Zillow’s Private Listings Strategy Comes Into Focus Through Court Filings

Newly released court documents reviewed by Inman have highlighted Zillow’s thinking as the US portal battled the rise of private listing networks among brokerages. The documents form part of the ongoing lawsuit brought by Compass against Zillow in June and shed light on how the portal’s much-debated ban on non-public listings (known internally as 'Listing Access Standards') was shaped.

At the heart of the documents is a blunt internal assessment of Zillow’s dependency on listings. As chief industry development officer, Errol Samuelson put it:

“Listings are the lifeblood of our company. No listings, no eyeballs, no sales.”

The concern was that the growth of private listing networks, most visibly associated with Compass but adopted by others, could weaken Zillow’s inventory and, by extension, its advertising revenues.

The response, according to the filings, combined incentives and penalties. The penalty was Zillow’s policy to block listings that were not shared in a way the portal could access and display within one business day. Internally, executives discussed how forcefully to apply that stance. CEO Jeremy Wacksman suggested lining up brokerage deals before going public, writing, “In my head, we would have lined up a group of deals … and then jointly announced them AND announced our stick plans publicly.”

Alongside the 'stick' approach sat a series of carrots. The documents reference ideas to ingest listings directly from brokerages rather than from MLSs, preferential routing of consumer leads, accelerated access to Zillow's Flex product, and discounted CRM software. An early partnership with brokerage eXp Realty was seen as a catalyst. Samuelson noted that eXp’s leadership believed aligning publicly with Zillow could be used to recruit agents away from firms operating private networks.

The detail is striking not because of the personalities involved, but because of the playbook. Zillow viewed listing access as existential and was prepared to leverage its consumer reach, advertising products, and partnerships to defend it.

Zillow has pushed back strongly on the interpretation of the documents, stating that the exhibits were “cherry-picked” and that its published Listing Access Standards represent its true strategy. The lawsuit remains unresolved and is one of six major suits that Zillow's legal team is fighting.
