Omnicom Wins IBM's $330M Global Media Mandate

Omnicom has been appointed as IBM's new global media agency, consolidating an estimated US$330 million in annual media spend under a single holding group following a review IBM launched in December 2025.

The appointment, reported on April 9, 2026, represents one of the largest media account shifts in the technology sector in recent years. IBM's creative review remains ongoing.

Omnicom Wins IBM's Entire Global Media Business

According to COMvergence, a data research firm, IBM's global media spend reached approximately US$330 million in 2024. The mandate covers IBM's full global media planning and buying operations.

WPP Media, the incumbent agency, chose not to defend the account. The decision aligns with WPP's broader internal restructuring program, known as Elevate28. Rather than compete in the review, WPP stepped aside, leaving Omnicom to secure the account.

The IBM win follows Omnicom's recent appointment by Dyson for global media planning and buying. For Dyson, Omnicom deployed a cross-agency model using multiple Omnicom media brands, with capabilities centered on data-driven solutions, identity management, and advanced analytics.

A Wider Pattern of Technology Companies Reshaping Agency Rosters

IBM's move is not isolated. Microsoft shifted its estimated US$700 million global media account from Dentsu to Publicis within the same market cycle. Together, these two moves confirm a pattern: major technology companies are consolidating media spend with holding groups that offer integrated data platforms and AI-driven planning tools.

Why Publicis Won Microsoft's $700M Account: Data Infrastructure

Publicis secures Microsoft's $700M global media account from Dentsu, leveraging Epsilon data infrastructure. The win signals clients now consolidate spend with agencies offering integrated technology at scale.

Omnicom's Omni platform, which connects audience data, commerce signals, creator data, and connected TV (internet-connected television) optimization, has been cited as a key factor in the group's recent wins. The platform is already used by clients including Amazon, Google, Meta, TikTok, and The Trade Desk.

The Omnicom-IPG merger, which creates the world's largest media holding company, further concentrates data infrastructure and buying power within the group.

IBM's 32-Year Creative Partnership With Ogilvy Also Ends

Separately, IBM's 32-year creative partnership with WPP's Ogilvy concluded in March 2026. The relationship began in 1994, when IBM awarded Ogilvy a US$500 million advertising account. The partnership produced campaigns that spanned multiple eras of IBM's brand history.

Ogilvy declined to participate in IBM's ongoing creative review. An Ogilvy spokesperson said: "We are immensely proud of our 32-year partnership, a tenure nearly unrivaled in this industry. Together, we have built one of the world's most iconic brands through campaigns that defined eras of technological progress."

IBM's decision to run its media and creative reviews separately reflects a growing enterprise approach of selecting specialized agencies for each marketing function independently, rather than bundling all work under a single agency of record. IBM's creative review remains in progress as of the reporting date.

IBM reported US$67.5 billion in total revenue for 2025, up 8% year-over-year, alongside a US$12.5 billion generative AI book of business.
