The FTC Just Cleared Its First Big Hurdle Against Zillow and Redfin — And Renters Should Be Paying Attention

By Frances Flynn Thorsen

The Short Version: The Government's Case Just Got a Lot More Real

On May 7, 2026, a federal judge in Alexandria, Virginia, handed the Federal Trade Commission a significant victory — and handed Zillow and Redfin a significant problem. U.S. District Judge Anthony Trenga denied the companies' motion to dismiss the FTC's antitrust lawsuit, ruling that the government had plausibly alleged that the two real estate listing giants violated federal antitrust law.

This is not a final ruling on the merits. The case is not over. But here's why this matters: a motion to dismiss is the defendants' first and easiest line of defense. If you can't get a case thrown out at this stage — when the judge is required to accept all of the government's factual allegations as true — you are in for a real fight. Zillow and Redfin just lost that fight.

For anyone who uses Zillow or Redfin to search for a rental apartment, this case is worth understanding. And for anyone who thinks the real estate industry's legal reckoning ended with the NAR commission settlements, this ruling is a reminder that the government is just getting started.

How Did We Get Here? The $100 Million Deal That Started It All

Let's back up to February 2025. Zillow and Redfin — two of the largest internet listing services (ILSs) in the country — announced what they called a "partnership." Under the deal, Zillow agreed to pay Redfin $100 million upfront, plus a monthly fee, over nine years. In exchange, Redfin agreed to:

• End all of its advertising contracts with managers of multifamily rental properties (buildings with 25 or more units) and help Zillow take over that business;

• Stop competing in the multifamily rental advertising market for up to nine years; and

• Become an exclusive syndicator of Zillow's listings — meaning Redfin's rental search pages would essentially become a copy of Zillow's.

Shortly after the deal was announced, Redfin fired hundreds of employees who had worked on its rental advertising business. Then, according to the FTC's complaint, Zillow hired its pick of those terminated workers.

The FTC filed suit on September 30, 2025, calling the deal an "end run around competition." Five state attorneys general joined the lawsuit shortly after. The government's theory is straightforward: Zillow paid Redfin to stop competing. That, the FTC argues, is a textbook antitrust violation — the kind of "pay-to-exit" arrangement that federal law was designed to prevent.

Three Legal Theories, One Big Problem for Zillow

The FTC's complaint is what antitrust lawyers call a "belt-and-suspenders" filing — it pleads three separate legal theories, any one of which could be enough to win:

1. Section 1 of the Sherman Act: The agreement is an illegal contract or conspiracy in restraint of trade — essentially, a horizontal agreement between competitors to divide the market.

2. Section 7 of the Clayton Act: The deal constitutes an unlawful acquisition because Zillow effectively acquired Redfin's rental advertising business and its competitive position in the market.

3. Section 5 of the FTC Act: Even if the deal doesn't fit neatly into the Sherman or Clayton Act boxes, it constitutes an "unfair method of competition" that the FTC has independent authority to challenge.

Judge Trenga's ruling found that the FTC plausibly alleged violations of antitrust law — which means at least some of these theories survived the motion to dismiss. The case now moves to discovery and, eventually, trial.

What Zillow and Redfin Argued — and Why the Judge Wasn't Convinced

Zillow and Redfin didn't sit quietly. In their motion to dismiss, filed in January 2026, they made several sophisticated arguments:

The "two-sided market" argument. The companies argued that the FTC defined the relevant market too narrowly by focusing only on advertisers (property managers) and ignoring the renter side of the platform. Under Supreme Court precedent for two-sided platforms, they argued, you have to look at the market "as a whole" — and when you do, the deal actually benefits renters by giving them access to more listings on Redfin's platform.

The "flawed market definition" argument. Zillow and Redfin argued that the FTC's definition of a "nationwide" market for ILS advertising was improper because demand for rental advertising is inherently local — a property manager in Pittsburgh isn't competing with one in Phoenix.

The "pro-competitive" argument. The companies argued that the partnership had "plausible net procompetitive effects" — it let Redfin invest money it had been spending on an underperforming rental business into improving its home-search platform, and it let Zillow compete more effectively for property managers' advertising dollars.

Judge Trenga rejected these arguments at the pleading stage. The court found that the FTC had adequately alleged that the agreement would harm competition — and that was enough to let the case proceed. The companies will have another opportunity to make these arguments at summary judgment and at trial, but they'll need to do more than argue; they'll need evidence.

What the Companies Are Saying Now

Both companies issued statements after the ruling, projecting confidence.

Zillow said: "We remain confident we will demonstrate the pro-competitive and consumer benefits of our partnership with Redfin in court."

Redfin (now owned by Rocket Companies, which acquired Redfin in a $1.75 billion deal in 2024) said it was "confident it would be vindicated in court" and that its partnership with Zillow "enabled us to invest more in rental-search innovations on Redfin.com, directly benefiting apartment seekers."

These are standard post-ruling statements, and they don't tell us much about the strength of the underlying case. What we do know is that both companies have already produced hundreds of thousands of documents in discovery — Zillow alone had turned over approximately 240,000 custodial documents and 1,100 noncustodial documents as of February 2026. The paper trail is extensive, and the FTC will have a lot to work with.

Why This Case Is Different From the Commission Lawsuits

If you've been following the NAR commission lawsuits — the Sitzer/Burnett verdict, the Moehrl settlement, the Tuccori opt-in wave — you might be wondering how this case fits into the bigger picture. The answer is: it's related, but it's a different fight.

The commission lawsuits were primarily private class actions brought by home sellers and buyers, challenging the NAR's rules on how buyer-broker commissions were structured and disclosed. Those cases were about the residential sales market and the way agents were paid.

The FTC v. Zillow case is about the rental market and the way listing platforms compete for advertising dollars from property managers. It's a government enforcement action, not a private class action. The FTC is not seeking money damages — it's seeking to unwind the deal entirely and potentially require a divestiture of assets to restore competition.

But there's a common thread: both sets of cases are about whether the real estate industry's dominant players have used their market power to suppress competition in ways that ultimately hurt consumers — whether those consumers are home sellers paying inflated commissions or renters paying higher rents because property managers face less competition for advertising.

What Happens Next

With the motion to dismiss denied, the case proceeds on the following track:

• Discovery: Both sides will continue exchanging documents and taking depositions. Given the volume of documents already produced, this phase is well underway.

• Final Pretrial Conference: Scheduled for May 14, 2026 — just one week after the MTD ruling. This suggests the court is moving the case forward on an aggressive timeline.

• Summary Judgment: Either side can ask the court to rule in its favor without a trial if there are no genuine disputes of material fact. Expect Zillow and Redfin to file a motion for summary judgment once discovery closes.

• Trial: If the case survives summary judgment, it goes to trial before Judge Trenga. Given the complexity of the antitrust issues and the volume of discovery, a trial is likely at least 12 to 18 months away.

The Bottom Line for Renters and Property Managers

If you're a renter who uses Zillow or Redfin to search for an apartment, you may already be experiencing the effects of this deal — fewer choices, less competition between platforms, and potentially higher rents as property managers face a less competitive advertising market. The FTC's lawsuit is an attempt to reverse those effects.

If you're a property manager who used to advertise on Redfin's platform and found yourself pushed toward Zillow after the February 2025 deal, you are exactly the kind of market participant the FTC says was harmed by this agreement.

The case is a long way from over. But the fact that it survived the motion to dismiss — the first and most basic test of whether a lawsuit has legal merit — is a significant signal that the FTC's theory of the case is sound. Judge Trenga has seen the complaint, heard the arguments, and concluded that the government plausibly alleged antitrust violations. That's not nothing.
