Incident 376: RealPage Algorithm Allegedly Inflates Rents and Reduces Competition in Housing Market

Description: RealPage’s YieldStar pricing algorithm is at the center of allegations that it enabled landlords to coordinate rent increases by sharing nonpublic pricing and occupancy data, raising rents artificially and reducing competition. On January 7, 2025, the U.S. Department of Justice filed an antitrust lawsuit against six major landlords, alleging that they used the algorithm and other direct communication methods to stifle competition, harming renters nationwide.

Variants

A "variant" is an incident that shares the same causative factors, produces similar harms, and involves the same intelligent systems as a known AI incident. Rather than index variants as entirely separate incidents, we list variations of incidents under the first similar incident submitted to the database. Unlike other submission types to the incident database, variants are not required to have reporting in evidence external to the Incident Database. Learn more from the research paper.
