Zillow grows despite a declining housing market

01 Running thesis

Growth outside agent ads

Zillow's bull case is that the company can grow even when the housing market shrinks. Q2 2026 backed that up. Revenue rose 18% to $772 million, despite management downgrading their view on the purchase mortgage market to a slight decline for the year.

The shift is clear in the mix. Residential, mostly agent advertising, remains the core. But Rentals and Mortgages are growing much faster. Rentals revenue rose 31% in Q2 2026, and Mortgages revenue jumped 75%. Zillow Home Loans achieved positive per-unit economics, validating the strategy to integrate the transaction.

The bear case centers on the messy transition to a preferred partner model. This shift delays revenue recognition by six to twelve months and transfers some revenue from Residential to Mortgages. These changes, plus persistent legal risks and a 7% workforce reduction, create near-term noise.

Finn's view remains mixed. Growth is the strongest part of the story, but recent performance and sentiment are weaker. The stock needs Zillow to prove the preferred model transition will pay off without dragging down profitability.

Aug 2026Q2 2026 results showed 18% revenue growth to $772 million. Mortgages grew 75% and Zillow Home Loans achieved positive per-unit economics.
May 2026Q1 2026 results strengthened the growth case. Revenue rose 18% to $708 million, with Rentals up 42% and Mortgages up 56% year over year.
May 2026Management reaffirmed full-year guidance for mid-teens revenue growth, about 30% Rentals growth, and EBITDA margin expansion, even while assuming a flat housing market.
Feb 2026The 2025 10-K confirmed strong full-year diversification, with Rentals up 39% and Mortgages up 37%. It also made commission rule change risk more concrete.
Feb 2026Legal risk became a clearer near-term profit drag. Management estimated higher legal expenses would create about a 200 basis point EBITDA margin headwind in Q1 2026.
Oct 2025Q3 2025 filings showed the same split story: Rentals and Mortgages kept accelerating, while new complaints from the FTC, state attorneys general, competitors, and consumers raised risk.
Aug 2025Q2 2025 results raised confidence in the diversification plan. Rentals grew 36%, Mortgages grew 41%, and management lifted its full-year 2025 revenue outlook to mid-teens growth.
02 Business model

A housing traffic tollbooth

Zillow brings together people who want to buy, sell, rent, or finance a home. It then sells access, tools, and services to the professionals who want those customers. Those professionals include agents, lenders, landlords, and property managers.

The main money source is Residential. This segment relies on Premier Agent, where agents pay Zillow to reach home shoppers. Zillow is actively shifting from upfront advertising to a success-based preferred model, where partners pay only when they close a deal.

Rentals makes money from property manager ads, landlord tools, and renter application services. Mortgages generates revenue through Zillow Home Loans and lender advertising. Other revenue is mostly display advertising.

The model works best when Zillow has massive consumer traffic and professionals believe that traffic turns into closed transactions. It breaks if agent budgets fall, mortgage growth costs too much, legal limits change how leads are sold, or competitors pull renters and home shoppers away.

05 Risk factors

What could go wrong

Transition noise masks growth

Medium impact · High odds

Zillow is shifting to a preferred partner model. This creates a mechanical shift of revenue out of Residential and delays revenue recognition by six to twelve months.

We watchQuarterly total revenue growth and any commentary on preferred partner model adoption.

Housing market deterioration

Medium impact · High odds

Management revised their macro housing forecast to a low-to-mid single digit decline for 2026. A worsening market could strain agent budgets and slow origination volumes.

We watchU.S. existing home sales trends and Zillow Residential revenue growth.

FTC trial and legal costs

High impact · Medium odds

Management noted legal expenses as a headwind earlier in the year. If the FTC trial drags on or other cases emerge, profit margin expansion could fall short of targets.

We watchEBITDA margin guidance and updates on FTC trial timing or expense.

Agent economics weaken

High impact · Medium odds

Recent industry settlements resulted in rule changes affecting how commissions are offered. If agent commissions fall meaningfully, agents may spend less on Zillow.

06 Quick answers

In one breath

How does Zillow make money?

Zillow makes most of its money by selling ads, leads, and software to real estate agents, landlords, property managers, and lenders. It also originates mortgages through Zillow Home Loans.

Why is Zillow growing if the housing market is slow?

The fast growth is coming from Rentals and Mortgages, not only from traditional agent ads. In Q2 2026, Rentals grew 31% and Mortgages grew 75% year over year.

What is the preferred partner model?

Zillow is shifting from upfront advertising to a success-based model. Preferred partners pay Zillow a portion of their commission when a transaction actually closes.

Is Zillow still mainly an agent advertising company?

Yes, for now. Residential was 60% of Q2 2026 revenue, but Rentals and Mortgages are taking a larger share because they are growing faster.
