Chairman Keller Williams asserted, “The question is not whether people know, but what they know, and who decides who knows.”
Gary Keller warns that the industry’s shift to private listings and pre-marketing strategies could undermine the MLS system and distort home pricing.
In a video shared on Keller Williams’ YouTube channel, Gary Keller, the company’s co-founder and chairman, zeroed in on the idea that private marketing creates scarcity that is beneficial to sellers, arguing instead that limited distribution can limit competition and shift control of market information to intermediaries.
Keller said the industry needs to better understand what “non-public” means when property information is shared among large internal brokerage networks.
“This is really a selective distribution with limited access,” Keller said. “The list is not hidden; it is only shared with a select group, not the entire market. And that distinction is important because the next argument depends on it: Does privacy create true scarcity?”
Keller argued that real estate scarcity traditionally refers to the number of homes available to buyers or the number of buyers available to sellers, not the number of people who know a property is for sale. He said the core question is who gets early access and who decides.
“So the question is not whether people know. The question is who do people know and who gets to decide who knows. It’s a preference for controlled visibility,” Keller said.

The comments come as Compass’s three-tiered marketing strategy and push to expand its inventory of private exclusive products has forced broader industry-wide discussions about seller selection, MLS participation, and broker-managed inventory. Compass argues that sellers should have more control over how their homes are brought to market, while critics say the strategy could limit exposure, favor large brokerages and undermine the MLS system.
Although Keller did not completely reject seller choice, he argued that choice alone does not necessarily mean a strategy is good for sellers. He said agents have a professional obligation to clearly explain the trade-offs involved, including any incentives that may benefit the agent or intermediary.
Keller also warned that if brokerages increasingly use private marketing only when internal sales of listed properties fail, private marketing could become widely used and weaken the role of MLSs.
“What will happen to the MLS if all brokers start holding back on listings and only turning to the MLS when nothing else works? The MLS becomes the market of last resort, the place where real estate goes after everything else fails and there’s no leftovers or leftovers,” Keller said.
Keller said feedback, preparation and sequencing can still be a useful part of a listing strategy. But he argued that these tactics can be used within open markets, rather than as a replacement for full exposure.
“These are not new ideas,” Keller said. “But if the goal is to give sellers a high probability of achieving the best possible outcome, there is still one mechanism that consistently delivers that outcome: broad exposure that creates real competitive opportunities.”
Keller cast this debate as a defining test for the industry, warning that the proliferation of private listing strategies could fundamentally change the way housing markets work, moving them from shared information and free competition to selective access controlled by individual brokers.
Ultimately, he warned, this change could lead to the end of public markets.
“In fact, the economic term for this is information asymmetry,” Keller says. “Information asymmetry occurs when one party to an economic transaction has more material knowledge than the other party, leading to potential market inefficiencies, power imbalances, and, in severe cases, market failure.”
