A federal judge blocked part of New York's algorithmic rent-setting law, citing First Amendment protections for commercial speech in a ruling affecting RealPage.
A federal court in New York has issued a preliminary ruling that blocks a key part of the state’s 2025 law regulating algorithmic rent-setting, creating a significant legal hurdle for regulators seeking to police automated pricing. In a decision dated September 29, U.S. District Judge Valerie Caproni ruled that New York Attorney General Letitia James cannot enforce a provision prohibiting landlords from using software recommendations to set rental prices, citing First Amendment protections for commercial speech. This ruling introduces a constitutional complication to the broader debate over how governments can regulate pricing algorithms without infringing on protected expression.
What happened in the RealPage lawsuit
The legal battle began in November 2025 when RealPage, a company that licenses rent-recommendation software to property owners, sued the state of New York. The company argued that the state’s law, enacted in October 2025 as an addition to the Donnelly Act antitrust statute, suppressed protected advice by treating the use of software recommendations as an unlawful agreement. New York countered that the statute regulated anticompetitive conduct rather than speech.
Judge Caproni sided with RealPage on a specific provision of the law. Section 3 of the statute treats a landlord’s setting or adjusting lease terms based on recommendations from “coordinating” software as an unlawful agreement. Caproni classified these recommendations as commercial speech, which triggers a legal standard known as intermediate scrutiny. Under this standard, the government must show a reasonable fit between its objectives and its restrictions. While acknowledging New York’s substantial interest in protecting competition, the judge found the provision too broad because it did not distinguish between recommendations based on public information and those relying on competitors’ confidential data.
“Although it is a close call,” Caproni wrote, RealPage was “marginally, likely to succeed on the merits.”
The distinction between speech and anticompetitive conduct
The ruling highlights a critical tension in modern antitrust enforcement: the difference between prohibiting anticompetitive conduct and restricting the communication of pricing data. Judge Caproni left intact Section 2 of the law, which prohibits facilitating actual anticompetitive agreements among competing landlords, including through software. This means that while landlords may now use software recommendations, they cannot use that software to coordinate prices with competitors in a way that violates antitrust laws.
This distinction is crucial for understanding the limits of state power. The court did not rule that algorithmic price-fixing is legal; it only blocked the specific mechanism that treated the mere use of software advice as illegal per se. The injunction is preliminary, meaning the case is still developing, and New York has requested reconsideration, a move RealPage has opposed.
Why this matters for investors and the industry
For investors in the proptech and data analytics sectors, this ruling suggests that state-level attempts to ban specific types of pricing software may face constitutional challenges if they do not carefully target anticompetitive behavior rather than speech. The decision could influence how other states draft similar legislation, potentially leading to more nuanced laws that focus on the use of nonpublic competitor data rather than the existence of the software itself.
The context of this ruling is further shaped by a separate settlement between the U.S. Department of Justice and RealPage, announced in November 2025 and finalized in May 2026. That settlement required RealPage to restrict the use of competitors’ nonpublic information and to name a compliance monitor. Assistant Attorney General Abigail Slater stated at the time, “Competing companies must make independent pricing decisions.” The court noted that RealPage has since shifted toward using customers’ own information and public data, making the constitutional dispute specifically about the reach of New York’s prohibition over advice produced under this changed model.
What happens next
The legal landscape remains fluid. New York Attorney General Letitia James has sought to vacate the injunction, arguing that the state’s interests in consumer protection are paramount. RealPage has urged the court to preserve its ruling. The final outcome will depend on whether the state can provide a stronger explanation of why restricting recommendations based primarily on public data advances its competition objectives.
Experts note that the implications for personalized pricing restrictions beyond housing remain untested. The ruling does not immunize other pricing laws, but it sets a precedent that regulators must connect restrictions on algorithmic advice to demonstrable pricing harms. For businesses, the key takeaway is that protected advice remains distinct from an unlawful agreement to coordinate prices, a distinction that will likely shape future regulatory frameworks in the tech and real estate sectors.
