Compass has sued Zillow, accusing it of using anticompetitive tactics by banning private home listings if sellers market their properties off Zillow’s platform for more than one day.

Compass claims this “Zillow Ban” protects Zillow’s monopoly by forcing listings onto its site and limiting homeowner choice.

The lawsuit seeks to stop Zillow from enforcing this policy and demands damages.

Zillow denies the allegations, saying it aims to create a fair market, ABC News has reported.

The lawsuit comes amid a cooling U.S. housing market, with home sales slowing due to high mortgage rates and rising prices.
