Zillow Group, Inc. Class C is the dominant digital real estate platform in the United States, commanding a massive audience that searches for "Zillow" more often than the term "real estate." The company generated $2.24 billion in revenue in 2024, representing 15% growth as it successfully pivoted from a simple search portal to a "housing super app" that handles mortgages, rentals, and closing services. Despite a challenging housing market with high interest rates, Zillow is currently outperforming the broader industry by capturing more revenue per transaction through its integrated service bundle.
The investment thesis on Zillow is that its unmatched consumer traffic—averaging 204 million monthly unique users—provides a low-cost customer acquisition engine that rivals like CoStar cannot easily replicate. Zillow is transforming from an ad-based lead generator for agents into a transactional platform where it earns fees across the entire home-buying journey. If it can successfully cross-sell mortgages and rentals to its existing search audience, profit margins should expand significantly as fixed technology costs are spread over a larger revenue base.
We believe Zillow is a high-quality business whose stock has been unfairly punished by a temporary freeze in the housing market, creating a rare opportunity to own the industry's clear winner at a steep discount. The company is finally proving it can grow through a downturn by making each user more valuable.
What does it do?
Zillow Group, Inc. Class C is a growth business that earns money by charging real estate professionals for leads and providing transaction services like mortgages and rentals. The company operates a marketplace where home buyers, sellers, and renters search for properties. Its primary revenue engine, Premier Agent, sells advertising and lead-generation tools to real estate agents who want to connect with Zillow's massive audience. Beyond advertising, Zillow increasingly earns direct fees from mortgage originations through Zillow Home Loans and listing fees from multifamily rental properties.
Where does revenue come from?
Most of Zillow's revenue still comes from its residential segment, but the company is rapidly diversifying into mortgages and rentals. The residential segment (Premier Agent) accounts for approximately 70% of revenue. The rentals segment is the second largest, growing 25% year-over-year to $116 million in the latest quarter. Mortgages is the smallest but fastest-growing piece, surging 86% to $41 million as the company integrates lending directly into the home-search app.
Revenue Breakdown
Who are its customers?
Zillow serves a massive base of 204 million average monthly unique users and thousands of real estate agent partners. The company recorded 2.4 billion total visits in the most recent quarter, maintaining its position as the most visited real estate site in the country. Approximately 21% of these users are now using Zillow's bundled "super app" services, such as Zillow Home Loans or integrated title services. On the professional side, Zillow earns from residential agents and multifamily property managers who pay to list and promote their properties to Zillow's high-intent audience.
What gives it staying power?
Zillow's staying power comes from its dominant brand and "top-of-funnel" traffic lead that creates a powerful network effect. People search for "Zillow" more than "real estate," making it the default starting point for any home search. This organic traffic allows Zillow to acquire customers for almost nothing, a structural advantage that competitors must spend billions in marketing to challenge.
Where is it headed?
Zillow is betting its future on becoming a "housing super app" that manages the entire transaction from search to closing. Management is moving away from being a simple billboard for agents toward a model where they participate in the actual transaction. This includes scaling Zillow Showcase listings and expanding the integration of Zillow Home Loans into every home-buying workflow.
Revenue & Earnings Trend: Revenue is accelerating despite a stagnant housing market, with a 17% increase to $554 million in the latest quarter. This growth was driven by 86% gains in the mortgage segment and 25% in rentals, proving Zillow can grow even when home sales are at 30-year lows.
Cash Generation: Free cash flow remains healthy at $230 million for the full year, significantly outperforming GAAP net income. Zillow operates an asset-light model with high gross margins of 73%, allowing most incremental revenue to flow directly toward offsetting its heavy investments in software development and marketing.
Balance Sheet: Zillow maintains a exceptionally strong balance sheet with $2.8 billion in cash and investments and very little debt. This cash pile provides a massive buffer to continue investing in the "super app" strategy and allows for opportunistic share buybacks while competitors are forced to be more cautious.
Zillow Group, Inc. Class C is a financially resilient business with high margins and a massive cash cushion that is successfully decoupling its growth from the broader housing cycle.
The mortgage and rental segments are exploding, with mortgage revenue up 86% and rentals up 25% year-over-year. These segments are successfully cross-selling to Zillow's existing search audience, turning the app into a transactional platform rather than just a search portal.
The "Premier Agent" segment is growing at a more modest 11% and remains sensitive to the total number of home transactions. If the housing market stays frozen for several more years, the slower growth in this core advertising business could offset the gains in newer, faster-growing segments.
The U.S. digital real estate market is roughly $20 billion today and is on track to exceed $35 billion by 2028 as more of the $100 billion in annual commissions moves online. This is a fundamentally attractive industry because home buying is the largest financial transaction in most people's lives, creating huge value for whoever controls the starting point of the search. Zillow stands as the clear market leader, capturing roughly three times the daily active users of its nearest competitor, which gives it a massive runway to monetize transactions rather than just ads.
The competitive dynamic in real estate portals is shifting from a quiet duopoly to an all-out marketing war. While the industry was traditionally rationally structured, CoStar's entry into the residential market has triggered a massive spike in advertising spending across the sector. CoStar’s $1 billion marketing blitz for Homes.com represents the first credible threat to Zillow's traffic dominance in over a decade.
CoStar is using its massive profits from commercial real estate to fund a multi-year attack on Zillow’s search lead. Realtor.com remains a steady but slow-moving competitor, while Redfin’s brokerage-first model struggles with the high costs of employing its own agents. CoStar is the most dangerous threat because it is willing to spend more on marketing than Zillow’s entire annual profit to win the #1 spot.
