The U.S. Federal Trade Commission (FTC) has sued online real estate brokerages Zillow and Redfin, alleging collusion to suppress rental advertising competition. According to the FTC complaint, Zillow and Redfin entered a rental listing partnership worth $100 million in February 2025, whereby Redfin agreed to stop competing with advertisers, end contracts with existing partners and syndicate Zillow listings on its own website. Zillow effectively bought Redfin’s share of the rental advertising market, the commission’s complaint claims. “Redfin strongly disagrees with the FTC’s allegations and is confident we will be vindicated by a court of law,” the company said in a statement provided to Scotsman Guide. We remain confident in this partnership and the enhanced value it has delivered and will continue to deliver to consumers.”
