Zillow at Goldman Sachs Communacopia + Technology Conference: growth broadens

Zillow reaffirmed expectations for mid-teens 2026 revenue growth despite forecasting a flat to slightly weaker housing market, with annual U.S. home sales remaining near 4 million versus a historical 6 million. Management maintained its mid-cycle targets of $5 billion in revenue and a 45% EBITDA margin, supported by 13% for-sale revenue growth, expected 30% rentals growth in 2026, and a 10x increase in mortgage volume since 2022. AI Mode has reached 20% of logged-in users and is generating higher engagement, while Zillow Preferred is expected to outgrow its legacy ad model by 35% in 2026. Shares fell 2.94% to $31.20 and remain down 62.5% over the past year, reflecting continued housing-market and execution concerns despite the constructive outlook.

Analysis

The key underwriting question is not top-line growth but whether Zillow can convert its consumer funnel into transaction economics without sacrificing lead volume or agent quality. The migration to success-based monetization defers recognition and makes quarterly comparisons noisier, while embedding Zillow more deeply in agent workflows; if conversion and attach rates hold, the resulting revenue should be less cyclical than legacy advertising and command a higher multiple. Conversely, a renewed rate shock creates a double hit: fewer purchase transactions and longer mortgage revenue-recognition cycles, exposing the gap between claimed share gains and realized contribution profit.

Rentals is the nearer-term earnings lever because it is less tied to existing-home turnover and offers scalable, high-gross-margin advertising inventory. The more consequential competitive effect is on CoStar (CSGP): Zillow's inventory aggregation and expanded distribution can pressure Apartments.com's pricing power with multifamily advertisers, though CSGP's owner data and enterprise workflow moat limits immediate displacement. Redfin (RDFN) is strategically weakened by becoming incremental distribution rather than a standalone rental monetization competitor, but regulatory scrutiny around bundled marketplace reach remains a persistent valuation overhang for Z.

AI engagement is not yet monetization evidence. The upside case requires measurable improvement in lead-to-tour, tour-to-close, mortgage attach, or agent retention; absent these metrics, AI risks becoming an incremental compute and product-investment cost rather than a margin catalyst. At $31, Z is pricing substantial skepticism, but the mid-cycle margin framework implicitly requires both a normalization in housing activity and disciplined incentive spending; the asymmetric catalyst over 1-3 months is proof that transaction mix can grow despite flat unit volumes, not another broad AI product update.

Contrarian view: management's framing understates cyclicality by emphasizing revenue growth through a depressed market. Share gains in a constrained transaction environment can be expensive if they depend on preferred-agent economics, and a weak housing market is not neutral for a business whose highest-value monetization event is a closing. The more attractive setup is to own Z only against a housing-sensitive peer or sector hedge, isolating execution upside from rate-driven transaction risk.

Key Decisions for Investors

• Initiate a small 3-6 month long Z / short RDFN pair after confirming the next quarterly report shows stable or improving for-sale monetization despite revenue classification shifts. Target 20-30% relative upside if Zillow demonstrates durable transaction conversion; exit if Preferred-agent growth slows materially or mortgage contribution profitability deteriorates.
• Use Z as an event-driven long only on a pullback below the recent trading floor, with a 6-12 month horizon, contingent on disclosure of improving mortgage attach rate and rentals growth holding near management's trajectory. Do not underwrite AI engagement alone; a break below the prior low accompanied by reduced full-year growth guidance invalidates the thesis.
• Monitor CSGP for multifamily advertiser pricing, net new customer, and sales-and-marketing trends over the next two earnings cycles. A deceleration in Apartments.com monetization alongside Zillow rental outperformance would support a tactical short CSGP or long Z/short CSGP relative-value trade; without evidence of advertiser substitution, remain on watch.
• Hedge any outright Z exposure with partial short exposure to ITB or XHB through the next major inflation and mortgage-rate catalysts. Zillow's share gains can offset modest unit weakness, but a sustained rise in financing costs would likely overwhelm company-specific execution in the near term.
