IPG wins Anthropic’s US media business as the AI startup’s valuation continues to soar

IPG Mediabrands has won U.S. media duties for Anthropic, the AI startup behind the Claude chatbot, Philippe Krakowsky, Interpublic Group of Cos.’ CEO, said on its second-quarter earnings call this morning.

IPG reported a 3.5% decline in organic net revenue for the second quarter, citing prior-year client account activity. The agency holding company is still weathering the impact of losing Amazon’s massive media account in 2024. Omnicom Group’s plan to acquire IPG remains on track to close in the second half of 2025, Krakowsky said in a statement.
