Compass, the world’s largest residential brokerage, dismissed its antitrust lawsuit against Zillow on March 18, 2026, ending a nine-month legal battle that shook the real estate industry. The move came just one day after Zillow rewrote its listing rules and launched a new product called Zillow Preview. What does this mean for home sellers, agents and the future of how homes are bought and sold in America?
Why Compass Sued Zillow in the First Place
For the past few years, Compass has encouraged agents to use “coming soon” listings as part of its three-phase marketing strategy.1 This approach lets sellers test the waters with private or limited marketing before going fully public on major search sites.
Zillow announced its Listing Access Standards in April 2025, saying the policy was designed to “create an even playing field” as the private listings trend gained momentum. Compass, which built its marketing strategy around private listings and seller choice, sued Zillow in June, alleging that Zillow held “monopoly power” and was violating antitrust laws.2
Compass sued Zillow over a new rule requiring that any home marketed to the public must appear on Zillow within one day of its listing, or it would not be allowed on the platform.1 Compass referred to the rule as the “Zillow ban” and claimed it was anticompetitive.1
The stakes were enormous. In its annual report last month, Zillow said it had about 173 million homes in its database and averaged 235 million unique visitors per month in 2025.3 Being blocked from that audience would be a serious blow to any brokerage.

The Court Ruled Against Compass
In early February, Judge Jeannette Vargas, who was overseeing the lawsuit, denied Compass’s motion for a preliminary injunction, stating that the brokerage did not show a likelihood of success on the merits.4
Compass said at the time that it planned to move forward with the lawsuit, declaring the judge’s ruling was “not a loss.”2
But behind the scenes, the game was already changing.
Compass Found a New Ally in Redfin
Compass International Holdings struck a three-year partnership with Rocket Companies to display coming-soon listings on Redfin.5 Compass “Coming Soon” listings, which previously appeared only on its own brokerages’ website, began appearing on Redfin immediately, with “Private Exclusive” listings to follow.6
This partnership was a game changer. Here is what it brought to the table:
- Compass’s unique inventory now appears on Redfin.com, with the potential to bring more than 500,000 additional home listings to market.7
- Listings displayed on Redfin will not include days on market or price drop history, two metrics Compass CEO Robert Reffkin has called “killers of value.”6
- Compass agents receive buyer leads through Redfin, and Rocket Mortgage offers preferred pricing to Compass clients.8
While Compass had sued Zillow and implicated Redfin in the alleged conspiracy, relations between the companies warmed. A Compass spokesperson told Real Estate News, “Obviously it’s interesting because Redfin was a co-conspirator in our lawsuit with Zillow, but now we’re partnered together.”8
How Zillow Changed Its Rules
On March 17, 2026, Zillow announced Zillow Preview, a new product that brings pre-market home listings into the open by making them publicly visible on Zillow and Trulia.9
It launches in April with initial partners including Keller Williams, REMAX, HomeServices of America, Side and United Real Estate.9
Key details about Zillow Preview:
| Feature | Details |
|---|---|
| Where listings appear | Zillow, Trulia and partner brokerage sites |
| What buyers can do | Discover, save, share listings and connect with listing agents |
| Agent benefit | Listing agents get leads and 10% of the buyer commission residual from Zillow if a Preview connection leads to a closed deal10 |
| Launch timeline | April 2026 |
The original standards required listings to be added to the MLS within one business day. The updated standards no longer include any timelines. Agents can even skip the MLS altogether, as long as the listing is “broadly accessible to the general public.”11
That is a massive shift. What started as a hard-line policy threatening to sideline listings that were not uploaded within 24 hours has softened into something far more strategic, allowing pre-market exposure on Zillow before a property ever hits the MLS.12
Zillow amended its listing rules one day before Compass dropped its case. It will no longer ban listings advertised on a “public-facing website, mobile app, or internet real estate portal,” meaning Compass’s listings on Redfin are now permissible.1
Both Sides Claim Victory
Compass dismissed its lawsuit without prejudice, which means the company could file the case again at a later date.2
Compass CEO Robert Reffkin called the changes a win. “Because of this reversal, we are dismissing our lawsuit against Zillow,” he wrote on social media.2 The company called the end of the “Zillow Ban” a major victory for home sellers and their real estate professionals, saying it ensures homeowners have the freedom to decide when, where and how to market their homes.13
Zillow pushed back on that framing. “As we said from the outset, the claims lacked merit, and the court’s preliminary injunction ruling reinforced that view. Our standards remain in effect,” a Zillow spokesperson said.14
“To the extent Compass continues to limit transparency and harm consumers by hiding listings in a private network, it is at odds with Zillow’s standards. The distinction is simple: Zillow believes in broad, public exposure; the Compass private exclusive listing network is hiding them.”2
What This Means for Home Buyers and Sellers
The dust is settling, but the fight over how homes get marketed online is far from over.
For sellers, the immediate takeaway is more options. Sellers can now pre-market their homes on platforms like Redfin or through Zillow Preview before they ever appear on the MLS. They can control what information gets shown and when.
For buyers, early access to more listings is a clear positive. Buyers will be able to view pre-market homes, save them and request tours. Sellers will see their home get a boost in search results.10
For agents, the rules are loosening. But with loosening rules come new questions about lead generation, branding and commission structures.
While the Compass-Zillow lawsuit may be over, the implications that sparked it are still very much in play. Portals are moving upstream, brokerages are tightening their grip on inventory, and MLSs are being forced to redefine their role.12
This case was never just about two companies fighting in a New York courtroom. It was about who controls the front door to the American housing market. Millions of families start their home search online, and the rules governing what they see, who they talk to and how homes get promoted affect real lives. With both Compass and Zillow now offering pre-market pathways, the winners should be the buyers and sellers who just want a fair shot at finding or selling a home.
