The Department of Justice's Antitrust Division, alongside several states, has formally filed its response to public comments concerning the proposed Final Judgment in the landmark antitrust case, United States et al. v. RealPage, Inc. et al. Filed in the U.S. District Court for the Middle District of North Carolina, this response signals the government's intent to move for the entry of the proposed judgment after careful consideration of eight public submissions. The central thrust of the case revolves around allegations that RealPage, a leading provider of revenue management software for multifamily rental housing, engaged in anticompetitive practices that harmed consumers and stifled competition within the rental market.
The Heart of the Antitrust Allegations
The civil antitrust Complaint, initially filed in August 2024 and amended in January 2025 to include six property management companies as defendants, outlines two primary claims under the Sherman Act. First, the Complaint alleges violations of Section 1 of the Sherman Act, 15 U.S.C. 1. This section targets unlawful agreements among competitors. Here, the government asserts that RealPage and the landlord defendants unlawfully agreed to share and utilize competitively sensitive information, and further, to align rental pricing through RealPage's proprietary software products, including AI Revenue Management (AIRM), YieldStar, and Lease Rent Options (LRO).
The Complaint details how RealPage's software, by design, facilitated price alignment. Landlords utilizing AIRM or YieldStar, it is argued, effectively synchronized their pricing processes and strategies for setting rents, pricing amenities, and managing occupancy. The government cites internal communications where the phrase "a rising tide rises all ships" was used to describe how RealPage's tools would cause prices to move in a "similar manner" across the market. The sharing of nonpublic, competitively sensitive data, used to train RealPage's algorithmic models, is central to these Section 1 claims, positing that it directly harms competition, renters, and prospective renters.
Second, RealPage faces charges under Section 2 of the Sherman Act, 15 U.S.C. 2, for monopolizing or attempting to monopolize the commercial revenue management software market for conventional multifamily rental housing. The government alleges that RealPage leveraged its licensing agreements with landlords to amass an extensive database of competitively sensitive information. This massive data reservoir, according to the Complaint, obstructs other software providers from effectively competing on merit, as they cannot access comparable data without entering similar agreements, thus harming the competitive process.
The Proposed Final Judgment: Restoring Competition
To remedy the alleged loss of competition, the proposed Final Judgment imposes a series of stringent requirements and restrictions on RealPage. These measures are designed to fundamentally alter how RealPage operates and interacts with landlord data and pricing strategies:
-
Restrictions on Data Use: The judgment distinguishes between "runtime operation" (landlord's use of software for specific property pricing) and "model training" (analyzing data to create algorithms). RealPage will be prohibited from using nonpublic data from competing properties during runtime operation, with limited exceptions. For model training, only backward-looking data, aged at least 12 months and not derived from active leases, will be permissible.
-
Limitations on Information Sourcing and Sharing: RealPage will face significant constraints on its ability to obtain and disseminate nonpublic information among landlords. This includes prohibitions on using, sharing, publishing, or disclosing competitors' nonpublic data to a landlord, even through its own revenue management products or pricing advisors. Crucially, RealPage must cease conducting market surveys (collecting competitively sensitive data via calls or emails) for its revenue management products or price recommendations for the duration of the judgment. Furthermore, it cannot discuss or facilitate discussions among landlords regarding market analyses, trends based on nonpublic data, or pricing strategies.
-
Geographic Limitations for Model Training: To prevent localized price collusion through algorithms, RealPage's AI Demand, AI Supply I, and AI Supply II models cannot be trained with a geographic variable narrower than a state. Any future models utilizing nonpublic, competitively sensitive data will be restricted to a national geographic variable.
-
Software Feature Modifications: The judgment mandates changes to RealPage's software to ensure landlords retain independent pricing control. RealPage cannot prohibit or impede a landlord's ability to reject or override a recommended price. Any automatic price acceptance features must require individual parameter settings by landlords. Price increase and decrease limits must be symmetrical, with landlords individually determining these thresholds.
-
Robust Compliance Measures: A monitor, selected by the United States, will oversee RealPage's compliance for a minimum three-year term, with potential extensions. RealPage must also implement a written antitrust compliance policy and provide training to its employees. The United States will retain rights to inspect documents and interview employees to ensure adherence to the judgment. RealPage is also required to cooperate with the United States in its Section 1 claims against the non-settling landlord defendants.
DOJ Upholds Proposed Remedies After Public Review
Despite receiving eight public comments, the United States has affirmed its belief that the proposed Final Judgment provides an effective and appropriate remedy for the antitrust violations alleged. The Department of Justice maintained that its response, like previous filings under the Tunney Act, focuses on the United States' claims, which are the sole claims to be resolved by this specific judgment if entered. The comments themselves were made public on the Antitrust Division's website, an approach approved by the Court to ensure accessibility while managing publication costs.
Implications for the Rental Housing Market
The potential entry of this Final Judgment carries significant implications for the broader conventional multifamily rental housing market. For renters, the intent is to foster a more competitive environment, potentially leading to more competitive and independently determined rental prices. Landlords, particularly those utilizing RealPage's software, will need to adapt to new operational parameters regarding data sharing and pricing decision-making. The judgment underscores the federal government's increasing focus on algorithmic pricing and data-driven collusion, signaling a proactive stance against practices that could lead to tacit or explicit price coordination in various industries. The ongoing cooperation from RealPage in the government's pursuit of claims against the non-settling landlords suggests that this case may continue to shape the landscape of antitrust enforcement in technology-driven markets.
