In a legal showdown that could shake the foundations of the online real estate market, Compass filed a lawsuit Monday against Zillow, accusing the home search titan of abusing its market dominance by banning private listings and coercing competition into submission.
Filed in the Southern District of New York, the suit alleges that Zillow’s updated policy — which will begin penalizing non-compliant listings by June 30 — aims to corner the market by punishing sellers who don’t immediately post their homes on Zillow. Compass claims this isn’t a policy shift — it’s an antitrust grenade.
Private Listings: The Battle Over “Fresh Bread” vs. “Stale Crumbs”
According to the lawsuit, Zillow’s new rules block any property from appearing on its platform if it hasn’t been shared publicly within a day. After three such violations, listings will be barred altogether. Compass contends that this essentially cripples the ability of sellers to test marketing strategies, maintain privacy, or gauge interest in a controlled environment.
Compass likened Zillow’s fear of private listings to a fear of becoming a marketplace of “stale bread” — homes that have lingered too long without serious buyer engagement. Without first-access to the most in-demand homes, Zillow’s platform loses value for agents who buy leads and for users looking for the latest listings.
“No company should have the power to ban agents or listings simply because they don’t follow that company’s business model,” said Compass CEO Robert Reffkin. “That’s not competition. It’s coercion.”
