ZILLOW vs. COMPASS

The Real Estate Industry's Biggest Battle Is Reshaping How Homes Are Bought and Sold

A Seismic Shift in American Real Estate

The U.S. residential real estate industry is in the middle of a once-in-a-generation upheaval. Two of the most powerful players in the business — Zillow, the dominant home-search portal, and Compass, the nation's largest residential brokerage by sales volume — are locked in an explosive antitrust lawsuit that could permanently alter how homes are marketed across America. At the same time, Compass has completed one of the most shocking mergers in real estate history, absorbing Anywhere Real Estate and its iconic brands including Coldwell Banker, Century 21, Sotheby's International Realty, and more.

For real estate agents, brokers, and industry professionals, the outcome of these battles will determine who controls listings, who profits from buyer traffic, and who gets to define the future of real estate marketing. If you work in this industry — or cover it — this is the story you need to understand inside and out.

KEY TAKEAWAY: The Zillow vs. Compass lawsuit is not just about two companies — it is a battle over who controls the gateway to real estate listings, and therefore who holds the power in the $4+ trillion U.S. housing market.

How Did We Get Here? The Background on the Zillow-Compass War

The Clear Cooperation Policy: The Spark That Lit the Fire

The roots of the Zillow-Compass conflict trace back to the National Association of Realtors (NAR) Clear Cooperation Policy (CCP), a rule requiring brokers to submit a listing to their Multiple Listing Service within one business day of marketing it publicly. The policy was designed to ensure transparency and equal access to listings, but it was polarizing from day one.

In October 2024, NAR's Emerging Issues Advisory Board began re-examining the future of CCP. The debate quickly divided the industry:

- Compass CEO Robert Reffkin argued that sellers should have the right to market their listings however and wherever they choose — including exclusively on Compass's own platform before going to the MLS.
- Zillow strongly backed CCP, arguing that withholding listings from the MLS limits seller reach and harms consumers.
- In March 2025, NAR took a middle path — keeping CCP but adding a Delayed Marketing Exempt Listings option, allowing sellers to delay public MLS marketing. Both Compass and Zillow claimed the decision validated their respective positions.
Compass's 3-Phased Marketing Strategy: The Business Model at Stake

Central to this entire dispute is Compass's proprietary 3-Phased Marketing Strategy, which works like this:

- Phase 1 — Private Exclusives: The listing is first shared internally with Compass agents only, invisible to the public.
- Phase 2 — Coming Soon: The property is publicly displayed on Compass's own website as a "Coming Soon" listing, before being submitted to the MLS.
- Phase 3 — Active MLS Listing: Only after the Compass-exclusive phases are completed does the listing go to the MLS, and then syndicate to portals like Zillow.

Zillow sees this strategy as a direct threat to its business model. Zillow's revenue is driven by buyer traffic — the more listings it has, the more buyers it attracts, the more it can charge agents for lead generation. A Compass strategy that keeps listings off Zillow undermines that engine.

The Antitrust Lawsuit — Compass Takes Zillow to Court

The Filing: June 23, 2025

On June 23, 2025, Compass filed a landmark antitrust complaint against Zillow in federal court. The lawsuit alleges that Zillow employed anticompetitive tactics to protect its monopoly and revenues in violation of antitrust law, specifically targeting what Compass calls the "Zillow Ban."

What Exactly Is the "Zillow Ban"?
The Zillow Ban: If a home seller and their agent publicly market a property anywhere other than Zillow for more than one day — on social media, on a brokerage website, via email blast, or any other public channel — Zillow and its allies will permanently ban that listing from their search platforms, making the home invisible to the majority of buyers.

Compass argues this ban is far-reaching and punishes sellers and agents who simply want to use Compass's marketing approach. Key allegations in the lawsuit include:

- Monopolistic Behavior: Compass claims Zillow holds monopoly power in the online home search market and is abusing that power to stifle competition.
- Conspiracy with Redfin and eXp Realty: Compass alleges Zillow conspired with competitors Redfin (which adopted similar listing standards) and eXp Realty to collectively boycott Compass listings — an alleged violation of the Sherman Antitrust Act.
- Harm to Sellers: The suit argues that by banning off-MLS marketed listings, Zillow removes seller choice and forces homeowners into Zillow's preferred marketing pipeline.
- Harm to Compass's Business: Compass claims the ban damages both its reputation and the competitive value of its 3-Phased Marketing Strategy.
Zillow's Defense

Zillow's response was straightforward and aggressive:

- No Antitrust Standing: Zillow argued Compass failed to demonstrate an antitrust injury.
- Right to Choose Partners: Zillow argued it has every legal right to decide whose listings it displays. As a private platform, it is not required by antitrust law to carry Compass's listings.
- No Conspiracy: Zillow denied any coordinated agreement with Redfin or eXp Realty, stating it made its listing policy decisions unilaterally.
- Declining Market Share Defense: Zillow pointed to growing competition from CoStar's Homes.com, Realtor.com, and Redfin as evidence it does not hold monopoly power.

