Anonymous Whistleblower Tool

Insider knowledge and assistance can be a powerful tool to help the European Commission uncover cartels and other antitrust infringements more swiftly than might otherwise be possible and can contribute to the success of our investigations.

You as an individual can help us fight cartels and other antitrust infringements, if you report insider information on such anti-competitive practices to us. These practices, which are prohibited by EU competition law, cause considerable damage to Europe's economy.

If you have direct knowledge of business practices that you think are wrong you can help us to put things right by providing us with that information voluntarily.

The information can be facts concerning anti-competitive conduct, its circumstances, the companies and the individuals involved, that are not publicly known but are known to you. They can concern past, ongoing or future anti-competitive behaviour:
  • Anti-competitive behaviour between competitors (infringing Article 101 TFEU) such as: price-fixing; market sharing; customer allocation; limitation or control of production, markets or technical development; bid rigging; keeping products off the market or unfairly excluding competitors; etc.
  • Anti-competitive behaviour by dominant firms (infringing Article 102 TFEU) such as: excluding competitors from entering markets; imposing unfair prices or other unfair trading conditions; etc.

  • Ideally use a private device and not one provided by your employer and/or one that is connected to the employer’s network/intranet.
