The U.S. Federal Trade Commission (FTC) and five states had argued that the Zillow-Redfin partnership, which involved Redfin winding down its rental listing business and referring customers to Zillow in exchange for $100 million plus fees, drove up costs for landlords and decreased listing quality for renters. An expert for the FTC and states estimated Zillow customers paid an average of 14.5% more per listing after Redfin stopped competing. The settlement requires Redfin to rebuild its rental advertising business within six months, though it can maintain its partnership with Zillow through at least 2030.
