Microsoft named Publicis Groupe as its global media agency of record, in a move that expands their partnership and deepens ties around AI.
Microsoft’s media account, which was previously held by Dentsu, was reportedly won by Publicis without a pitch. Dentsu will continue to control the media planning and buying for Xbox, AdWeek reported.
The account is estimated to be worth around $700 million in annual media spend, according to COMvergence.
Microsoft and Publicis had previously partnered for the development and rollout of Marcel, Publicis’ AI platform. The expanded partnership will include the modernisation of legacy systems alongside AI agent deployment. Publicis will also deploy Microsoft 365 Copilot to its more than 114,000 employees worldwide.
Powering Agentic AI
Both companies are set to utilise the expertise of the other, with Publicis Sapient’s agentic AI platform Slingshot set to make use of Microsoft’s cloud computing platform Azure to migrate legacy systems and build foundations for AI adoption.
A key aspect of the partnership is the building of AI agents on top of Publicis’ Epsilon platform, which creates a data layer using identity, media, marketing, and customer intelligence. Using Microsoft Fabric – the tech giant’s platform that organises and unifies data – as a data layer, agents will be able to reason and carry out tasks autonomously.
An agent would be able to automatically identify the best customer segments to target, generate ad content, personalise that content, and launch it on channels – all autonomously.
Holding Companies as Tech Partners
The move reflects a broader industry shift towards “agentic AI”, where autonomous systems can execute end-to-end marketing tasks rather than simply assist humans. It also signals a deeper convergence between media, data, and enterprise AI – where holding companies become end-to-end tech partners for clients.
“Ten years ago with Microsoft we co-created Marcel, marketing’s first AI platform,” said Arthur Sadoun, CEO, Publicis Groupe. “Now we’re partnering again to shape the industry, this time as our clients confront the dynamics of the agentic era.”
