The Home You Want Might Not Be on Zillow. Here’s Who’s Hiding It, and Why | Mortgage Rates, Home Loan Guides & Expert Insights
Most homes listed by real estate agents are entered into a regional multiple listing service, or MLS, where they can be seen by other agents and distributed to portals like Zillow. But some sellers agree to keep their homes outside the system, limiting who can see them and where they are advertised.
Congress is now asking some of the biggest players in real estate why more listings are moving through those private channels. On July 22, the House Judiciary Subcommittee sent letters to the CEOs of Compass and Midwest Real Estate Data, or MRED, the Chicago-area MLS, requesting briefings on their private listings partnership.
The Washington side of that story will likely continue for months. The part that matters to buyers is already true. the portal you check every morning may not show you the entire market.

How Compass and Zillow Ended Up in Court
compass, the country’s largest brokerage company by sales volumebuild a three-phase strategy keep around lists at home before they hit the open market.
A seller may first offer a home as an exclusive office, meaning the property is only visible to brokerage agents and clients. It can then be advertised as a “coming soon” listing through the company’s network or website before eventually being entered into the MLS.
That strategy backfires National Association of Realtors Clear cooperation policy. By rule, when an agent publicly markets a property, the listing must usually be submitted to the MLS within one business day. The policy was designed to prevent homes from being advertised publicly while remaining unavailable to agents and buyers outside the private network.
Zillow responded creating access standards that prohibit listings on its site if they were publicly marketed but not widely used. The company argues that allowing homes to be privately traded fragments the market and makes it difficult for buyers to see all of their options.
The dispute escalated in May 2026when Zillow sued Compass and MRED, One of the nation’s largest MLSs serving the Chicago metro areain the Northern District of Illinois, alleging the two conspired to threaten Zillow’s access to the listings.
Compass responded procedurally by filing complaints against Zillow’s standards 26 states, 55 MLS and 30 real estate associations.
As of press time, the court has not ruled on a preliminary injunction on Zillow’s lawsuit. a two-day court session was held at the beginning of July, on which a decision was made. An earlier temporary restraining order in May required MRED to reinstate the Zillow listing update while the case is pending.
in july NAR has published new guidelines clarifying what brokers must disclose when a seller selects office exclusive or premarketing. And on July 22? House Judiciary Subcommittee on Administrative Affairs, Regulatory Reform, and Antitrust Asked Compass CEO Robert Refkin and MRED CEO Rebecca Jensen for briefings, warning that the partnership would “create a closed information system for some property listings” and “raised concerns about the information available to consumers and the impact this could have on housing affordability”.

What Zillow and Compass Everyone Should Get
In this fight, everyone claims to protect consumers. Zillow says buyers are harmed when inventory is split between separate private networks. Compass says sellers should have more control over how and when their homes are marketed.
Zillow’s business depends on where buyers can go to see nearly every available home, so transparency and comprehensive maintenance of its platform lead to the same result. Compass benefits when buyers need a Compass agent to access listings that are only available within its network.
Neither company is wrong about the other’s incentives. That makes the dispute useful to watch, but there’s little reason for buyers or sellers to take sides.
What do private listings mean for home buyers?
Come to thiscake with the assumption that many buyers have. if it’s for sale, it’s on Zillow. For about a decade, that was close enough to the truth. This is not the case at the moment, and the gap is largest in markets where Compass has heavy agent share.

Why Buyers May Skip Homes for Sale
A house kept as an exclusive office or circulated as private “soon” can be toured, negotiated and sold without ever generating a portal notice. You won’t know what you haven’t seen.
Chicago is a living test case. MRED serves one of the nation’s three largest markets, and its partnership with Compass is exactly what the lawsuit and congressional letters are targeting. If you search there, some of the inventory today moves through private channels.
Why no agent has access to every list?
If you work with a large brokerage, the sword cuts both ways. A Compass buyer’s agent can show you a private Compass inventory before the public sees it, which is a real plus.
That same agent does not have a special window into the hidden listings of competing brokers. No one has the whole picture anymore. This is the real cost of this arms race. it’s not that one company wins, but the complete visibility of the market ceases to be what any single search or any single agent can give you.
What do private listings mean for home sellers?
If you’re selling, what you may have heard is that a private launch offers exclusivity, privacy and the ability to test your price without clocking market days.
These are real benefits in specific situations, and seller privacy is a legitimate interest, not a smokescreen.
The compromise is disclosure. Fewer eyes on the listing indicate fewer competing offers.
NAR’s July guidance now requires brokers to clearly walk you through that trade-off before you sign an exclusive contract for an office. If the explanation you get is vague, that’s information in itself.
What to Ask Your Agent About Off-Market Homes
Business questions are up to your agentand they rightly ask during any interview. How do you display those listings that never reach the portals? What proportion of your brokerage lists start out as office exclusives? Will you proactively show me nearby inventory from other brokerages and how? With a true answer, the agent describes a process. The agent changes the subject without one.

What happens next in the Zillow-Compass battle?
Nothing about emails or claims changes what appears on your screen this month. The judge’s decision means Zillow continues to enforce its ban during the trial, Compass maintains its strategy where it legally can, and the subcommittee briefings have no deadline that would affect your search.
Developments Buyers Should Watch
Signals worth watching. Zillow v. The Compass and MRED decisions in the Northern District of Illinois, whether the congressional investigation is expanding between the two companies, and whether the NAR is tightening or loosening Clear Cooperation’s enforcement. Zillow also protects a Federal Trade Commission antitrust suit Because of its rental listings deal with Redfin, so no one is coming to the table with clean hands.
The portal was never a marketplace. It was a very good window into the market, and the glass shrinks while the companies fighting for it claim to wash it for your benefit. Knowing where the walls are is now part of buying a home. Buyers who inquire about inventory outside of the portal will see more homes than those who assume the app shows everything. That’s the whole edge, and right now it’s free.
