Britain's top financial regulator is investigating three of the world's largest payment companies—PayPal, Visa, and Mastercard—over potential anti-competitive behavior linked to PayPal's digital wallet. The Financial Conduct Authority (FCA) confirmed the probe on May 6, 2026, examining if the firms created unfair conditions for using the popular online payment service.
"Visa is cooperating with the FCA in its inquiry," a spokesperson for the company told FStech. Both Mastercard and PayPal have also confirmed their cooperation with the regulator, which stressed that it has not yet reached any conclusions.
The investigation centers on potential breaches of the UK's Competition Act 1998. All three firms are being scrutinized under Chapter I, which covers agreements that may restrict competition. Visa and Mastercard face an additional investigation under Chapter II, which relates to the possible abuse of a dominant position in the market.
The probe creates significant legal and financial uncertainty for the payment giants, which collectively process trillions of dollars in transactions annually. If found in breach, the companies could face substantial fines and be forced to alter their business practices in the UK, a key global market.
The FCA's move follows a disclosure by PayPal in its quarterly financial reporting in the US, which stated the investigation began in March of this year. The regulator's public confirmation is unusual, as it typically waits until it issues a formal statement of objections.
In a statement, a Mastercard spokesperson said: “We can confirm that we’ve received an information notice from the FCA requesting details of our contractual relationship with PayPal. Mastercard works to ensure we meet the highest standards of competition law and will be cooperating fully and transparently with the FCA.”
PayPal's spokesperson offered a similar sentiment, stating, "PayPal is cooperating with the FCA. As this is a pending investigation, we cannot comment further at this time." The investigation highlights the growing regulatory scrutiny on the rapidly evolving fintech and payments sector, where a few large players hold significant market power.
