A major technology innovator finds itself on the defensive this week after a start-up company filed an antitrust lawsuit for alleged deceptive business practices. A tech-based online broker named Rex alleged that the National Association of Realtors ("NAR") and Multiple Listing Services ("MLS") operate as a cartel to control access to real estate markets, and that Zillow joined their efforts and cut Rex out of the market.

Zillow, the top real estate listings website, recently changed their online listing policy to segregate listings by real-estate broker type. Rex, founded in 2015, uses data and artificial intelligence rather than traditional brokers to match sellers to home buyers. Rex alleges that Zillow has relegated all listings that are not maintained by brokers who belong to the National Association of Realtors ("NAR") to a "hidden tab" on their website. This change, Rex claims, unfairly lowers the visibility of its listings.