The Court Ruling — Zillow Wins Round One (February 2026)

In November 2025, the case went to a four-day federal hearing in New York City before U.S. District Judge Jeannette Vargas. Compass sought a preliminary injunction — a temporary halt to the Zillow Ban while the full lawsuit played out.

On February 6, 2026, Judge Vargas denied Compass's motion in a 50-page opinion. The ruling was a significant win for Zillow, at least for now. Here's what the judge found:

Key FindingJudge's ReasoningNo Proven MonopolyCompass failed to show Zillow has monopoly power given growing competition and consumers using multiple search platforms simultaneously.No Proven ConspiracyThe circumstantial evidence Compass presented about a Zillow-Redfin conspiracy was "ambiguous at best" and contradicted by witness testimony.No Irreparable HarmThe court did not need to reach the harm question, since Compass did not prove its case was likely to succeed on the merits.Zillow's Right to Set StandardsZillow is not legally required to display Compass listings, regardless of whether it has market power.
IMPORTANT NOTE: This ruling only decided the preliminary injunction — it did NOT dismiss the full lawsuit. The antitrust case against Zillow continues, and a final verdict could still go either way. The real estate industry is watching closely.

The Mega-Merger — Compass Acquires Anywhere Real Estate

A $10 Billion Deal That Shocked the Industry

While fighting Zillow in the courts, Compass CEO Robert Reffkin executed one of the most audacious strategic moves in real estate history. On September 22, 2025, Compass announced an all-stock merger with Anywhere Real Estate, the parent company of some of the most recognizable brokerage brands on the planet.

What Brands Did Compass Just Acquire?

The Anywhere acquisition did not just add agents. It added legendary, globally recognized brands that have been household names for decades. Here's what Compass now controls:

- Coldwell Banker — One of the oldest and most trusted residential real estate brands in the U.S., with thousands of franchise offices.
- Century 21 — Globally recognized, with a massive footprint in both domestic and international real estate.
- Sotheby's International Realty — The world's premier luxury real estate brand, synonymous with high-end properties in iconic markets.
- Corcoran — A dominant luxury brand in New York City, the Hamptons, Palm Beach, and South Florida.
- ERA Real Estate — A global franchise brand with thousands of offices and agents.
- Better Homes and Gardens Real Estate — A widely recognized lifestyle and real estate brand with a national franchise network.
- Relocation, Title, and Escrow Operations — Anywhere's integrated service lines add significant non-commission revenue streams to the combined company.
What Robert Reffkin Has Said About the Deal

Reffkin has been careful to reassure agents of Anywhere's franchise brands that nothing will change overnight. Key commitments he has made publicly include:

- Franchise brands will maintain their independence and continue to operate as they always have.
- There will be no mandates requiring anyone to opt into Compass's Private Exclusives listing program.
- Sellers will always have the freedom to choose how their listings are marketed.
- Compass will never directly contact franchise affiliates' clients.
- Each agent's data belongs to them.

What the Industry Is Saying — Reactions from Real Estate Leaders

The Compass-Anywhere deal generated some of the most vocal industry commentary in years. Here's a cross-section of what major voices are saying:

"This is a major power play. I give credit to Robert Reffkin for pulling off such an incredible feat in the real estate industry." — Anthony Lamacchia, Boston-based broker/owner
"If anybody doubted we were in an era of industry consolidation, this acquisition by Compass defines the moment." — Jack Miller, CEO, T3 Sixty
"The real story isn't Compass buying Anywhere. It's about building leverage to challenge the existing MLS, NAR and Zillow hegemony." — Mike DelPrete, Real Estate Tech Strategist
"Compass acquiring Anywhere creates a real estate Goliath. It's now arguably the most powerful player in the industry, big enough to challenge Zillow, NAR, and essentially create a viable MLS with their own network." — Glennda Baker, CEO, Glennda Baker & Associates

Zillow's Financial Performance — Under Siege but Still Dominant

Despite facing eight lawsuits and unprecedented competitive pressure, Zillow's financials in 2025 were remarkably strong. The company continued to grow revenue and expand its business model across multiple segments.

Zillow's Eight Lawsuits in 2025

Zillow did not just face the Compass case. The company was hit with a barrage of legal challenges from multiple directions:

- Compass (Antitrust): The headline antitrust lawsuit over the Zillow Ban and alleged conspiracy with Redfin and eXp Realty.
- CoStar Group (Copyright Infringement): CoStar accused Zillow of "rampant" copyright infringement of listing photos, calling it one of the largest real estate image infringement cases in history.
- Federal Trade Commission (FTC): Federal regulators also took aim at Zillow's business practices.
- RESPA Claims: Multiple lawsuits alleged violations of the Real Estate Settlement Procedures Act.
- Consumer Lawsuits: Homebuyers filed suits over various aspects of Zillow's platform and lead generation programs.
- Job Discrimination Claims: Employment-related lawsuits were also filed against the company.

