The litigation, spearheaded by the law firm Faruqi & Faruqi, LLP, alleges that Zillow executives violated federal securities laws by issuing misleading statements regarding a business agreement with Redfin. According to the complaint, the company characterized the deal as a partnership while allegedly failing to disclose that it functioned as an acquisition. This omission purportedly exposed the company to significant, undisclosed antitrust risks and regulatory scrutiny.

The lawsuit claims that Zillow continued to downplay its legal exposure even after an antitrust action was initiated. Investors interested in serving as lead plaintiff—the party responsible for overseeing the litigation on behalf of the class—must file a motion with the court by the August 10 cutoff. Those who choose not to serve as lead plaintiff remain eligible to participate in any potential recovery, provided they held the stock during the specified class period. Partner Josh Wilson is currently managing inquiries from shareholders and potential whistleblowers regarding the firm's investigation.
