3. Zillow Group, Inc. (NASDAQ:Z)

YTD Decline in Share Price: 36%

Glenview Capital’s Stake: $79 million 

Zillow Group, Inc. (NASDAQ:Z) is a relatively recent addition to the 13F portfolio of Glenview Capital. The fund first disclosed a stake in the company in the third quarter of 2025. This position comprised just under 890,000 shares. Filings for the fourth quarter of 2025 show that the fund owned 1.1 million shares in the company, up over 30% compared to filings for the previous quarter. Zillow operates a real estate application and website that connects consumers with technology, agents and loan officers, and digital solutions in the United States. The firm offers advertising and marketing solutions for real estate agents as well.

In the latest earnings report, released earlier this month, Zillow Group, Inc. (NASDAQ:Z) admitted that incremental legal expenses created a 160-basis-point headwind on adjusted EBITDA margins. While Zillow is finding ways to squeeze more revenue out of existing segments like Rentals and Mortgages, it is losing the core audience, critics claim. In Q1 2026, traffic to Zillow’s mobile apps and websites declined 3% year-over-year to 220 million average monthly unique users. Total visits also dropped 3% to 2.3 billion. Investors view this as a sign that the Zillow habit is breaking among consumers, making it increasingly difficult for the company to maintain lead over rivals like CoStar.
