The Department of Justice’s Antitrust Division, in partnership with the U.S. Postal Service, has launched a Whistleblower Rewards Program to combat antitrust crimes. Following the DOJ Criminal Division’s launch of a whistleblower pilot program last year,1 the Antitrust Division is now offering a reward to whistleblowers. Under the new program, individuals who report credible and timely evidence of antitrust collusion—such as price-fixing or bid-rigging and certain monopolization cases—may receive up to 30% of recovered criminal fines. This marks a significant step in expanding detection tools for antitrust violations, with reports to be submitted through a dedicated DOJ webpage.
