On September 24, Zillow fell 5.54% in regular trading, trading at $28.98/share, with turnover of approximately $84.04 million. The decline was driven by the fallout from the company's recent loss in a Chicago-area antitrust lawsuit related to its listings information flow, raising market concerns over potential adverse impacts on Zillow's core listing distribution business model.

The antitrust ruling, disclosed in mid-September, centers on Zillow's practices in aggregating and distributing real estate listings in the Chicago market. The adverse verdict has amplified investor unease at a time when the company is already navigating a complex transition to its Preferred partnership model, which has introduced near-term revenue recognition delays and margin compression. Analysts have noted the shift makes Zillow's financials more complex and could prompt investors to treat the stock more like a cyclical brokerage.

Sector-wide headwinds further exacerbated the selloff. Within the Real Estate Services sector, Opendoor fell 6.16%, Compass declined 5.38%, CBRE Group dropped 3.23%, Jones Lang LaSalle lost 2.73%, and CoStar slid 2.35%, reflecting broad-based weakness amid persistently elevated mortgage rates above 6.5% and softening housing transaction volumes.
