Is ZG a Buy or a Sell? The Bull and Bear Case (2026)

That depends on which case you find more convincing, and both are on this page. The bull case rests on Housing super app and integration, with revenue trend at Growing, led by Rentals (~42% growth) and mortgages; long-term aspiration is roughly $5 billion in a normalized market. The bear case rests on 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. Analysts covering it are spread from $34.00 to $110.00, which is itself a signal that this is genuinely contested. If you believe the thesis, the real questions become sizing and overlap rather than timing. Walnut is not an investment adviser and this is not a recommendation.

Nobody can answer that for you, and the honest version of the question is narrower: has anything changed in the reason you bought it? The bear case on this page is the place to check. 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. If that risk is what you were worried about and it is now playing out, that is a real signal. If the price simply fell while the thesis held, that is a different situation entirely. The most pessimistic published target is $34.00, -0.6% from the $34.22 price, which is one analyst's downside case rather than a floor. Walnut is not an investment adviser.

Housing super app and integration. Zillow's core strategy is to convert its top-of-funnel audience into a connected transaction platform where movers pick an agent, finance through Zillow Home Loans, and book tours in one flow. The most optimistic analyst target on ZG is $110.00, +221.4% from the $34.22 price. That figure is only reachable if this thesis works close to its best case.

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. The most pessimistic published target is $34.00, -0.6% from the current price, which is roughly what the stock is worth if these risks bite rather than the drivers.

Decide that in advance, because it is far harder to think clearly once a position is moving against you. The concrete tripwires here: the driver behind the bull case (Housing super app and integration) stalling in the reported numbers rather than in the narrative, the risk above (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) turning from a possibility into a reported fact, or the position growing large enough that a bad outcome would matter to your whole portfolio regardless of who is right.

That depends on your goals, time horizon, and risk tolerance, and this is not investment advice. The bull case is Zillow's dominant audience, fast-growing rentals and mortgage businesses, a super-app strategy, and reaching positive GAAP net income. The bear case is a sluggish housing market, aggressive competition from CoStar's Homes.com, and a valuation that leans on future growth. Weigh both against the rest of your portfolio.

ZG and Z are two share classes of the same company, Zillow Group. ZG is the Class A share and carries voting rights, while Z is the Class C share and generally has no vote. They represent the same underlying economics, so their prices track each other closely and differ mainly in voting rights and trading liquidity. Most retail investors can choose either based on price and availability.

Zillow's largest historical revenue source is Premier Agent, where real-estate agents pay for leads from buyers and sellers. It also earns from Zillow Home Loans (mortgage origination), a growing Rentals marketplace where property managers advertise listings, and software and services like ShowingTime+ and Follow Up Boss. The strategy is to combine these into one integrated housing super app.
