Compass and Zillow Take Private-Listing Feud to New York Courtroom

Compass, the largest residential brokerage, sued Zillow in June claiming the real estate site acts anticompetitively by banning listings that were publicly marketed elsewhere first. A four-day hearing began Tuesday before a federal judge who will decide whether to temporarily block Zillow’s policy while the lawsuit proceeds. Compass has built a private listings network allowing sellers to quietly market homes with its own agents before posting on public multiple listing services (MLS).
