Antitrust Agency Insights: Developments at the U.S. Antitrust Enforcement Agencies — First Quarter 2024


Letter From the Editors

Successfully navigating antitrust agency investigations requires a familiarity with Department of Justice and Federal Trade Commission processes, as well as insight into those agencies and their leaderships’ current priorities for enforcement and competition policy. This newsletter will provide periodic updates on both, offering an analytical look at how the antitrust agencies are approaching important competition issues and what current investigations may mean for potential future enforcement. We hope our experience — both inside and outside these agencies — will provide insights that help you make more informed decisions for your business.

DOJ Warns That Artificial Intelligence and Algorithmic Information Sharing May Lead to Criminal Liability

On February 15, 2024, the Section Chief of the Washington Criminal I Section of the Department of Justice’s Antitrust Division (DOJ) warned companies that they could face criminal liability for improperly sharing information with competitors. According to DOJ leadership, the development of artificial intelligence (AI) and advanced algorithms has increased the danger that information that previously would not have raised concerns may be weaponized to decrease competition. The warning, which took place at an American Bar Association panel,1 provides insight into the antitrust agencies’ approach to antitrust enforcement as companies increasingly use new technologies to assist them in their businesses.

Comments on Risk of Criminal Liability for Companies Using AI or Algorithms To Exchange Information

On February 15, 2024, Ryan Tansey, the Section Chief for the DOJ’s Washington Criminal I Section, warned companies that the DOJ was closely investigating the use of AI and algorithms that previously escaped scrutiny (referring to the previously withdrawn joint DOJ/Federal Trade Commission policy statements providing safe harbors for information sharing in certain contexts).2 While the withdrawn policy statements indicated that the agencies were unlikely to challenge information exchanges that involved anonymized data from at least five firms that was at least three months old, Tansey suggested that the use of AI has now created a situation where companies can utilize a tremendous amount of what would have previously been considered stale and aggregated data for anticompetitive purposes. Given this development, he stated that the DOJ has expanded the scope of markets it is criminally investigating, emphasizing that small companies and members of decentralized markets now need to reassess their criminal antitrust exposure.

Tansey emphasized that, as in all criminal investigations, the DOJ is still focused on intent. In the AI or algorithmic pricing context, that means an agreement with a competitor to use the same algorithm and to share price or other sensitive information. Intent can also be shown where a company discovers that an algorithm it uses may allow it to collude with competitors. He revealed his section had opened quite a few grand jury investigations since he took over his role in July 2023, and the DOJ is using more covert methods of investigation, including wiretaps and undercover operations, to reveal evidence of intent.

The DOJ, Tansey noted, also identifies potential AI and algorithm investigations from a variety of sources. Tansey commented that the DOJ has opened inquiries based on facts learned during merger investigations and from citizen complaints, public information, and private cases. In at least one instance, an inquiry was opened because a DOJ economist identified parallel price movements in data that appeared contrary to natural market movements. Not all cases may amount to a per se unlawful agreement to fix prices, but companies and individuals could still face civil liability under a rule-of-reason analysis of the conduct at issue. He also warned that, historically, the DOJ has seen a number of information exchanges that may have started out innocuously, but eventually turned into a price-fixing arrangement as competitors’ conduct evolved.


Tansey’s statements are significant because they come at a time of increasing interest in AI and algorithms, with no formal agency guidance on how companies can share information without running afoul of the antitrust laws. In addition to DOJ enforcement against information exchanges, private plaintiffs have brought suits alleging algorithms have enabled price-fixing agreements in the real estate and hotel industries,3 and the DOJ has filed statements of interest supporting plaintiffs.4 The statements of interest argue the use of pricing algorithms and agreements with the algorithm provider to share confidential data are tacit agreements among the algorithm users sufficient to establish a conspiracy under Section 1 of the Sherman Act.5 While circumstantial evidence of a conspiracy often requires parallel conduct and certain “plus factors,” the statements take the position that an agreement can be inferred from an invitation proposing collective action followed by a course of conduct showing acceptance.6 The Federal Trade Commission (FTC) and DOJ contend these arrangements are per se violations as agreements to use the same pricing formula and that, even if competitors deviate from the suggested prices, “competitors cannot agree to fix the starting point for price,” just as they cannot fix the final price.7

The statements of interest and public comments reflect a warning from agency leadership that any AI or algorithmic programs that incorporate sensitive data from competitors is suspect, regardless of the precautions taken to aggregate data or wait until the data becomes stale. Practices that may have been covered by a safe harbor under now-withdrawn guidance could now lead to criminal charges or civil enforcement. As a result, companies need to reassess their risk when using AI or algorithmic tools, especially when those tools incorporate information from competitors. Proper compliance and additional training for employees may be necessary in this area.
