Zillow Investors Face August 10 Deadline in Securities Fraud Lawsuit

The lawsuit, captioned Breidert v. Zillow Group, Inc., et al., alleges that Zillow and its senior executives violated federal securities laws by misleading shareholders regarding a deal with Redfin. While Zillow initially characterized the arrangement as a strategic partnership to manage rental listings, the complaint claims the company actually paid Redfin $100 million to exit the multifamily rental advertising market and cease competition.

Financial fallout from the controversy began in September 2025, when the Federal Trade Commission filed an antitrust complaint against both companies. The stock suffered further volatility on February 10, 2026, when Zillow officials disclosed that rising legal expenses would negatively impact EBITDA margins. That announcement triggered a 16.54% decline in Class C shares and a 17.13% drop in Class A shares. The firm Bleichmar Fonti & Auld LLP is representing the class, pursuing claims under the Securities Exchange Act of 1934.
