The Washington lawsuit follows separate investor-law-firm scrutiny and centers on a February 2025 Zillow-Redfin agreement, the FTC’s antitrust case, rising legal costs, and an August 10, 2026 lead plaintiff deadline.
Bleichmar Fonti & Auld LLP said a securities class action has been filed against Zillow Group, Inc. and certain senior executives in the U.S. District Court for the Western District of Washington, with investors seeking lead plaintiff status by August 10, 2026. The case, Breidert v. Zillow Group, Inc., et al., No. 26-cv-02016, alleges claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 tied to Zillow’s February 6, 2025 agreement with Redfin, which plaintiffs say was described as a partnership but actually involved a $100 million payment for Redfin to stop competing and wind down its multifamily rental advertising business. Separately, The Schall Law Firm said it is investigating potential securities law violations on behalf of Zillow investors. Both releases point to the FTC’s antitrust case against Zillow and Redfin, increased legal costs disclosed by Zillow, and related share-price declines.
