French payment services provider Worldline is in damage-control mode following explosive allegations that it continued servicing high-risk clients—including those linked to illegal gambling, pornography, and potential money laundering—despite multiple red flags and regulatory restrictions.
The controversy stems from a sweeping investigation by 21 European media outlets, which found that Worldline and its subsidiary Payone processed billions in transactions from clients widely considered “high-brand-risk.” These included online platforms for adult entertainment and gambling, some of which reportedly had ties to illegal activities.
According to internal documents and whistleblower testimony, even after Germany’s financial watchdog BaFin imposed restrictions on onboarding new high-risk clients in 2023, Worldline allegedly rerouted some of these clients through other parts of its corporate network to keep the business flowing.
In response to mounting public and investor pressure, Worldline has initiated a comprehensive internal review. The company has appointed Accuracy, an independent audit firm, to reassess its remaining high-risk merchant portfolio. This move is aimed at restoring stakeholder confidence and addressing concerns about weak compliance oversight.
Additionally, Oliver Wyman, a globally respected management consultancy, has been brought in to evaluate and strengthen Worldline’s internal control systems. These reviews are expected to uncover how deep the risk exposure runs and whether existing compliance measures were adequately enforced—or simply ignored.
The findings of both assessments are scheduled to be published with Worldline’s half-year financial results on July 30.
Worldline’s Chairman, Wilfried Verstraete, stated that the company began exiting relationships with questionable merchants in 2023, aiming to clean up its client base. This resulted in a loss of approximately €130 million in revenue during 2024 from the so-called “high-brand-risk” segment.
But the market reacted sharply to the revelations. Worldline’s stock plunged as much as 41% in a single day, erasing hundreds of millions in market value. The company’s credibility with investors and regulators is now in serious jeopardy.
Regulatory scrutiny across Europe is likely to intensify in the coming months. Financial authorities in Germany, Belgium, and the Netherlands are expected to take a closer look at how Worldline managed to keep high-risk clients within its network despite prior interventions.
This scandal underscores a growing dilemma in the fintech and payments space: the tension between rapid growth and regulatory compliance. Worldline’s next steps will be critical in determining whether the firm can regain trust—or whether more severe consequences await.
