Justice Department decree would cut one of America's largest landlords off from pricing software trained on rivals' data

The Antitrust Division of the United States Department of Justice published a proposed Final Judgment and a Competitive Impact Statement on 18 September 2026, at 91 FR 59304, in the case captioned United States of America, et al. v. RealPage, Inc., et al. The notice runs 48 pages under document number 2026-19100. It carries no regulation identifier number: it is a Tunney Act notice, not a rulemaking.

It binds a single defendant: Pinnacle Property Management Services, LLC, a Delaware company headquartered in Frisco, Texas, and a subsidiary of Cushman and Wakefield, which the government describes as one of the largest apartment managers in the United States. The case is Civil Action No. 1:24-cv-00710 in the United States District Court for the Middle District of North Carolina. The plaintiffs alongside the United States are North Carolina, California, Colorado, Connecticut, Illinois, Minnesota, Oregon, Tennessee, Washington and the Commonwealth of Massachusetts.

The original complaint against RealPage was filed on 23 August 2024 and amended on 7 January 2025 to add Pinnacle and five other property managers. The proposed judgment was filed on 4 September 2026 and binds none of the other defendants, among them RealPage, Inc., Camden Property Trust, Greystar Real Estate Partners and Willow Bridge Property Company.

What the judgment actually bars

The core prohibition switches on 180 days after entry of the Stipulation and Order. From that date, under Paragraph IV.A.1, Pinnacle must not license or use any Revenue Management Product that uses external nonpublic data in its runtime operation, pools nonpublic data across different property owners, discloses a Pinnacle property's nonpublic data to a third-party landlord, or contains or uses a pricing model trained on nonpublic data other than that of the subject property's owner.

Paragraph IV.A.2 adds two more bans: on any product incorporating a rental price floor or a limit on recommended price decreases that Pinnacle or the owner did not set by hand, and on any product that requires Pinnacle to accept recommended rents or pays it to do so.

Paragraph II.O sets the regulated category.

"Revenue Management Product(s)" means any software or service, including software as a service, that generates rental prices or rental pricing recommendations for multifamily housing rentals. For avoidance of doubt, a Revenue Management Product does not include general purpose spreadsheet software like Microsoft Excel.

The judgment then separates two things. Model Training, at Paragraph II.F, is "the process of analyzing data, including by machine learning or regression analysis, to create or adjust the parameters of a model or algorithm to improve the accuracy of the model's or algorithm's predictions." Runtime Operation, at Paragraph II.P, is any action a product takes while it runs, and expressly is not Model Training. Both are restricted, so a product cleaned of rival data at the moment it prices an apartment is still barred if rival data shaped its parameters.

Pinnacle licensed AIRM, or AI Revenue Management, and YieldStar from RealPage. The Competitive Impact Statement says AIRM "leverages confidential, competitively sensitive data collected from competing landlords as a critical input to generate pricing recommendations for competing landlords," drawing on leases, renewal offers and occupancy projections pulled from software such as RealPage's OneSite or Yardi's Voyager.

A monitor only if the software is not certified

The department's release and the judgment do not describe the monitorship the same way. The release lists accepting a court-appointed monitor for third-party pricing algorithms among the requirements. The judgment is narrower: Paragraph VIII says Pinnacle "will not be subject to a Monitor if all Revenue Management Products that Defendant licenses or uses at Defendant Properties have been certified pursuant to, or are otherwise compliant with, Paragraph IV.E." A monitor arrives only if Pinnacle uses an uncertified product or a court finds another violation, and then the United States picks the monitor and Pinnacle may not oppose it.

Certification is what keeps the monitor away. If Pinnacle licenses a product from anyone other than RealPage or a RealPage reseller, it must obtain and submit to the United States a vendor certification that the product complies with Paragraph IV.A, and must give 30 calendar days written notice before licensing or using it.

The compliance machinery is dated from entry, not publication: an antitrust compliance policy within 30 days, approved by the United States in its sole discretion; a chief antitrust compliance officer, also subject to government approval, replaced within 45 days of a vacancy; annual training; and an annual audit covering revenue-management staff plus at least 8 randomly selected local, regional or supervisory property employees. From 180 days after entry, Pinnacle's General Counsel and everyone who works on or oversees revenue management must attest to compliance under penalty of perjury.

The ban reaches past the software

Section V.A extends the data-sharing prohibition well beyond any algorithm, naming call arounds or market surveys, in-person meetings, calls, text messages, emails, spreadsheets, shared documents, industry meetings and online fora.

Pinnacle is also shut out of RealPage's user community. Under Paragraph V.D it will not attend any RealPage Meetings, defined to take in steering committees, subcommittees, user groups and the RealPage Idea Exchange, and if it does attend it must report the meeting within 30 days, naming every participant and producing every document, chat and recording.

Data already held must be found and taken out of pricing. Within 180 days of entry Pinnacle must identify to the United States in writing the existence and location of any structured data set containing external nonpublic data in its possession. It must also hand over documents describing how its proprietary pricing processes work and, the Competitive Impact Statement says, "must also allow the United States to inspect Pinnacle's software code." Cooperation against the remaining defendants is quantified at up to 15 employees for up to 60 hours of voluntary interviews, conditioned on Pinnacle settling with all the state co-plaintiffs.

What the notice does not say

Publication starts a 60-day public comment period under the Antitrust Procedures and Penalties Act, and the court may enter the judgment only after finding that entry is in the public interest. Comments are due within 60 days of Federal Register publication, or of the first newspaper publication of the statement's summary, whichever is later. The Federal Register's structured field for a comment close date is blank here, so 17 November 2026 is a date computed from that rule, not one the agency published.

There is no effective date in the ordinary regulatory sense. Every operative deadline runs from entry of the Stipulation and Order by the court, which has not happened, so the 180-day switch-off, the 30-day policy deadline and the term are all floating. Under Paragraph XIII the judgment expires five years from entry unless the court extends it, and after three years the United States may end it by notice.

There is no cost figure of any kind. A Tunney Act notice carries no regulatory impact analysis, no paperwork burden estimate and no compliance-cost number, and none appears here. The only allocations stated are that Pinnacle pays for the chief antitrust compliance officer and, if one is appointed, for the monitor.

The notice never says how many apartments Pinnacle manages. The scale figures in the case are RealPage-wide allegations from the amended complaint, which Pinnacle has not admitted: confidential information from over 16 million units, approximately 3 million units at properties using AIRM and YieldStar, and data from over 50,000 monthly phone calls covering over 11 million units.

Neither Pinnacle nor Cushman and Wakefield has a statement in the notice or the department's release. The preamble records consent without testimony, trial or adjudication of any issue of fact or law, and without the judgment constituting evidence against or an admission by any party. There is no fine and no payment in the document, and entry neither impairs nor assists any private antitrust damage action.

It is the sixth settlement in the case.

"This administration will not tolerate illegal actions by corporate landlords that inflate housing prices for Americans," Associate Attorney General Stanley E. Woodward Jr. said in the department's release of 4 September 2026.
