Will the Chicago MLS win over Zillow usher in a new era for private listings?
A federal judge denied Zillow's injunction against the Chicago MLS (MRED) and Compass, allowing private listing networks to operate. The ruling may enable MLSes to expand nationally with private networks, though Zillow argues these networks harm transparency and market access. The case is now in arbitration, with Congress also scrutinizing the practices.
