Compass Is Bigger Than Zillow

On June 18th, Compass's market capitalization overtook Zillow's for the first time: $7.47 billion vs. $7.43 billion.

Why it matters: It's a reflection of the shifting power dynamics between brokerages and portals – partially driven by exclusive inventory – in a changing industry.

• A company's market capitalization is a corollary for how the public markets view a company’s current position and future prospects: power and potential.

Last month I posted an analysis comparing the market caps of Zillow and Compass; at the time, Zillow was about $2 billion bigger than Compass.

• And since then, Compass's market cap has continued to rise while Zillow's has continued to slide.

This is the culmination of an inventory strategy Compass has relentlessly executed on since 2024 (but was apparent much earlier, in 2019).

• To quote myself in early 2025, "Exclusive content has the potential to materially shift existing power dynamics across the industry..."

• I've tracked this closely over the past two years – from original research to attending courtroom hearings – dive deeper with my Exclusive Inventory playlist of research.

The bottom line: The shift in market cap is the result of more than just exclusive inventory: AI, Google, legal, and the macro environment are also contributors.

• This is a pretty big shift; imagine telling someone five or ten years ago that a U.S. brokerage would be bigger than the largest real estate portal?

• Things may change again tomorrow, but it doesn't change what happened for the first time last week; the balance of power is shifting.
