Coaching Tuesday: The Fight Over the MLS, and What It Means for You

Most of your buyers and sellers have no idea there's a fight going on over the future of the MLS. They're scrolling Zillow, Realtor.com and Redfin, and as far as they're concerned, the homes are just there.

But behind the scenes, the system that makes all of that work is being contested in a way it hasn't been in generations. The outcome could have significant implications for how we work, and for how agents and consumers find listings and market data. Here's a quick rundown of what's happening and what it could mean for your business.

How We Got Here

For decades, NAR's rules and the MLS were the backbone of residential real estate: one shared system where nearly every listing was posted and every agent could cooperate on it. Then the commission lawsuits hit. In March 2024, NAR announced a settlement that changed how buyer agent compensation is offered and required written buyer agreements.

The settlement didn't rewrite the MLS listing rules. But it shook NAR's standing and showed that long-standing industry policies could be successfully challenged. Now a separate fight has opened up over who controls listings.

The Main Battle: Who Controls the Listing

NAR's Clear Cooperation Policy generally requires a listing to be submitted to the MLS within one business day of public marketing. That covers yard signs, flyers, brokerage websites, email blasts, etc.

To follow this fight, it helps to separate three things that often get lumped together:

• Private listings. A seller can choose to keep a home quiet. Under NAR's 2025 policy, an office-exclusive listing is filed with the MLS but not shared with other agents or publicly marketed (NAR).

• MLS submission. Putting the listing into the MLS so every participating agent can see it and cooperate on it.

• Portal display. Showing up on Zillow, Realtor.com and other consumer sites. Under the same policy, a seller can delay that public exposure while the listing stays available to agents through the MLS.

Compass's fight is about the gap between those. It wants its agents to be able to publicly market office-exclusive listings without submitting them to the MLS, when the seller directs it. Most MLSs say that if you're publicly marketing a home, it has to go into the MLS (HousingWire).

Compass has the size to push now. In January it closed its acquisition of Anywhere, bringing Coldwell Banker, Century 21 and other brands, and their franchise networks under one roof.

This fall the legal fight escalated:

• September: Compass sent demand letters to MLSs around the country, threatening legal action unless they stopped fining its agents for publicly marketing office-exclusive listings.

• October 5: California Regional MLS, one of the largest in the country, filed in federal court asking a judge to declare its rules lawful (Real Estate News).

• Mid-October: Compass filed its own suit against CRMLS, arguing the rules unlawfully restrict how sellers can market their homes.

• October 21: Six more MLSs (Arizona Regional, Bridge, Canopy, REcolorado, Hive and Doorify) filed together in New York to defend their cooperation rules (HousingWire).

It's Not Two Clean Sides

You might expect the MLSs and Zillow on one side and Compass on the other. It’s messier than that.

Take Chicago. The region’s MLS, MRED, sided with Compass. Zillow refuses to display listings that were privately marketed before hitting the MLS, a policy Compass had already sued over in 2025. MRED told Zillow that once those listings were approved for distribution, it had to display them like any other listing or lose its Chicago feed.

Zillow sued both MRED and Compass. In September, a federal judge denied Zillow’s request for a preliminary injunction, sent its claims against MRED to arbitration and paused its claims against Compass (HousingWire). It wasn’t a final ruling, but it was a procedural win for MRED and Compass.

So some MLSs are suing Compass, and at least one is siding with it. That’s the kind of split that could lead to fragmentation.

What It Could Mean for Agents

We've all benefited from the MLS being the closest thing to one comprehensive, transparent source: one place for nearly every listing, every sale and the market data behind it. Here's what changes if that splinters:

1. Your comps get less reliable. A CMA is only as good as the data behind it. If listings and sales are scattered across private networks, you're pricing with an incomplete picture, and so is the agent on the other side of the deal.

2. More systems, more cost, same job. The work doesn't change. You'll still search, price, show and negotiate. But you could end up paying for and checking several platforms to see what used to live in one place.

3. Information becomes an advantage. Whoever holds inventory others can't see has an edge in winning listings, matching buyers and recruiting agents. That could tilt the field toward the biggest brokerages and networks.

The Silver Lining: Your Value Could Go Up

Most of what fragmentation could change makes our jobs harder. But there's another side worth considering.

For years, the knock on agents has been "I can find homes myself online." In a world where listings are scattered across private networks and different systems, that gets a lot less true. A buyer searching on their own might simply miss homes. A seller might not know which audience they're reaching, or which they're missing.

That's where a savvy agent shines: someone who knows where the inventory is, has access to the right systems and knows how to find homes that aren't on the usual sites. And unlike a lot of what we do behind the scenes, that's value the consumer can see and feel directly.

So while fragmentation would disrupt how we're used to working, it could also make a great agent more valuable than ever.

In Closing

For the first time in generations, the way our industry shares information is up for grabs. NAR's grip has loosened, Compass is pushing hard, the MLSs are split, and the courts are just getting started. It may splinter, or it may all get worked out. Nobody knows yet.

Your clients may not notice for a while. If it plays out this way, you will. Stay informed and keep an eye on your local MLS, and whichever way this goes, you'll be the agent who's ready for it.

Onward and upward!
