omnicom moved to secure the other side of the commerce equation: consumer identity. It acquired Interpublic's Acxiom Real ID™, gaining access to what is described as the industry’s largest and most ethically sourced identity graph, encompassing 2.6 billion verified global IDs. This provided the critical link between anonymous transaction data and real-world consumer identity, enabling a far more granular and comprehensive understanding of customer behavior.

Omni: The AI-Powered Intelligence Engine

These powerful data assets are not siloed. They serve as the fuel for Omni, Omnicom’s proprietary AI-driven marketing intelligence platform. Relaunched in its next-generation form earlier this year, Omni acts as the central nervous system connecting the company's vast capabilities. It fuses the verified identity data from Acxiom with the real-time transaction and product signals from Flywheel Commerce Cloud, enriching it further with trillions of other data points related to media, content, and culture.

This integration provides Omnicom’s teams and clients with a unified, reliable view of the consumer journey. According to the company, this “single source of truth” eliminates the data fragmentation and operational friction that often plague large marketing campaigns. The platform’s AI layer analyzes this immense data pool to surface insights, recommend optimizations, and automate workflows, from initial strategic planning and creative development through to media buying and performance measurement.

In the press release announcing the Forrester recognition, Omnicom Chairman and CEO John Wren underscored this strategic advantage. "With the integration of Flywheel and Acxiom into our commerce capabilities, we've built the industry's most powerful intelligence engine that will help our clients transform every consumer touchpoint into a driver of measurable sales growth," he stated. This reflects a core shift where AI is not just an add-on but the fundamental operating system for delivering client results.

Dominating the Exploding Retail Media Market

Omnicom's strategy has proven particularly prescient in the context of the retail media boom. Now considered the third pillar of digital advertising alongside search and social, the global retail media market was projected to exceed $179 billion in 2025 and continues to show explosive growth. This channel is prized for its reliance on rich, first-party data and its ability to provide “closed-loop” attribution—directly linking ad spend to sales—a holy grail for marketers, especially as third-party cookies are phased out.

With over $10 billion in retail media under its management, Omnicom is not just a participant in this market; it is a primary force shaping it. The Forrester report specifically highlights the company's excellence in “retail media activation, buy, and run.” Deep partnerships with key players like Amazon, Walmart, Target, and TikTok Shop give its clients preferential access and advanced strategic capabilities. This scale and integration allow brands to navigate the increasingly complex and fragmented landscape of digital marketplaces, ensuring their products are visible and their ad dollars are effective at the digital point of sale.

Forrester's analysis noted that Omnicom's vision for “connected commerce” is a key differentiator, as it successfully bridges the gap between driving demand and fostering loyalty across physical stores, online marketplaces, and direct-to-consumer channels.

A New Blueprint for Agency Services

Ultimately, the Forrester Wave™ recognition is a testament to a broader industry transformation that Omnicom is leading. The report highlights praise from customers for the company’s ability to perform as a “single agency,” granting them access to a vast and diverse talent pool under one integrated umbrella. One client sentiment noted in the report acknowledged, "it's unlikely they will encounter a challenge Omnicom hasn't already tackled."

This feedback points to the success of Omnicom’s holistic model, which combines its world-class creative agencies with the data prowess of Acxiom, the commerce execution of Flywheel, the media buying scale of its media groups, and the technology consulting of firms like Credera. For clients, this means a single strategic partner can address complex growth priorities that cut across marketing, sales, and technology without the need to stitch together multiple, often competing, vendors.

By investing heavily in a proprietary tech and data stack and integrating it deeply into its service offerings, Omnicom has created a powerful, defensible moat. This integrated approach, validated by Forrester's top ranking, provides a blueprint for the future of marketing services, where success is defined not by the individual services offered, but by the ability to connect them all into a seamless engine for client growth.
