The stock market rendered its verdict on agency stocks in 2025, and it wasn’t kind. WPP has plunged 62% and is dropping from the FTSE 100 after 27 years.
The 2025 Scorecard:
- WPP: -62% YTD, market cap collapsed from £24B to £3.1B, exits FTSE 100
- Publicis: -25% YTD, but analyst ratings at multi-year highs (data + AI capabilities lead)
- Omnicom: -18% YTD, IPG merger closed, world’s largest holding company
- Dentsu: Strategic review, overseas operations under evaluation
WPP’s fall is particularly instructive. The company lost a string of high-profile clients (including Coca-Cola’s US and Canada media business to Publicis), issued two profit warnings, and saw new CEO declare the previous trajectory “unacceptable.”
The Pattern: Winners invest in technology platforms and data assets. Losers optimize legacy operations. The gap compounds as AI capabilities scale.
