A £737K Payout: DOJ's New Whistleblower Program Triggers Antitrust Shockwaves

The U.S. Department of Justice (DOJ) Antitrust Division has seen the first-ever whistleblower payment under a newly developed rewards programme, which heralds a major change in the way criminal antitrust offences should be understood as a way of exposing and prosecuting them.

The ~737,000 (£$1 million) milestone payout reflects a larger initiative to encourage insiders to disclose covert anticompetitive behaviour damaging consumers and markets.

A New Tool in Antitrust Enforcement

The United States Postal Service (USPS) worked with the DOJ Antitrust Division to award the first whistleblower under the Whistleblower Rewards Programme on 29 January 2026.

This programme, which opens in July 2025, enables individuals to have monetary compensation to offer their original and valid information that results in a successful action of enforcement, whether in terms of criminal fines or at least 1 million dollars in entry.

Whistleblowers who achieve the results of criminal enforcement due to their voluntary report under the programme might receive a reward of up to 30 per cent of the monetary recovery. Employees are also guarded by the federal law against retaliation in case of reporting criminal antitrust violations by the employer.

According to Assistant Attorney General Abigail Slater, the programme was intended to help crack the secrecy that usually surrounds anticompetitive conspiracies in encouraging insiders who had first-hand knowledge of their existence report them.

The First Case: EBLOCK Bid-Rigging Scandal

The initial award was based on the leaked information that aided the federal prosecutors in initiating criminal charges against EBLOCK Corporation, which is an online auction site that deals in used cars.

Court documents indicate that EBLOCK entered into another auction business in November 2020 but was unable to stop a current bid-rigging and conspiracy scheme of fraud, in which workers in both companies conspired to overcharge and stifle competition.

Such practises, which it reportedly did all as far back as February 2022, consisted of fraudulent activities including so-called shill bidding, where spent bids artificially elevated the sale price to legitimate bidders.

As a condition of the resolution, EBLOCK admitted to a criminal fine of $3.28 million and selected a Deferred Prosecution Agreement (DPA) with the Antitrust Division. The initial tip given by the whistleblower was credited with the help of which prosecutors were able to take this enforcement action.

As a reward, the DOJ and the USPS gave the payout of 1 million dollars, the first to be given out under the programme.

Greatest Disinfectant: Officials on the Impact

Deputy Assistant Attorney General Omeed A. Assefi referred to whistleblowers as one of the greatest disinfectants to the Justice System in respect to unharvested criminal antitrust plots.

According to Assesifi, the award not only celebrates the effort of the person in discovering the EBLOCK conspiracy, but it also puts forward the importance of the role played by the whistleblowers in the future enforcement implementation.

Even the actuarial Director of Criminal Enforcement, Daniel Glad, added that whistleblowers who submit actionable and novel information could receive substantial awards.

This would apply even if the underlying criminal activity had already been closed.

He explained that rewards were not limited to tips that initiated new investigations.

They could also be granted for information that was substantive and helped achieve successful results.

The programme was also commended by the Federal Bureau of Investigation (FBI) and the U.S. Postal Inspection Service, where the collaboration helped in putting an end to misconduct that had caused direct harm to American consumers by increasing the price in the used vehicles market.

A Strategic Shift In Enforcement

According to experts, the programme is a significant strategic move by the DOJ Antitrust Division, which has long been relying on companies to find their own way to report violations unless they want to face prosecution as part of its corporate Leniency Policy.

By that old system, the first company to complain of cartel activity prior to the initiation of an investigation may be granted protection of non-prosecution.

Nonetheless, the new whistleblower bonuses bring about a similar competition of race to the reporting, wherein people are encouraged to turn over organisations or companies to the Justice Department before other organisations or companies do.

The programme may assist in uncovering complex anticompetitive conspiracies undetected in the absence of a focus on the value of original, detailed information and timeliness, which would be caught by the prosecutors when a specific case is reviewed.

Businesses and Markets Implications

The implementation of the whistleblower rewards programme will have far-reaching effects, especially in those industries where collusion and bid-rigging have proven to be very challenging to establish.

Legal commentators have suggested that it may lead to changes in internal compliance behaviour, and that companies could now face lawsuits from employees who choose to file claims outside the organisation.

Some employees may do so in the hope of qualifying for a financial award. This could happen instead of seeking leniency through corporate self-disclosure systems.

Whistleblowers have to satisfy close criteria in order to receive a payout: they need to present original information unavailable to the enforcers, and the action case must lead to fines or recoveries that are at least one million dollars.

The Department also focuses on the pivotal element of confidentiality and anti- retaliation, where a whistleblower is ensured security against retaliation by the employer.
