Zillow's CEO on growth during a housing crisis

March 2, 2026

Key Takeaways Copied to clipboard!

  • Zillow's evolution has shifted from being a classic ad marketplace based on public listing data to focusing on building an end-to-end software platform to facilitate the entire real estate transaction, measured by transaction volume rather than just audience size. 
  • Zillow actively enforces a policy requiring listings to appear on its platform within 24 hours to maintain broad transparency and combat selective marketing practices by industry players who might otherwise try to hide inventory. 
  • The current housing affordability crisis is fundamentally an availability problem, stemming from a nearly 5 million home underbuild deficit since the 2008 financial crisis, which is exacerbated by existing homeowners being locked into low mortgage rates. 
  • Zillow's CEO, Jeremy Wacksman, believes real estate is structurally more durable against platform disaggregation (like the 'DoorDash problem' from new AI interfaces) due to its complexity, regulation, and localized, relationship-driven nature. 
  • Zillow's long-term durability strategy centers on vertical integration—owning the software, workflows, and data for transactors (buyers/sellers/agents)—rather than just the top-of-funnel consumer entertainment. 
  • To combat AI-generated 'slop' and maintain data integrity, Zillow relies on the compliance mechanisms of licensed professionals within the MLS structure, while also using AI tools like Showcase to generate more realistic content to incentivize accurate marketing. 

Segments

Zillow’s Founding and Evolution

(00:05:23)
  • Key Takeaway: Zillow was founded 20 years ago to democratize real estate information, initially launching with the Zestimate before pivoting from a pure ads marketplace to a transaction-focused platform.
  • Summary: The company’s founding inspiration was to provide access to real estate data previously locked in professional databases, starting with the Zestimate in 2006. For over a decade, Zillow operated as an advertising marketplace selling leads to professionals. The business later shifted focus to building software to help buyers, renters, and sellers transact, measuring success by the volume of transactions facilitated.
MLS Data Sharing Dynamics

(00:09:04)
  • Key Takeaway: The US real estate listing database (MLS) is unique globally because it is broadly shared among competitors, functioning as a public good that Zillow must compete on top of with superior product experiences.
  • Summary: Unlike private databases in other countries, the US MLS system is cooperative, allowing Zillow and its competitors access to the same listing data. Zillow must differentiate itself through better touring experiences and integrated services, as the underlying listing data is commoditized. Zillow previously sourced listings independently before the current MLS feed structure became widely available.
Decision Making and Company Structure

(00:16:47)
  • Key Takeaway: Zillow operates under a functional business matrix structure, prioritizing product engineering as the largest group, and decision-making is guided by seeking truth through data rather than simply wanting to be right.
  • Summary: The company structure, largely established before Jeremy Wacksman became CEO, uses functional teams (like engineering and design) matrixed into business groups (like for-sale and rentals). The CEO’s decision framework emphasizes data-informed choices to find the truth, often looking to customer feedback from buyers, sellers, and agents. Mature businesses like the for-sale segment are integrated, while others like Rentals operate more independently until maturity.
Policy on Listing Speed

(00:26:28)
  • Key Takeaway: Zillow mandates that listings appear within 24 hours to protect market transparency and prevent companies from selectively hiding inventory while still benefiting from access to other shared listings.
  • Summary: This policy is designed to counter companies that might try to hoard listings privately, which Zillow argues leads to higher consumer costs, mirroring less transparent international markets. The rule incentivizes sellers and agents to broadly market homes quickly, which Zillow believes maximizes seller price and speed. The policy is a direct counter to industry players attempting to create closed ecosystems following recent legal settlements regarding broker fees.
Addressing Buyer Affordability Crisis

(00:35:02)
  • Key Takeaway: The current housing market is suffering from an affordability crisis driven by a nearly 5 million home supply deficit accumulated since 2008, leading to depressed transaction volumes.
  • Summary: While mortgage rates are a factor, the primary issue is the massive gap between home price appreciation (nearly 100% in some markets) and income growth. Zillow estimates the US is nearly 5 million homes underbuilt, requiring both new construction and existing homeowners to become ‘unstuck’ from low legacy mortgages to balance the market. Zillow’s growth comes from gaining share in this depressed market, as their transaction share remains in the single digits.
Value of Data in Local Transactions

