CoStar's Legal Move Blocked in Real Estate Battle

CoStar, parent of Homes.com, tried to throw its weight behind Compass and MRED in a high-stakes antitrust battle with Zillow—but the judge shut the door on their “friend of the court” brief. Zillow accuses MRED and Compass of forcing it to display listings that violate its own rules, while MRED cut off Zillow’s MLS feed for non-compliance. CoStar argued Zillow’s own “Preview” feature gives it an unfair edge by hiding listings from rivals, painting Zillow as hypocritical. But the court denied the brief without explanation, leaving CoStar’s arguments out of the official record. This legal chess match underscores the brutal, cutthroat competition among real estate tech giants vying for market dominance—and courtroom drama is just one of their weapons.
