REX Real Estate’s antitrust claims continue against NAR and Zillow

REX Real Estate, which provides a residential real estate marketplace outside of the MLS system, sued NAR and Zillow in March 2021, alleging that Zillow’s application of a NAR rule that prevents the commingling of MLS listings and non-MLS listings disproportionately impacts REX listings and thus is anticompetitive. A judge recently dismissed a request from NAR and Zillow to dismiss the case. This lawsuit marks another ongoing suit that could change the way MLSs operate, in this instance, how their participants display IDX listings on their websites.
