A coalition of attorneys general from five states—New York, Virginia, Arizona, Connecticut, and Washington—has filed a lawsuit against Zillow and Redfin, accusing them of colluding to stifle competition in the online housing rental market. The lawsuit follows a recent complaint from the Federal Trade Commission (FTC) and centers on a February agreement where Zillow paid Redfin $100 million to cease its apartment rental advertising business. This arrangement is claimed to violate federal antitrust laws, potentially harming renters by reducing options and increasing costs. The AGs are seeking an injunction to prevent further anti-competitive behavior and may propose restructuring the companies to foster competition. Both Zillow and Redfin have publicly rejected the allegations, asserting that their partnership is beneficial for consumers and enhances access to rental listings.
