This week, a significant number of homes in the Chicago area disappeared from Zillow, causing confusion among homeowners and potential buyers. Approximately 43,000 property listings across Illinois and parts of Indiana, Iowa, and Wisconsin were removed after the Midwest Real Estate Data (MRED) suspended Zillow's access to its listings feed. As a result, Zillow displayed only about 2,000 homes for sale, compared to more than 8,600 on Realtor.com and 4,700 on Homes.com. The conflict arises from a struggle over 'private exclusive' listings promoted by Compass, the largest real estate brokerage in the U.S., which Zillow argues undermines market transparency. Zillow has initiated a lawsuit against MRED and Compass for anti-competitive behavior, claiming that the actions of these organizations limit consumer access to listings. Real estate agents express concern that many buyers are unaware of the reduced number of homes available to them, complicating their search in a market where Zillow remains the most visited real estate platform. The ongoing battle reflects a broader shift in the U.S. housing market regarding how listings are shared and marketed.
