The Thesis
Zillow Group is a digital real estate platform that earns money by connecting home buyers, sellers, and renters with agents and financial services. The company generated $2.24 billion in revenue last year, representing 15% growth as it navigated a challenging housing market. The pivot to a "Housing Super App" strategy is the structural shift that moves Zillow from a simple search site to an integrated transaction platform.
If you own ZG, you're betting on three specific things at once.
In our view, there is meaningful upside still ahead, driven by how well Zillow converts its massive traffic into actual home sales and mortgages. The case breaks if mortgage growth stays flat despite rising app traffic, or if new competitors like CoStar successfully siphon off the agent base. For long-term investors, Zillow is the cleanest way to bet on the digitization of the American home-buying process.
Numbers at a Glance
What does it do?
Zillow Group is a maturing business that earns money by selling advertising, software, and financial services to the real estate industry. The company operates the most visited real estate websites in the United States, where it captures user intent at the very start of a home search. It then monetizes this traffic by selling leads to real estate agents through its Premier Agent program, charging for rental listings, and providing mortgage loans directly to consumers. Zillow's goal is to handle the entire transaction: from the first click on a house to the final signature on a mortgage.
Where does revenue come from?
The majority of Zillow’s revenue comes from its Residential segment, which primarily consists of fees paid by real estate agents. This segment includes the Premier Agent program, where agents pay for leads and improved visibility on the platform. Other major revenue lines include Rentals, where landlords pay for listing exposure, and Mortgages, which generates income through loan originations and software.
Revenue Breakdown
Who are its customers?
Zillow Group serves over 200 million monthly unique users and thousands of real estate professionals and landlords across North America. The company attracts a massive consumer base of home shoppers who visit its apps for property data and valuation tools like the Zestimate. On the business side, its customers are real estate agents who rely on Zillow for client leads, as well as property managers who use the platform to fill apartment vacancies. Zillow also serves home buyers directly through its mortgage arm, which processed enough volume to generate $117 million in annual segment revenue in 2023.
What gives it staying power?
Zillow’s staying power comes from its dominant brand and massive traffic which creates a powerful network effect. Most home searches in the U.S. start on Zillow, making it an essential utility for agents who must be where the buyers are. This top-of-funnel dominance is incredibly difficult and expensive for competitors to replicate.
Where is it headed?
Zillow is betting its future on the Housing Super App, an integrated experience that handles every step of the move. Management is moving away from just selling leads to agents and toward capturing a larger share of the transaction through in-house mortgages, title services, and seller solutions. If successful, this shift will significantly increase the revenue Zillow earns from every home sold on its platform.
Revenue has begun to accelerate as Zillow successfully cross-sells more services to its massive user base. While the total 2024 revenue reached $2.24 billion, the most recent quarter showed a jump to $0.71 billion, suggesting that the "Super App" strategy is gaining traction even in a high-rate environment.
Cash generation remains a key strength with free cash flow of $0.28 billion consistently tracking above GAAP net income. This gap reveals a high-quality earnings profile where the core digital marketplace requires very little physical capital to grow.
The balance sheet is exceptionally strong with only 0.10x debt-to-equity and a large net cash position. This financial cushion allows the company to invest aggressively in new products and weather prolonged periods of low housing turnover without needing to raise outside capital.
Zillow Group is a financially resilient platform with high-margin software economics and a fortress balance sheet.
The Rentals and Mortgages segments are diversifying the business away from the volatile home-purchase market. These lines grew significantly last year, providing a secondary growth engine that doesn't rely solely on agents buying leads for existing homes.
Competition from CoStar's Homes.com is the biggest risk to Zillow's lead-generation margins. If CoStar’s massive advertising spend forces Zillow to increase its own marketing costs, the high gross margins of 73% could come under pressure.
The U.S. residential real estate technology market is roughly $30 billion today and is growing at ~8% annually as more of the $100 billion in annual commissions moves to digital platforms. Pricing power in this industry is structural because of the scarcity of high-intent buyer leads. Zillow Group is the clear market leader, acting as the primary gateway for American home searches. Its massive scale gives it a significant runway to capture more of the transaction through services like mortgages and title insurance.
The real estate portal market is shifting from a quiet duopoly into a more aggressive competitive landscape. Barriers to entry are high because of the massive marketing spend required to build a household brand. The industry is consolidating as larger platforms acquire smaller software tools to build "all-in-one" ecosystems for agents.
CoStar is the most dangerous threat because it is using its massive commercial real estate cash flow to fund a multi-billion dollar attack on Zillow’s dominance. Redfin(RDFN) competes by offering lower fees, while Realtor.com remains a persistent challenger for high-quality leads. CoStar’s $1 billion advertising blitz for Homes.com is the single biggest threat to Zillow's traffic lead.
Zillow is currently holding its ground and even gaining share in newer categories like rentals. The fact that Zillow's revenue grew 15% in a year where total U.S. home sales were at multi-decade lows proves its platform is becoming more essential, not less.
Zillow’s primary source of protection is a powerful network effect built on its massive consumer traffic. Because nearly all home shoppers use Zillow, all serious real estate agents must maintain a presence on the platform to find clients. This traffic dominance creates a "virtuous cycle" where better data attracts more users, which in turn attracts more agents and listings.
The company’s 73.3% gross margins and consistent free cash flow are clear evidence of a high-quality digital marketplace. However, the low ROIC of 0.2% suggests that Zillow is still in a heavy investment phase to build out its mortgage and title infrastructure. These numbers prove Zillow has a real brand moat, but it has not yet fully translated that traffic into a highly profitable transaction engine.
The moat is currently stable, but the next two years will be the ultimate test. The forward-looking verdict depends on whether Zillow can maintain its traffic lead without significantly increasing its marketing spend to fight off CoStar.

Capital Allocation Track Record
Jeremy Wacksman is a Zillow veteran who was promoted to CEO in August 2024 to execute the "Housing Super App" strategy. While the company is still recovering from the financial hit of the failed iBuying experiment, the current leadership has returned the business to its high-margin, asset-light roots. Management's success now depends entirely on whether they can turn Zillow's massive traffic into a meaningful mortgage and title business.
