Rosen Law Firm is investigating a class action lawsuit against Zillow Group following allegations that the company provided misleading business information to investors. This follows an FTC lawsuit accusing Zillow and Redfin of an illegal agreement to suppress rental advertising competition, which caused Zillow's stock to drop 4.6% on October 1, 2025. Investors who purchased Zillow securities may be eligible for compensation through a contingency fee arrangement. The Rosen Law Firm, known for its expertise in securities class actions, is preparing to represent affected shareholders in seeking recovery of losses.
