2025 Ad Tech: Mergers, Mayhem, and Privacy Shifts
2025 in ad tech was defined by a wave of consolidation, high-stakes M&A, and shifting regulatory and privacy dynamics. Omnicom announced it would acquire IPG in a roughly $25B deal, drawing FTC scrutiny before receiving European Commission clearance and prompting a large restructuring that includes thousands of job cuts. Equativ merged with Sharethrough to form one of the largest independent ad tech platforms outside the walled gardens, expanding reach across CTV, programmatic, and supply optimization. Publicis augmented its data capabilities by acquiring Lotame, valuing in part its 1.6 billion user profiles and folding them into the Epsilon stack. In media, Paramount bid $108.4B for Warner Bros Discovery, with Netflix offering about $72B, while the board signaled it would reject Paramount’s bid. The year also saw TikTok’s fate tied to a Trump order to transfer US ownership to American investors, plus a binding deal with Oracle, Silver Lake, and MGX that could yield a US JV in 2026. Google faced antitrust actions and Privacy Sandbox momentum faded, even as AI reoriented traffic away from publishers.
