WPP's China ad-buying arm ran a ¥1.2 billion kickback scheme before anyone noticed
GroupM China's investment chief steered ad spend to brokers who kicked back $176M. Shanghai police raided the office; WPP fired him and cut ties with the firms.

What happened
GroupM, WPP's global media-buying network, ran its China ad-placement business through a chief investment officer who controlled which brokerage firms received client ad spend. Investigators found that role had been used for years to route business to firms that kicked money back to him and two colleagues — roughly ¥1.2 billion (about US$176 million) in total.
Shanghai's economic investigation police raided GroupM's Shanghai office in early 2024. WPP said it was cooperating with authorities, fired the executive, suspended trading with any outside organisation understood to be part of the police inquiry, and brought in a third-party firm to run an internal investigation.
A Chinese court convicted the three former executives in 2026, following the scheme's exposure through the 2024 raid. WPP, which was not itself a party to the proceedings, said only that it respected the court's decision — but the case exposed how little visibility the London-based parent had into how its China ad-buying unit actually allocated client spend.
Why it happened
- A single executive controlled which brokers received client ad budgets for years, with no internal check that caught the kickback flow before police did
- WPP's compliance and audit structure sat above the country unit rather than inside its day-to-day media-buying decisions, a gap regulators had flagged before over other high-risk markets
- the scale — ¥1.2 billion moving through brokerage relationships — shows how much volume a media-buying kickback scheme can reach before anyone outside the unit notices
The lesson
Media-buying runs on trusted discretion over where client money goes — when the only check on that is the person exercising it, a kickback scheme runs for years before an outside raid finds it.
Aftermath
The case pushed advertisers to press harder for transparency in China media-buying practices industry-wide. WPP's new leadership cited the episode in describing tightened compliance controls across its high-risk-market subsidiaries.