Zillow is currently holding its ground and gaining share of total transaction value despite the competition. In 2024, Zillow outperformed the broader real estate market by 1,500 basis points, proving its brand remains the primary destination for serious home buyers.
Zillow’s primary source of protection is its massive brand recognition, which functions as a low-cost customer acquisition engine. The fact that "Zillow" is searched more often than "real estate" means the company gets most of its users for free, while competitors must pay Google or TV networks to find them. This organic traffic is the ultimate moat in a digital marketplace.
The company's 73% gross margins and its ability to grow revenue while the overall housing market shrinks prove that its advantage is structural. While Zillow lacks high switching costs—users can easily browse other sites—its massive data advantage and integrated services create a "stickier" experience that competitors cannot easily replicate.
Zillow’s moat is currently narrow but stable. The single most important signal is monthly unique users: as long as Zillow remains the #1 destination by a wide margin, its pricing power with agents and its ability to cross-sell mortgages will remain intact.

Founder-led board with Rich Barton and Lloyd Frink holding significant voting power.
Capital Allocation Track Record
Jeremy Wacksman, who was recently promoted from COO to CEO, has been the primary architect of Zillow's successful pivot away from the risky home-flipping business. Under his leadership, the company has demonstrated remarkable strategic judgment by shutting down its iBuying unit before the housing market crashed, preserving billions in capital. Management has since focused on "high-margin, asset-light" growth, delivering double-digit revenue gains and margin expansion in one of the worst real estate environments in decades.
The primary governance risk is the high degree of control held by co-founders Rich Barton and Lloyd Frink through a multi-class share structure. While this concentration of power can be a concern, both founders have a proven multi-decade track record of building massive travel and real estate platforms. The company has a deep bench of talent, and Wacksman's internal promotion ensures continuity of the "super app" strategy that has already begun to show significant results.
We expect revenue to grow from $3.0B in FY2026 to $5.1B in FY2031 (~11% CAGR), with EPS growing from $2.28 to $7.31 (~26% CAGR). Zillow is capturing a larger share of the real estate transaction by integrating mortgage, rental, and title services into its dominant search platform. Fixed technology and marketing costs are spread over a growing volume of transactions, allowing a higher percentage of each dollar to become profit. Operating margin expected to reach ~28% by FY2031.
Super App bundle adoption reaches 35% of user base. If Zillow hits its 2025 target for bundled services, it will triple the revenue it earns from every transaction.
Mortgage revenue becomes a billion-dollar annual business. Scaling Zillow Home Loans turns a low-margin lead-gen business into a high-value financial services provider.
Rentals segment dominates the multifamily listing market. Capturing the rental market provides a steady, non-cyclical revenue stream that balances for-sale housing volatility.
CoStar's marketing blitz successfully erodes Zillow's search traffic lead. If Homes.com becomes the new starting point for buyers, Zillow's low-cost customer acquisition moat disappears.
Sustained high interest rates freeze the housing market indefinitely. A multi-year low in transaction volume would eventually starve the core Premier Agent advertising business.
Regulatory changes force a collapse in real estate agent commissions. If buyer-agent commissions are eliminated, Zillow's primary customers (agents) will have significantly less money to spend on ads.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach based on next fiscal year (FY+1) earnings to value the business. It fits Zillow because the company has finally reached a GAAP profitability inflection point, making earnings a cleaner signal of value than the revenue multiples used when the business was losing money.
The FY2027 EPS estimate of $3.00 multiplied by a 28x multiple gives a per-share fair value of $84. A 28x multiple sits between high-growth real estate tech like CoStar at 42x and mature digital marketplaces like Booking at 22x, a premium justified by Zillow's dominant audience share and emerging transaction fees. Our input uses the deterministic engine's FY2027 EPS estimate of $3.00, which accounts for the shift toward high-margin software services and rentals growth.
A 5-year Discounted Cash Flow cross-check produces a fair value of $136, suggesting our $84 target is actually quite conservative. While the DCF fully captures the compounding value of the Super App through FY2031, we choose to trust the $84 P/E-based target for our headline fair value because ongoing legal uncertainty typically prevents the market from paying for long-term cash flows. The two methods agree on significant upside, but the P/E approach remains more grounded in current market conditions.
We are assuming rentals revenue continues to grow at a 30% rate through FY2027. This is supported by the most recent Q1 results showing 42% growth and management's guidance for at least 30% growth for the full year 2026, driven by aggressive multifamily listing expansion.
We assume mortgage purchase volume scales to $2.5B annually by FY2027. Given that Q1 2026 saw a 96% increase to $1.5B, this trajectory reflects a reasonable deceleration as the integrated financing product matures across Zillow's existing 186 million monthly unique users.
We assume the Premier Agent advertising business remains the primary cash flow driver despite rule changes. While commission structures are shifting, Zillow's massive traffic lead means agentic AIs and professionals must still rely on the platform for buyer intent data, protecting the company's pricing power.
The biggest risk is an adverse ruling in the ongoing FTC antitrust lawsuit that permanently dismantles the current buyer-agent advertising model. This would force a total re-rating of the core business, likely compressing the forward multiple from 28x to 12x and knocking roughly $48 off the per-share fair value. Investors should watch the "Allowance for legal contingencies" in the next two quarterly reports for signs of a pending settlement or escalating trial costs.
Bear case ($52): Rentals revenue growth falls below 15% for two consecutive quarters as competition from CoStar intensifies; or An FTC ruling or settlement forces a structural change to the Premier Agent model that permanently reduces the take-rate from agent commissions.
Bull case ($120): Mortgage purchase volume exceeds $2.5 billion in FY2026, proving the attach-rate for the super app is working; or Operating margins expand toward 15% by FY2027 as legal expenses drop and fixed-cost leverage takes hold.
