Zillow's CEO on growth during a housing crisis

What It Covers

Zillow CEO Jeremy Waxman explains how the company is evolving from a mobile listings platform into a vertically integrated real estate transaction business, covering the politics of MLS database access, the controversial 24-hour listing policy, mortgage origination, AI-powered virtual tours, and why single-digit transaction share leaves substantial room for growth despite a frozen housing market.

Key Questions Answered

• •Transaction share as growth lever: Zillow captures only single-digit percentage of U.S. real estate transactions despite 70% of home buyers visiting the platform monthly. This gap represents the core growth strategy — increasing share from roughly 5–7% in a 4-million-home annual market matters more than overall market recovery. Even modest share gains in a depressed market drive meaningful revenue growth without needing transaction volume to normalize.
• •Housing supply deficit: The U.S. is approximately 5 million homes underbuilt, a deficit accumulated after construction collapsed post-2008 financial crisis and never recovered to match household formation rates. Mortgage rate lock-in compounds this structural shortage. Waxman argues affordability is primarily a supply problem, not a rates problem — and that rates-focused policy discussions miss the more durable constraint preventing market normalization.
• •MLS database structure as competitive moat: Over 500 regional Multiple Listing Services share listings cooperatively, making the same inventory available to every platform simultaneously. This U.S.-specific structure — unique globally — commoditizes listing data, forcing Zillow to compete on product quality, touring tools, financing integration, and agent software rather than exclusive inventory. Understanding this means platform differentiation must happen above the data layer, not within it.
• •Vertical integration via mortgage origination: Zillow now originates mortgages directly rather than selling leads to lenders, giving it a customer acquisition cost advantage since buyers are already on-platform. The strategic goal is a single app where buyers get preapproved, communicate with agents, submit offers, and close — eliminating fragmented Gmail threads and separate vendor relationships. Zillow currently holds basis points of mortgage market share, leaving substantial runway for growth.
• •Agent software as durable business layer: Zillow's Follow-up Boss CRM and new tools that apply Zillow buyer intelligence to agents' entire client databases — not just Zillow-sourced leads — represent the most defensible revenue stream against AI disaggregation. By automating follow-ups, scheduling, and back-office workflows, Zillow positions agents to focus on negotiation and client relationships, making the software sticky regardless of how consumers initially discover listings.
• •24-hour listing policy as transparency enforcement: Zillow's rule requiring properties to appear on its platform within 24 hours of any marketing activity targets selective listing practices where brokerages show homes only to their own buyer pool before broader market exposure. Waxman frames this as protecting seller outcomes — broad public marketing statistically maximizes sale price and speed. The policy directly conflicts with Compass's private listing strategy and is currently in active litigation.
