Zillow and Redfin Settle FTC Antitrust Case — and Have to Rebuild the Competitor They Killed

When a company says it has “resolved” a government lawsuit and “reaffirmed” a partnership, the instinct is to read a win. The settlement Zillow and Redfin struck with the Federal Trade Commission is being sold exactly that way. It is closer to the opposite: a regulator forcing two companies to rebuild the competitor they had agreed to make disappear.

The framing matters, because the remedy is unusual. There is no headline fine, no admission of wrongdoing, no dramatic breakup. Instead the government reached into the companies’ own strategy and reversed it — ordering Redfin to restart, staff and fund a business it had deliberately shut down, and placing both firms under supervision for years. What reads as leniency is actually the harder ask.

The deal at the center of the case was signed in early 2025. Zillow agreed to pay Redfin $100 million for the exclusive right to fill Redfin’s apartment pages with Zillow’s rental listings. In the FTC’s telling, that money bought more than syndication: it bought Redfin’s exit. Redfin wound down its own multifamily advertising business, handed its customer contracts to Zillow, and agreed to stay out of the rental-listings market for as long as nine years.

The market at issue is narrow and unglamorous — the internet listing services, or ILS, where property managers pay to advertise apartments to renters. It is also concentrated, which is why removing a competitor from it drew a complaint rather than a shrug. The FTC, joined by five states, sued last autumn, arguing that the arrangement was an illegal agreement not to compete dressed up as a commercial partnership.

The settlement’s terms read less like a truce than a work order. Redfin must relaunch its standalone rental-listings business within six months or face financial penalties. It has to hire a general manager, a sales force and a trained support team, and commit to spending millions to grow the operation. By 2027 both companies must offer standalone multifamily advertising products alongside the partnership, which can continue through at least 2030. Zillow, for its part, has to drop the noncompete clauses blocking Redfin from rehiring, and both sides must notify regulators before signing any future deal that could restrict competition — then file reports proving they complied.

There is a cost here that the celebratory statements skip. When Redfin took the money and left rentals, it cut hundreds of jobs. The settlement now requires it to rebuild much of what it dismantled — the same functions, staffed again, on the government’s clock. Daniel Guarnera, who runs the FTC’s competition bureau, put it plainly: the order “unwinds an agreement under which Zillow paid Redfin $100 million to stop competing and hand off all its customers to Zillow.” That is not the language of a partnership reaffirmed.

The read for each company is different. For Zillow, the outcome preserves the listings pipeline it paid for while conceding the exclusivity that made it valuable. For Redfin, the reckoning is sharper: it banked a nine-figure sum to become smaller, and now has to spend to become a competitor again, whether or not that fits its plans. The FTC, meanwhile, gets what it wanted without the risk of trial — a rival restored on paper and, if the order holds, in the market.

The lesson for the next platform tempted to buy its way out of a fight is quiet but expensive. The cheapest deals to sign can be the costliest to unwind — and regulators are increasingly willing to make you rebuild, brick by brick, exactly what you paid to bury.
