Zillow Group -- How the Business Works
Zillow Group is the dominant US real estate search portal, commanding over 50% of all real
estate web traffic -- more than 2x the next competitor. The company is executing a
"Housing Super App" strategy that vertically integrates search, agent matching (Premier Agent),
mortgage origination (Zillow Home Loans), and transaction workflows (Enhanced Markets). Zillow
operates three reporting segments: Residential (~65% of revenue), Rentals (~24%), and Mortgages
(~8%). FY2025 revenue was $2.58B (+16% YoY) with 221M average monthly unique users. The stock
trades at $40.60 (down ~57% from 52-week highs) with a composite score of 6.5/10 -- a HOLD
with contrarian accumulation appeal near 52-week lows.

The traffic moat is the foundation, but verticalization is the growth story:
Zillow commands 50%+ of US real estate web traffic with 80% coming organically -- a brand
advantage that cannot be replicated by spending (CoStar proved this by investing $3B+ into
Homes.com and achieving only single-digit share). The strategic evolution is converting this
massive audience into integrated transactions via Enhanced Markets, where buyers use ZHL
financing and are matched with Premier Agents. Buyers using both ZHL and Premier Agent
transact at an 80% higher rate. Mid-cycle, management targets $5B revenue with 45% EBITDA
margins at 6M existing home sales -- roughly 2x current revenue with dramatic margin expansion.

Rentals and Mortgages are the growth engines, not Residential.
Residential revenue grew 8% YoY in Q4 despite existing home sales stuck at ~4.1M (vs. ~6M
normalized) -- Zillow outperformed the housing market by 1,300 bps in FY2025. Rentals at
+45% Q4 YoY is the standout, with a clear path to $1B+ annual revenue. Mortgages grew 39%
on purchase origination volume up 67% in Q4. FY2025 total revenue of $2.58B (+16% YoY)
demonstrates the platform can grow through a weak housing cycle. At normalized 6M existing
home sales, management targets $5B revenue -- roughly 2x current levels.

Key risks to the business model
Housing Market Cyclicality
Existing home sales stuck at ~4.1M vs. ~6M normalized. Revenue upside is
gated by a macro recovery that has not materialized. Rates remain elevated.
Regulatory / Legal Overhang
RESPA/RICO case around Zillow Home Loans. CoStar $1B copyright lawsuit.
FTC scrutiny. Management says no expected material financial impact.
Mortgage Integration Risk
ZHL still small at less than $200M annual revenue. Mortgage is capital-intensive and
cyclical. Vertical integration may face pushback from agent partners.
Private Listing Networks
Some agents pushing off-MLS listings. Currently less than 1% of listings but could
grow. Zillow has enforced listing access standards to protect portal value.
