Zillow Group Inc. has lost access to residential real estate listings in Chicago and its suburbs after Midwest Real Estate Data LLC (MRED) suspended data sharing for 43,000 properties. This development follows a federal lawsuit filed by Zillow last week against MRED and brokerage firm Compass Inc. over alleged collusion to hide homes from buyers, according to livemint.com.

The suspension came after MRED accused Zillow of excluding certain homes that were previously listed privately. MRED, which manages the multiple listing service for Chicago’s residential real estate market, decided to block Zillow’s access to its data on Wednesday. This action is part of an escalating dispute between Zillow and Compass, with MRED CEO Rebecca Jensen emphasizing that all listings should be displayed as required by regulations.

This conflict highlights tensions in the real estate sector around data transparency and competition. Zillow, a major online real estate platform, relies heavily on access to comprehensive listings to serve buyers and sellers. The lawsuit and data suspension could impact how consumers search for homes in Chicago, potentially limiting Zillow’s market reach and affecting competition in the residential real estate market.

Looking ahead, the legal battle initiated by Zillow will likely determine whether MRED and Compass’s practices violate competition laws. Stakeholders in Chicago’s real estate market will be watching closely for court rulings and any regulatory responses that could influence data sharing policies and market dynamics in the region.
