A federal judge in Chicago just handed Compass a win in its fight with Zillow, and the ripple effects could change where your buyers actually find their listings.
On Sept. 15, U.S. District Judge John J. Tharp denied Zillow's request for a preliminary injunction against Midwest Real Estate Data (MRED), the Chicago-area MLS at the center of a year-long antitrust fight involving Zillow, MRED, and Compass International Holdings. The court found that MRED's listing syndication rules didn't violate antitrust law and that MRED hadn't entered into an unlawful boycott of Zillow alongside Compass, according to reporting from Real Estate News. The case isn't over. The court has directed the parties toward arbitration, and no final ruling has been made. But the early read has emboldened both sides to make their next move.
What Compass Did Right After
A week after the ruling, on Sept. 22, Compass rolled out a redesign of Compass.com under a new banner: "See It First." The company says the site now pulls listings from every stage of marketing, across all nine of its brands, into one place, without showing days on market or public price drops. Compass says buyers do not need to work with a Compass agent to view the listings that are searchable there, though that appears to apply mainly to homes in the coming-soon phase. Fully private "Compass Exclusives" still route interested buyers through a registration link before they get connected to an agent.
In New York, where Compass is headquartered, the company has gone further. Earlier this month it began offering a $1,000 digital marketing package to New York City agents who pull active and in-contract listings off Zillow-owned StreetEasy, the metro's leading search portal, as reported by Real Estate News on Sept. 16.
Why This Matters Beyond Chicago and New York
Industry observers cited by Real Estate News have floated something bigger: Compass angling to become one of the industry's dominant listing portals in its own right, and Zillow moving to look more like an MLS. That is not a new idea. Compass International Holdings Chairman and CEO Robert Reffkin said at NAR NXT back in 2024 that "Zillow is going to be the MLS. It's only a matter of time." What is different now is that a court just declined to slow that trajectory down, at least for the moment.
For agents outside those two markets, the practical question is simpler: where does your seller's listing get the most eyes, and does your brokerage's marketing strategy line up with what that seller actually wants. A three-phase rollout, coming soon to exclusive to open market, can work well for the right seller. It can also mean fewer buyer agents outside your brokerage ever see the home during the window that matters most.
What To Watch Next
Zillow has not said publicly how it plans to adjust its listing access standards in response to the ruling. In a blog post after the decision, the company said only that it "remains committed to fighting for a fair and transparent housing market," according to Real Estate News. Watch for guidance from your own MLS on syndication rules, and do not assume the rules that applied to a coming-soon listing in July still apply today. They have already changed once this year, and this ruling makes it more likely they change again.
Key Takeaway
This fight is about who controls the pipes buyers use to find homes, and it is not settled. Until arbitration plays out, the safest move is to keep your sellers informed about exactly where their listing will and will not be visible at each stage of marketing, and to check your MLS's current syndication rules before you promise a seller a specific outcome.
