Zillow Group investors who lost money in the stock have until August 10, 2026 to ask a court to put them in charge of a securities class action. Rosen Law Firm, which first filed the case, issued a reminder of that deadline on July 25.
The class covers anyone who bought Class A or Class C common stock (NASDAQ: ZG, Z) between February 11, 2025 and May 7, 2026, both dates included. A lead plaintiff acts for the other class members and directs the litigation.
What the suit alleges
The complaint centers on Zillow’s agreement with Redfin Corporation. According to the lawsuit, the defendants told the market it was a partnership when it was in fact an acquisition of Redfin’s business. That, the suit says, exposed Zillow to a much higher risk of regulatory scrutiny and liability under federal antitrust law.
It also claims that after an antitrust lawsuit was filed, Zillow kept playing down its legal exposure. The result, in the plaintiffs’ account, was that statements about the company’s business, operations and prospects were materially false or misleading, or had no reasonable basis. Investors suffered damages, the suit says, when the true details reached the market. None of this has been decided.
What investors can do
No class has been certified. Until one is, no investor is represented by counsel unless they hire a lawyer. They can pick their own, or do nothing and stay an absent class member. The firm says a person’s ability to share in any future recovery does not depend on serving as lead plaintiff.
Rosen says it works on a contingency fee arrangement, so participants pay no out-of-pocket fees or costs. Investors can reach attorney Phillip Kim at 866-767-3653.
