What happened
The FTC and five states settled antitrust claims against Zillow and Redfin on August 24, the day the case was set to go to trial. Arizona, Connecticut, New York, Virginia and Washington joined the federal complaint, which alleged the two companies broke the Sherman Act and the Clayton Act.
The case grew out of a February 2025 deal in which Zillow paid Redfin $100 million. In return, Redfin agreed to shut down its rental advertising business, move its customers to Zillow and stay out of the market for up to nine years. Regulators argued the arrangement harmed renters and property managers by consolidating two of the three largest online apartment listing services and driving up ad prices.
Under the settlement, Redfin can keep displaying Zillow ads on its sites, but it must resume its own rental advertising business within six months. The companies will also pay the five states $2 million in costs and fees. The FTC approved the stipulated order by a 2-0 vote and filed it in federal court in the Eastern District of Virginia, where it becomes binding once a judge signs it.
The case had cleared a motion to dismiss in May and a summary judgment challenge in July, leaving the companies facing a trial that was scheduled to start on the day of the settlement.
Why this is a GRC story
Competition law is part of the compliance map, and this case is a clean lesson in how an ordinary commercial deal becomes an antitrust problem. The structure that drew the enforcement action was simple: pay a rival to stop competing. Regulators and courts treat market exit arrangements between competitors with suspicion, especially in concentrated markets.
For compliance teams, the takeaway is that antitrust review belongs in the standard checklist for commercial agreements, not just in the merger process. Terms that restrict a competitor's ability to compete, even when they look like reasonable business deals, are the kind of thing you want counsel to see before signature, not after a complaint lands.
What to watch
Watch for the judge's approval of the stipulated order and for how Redfin actually re-enters the rental advertising market over the next six months. Real competition restored is the regulator's stated goal, and the FTC and the states called the settlement a win.
The real estate sector has been under growing antitrust scrutiny, and this settlement may not be the last enforcement action in the space. For companies in any market, the durable question is whether your own agreements contain terms that a regulator could frame as market allocation. If you cannot explain a restrictive clause in plain language, get it reviewed.
