Real Estate Rumble: Compass Sues Zillow Over “Exclusionary” Listing Policy

Real estate giant Compass has just thrown a major legal punch at Zillow, accusing the popular home search site of unfair, anti-competitive practices. The lawsuit, filed in the U.S. District Court for the Southern District of New York, centers on Zillow’s alleged refusal to list homes that were first marketed elsewhere.

What’s the Core of the Complaint?

Compass claims Zillow has implemented an “exclusionary policy” that essentially creates a “Zillow Ban.” Here’s how it reportedly works:

• If a home seller and their agent initially market a property off Zillow for more than a single day, Zillow (and its alleged “allies” Redfin and eXp Realty) will ban that home from appearing on their platforms.
• Compass argues this policy is a deliberate move to “protect its monopoly” by forcing all listings onto Zillow’s dominant platform. Their goal, according to Compass, is to “monetize each home listing” and maintain market control.

Compass firmly believes this “Zillow Ban” stifles competition and limits options for homeowners. “In a free and competitive market,” Compass stated in the lawsuit, “competitors’ products and strategies should rise and fall on merit—not the whims of a monopolist gatekeeper like Zillow.”

Why Would Listings Start “Off Zillow” Anyway?

This whole situation highlights an interesting dynamic in the real estate world. While listing a home on major platforms like Zillow and the Multiple Listing Services (MLS) offers maximum exposure, it comes with a downside: these platforms display how long a home has been on the market and any price reductions. This information can give potential buyers leverage to negotiate lower prices or other concessions.

To counter this, many brokerages, including Compass, offer sellers alternatives:

• Pocket Listings/Office Exclusives: These listings are initially shared only internally among a brokerage’s own agents, keeping them off the public internet and the MLS.
• Brokerage Website Listings: Compass also allows sellers to make their listing public only on Compass.com. These listings don’t show market time or price reductions, and while agents from other brokerages can find them, they don’t appear on Zillow.

Compass contends that Zillow’s new policy directly targets these strategies. If a home is listed on Compass.com for more than a day, Zillow would reportedly refuse to include it later, even if the seller then opts for broader advertising.

What Does Compass Want?

Compass is seeking:

• An injunction to prevent Zillow from implementing and enforcing this “Zillow Ban” and any similar policies.
• A trial by jury.
• An unspecified amount in damages.

Zillow’s Response and the Bigger Picture

A Zillow spokesperson has publicly stated that the company believes the claims are “unfounded” and that they will “vigorously defend against them.” Zillow asserts its focus remains on “creating a level playing field that serves the best interests of everyone in the home buying and selling journey.”

This legal battle comes amidst a challenging and highly competitive U.S. housing market:

• Slow Sales: Sales of previously owned homes have been sluggish, with April 2025 seeing one of the slowest paces for that month since 2009. May saw only a slight uptick.
• High Costs: Elevated mortgage rates and rising home prices continue to discourage prospective homebuyers.
• Seller’s Market (Sort Of): As of April, Redfin data showed nearly 34% more sellers than active buyers in the market, a stark imbalance not seen since before 2013 (excluding the initial pandemic slowdown in April 2020).

This lawsuit highlights the intense competition among real estate platforms and how strategies to attract both listings and buyers are constantly evolving in a tough market. We’ll be watching closely to see how this legal challenge unfolds!
