On September 15, 2026, a federal judge in Chicago denied Zillow's request to stop Midwest Real Estate Data (MRED), the multiple listing service behind most Chicagoland home sales, from enforcing its listing rules against the portal. Judge John Tharp also ordered Zillow's core claims against MRED into private arbitration, moving a fight that started with a blacked-out listing feed in May into a process that will play out mostly behind closed doors. Here is what happened, why MRED and Zillow ended up here, and what it actually means if you are buying or selling a home in Chicagoland right now.
Quick takeaways
- Zillow's listings are still live in Chicago today. Nothing changes immediately for buyers or sellers.
- MRED has said it is prepared to cut Zillow's feed again if it believes its rules are being violated.
- The dispute is really about how and when private, pre-market listings show up on public portals.
- The next steps happen in private arbitration, so a public resolution could take a while.
What happened
The dispute goes back to this spring. In April 2026, MRED announced an expansion of its rules with support from Compass. By May, Zillow had sued both MRED and Compass, and MRED moved to shut off Zillow's access to its listing feed, arguing Zillow had broken its license agreement. A court stepped in temporarily to keep listings flowing while the case played out.
That temporary truce ended on September 15. Judge Tharp declined to grant Zillow the injunction it wanted and ruled that MRED's contracts with Zillow require the dispute to go to arbitration rather than federal court. In his ruling, Tharp wrote that "Zillow has not made the required strong showing that MRED and Compass agreed to cut off Zillow's access" to listings, and separately noted that "transparency is not, standing alone, a goal of the antitrust laws." Zillow's claims against Compass specifically are paused until the arbitration concludes.
MRED called the ruling a win for "fundamental MLS principles" and the ability of MLSs to "consistently enforce their rules." Compass said the decision affirms that "choice belongs to the homeowner." Zillow, for its part, has stressed this is "not a final ruling on the merits" and said it is still evaluating next steps.
Why MRED and Zillow are fighting over your listings
Underneath the legal language, this case is about how homes get marketed before they hit the open market. Some brokerages, including Compass, offer sellers a phased approach: a listing can be shared privately within the brokerage's own network for a period before it is broadly syndicated to public portals. MRED's rules say every participant has to follow the same objective criteria for how listings are shared, a standard that traces back to a 2008 Department of Justice settlement with the National Association of Realtors limiting MLS filtering to neutral factors like price, location, and property type. Zillow has had a policy of not displaying listings that were previously marketed privately elsewhere before landing on the open MLS. MRED views that policy as Zillow picking and choosing which listings to show based on where they came from, rather than applying the same rules to everyone. That disagreement is what led MRED to cut Zillow's feed in May, and it is the same disagreement now headed to arbitration.
What this means for Chicagoland sellers
If your agent offers a private or "coming soon" marketing phase before a listing goes fully public, it is worth asking exactly where your home will and will not appear during that window, and for how long. Portal exposure and a more controlled rollout both have real value, and the right choice depends on your goals for the sale. This ruling does not resolve which approach wins out, so the clearest thing a seller can do right now is have that conversation with their agent up front, not after the listing goes live.
What this means for Chicagoland buyers
Zillow's Chicago listings are active today, and that is not expected to change overnight. What is worth knowing is that MRED has said it is ready to disconnect Zillow's feed again if it believes its rules are being broken, which is exactly what happened in May. Buyers who search on a single app run the risk of missing homes that are being shown privately first, or losing access to a portal's listings altogether if another cutoff happens. The most reliable way to see everything available in Chicagoland, including homes marketed privately before they go fully public, is to work with an agent who has direct MRED access rather than relying on one app alone.
What happens next
Because the case is moving to private arbitration, the public is unlikely to see a detailed ruling on the underlying rules anytime soon. Watch for two things: whether Zillow adjusts its policy on displaying previously private listings, and whether MRED follows through on cutting Zillow's feed again if it finds new violations. Either move would have an immediate, visible effect on what Chicagoland buyers and sellers see on the app.
Common questions about the Zillow-MRED ruling
Is Zillow going away in Chicago?
Not based on this ruling. Zillow's Chicagoland listings remain active. The case sends the dispute to arbitration rather than shutting anything down immediately, though MRED has said it could cut the feed again if it finds rule violations.
What is MRED?
Midwest Real Estate Data is the multiple listing service that most Chicago-area brokerages use to share listing information with each other and with public sites like Zillow.
Why did MRED cut off Zillow's listing feed?
MRED said Zillow violated its license agreement by not displaying certain listings the same way it displays others, specifically homes that were marketed privately before going fully public. MRED requires all participants to follow the same objective rules.
Does this affect how my home gets marketed?
It could affect where and when it appears online if your agent uses a private or phased marketing approach. Ask your agent to walk you through the timeline before you list.

The bottom line for Chicagoland
This is a legal and business fight happening above the level of any single transaction, but it touches something very real for buyers and sellers here: how complete a picture you get when you search for a home online. For full transparency, our team operates under Compass, one of the parties named in this case, which is exactly why we think it is worth explaining plainly rather than picking a side. Whatever happens in arbitration, the fundamentals of a good Chicagoland home search have not changed. Work with someone who has full access to what is actually on the market, ask questions about how a listing will be marketed before you sign anything, and do not assume one app shows you everything. If you want to talk through what this means for your specific plans to buy or sell in Logan Square, Bucktown, Humboldt Park, Lincoln Park, Andersonville, or Ukrainian Village, we are always happy to walk through it with you.
