The Justice Department announced a settlement with RealPage Inc. on Nov. 25, 2025, barring landlords from using rent-pricing software that coordinates pricing using competitors' confidential data. The software allowed landlords to see what other properties charged while using algorithms to recommend rent increases. Federal prosecutors argued this constituted illegal price-fixing and collusion through software.

RealPage's software was used across major rental markets to optimize pricing. Landlords input their properties' data into the system. The software aggregated data from competing properties and recommended rents based on what competitors charged. This enabled coordination that would be illegal if done through direct communication between landlords.

Housing advocates documented rent increases in markets where RealPage software was widely adopted. The settlement addresses antitrust concerns about algorithmic collusion. The case sets precedent for prosecuting price coordination through software rather than explicit agreements. RealPage and participating landlords agreed to stop using the coordinated pricing system.
