Zillow paid Redfin $100M to stop competing. The FTC undid it

The FTC settled its antitrust case against Zillow and Redfin on August 24, hours before trial. The deal at issue: Zillow paid Redfin $100 million, and Redfin stopped selling rental advertising and showed Zillow's listings instead. If you sell through an aggregator, this is the clearest recent example of what "channel risk" actually means — not the channel raising rates, but the channel's competitor being bought off.

What actually happened

Per TechCrunch's report, the FTC and attorneys general from Arizona, Connecticut, New York, Virginia, and Washington challenged a 2025 arrangement in which Redfin agreed to display Zillow's rental listings rather than compete for rental advertisers. The agreement could have run as long as nine years. The regulators' theory was straightforward: with Redfin out of the market, property managers faced higher prices and worse terms, and renters saw a thinner pool of listings.

Under the proposed order, Redfin has to re-enter rental advertising and build out its multifamily listing platform as a separate competitor. Restrictions that kept Redfin from independently pursuing property-management customers are removed. Redfin can keep displaying Zillow's listings — it just has to compete for its own customers while doing it, without sharing sensitive business information back to Zillow. CBS News reported Daniel Guarnera, director of the FTC's Bureau of Competition, framing the outcome as a win for renters and property managers.

Note what the remedy is not. Nobody unwound anything. The order forces a competitor back into a market it had agreed to leave.

Why aggregator concentration matters for your business

Your acquisition cost is set by a market you don't participate in. If two platforms own discovery in your category, the price you pay for listings is a function of whether they compete. That negotiation happens without you, and you find out about it eighteen months later in a court filing.

A second channel is not redundancy if it resells the first. Redfin was still showing listings the whole time. To a property manager checking coverage, the category looked like it had two players. It had one, plus a storefront. Test your channels by asking who actually sells the inventory, not whose logo is on the page.

Own the surface you can't be evicted from. The durable assets are your own site, your own product data, your own customer list, and structured data that any engine — human or agent — can read without a partnership agreement. Everything else is rented, and the terms of the lease are negotiated between other people.
