Omnicom Named a Leader in Gartner Agency Rankings

Omnicom has announced that it has been ranked first across all evaluated categories in the 2026 Gartner Critical Capabilities for Global Digital Marketing Agencies report. 

These categories included Global Brand / Marketing Campaign Execution, Omnichannel Content Creation, AI-Driven Marketing Innovation, Data-Driven Performance Marketing, Digital Commerce and CX Overhaul, B2B Marketing and Website and Digital Product Design. 

The agency was also recently named a leader in the 2026 Gartner Magic Quadrant for Global Digital Marketing Agencies, alongside the likes of VML and DEPT. 

According to Omnicom, this recognition can be largely attributed to its technological advancements, with the company saying its expertise in marketing technology strategy, organisational design and change management, complemented by its AI and data capabilities, has played a key role in helping its clients bring in new marketing solutions and make meaningful transformations.

Gartner’s Critical Capabilities report took several factors into account over the course of its evaluation – such as the clarity of the organisation’s AI vision, the depth of capabilities in its creative execution, its martech strategy, content supply chain optimisation, first-party data enrichment and digital marketing performance. 

For Omnicom, a significant part of that strategy is the development of Omni, its AI-enabled intelligence platform. 

This brings together data, AI, commerce intelligence, Omnicom’s marketplace access and cultural signals, among other factors, together onto one platform to give its clients a foundation where they can connect strategy, execution and performance across the entire marketing ecosystem 

“Our ranking in Gartner’s Critical Capabilities report and our Leader position in the Magic Quadrant reflect Omnicom’s commitment to delivering AI‑powered, data‑driven marketing solutions at scale,” says Paolo Yuvienco, Chief Technology Officer of Omnicom. 

“This recognition validates the value that our investments in Omni as well as our data, identity and AI solutions are delivering to Omnicom’s clients. 

“We are proud to be leading the market in the future‑facing tools and capabilities shaping modern marketing.”

Growth at Omnicom

This ranking is the latest step in a strong year of growth for the agency. 

In August 2026, Omnicom was named the agency of record for Novo’s US media account – with the healthcare company bringing its long-standing partnership with WPP to an end. 

Under a year ago, in November 2025, the company also acquired Interpublic Group (IPG) in an all-stock transaction valued at around US$9bn – making Omnicom the world’s largest advertising and marketing holding company. 

Over the past twelve months, the company has generated US$22.37bn in revenue, with sales for its second quarter of 2026 reaching US$6.56bn – rising 63.4% year on year.

“We are built for an era where speed, integration and scale matter most,” says John Wren, CEO of Omnicom. “Our wins this quarter demonstrate that. Clients are consolidating more work with us because they see the competitive advantage our connected capabilities deliver. 

“Looking ahead, we will strengthen our position as an integrated growth partner by focusing on three key areas: leading in agentic marketing transformation, expanding and deepening our partnerships with existing and new clients and helping clients win across the new consumer engagement models in sports & entertainment, social & creator, connected commerce and AI-driven discovery.”