The Bigger Picture — An Industry in Unprecedented Consolidation

2025 was the year real estate stopped looking like an industry and started looking like a chess match. Beyond the Zillow-Compass war, the entire landscape shifted dramatically:

Major Industry Moves in 2025-2026
- Rocket Companies acquires Redfin: Rocket, already the largest U.S. mortgage lender, acquired real estate portal Redfin, creating a potential end-to-end home-buying platform and a genuine threat to Zillow's dominance.
- Rocket Companies acquires Mr. Cooper: Rocket also purchased Mr. Cooper, a major mortgage servicer, further consolidating the mortgage-to-real-estate pipeline.
- Compass acquires @properties Christie's International Real Estate: Completed in December 2024, this deal added a major luxury franchise network to Compass's portfolio and served as the playbook for the Anywhere deal.
- Google enters the portal wars: In December 2025, Google tested a home search feature displaying listings with a "Request a Tour" button directly in search results. One Goldman Sachs analyst called the move a potential "long-term risk for real estate portals like Zillow."
- MLS Consolidation Continues: The concentration of MLSs mirrors the brokerage consolidation trend, reducing the number of independent data sources in the market.
The "Great Consolidation" — Why It's Happening Now

Several forces are driving this consolidation wave simultaneously:

- Compressed Margins: The NAR commission settlement and growing consumer awareness of agent fees are squeezing brokerage profitability, making scale more critical than ever.
- Technology Investment Requirements: Building competitive AI-driven search, mortgage, and CRM tools requires capital that only large companies can deploy.
- Portal Power Dynamics: As Zillow touches approximately 80% of U.S. transactions, brokerages with no platform leverage are increasingly at a disadvantage.
- Exclusive Inventory as Competitive Moat: The ability to control listings before they hit the MLS is emerging as the most valuable asset in real estate — and the primary reason for the Zillow-Compass war.

What This Means for Real Estate Agents and Brokers

If you are a working real estate agent or broker, this is not abstract industry news. The Zillow-Compass war and the mega-mergers reshaping this industry will directly affect your business. Here's how:

For Agents at Coldwell Banker, Century 21, ERA, and Other Anywhere Brands
- Robert Reffkin has publicly promised that franchise brands will maintain full independence.
- Compass's technology platform may become available to franchise agents over time, potentially offering CRM, marketing, and productivity tools currently only available to owned-brokerage Compass agents.
- Watch for: How Compass monetizes Anywhere's relocation, title, and escrow businesses and whether that creates new referral pipelines or conflicts of interest.
- Key Question: Will Compass eventually push Anywhere franchise agents toward its Private Exclusives model? Reffkin says no — but the competitive pressure to leverage that inventory will be enormous.
For Independent and Small Brokerage Agents
- Consolidation at the top puts pressure on mid-size and boutique brokerages competing for the same listings and clients.
- The "Zillow Ban" debate is a preview of a world where portals and brokerages may each demand exclusivity — putting agents in the middle.
- Opportunity: Boutique brokerages can differentiate on personalized service and local expertise in ways that a 340,000-agent global conglomerate cannot replicate.
- Networking Matters More: In a consolidating market, professional relationships and referral networks become your most durable competitive advantage.
For eXp Realty Agents
- eXp is named as a Zillow ally in the Compass lawsuit. eXp adopted listing standards aligned with Zillow's — positioning the cloud-based brokerage firmly in the Zillow ecosystem.
- eXp Realty's CEO backed Zillow's listing standards publicly, which may help eXp agents maintain access to Zillow's massive buyer traffic pool as the legal battle continues.
- Long-term, agents should monitor how the lawsuit's resolution affects listing policy at eXp.
For Agents at Compass and Anywhere Brands
- The combined Compass International Holdings is now positioned as a genuine counterweight to Zillow's platform dominance.
- Access to Private Exclusives and the 3-Phased Marketing Strategy may become a stronger value proposition if Compass wins its antitrust battle or forces a negotiated settlement.
- Risk to Watch: Antitrust regulators may still weigh in on the size and market power of the combined Compass-Anywhere entity.

What to Watch For in 2026 and Beyond

The story is far from over. Here are the most important developments to track throughout 2026:

1. The Compass Antitrust Case — Full Trial

The preliminary injunction loss was a setback, not a defeat. The full antitrust trial will require Compass to prove its monopoly and conspiracy claims with a much higher burden of evidence. If Compass succeeds, the implications for Zillow's listing policies — and the broader portal industry — would be profound.

2. The CoStar Copyright Case

CoStar's lawsuit alleging Zillow's "rampant" copyright infringement of listing photos could become one of the largest real estate image infringement cases in U.S. history. A major verdict here could force Zillow to overhaul how it acquires and displays listing content.
