Wilson said WPP’s headcount of 108,000 dropped 3.5% in the first half of 2024, marking the loss of around 3,800 roles.

Amid WPP’s challenges, Read has been upping investment in WPP’s AI and data capabilities, acquiring data clean room platform InfoSum and spending £300 million annually on proprietary AI tool WPP Open.
