Britain’s Financial Conduct Authority announced on Wednesday that it is investigating three major payment companies for suspected anti-competitive behavior.

The FCA said it is looking into Mastercard, Visa, and PayPal. The probe is focused on how PayPal’s digital wallet is funded and used by consumers.

The regulator released a brief statement confirming the investigation. It was careful to note that no conclusions have been reached and no findings have been made about whether any competition law has actually been broken.

The FCA is the UK’s main financial regulator. It has the power to investigate and penalize companies that break competition rules in financial markets.

PayPal operates one of the most widely used digital wallets in the world. Mastercard and Visa are the two largest card payment networks globally.

PayPal Holdings, Inc., PYPL

What the Probe Is Looking At

The investigation centers on the relationship between the three companies and how that relationship affects how PayPal’s wallet works for consumers.

The FCA has not released detailed specifics about what conduct it suspects may be anti-competitive. The statement was short and offered limited detail beyond confirming the probe exists.

Anti-competitive conduct in payment networks can include things like pricing arrangements or agreements that limit consumer choice. It is not yet clear which of these areas the FCA is focusing on.

All three companies saw their share prices drop following the announcement. PayPal fell the most, dropping around 7.74%. Mastercard fell about 1.52% and Visa dropped roughly 1.47%.

Where Things Stand

The investigation is in its early stages. The FCA has not accused any of the three companies of wrongdoing.

Under UK competition law, companies found guilty of anti-competitive conduct can face large fines. They can also be ordered to change how they operate.

Mastercard, Visa, and PayPal have not yet made public statements responding to the probe.

The FCA did not give a timeline for when it expects to complete its investigation.

This is the most recent information available as of May 6, 2026, the day the FCA made its announcement.
