Zillow Group is trading 4.1% down now at $31.20 (-4.06%) after a U.S. district court denied its preliminary injunction against Midwest Real Estate Data on September 16, 2026.

  • The ruling increases the risk of losing MRED’s Chicago listing feed, potentially affecting up to 2.5% of nationwide listings and weakening Zillow Group’s competitive position.
  • Broader pressure came from the Fed’s rate hike and elevated Treasury yields; the stock was reported down 2% to $31.96 in afternoon trading.
