Zillow makes most of its money by selling advertising and leads to real estate agents, with smaller but growing revenue streams from rentals and mortgage services. In the fourth quarter of 2025, the company reported $654 million in total revenue, with residential services (primarily agent advertising) accounting for $418 million of that figure.
Selling Leads to Real Estate Agents
The Premier Agent program is Zillow’s biggest moneymaker by a wide margin. When you browse a home listing on Zillow and click to connect with an agent, that agent has paid for the privilege of appearing there. Zillow essentially acts as a middleman between home shoppers and the agents who want to reach them.
Agents pay in one of two ways. The primary model is called “share of voice,” which works like an auction organized by zip code. An agent prepays a monthly amount for a specific zip code, and the share of leads they receive is proportional to how much they spend relative to every other agent buying ads in that same area. If you spend $1,000 a month in a zip code where total agent spending is $10,000, you get roughly 10% of the consumer connections. As more agents pile into a popular zip code, each dollar buys fewer leads. As agents leave, the remaining buyers get more for their money.
The second model, called Flex, flips the payment timing. Agents receive leads at no upfront cost and only pay Zillow a performance fee when a lead actually results in a closed real estate transaction, generally within two years. Flex is available to select partners in certain markets and runs alongside the traditional prepaid model. For agents, Flex reduces the risk of paying for leads that go nowhere. For Zillow, it means larger per-transaction payouts when deals do close.
Residential revenue, which is almost entirely driven by the Premier Agent program, brought in $418 million in Q4 2025 alone, representing about 64% of Zillow’s total revenue that quarter.
Rental Marketplace
Zillow’s rental business has become its second-largest revenue source, generating $168 million in Q4 2025. The model here is straightforward: property management companies and landlords pay to list and promote their rental properties across Zillow’s network of sites.
When you see a multifamily apartment listing on Zillow, the landlord or property manager has typically paid to place it there. They can also pay extra to promote a listing so it appears more prominently and reaches more renters. In some markets, Zillow uses a Pay-Per-Lease model instead, where the company only collects a fee when a renter actually signs a lease with a participating rental partner. This success-based approach mirrors the Flex model on the sales side, tying Zillow’s revenue to actual outcomes rather than impressions or clicks.
Mortgage Origination
Zillow Home Loans is the company’s mortgage lending arm, and it contributed $57 million in Q4 2025 revenue. When someone shopping on Zillow decides to get pre-approved or apply for a mortgage through the platform, Zillow acts as the lender. The company earns money through origination fees and by selling the loans it underwrites on the secondary market, which is the standard way most mortgage lenders operate.
Mortgage revenue is the smallest of Zillow’s three segments, but the company sees it as a natural extension of its core business. A buyer who finds a home on Zillow and gets their financing through Zillow Home Loans keeps the entire transaction within the platform.
Software Tools for the Industry
Zillow also generates revenue by selling software subscriptions to real estate professionals, though the company doesn’t break this out as a separate segment. Its acquisition of ShowingTime in 2021 brought in a widely used scheduling platform that simplifies appointment booking for home showings. At the time of acquisition, ShowingTime had more than 1.2 million active listings subscribed to its services and was used across 370 multiple listing services representing over one million real estate professionals.
ShowingTime’s MarketStats division sells interactive analytics tools and market reports to MLSs, brokerages, and associations. Zillow has also acquired Follow Up Boss, a customer relationship management tool for agents. These software products create subscription revenue from the same professionals who buy advertising through Premier Agent, deepening Zillow’s ties to the industry.
Why Zillow Is Free for Consumers
If you’ve ever wondered why you can browse listings, check Zestimates, and research neighborhoods without paying a dime, the answer is that you’re the product being packaged and sold. Zillow’s entire business model depends on attracting the largest possible audience of home buyers, sellers, and renters, then monetizing that audience by connecting them with agents, landlords, and lenders who pay for access. The more people who use Zillow to search for homes, the more valuable each zip code’s advertising inventory becomes, and the more Zillow can charge the professionals competing for those eyeballs.
This is fundamentally an advertising and lead-generation business built on top of a free consumer platform, which puts Zillow closer to Google’s business model than to a traditional real estate brokerage.
