Event Summary

Rosen Law Firm is investigating potential securities claims against Zillow, Inc. and is preparing a class action lawsuit on behalf of its shareholders. This investigation stems from allegations that Zillow may have issued materially misleading business information to the investing public. The core of the issue traces back to September 30, 2025, when the United States — Federal Trade Commission sued Zillow and Redfin over an unlawful agreement to suppress rental advertising competition. This announcement led to a 4.6% drop in Zillow's Class C stock on October 1, 2025. Rosen Law Firm encourages affected investors to join the prospective class action to seek compensation for their losses.
