Z vs ZG: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
Z (Zillow Group) and ZG (Zillow Group) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
Z vs ZG: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | Z | ZG | What it tells you |
|---|---|---|---|
| Forward P/E | 11.33 | 11.38 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 136.24 | 138.76 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.95 | 1.95 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 7% of range | 9% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.77 | 1.80 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how Z and ZG affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. Z and ZG share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined Z and ZG exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.
What does Zillow Group (Z) do?
Zillow Group, Inc. operates the largest online real estate marketplace in the United States, drawing hundreds of millions of monthly visits across the Zillow, Trulia, and StreetEasy brands. Its business has three pillars. Residential (its For Sale core) connects home shoppers with agents, earning mostly through Premier Agent and Showcase. Rentals monetizes multifamily and single-family listings through advertising and lead generation. Mortgages, run through Zillow Home Loans, originates purchase loans and ties financing into search. Zillow is a marketplace and software company, not a homebuilder or iBuyer, so its revenue tracks how actively people transact rather than the value of homes it owns.
What does Zillow Group (ZG) do?
Zillow Group operates the largest and most engaged US residential real-estate audience, spanning Zillow, Trulia, StreetEasy, HotPads, and Out East, plus software and services like Zillow Home Loans, ShowingTime+, Spruce, and Follow Up Boss. Historically its biggest revenue engine has been Premier Agent, where real-estate agents pay for buyer and seller leads, but management is deliberately widening the model into a "housing super app" that lets a mover choose an agent, decide how to sell their current home, get a mortgage, and book a tour in one integrated flow. Rentals and Zillow Home Loans are the fastest-growing pieces, with rentals growth around 42% and on a trajectory to exceed $1 billion in annual revenue, and enhanced markets now driving a large share of connections and double-digit mortgage adoption.
Z vs ZG: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- Z drivers: Housing super app and enhanced markets; Rentals as a growth engine.
- ZG drivers: Housing super app and integration; Rentals and mortgage growth engines.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is housing cyclicality: with existing-home sales near multi-decade lows on elevated mortgage rates, Zillow's Residential and Mortgages revenue depend on a depressed transaction market, and a further slowdown or rate shock could stall growth. For ZG, the biggest risk is competition: CoStar Group is spending aggressively to grow Homes.com and Apartments.com and directly challenge Zillow's audience and rentals lead, which could raise marketing costs and pressure share.
Z or ZG: which should you pick?
Z vs ZG: the full fundamentals
Z. These characterizations are qualitative and tied to the asOf date; verify live figures before acting. Zillow is best understood as a growth marketplace stock, so investors tend to weigh revenue growth, segment mix (Rentals and Mortgages versus Residential), and EBITDA margins more than a headline P/E, which can be distorted while the company transitions from GAAP losses to profits. Because there is no dividend, the entire return case rests on growth and eventual free cash flow rather than income.
ZG. These figures are qualitative and tied to the asOf date; verify live revenue, margins, and per-share numbers with Zillow's latest filings before acting. Because Zillow is valued on growth and future margins rather than steady trailing earnings, its multiple reflects expectations for the housing recovery and super-app adoption, both of which can change quickly. Remember that ZG and Z represent the same company, so any valuation applies to both.
Headline figures (approximate, Jul 2026): Z shows revenue trend Growing at a strong double-digit pace year over year in early 2026, led by Rentals and Mortgages with a steady Residential base, profitability Reached full-year GAAP profitability, a milestone after years of accounting losses; still reinvesting heavily in Rentals and Mortgages, margins Adjusted EBITDA margin has been expanding into the mid-20s percent range as the model scales; watch the trajectory, not a single quarter, dividend None; Zillow pays no dividend and returns capital mainly through share repurchases, so total return depends on price appreciation; ZG shows business model Marketplace and software: Premier Agent leads, Zillow Home Loans, Rentals, plus Trulia and StreetEasy, revenue trend Growing, led by Rentals (~42% growth) and mortgages; long-term aspiration is roughly $5 billion in a normalized market, profitability Reached the milestone of expecting positive GAAP net income in 2025 after prior losses; high gross margins typical of a marketplace, rentals scale On a trajectory to exceed $1 billion in annual revenue.
The bottom line: Z vs ZG
Z and ZG are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined Z and ZG exposure against your real portfolio. It is not an investment adviser.

FAQ
What is the difference between Z and ZG?
+
Zillow Group, Inc. Zillow Group operates the largest and most engaged US residential real-estate audience, spanning Zillow, Trulia, StreetEasy, HotPads, and Out East, plus software and services like Zillow Home Loans, ShowingTime+, Spruce, and Follow Up Boss. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is Z or ZG the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, Z or ZG?
+
On forward P/E (as of August 2026), Z trades at 11.33x and ZG at 11.38x, so Z is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both Z and ZG?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of Z vs ZG?
+
Z: The dominant risk is housing cyclicality: with existing-home sales near multi-decade lows on elevated mortgage rates, Zillow's Residential and Mortgages revenue depend on a depressed transaction market, and a further slowdown or rate shock could stall growth. Industry structure is a second risk: the NAR commission-lawsuit settlement changed how buyer-agent compensation is disclosed and negotiated, and further rule changes around listings and commissions could reshape how portals like Zillow make money. Competition is intensifying, most notably from CoStar's well-funded Homes.com push, plus News Corp's Realtor.com and Redfin (now owned by Rocket Companies), pressuring traffic and ad pricing. Zillow also faces regulatory and legal scrutiny, including antitrust attention to some listings arrangements. Finally, its full-year GAAP profitability is newer and less proven than at mature peers after a long history of losses and heavy reinvestment. ZG: The biggest risk is competition: CoStar Group is spending aggressively to grow Homes.com and Apartments.com and directly challenge Zillow's audience and rentals lead, which could raise marketing costs and pressure share. Housing cyclicality is a second major risk, since high mortgage rates and low transaction volumes suppress the agent, mortgage, and listings revenue that depend on people actually moving. Regulatory and industry shifts, including changes to buyer-agent commissions and real-estate listing rules, could reshape how leads and agents are monetized. Execution risk on the super-app strategy is real, because integrating agents, mortgages, and rentals into one seamless flow is complex and unproven at full scale. Finally, as a growth-oriented internet stock, ZG can be volatile and sensitive to shifts in sentiment, rates, and quarterly connection and revenue trends.