(00:44:09)
  • Key Takeaway: In real estate, incremental data is immensely valuable for buyers making trade-offs, and for agents, data that automates busy work allows them to focus on high-value client service and negotiation.
  • Summary: For buyers, more data helps minimize regret when making trade-offs between price, location, and features, exemplified by tools like Zillow Showcase that enhance virtual touring. For agents, software that handles administrative tasks (like CRM follow-ups) frees them to perform essential front-office client work, which is their core value proposition. This focus on efficiency aligns Zillow’s goals with the agent’s need to focus on local, atom-based expertise rather than digital busywork.
Threat of AI Aggregation

(00:54:12)
  • Key Takeaway: New interfaces like voice-activated chatbots threaten Zillow’s aggregator model by potentially removing its mobile app interface from the transaction path.
  • Summary: The ability of new interfaces, potentially voice-activated or chatbot-driven, to directly access public databases poses a threat to aggregators like Zillow by disintermediating the user experience. This ‘DoorDash problem’ is seen as a potential future shift away from the mobile app revolution’s interface structure. Zillow believes its category is different, but acknowledges the risk of losing top-of-funnel engagement.
Real Estate Durability vs. AI

(00:55:12)
  • Key Takeaway: Real estate’s complexity, regulation, and infrequent consumer interaction (once every 14 years) provide structural durability against immediate aggregation changes seen in daily services.
  • Summary: Real estate is uniquely complex, regulated, and localized, making it harder to disrupt than categories like food delivery or ride-sharing. While consumers might use AI for entertainment browsing (checking home prices), Zillow aims to capture them during the actual transaction phase using its software and workflows. Building vertical integration around transactors is considered the most durable component against interface evolution.
Transactors vs. Dreamers Focus

(00:57:39)
  • Key Takeaway: Zillow prioritizes serving transactors (those buying/selling) as the more durable customer segment, viewing browsers/dreamers as efficient sources for future customer acquisition cost (CAC) advantages.
  • Summary: The business model focuses on the transactors, as they are where revenue is generated, but the large base of dreamers provides a significant CAC advantage and lifetime value. A drop in free, direct traffic (currently 80% of Zillow’s traffic) would necessitate a different customer acquisition equation focused on where transactional traffic originates.
Guarding Against AI Slop

(00:59:15)
  • Key Takeaway: Zillow combats misleading AI-generated content and over-processed imagery by leveraging licensed professionals’ endorsements and developing AI tools that promote realistic visualizations.
  • Summary: Platforms with user content face threats from AI ‘slop,’ evidenced by increasingly unrealistic HDR photos and virtual staging in listings. For MLS-sourced content, licensed professionals stamping accuracy provides a policing mechanism, while Zillow builds its own compliance tools for non-MLS rentals. The company uses AI to generate realistic flyovers (Showcase) to incentivize better marketing, countering the incentive to hide flaws.
Proprietary Tech vs. Open Platform

(01:04:47)
  • Key Takeaway: Zillow prioritizes leading with innovation and supporting open standards for rich media to drive overall transaction digitization, even if proprietary tech eventually commoditizes.
  • Summary: The broad philosophy is that any current innovation will quickly become commoditized table stakes, so Zillow focuses on creating incentives for marketplace adoption. The company supports various 3D interactive floor plans, even those not built with Zillow’s tech, because increasing the volume of digitized content benefits their transaction-volume-based business. Bending towards openness helps ensure all content utilizes the necessary tools to move transactions online.
Agency for Ecosystem Participants

(01:06:02)
  • Key Takeaway: Agency for buyers stems from making the constrained decision in a low-supply market, while agent agency is enhanced by providing software that connects Zillow data insights to their entire customer database.
  • Summary: In the current constrained housing market, buyer agency comes from making the final, high-stakes decision among limited options, not from the breadth of initial browsing. For agents, Zillow is expanding agency by launching tools that connect intelligence derived from Zillow customers to the agent’s entire, non-Zillow customer data set. The ultimate goal is to create a fully integrated, digital transaction experience within the app.
