Zillow Investors Face August Deadline in Securities Fraud Class Action

The litigation, captioned Breidert v. Zillow Group, Inc., et al., centers on a $100 million deal between Zillow and Redfin. While Zillow publicly framed the arrangement as a strategic partnership for multifamily rental listings, the complaint alleges the payment was actually intended to eliminate Redfin as a competitor in the online rental marketplace. The Federal Trade Commission challenged this agreement in September 2025, sparking the initial decline in Zillow’s Class C and A common stock.

Financial pressure intensified on February 10, 2026, when Zillow’s CFO disclosed that rising legal expenses would create a 200-basis-point headwind to EBITDA margins. That revelation caused a single-day sell-off, with shares dropping over 16% for Class C stock and more than 17% for Class A. The case remains active in the U.S. District Court for the Western District of Washington following a federal judge's recent refusal to dismiss the FTC's underlying antitrust claims.
