As part of their February 2025 deal, Redfin allegedly agreed that its website would be “an exclusive syndicator of Zillow listings,” meaning Redfin would essentially just copy over the listings from Zillow, the FTC said in a statement. Zillow and Redfin are among the largest rental listing websites in the United States by traffic and revenue, the FTC said in the lawsuit. Redfin said that it strongly disagrees with the FTC allegations and that its partnership gave more access to visitors and advertisers. “By the end of 2024, it was clear that the existing number of Redfin advertising customers couldn’t justify the cost of maintaining our rentals sales force,” a Redfin spokesperson said. While Zillow said it was working in the interests of consumer transparency, Compass said Zillow adds costs to the home-buying process.
