Well, we did not have to wait long to find out whether the growing fight between Compass and California Regional MLS was mostly tough talk or headed for an actual courtroom. CRMLS filed a federal lawsuit against Compass on October 5, beating Compass to court by one day after Compass had given the MLS an October 6 deadline to change its rules or face an antitrust lawsuit. That turns what had been an increasingly hostile argument over private listings and MLS cooperation into a real federal case.
CRMLS filed the case in the United States District Court for the Southern District of New York, where Compass is headquartered. Rather than waiting to defend itself against the lawsuit Compass had threatened, CRMLS is asking the court for a declaratory judgment that its cooperation rules are lawful and do not violate federal or California antitrust law.
That may sound like procedural maneuvering, but I think it is more important than that. CRMLS has essentially decided that if Compass wants the legality of the cooperative MLS model tested in federal court, CRMLS is willing to have that question answered now and is not going to let Compass control when the fight starts or how the issue is framed.
A few days ago I wrote about the underlying dispute in For Sale, But Not to You? The Fight Over Private Listings and Buyer Access. At the time, Compass had demanded that CRMLS stop penalizing agents who publicly market certain listings while withholding them from the MLS, and CRMLS had responded by rejecting that demand and making clear it was prepared to fight.
Compass’s argument continues to center on seller choice. A seller owns the property and, according to Compass, should be able to choose not to submit the listing to the cooperative MLS while still allowing the brokerage to advertise the property publicly through other channels. Compass argues that an MLS should not be able to restrict that marketing simply because the brokerage and its agents participate in the MLS.
There is an argument there worth taking seriously. MLS rules should be scrutinized, particularly when they affect how brokers compete or how sellers market their properties. Antitrust laws apply to MLS organizations just like they apply to everyone else, and the word cooperation does not automatically make every MLS rule reasonable or lawful.
But I still think that framing leaves out half of the equation. The question is not merely whether a seller can choose how a property is marketed. The question is whether a brokerage can take full advantage of a cooperative marketplace built from its competitors’ listings, data and participation while publicly marketing some of its own inventory outside that marketplace and restricting access to it.
That is the issue CRMLS now wants a federal judge to address. CRMLS maintains that its rules are intended to preserve a marketplace where participating brokers cooperate with one another and where publicly marketed properties are not selectively withheld from the other brokers participating in that system.
Compass views those restrictions as interference with seller choice and competition. CRMLS views the Compass model as allowing a brokerage to benefit from the cooperative inventory contributed by everyone else while building a separate pool of inventory that it can control itself.
I think that distinction is going to be critical as this case develops. If Compass were simply advocating for sellers who genuinely want privacy, I would have very little disagreement with the concept. There have always been sellers who do not want broad exposure for legitimate personal reasons, and there should be ways to accommodate them.
But once a property is being promoted to the public, we are no longer really talking about privacy. We are talking about distribution and access. Who gets to know the property is available, who gets to show it, and whether the buyer can continue using the real estate professional that buyer selected are very different questions.
That is why I continue to believe the buyer side of this debate is not getting enough attention. Sellers are consumers, but so are buyers. A buyer who has hired an experienced agent should not have to wonder whether choosing that agent means losing practical access to homes controlled by another brokerage.
The lawsuit also makes this much bigger than one disagreement between Compass and a California MLS. Compass has made clear that its objections are not limited to CRMLS and has threatened litigation against other MLS organizations with similar policies. CRMLS, meanwhile, has been organizing support for an MLS Cooperation Legal Defense Fund and has framed this as a fight over the future of the cooperative marketplace itself.
That makes this worth watching nationally. If Compass ultimately establishes that rules like these violate antitrust law, MLS organizations around the country could be forced to reconsider how they deal with publicly marketed listings that are withheld from the MLS. If CRMLS prevails, the decision could provide substantial support for the principle that participation in a cooperative marketplace can come with meaningful obligations to cooperate.
There is also something refreshing about getting this issue out of press releases, conference stages and demand letters and into a place where each side will eventually have to support its legal position with evidence and law. Compass has made serious allegations about competition and seller choice. CRMLS has made equally serious arguments about free riding, equal access and the future of the cooperative model.
Let a court sort out which restrictions are lawful and which are not. What I hope does not get lost along the way is the larger question of what kind of real estate marketplace we want when this is over.
For decades, one of the strengths of the MLS system has been that a small independent brokerage could compete with the largest company in town because the inventory was not supposed to belong to any one brokerage. Brokers competed for clients, but once properties entered the cooperative marketplace, agents could work across company lines to put buyers and sellers together.
If we move instead toward a system where the largest companies build increasingly valuable proprietary pools of inventory, the competitive advantage begins shifting away from service, knowledge and representation and toward control of the homes themselves. I still have a difficult time seeing how putting more walls around housing inventory ultimately produces more competition for consumers.
CRMLS has now decided it is willing to ask a federal court essentially that same question. Compass wanted a legal fight over these rules, and unless something changes quickly, it now has one.
This could become one of the more consequential real estate lawsuits to watch because the ultimate issue is much larger than whether one MLS can issue a fine. It is about whether the MLS remains a cooperative marketplace in which competing brokers share inventory, or whether the industry gradually moves toward competing networks where access to homes increasingly depends upon which company controls the listing.
