## Publicis Wins Mars’ $1.7 Billion Media Account: What It Means for the Branding Landscape
In a significant shakeup in the advertising world, **Publicis Groupe** has clinched Mars’ expansive media business from **WPP**, according to insights from ADWEEK. This monumental win is more than just a transfer of accounts; it signals shifting tides in the branding and advertising ecosystem.
### A Comprehensive Media Strategy Unveiled
### **Publicis Takes the Helm**
Effective immediately, Publicis will oversee **Mars’ media, production, commerce, paid social media, and influencer marketing** efforts across a dazzling **70+ markets** globally. To ensure a tailored approach for this robust portfolio, Publicis has formed a specialized team dubbed **“OneMars.”** This initiative promises to reshape how Mars connects with consumers, emphasizing the importance of **cohesive branding and targeted media** strategies.
### **Changes in PR Leadership**
Simultaneously, Mars has entrusted its global brand PR operations to the **Interpublic Group** (IPG). The **Weber Shandwick Collective**, which has already built a relationship with Mars, will take the lead, ensuring synergy across different marketing channels.
### The Review Process: A Competitive Arena
The selection process was no small feat; spanning approximately **six months**, it included major players like Publicis, Omnicom, and the incumbent WPP. This intense competition marks one of the most significant pitches of 2025, though it’s important to note that **creative duties**, currently held by Omnicom’s **BBDO and DDB agencies**, were not included in this review.
### **Mars’ Vision for the Future**
Gülen Bengi, Mars’ Chief Marketing Officer and Chief Growth Officer for Mars Snacking, emphasized the company’s commitment to **keeping the brand dynamic and customer-centric**. “To remain iconic, we must remain in motion,” she stated, pointing to the company’s desire to place fans and communities in the “**driver’s seat**” through personalized brand experiences. The partnership with Publicis is envisioned as a stepping stone to bring this ambitious vision to life.
### **Publicis’ Innovative Approach**
Arthur Sadoun, CEO of Publicis, expressed excitement about merging the agency’s **AI capabilities** with human insights, aiming to deliver the “**next generation of brand building**” for Mars. This forward-thinking collaboration is expected to leverage data-driven strategies to enhance brand presence and consumer engagement.
### A Blow to WPP: What This Means
The loss of Mars’ media account represents another setback for **WPP**, which has been grappling with challenges since the beginning of 2025. The announcement of CEO **Mark Read’s** departure in December adds to the turmoil. Recently, WPP reported disappointing earnings and a **5% revenue dip**, forecasting further declines in 2025.
### **Transitioning Client Relationships**
Publicis’ win of Mars is particularly striking given that Mars was previously serviced by **EssenceMediacom**, which held the **$1.7 billion** account until 2022. This latest transition comes on the heels of Mars’ plans to acquire rival **Kellanova** for **$35.9 billion**, thereby expanding its vast snacking portfolio with brands like Pringles and Pop-Tarts.
### The Current Advertising Landscape
The year has not been kind to WPP; losing Mars is a continuing pattern. Earlier in 2025, WPP also lost Coca-Cola’s **$700 million** North America media business to rival Publicis, further eroding its substantial relationship with the beverage giant. Additionally, the shift of Paramount from WPP after **two decades** of partnership to Publicis has caught many by surprise and underlines the volatility of agency-client relationships.
### **Conclusion: A New Era for Branding**
As Publicis prepares to assume the mantle of Mars’ media strategy, the implications for branding are profound. This move not only reshapes Mars’ agency relationships but also signals a shift towards more data-driven and consumer-centric branding strategies.
While WPP faces challenges in turning around its fortunes, Publicis is positioning itself as a leader in modern marketing techniques, potentially reshaping how brands interact with their audiences for years to come.
