Zillow Group just announced that it had reached a resolution with the Federal Trade Commission and the attorneys general of five states over its multifamily rental listings syndication partnership with Redfin. The settlement, structured as a stipulated final order containing no admission of liability, preserves the core of the arrangement that regulators had spent nearly a year attacking. It also imposes conditions that will reshape the competitive landscape in rental advertising in ways that both companies will spend the next several years working through.

The dispute traces back to February 2025, when Zillow agreed to pay Redfin $100 million for the exclusive right to syndicate multifamily rental listings across Redfin’s platforms, including Rent.com and ApartmentGuide.com. The deal effectively took Redfin out of the multifamily internet listing service business and handed its customer relationships to Zillow. In September 2025, the FTC sued both companies, arguing that the arrangement removed an independent competitor from an advertising market that was already concentrated. A day later, attorneys general in Arizona, Connecticut, New York, Virginia, and Washington filed parallel suits, which a judge consolidated in December. The case was headed toward trial this month after courts declined the FTC’s request for expedited judgment.

The settlement gives Zillow most of what it wanted on the syndication question. Listings will continue to flow across Zillow, Trulia, HotPads, Rent.com, ApartmentGuide, and Redfin through at least June 30, 2030. “Our syndication partnership with Redfin has already expanded access to multifamily listings across multiple platforms, bringing more leads and leases to property managers and more options to renters,” said Michael Sherman, General Manager and SVP of Zillow Rentals. The numbers Zillow has published support that framing, at least on distribution. Multifamily properties on Redfin’s websites nearly quadrupled following the partnership, and multifamily properties on Zillow’s own sites grew roughly 40%. Properties previously listed on only one of the two networks saw increased lead volume from reaching audiences they had not been able to access before.

What the settlement also does, and what Zillow’s announcement handles more delicately, is require Redfin to rebuild the business Zillow paid it to exit. The FTC explained that the order “unwinds an agreement under which Zillow paid Redfin $100 million to stop competing and hand off all its customers to Zillow.” Under the order, Redfin must hire a general manager, a sales team, and a fully trained customer support organization for its internet listing service business, launch advertising to promote it, and make a multiyear commitment to operating it. Redfin faces monetary penalties for failing to hit the prescribed timelines, must provide regular compliance updates to the FTC, and both companies must notify the Commission before entering any future syndication agreement containing provisions that restrict either party from competing for ILS customers.

“Now, with the ability to offer more multifamily advertising solutions in addition to the existing partnership, we can do even more to support the marketplace,” said Sherman. Beginning in 2027, both Zillow and Redfin will sell standalone multifamily advertising products alongside the syndication arrangement, which does give housing providers more purchasing flexibility than a single bundled offering would. But it also means Zillow will be competing directly against a Redfin rentals business that regulators have specifically ordered into existence and are actively monitoring for compliance.

The strategic picture that emerges from all of this is one of Zillow pushing aggressively into multifamily, a category where it has historically been less dominant than it is in for-sale residential. Rentals have become one of the company’s fastest-growing revenue segments, and the infrastructure Zillow has assembled, its own platform plus Trulia, HotPads, and now syndicated distribution through Redfin’s properties, gives it a network reach that few competitors can match. “Zillow is building a simpler, more affordable rental marketplace, one where renters can find more homes with less hassle, and housing providers can list once and reach more people,” the company said in its announcement. That single-listing, multi-platform distribution model is a direct challenge to the way multifamily advertising has traditionally been sold.

The competitor most affected is CoStar Group, which owns Apartments.com and its associated network including ApartmentFinder, ForRent, and Apartamentos.com. CoStar has long held the dominant position in multifamily internet listing services, and its rental advertising business generates a substantial share of company revenue. Zillow’s expanding distribution footprint and its stated ambition to make rental advertising more affordable represent a pricing and reach challenge to that position. CoStar has its own regulatory and legal complications at the moment, including antitrust counterclaims from CREXI heading toward trial and a recently filed class action from its own customers, alongside its $800 million acquisition of Zonda. The multifamily listing category is becoming a genuinely contested market for the first time in years.

Sherman explained that Zillow wants to focus on now that the litigation overhang has lifted. “This positive resolution enables us to keep our energy on innovating for renters and property managers, and ultimately making renting easier, more affordable and better for everyone,” he said. That is the language of a company that spent a year defending a deal and would prefer to spend the next several building product. The resolution removes significant regulatory risk from Zillow’s rentals strategy and clarifies the rules under which it can operate. It also guarantees that the competitor it tried to buy out will be back in the market by 2027, funded, staffed, and under regulatory obligation to compete. For property managers and multifamily owners, that combination is likely to produce exactly what regulators intended: more places to advertise and more leverage in negotiating what it costs.
