Antitrust Division targets algorithmic pricing and association-backed brokerage rules in two recent actions.
The Department of Justice’s Antitrust Division continues to apply sustained pressure to the real estate industry, making clear that traditional practices—whether embedded in trade association rules or facilitated through modern pricing algorithms—will face heightened scrutiny. Two recent and unrelated actions underscore this point: a proposed consent decree addressing alleged algorithmic rent coordination among large landlords, and a statement of interest emphasizing the applicability of the Sherman Act to National Association of Realtors–backed brokerage rules.
Although the cases arise from different markets—residential rentals versus home sales—they reflect a common theme: the DOJ is reaffirming that coordination, whether explicit or tacit, analog or algorithmic, remains squarely within the reach of federal antitrust law.
Part 1: DOJ Targets Algorithmic Rent Coordination in LivCor Consent Decree
On January 7, 2025, the Antitrust Division filed a proposed consent decree to resolve its claims against LivCor, LLC, a Blackstone portfolio company, in the U.S. District Court for the Middle District of North Carolina. LivCor is one of several landlords swept into a broader DOJ enforcement action focused on alleged price coordination in residential rental markets through shared pricing software.
According to the complaint, LivCor and other defendant landlords allegedly participated in a scheme to align rental prices by sharing competitively sensitive information—such as rents, pricing strategies, and software parameters—through RealPage’s revenue management algorithms. The DOJ alleges that these practices reduced or eliminated independent pricing discretion, effectively substituting algorithmic consensus for market competition.
The proposed consent decree builds on earlier settlements with RealPage, Inc., Cortland Management, LLC, and Greystar Management Services, LLC, reinforcing the DOJ’s position that automation does not immunize anticompetitive conduct.
If approved, the decree would require LivCor to:
- Refrain from using pricing algorithms that rely on competitors’ nonpublic, competitively sensitive data or that incorporate anticompetitive features;
- Cease sharing competitively sensitive information with competitors;
- Accept a court-appointed monitor if it uses uncertified third-party pricing software;
- Avoid RealPage-hosted meetings involving competing landlords; and
- Cooperate with the government’s ongoing prosecution of remaining defendants.
Assistant Attorney General Abigail Slater emphasized that the enforcement action applies settled antitrust principles to modern technology:
“Landlords across America are on notice that the competition laws protect renters from the harms caused by competitors sharing competitively sensitive information or aligning prices, whether through an algorithm or otherwise.”
Not everyone believes the DOJ is going far enough because, for example, it effectively allows the use of public information to set prices. See our previous post.
For landlords, private equity sponsors, and proptech providers, the message is clear: algorithmic pricing systems that function as conduits for coordination may create Section 1 exposure, even absent explicit price-fixing agreements.
Part 2: DOJ Weighs In on Broker Commission Litigation Against NAR
In a separate development, the Antitrust Division filed a statement of interest in Davis et al. v. Hanna Holdings Inc., pending in the U.S. District Court for the Eastern District of Pennsylvania. The case was brought by homebuyers alleging that real estate brokerages and the National Association of Realtors (NAR) entered into anticompetitive agreements that inflated broker commissions and, by extension, home prices.
While taking no position on the ultimate outcome of the litigation, the DOJ underscored several key legal principles with potentially broad implications for trade associations and their members.
First, the statement emphasizes that competition among real estate brokerages is essential to protecting consumers—particularly in a market where Americans spend roughly one-third of their household budgets on housing. Despite significant technological change, U.S. broker commissions have remained remarkably stable at approximately 5% to 6%, a level the DOJ notes is two to three times higher than those observed in other developed economies.
Second, the DOJ reaffirmed that trade association rules are not exempt from antitrust scrutiny. Courts have long recognized that association rules can violate Section 1 of the Sherman Act when they unreasonably restrain competition among members. Where such rules embody agreements among competitors, they may be challenged like any other horizontal restraint.
Importantly, the DOJ rejected the notion that association rules receive automatic protection from per se treatment. As the statement explains, rules that function as mechanisms for horizontal price fixing may still be deemed illegal per se, depending on their purpose and effect—regardless of their formal adoption by a trade organization.
“Purchasing a home is the single biggest purchase most Americans make in a lifetime,” AAG Slater stated. “Today’s soaring housing prices make competition in real estate brokerage more important than ever.”
Common Threads and Practical Takeaways
Viewed together, these actions illustrate a consistent enforcement posture. The DOJ is less concerned with the form of coordination than with its effect. Whether competitors allegedly aligned pricing through informal discussions, trade association rules, or sophisticated algorithms, the analysis remains grounded in traditional Sherman Act principles.
For real estate professionals and their counsel, several lessons stand out:
- Trade association participation carries antitrust risk when rules or norms affect price competition or constrain independent decision-making.
- Algorithmic tools are not liability shields. Sharing competitively sensitive data—even indirectly—may support an inference of unlawful agreement.
- Housing markets remain an enforcement priority, particularly given inflationary pressures and heightened political sensitivity around affordability.
As the Antitrust Division continues to advance these theories in court, real estate firms should reassess compliance programs, data-sharing practices, and reliance on shared pricing technologies. The DOJ has made clear that long-standing industry practices will not escape scrutiny simply because they are familiar—or technologically sophisticated.
