Gary Keller is warning that the industry’s shift toward private listings and pre-marketing strategies could undermine the MLS system and distort how homes are priced.
In a video shared on Keller Williams’ YouTube channel, company co-founder and chairman Gary Keller took aim at the idea that private marketing creates beneficial scarcity for sellers, arguing instead that limited distribution can restrict competition and shift control over market information toward brokerages.
Keller said the industry should be more precise about what “private” means when listings are shared across large internal brokerage networks.
“What this really is is selected distribution with restricted access,” Keller said. “The listing isn’t hidden. It’s just being shared with a chosen group instead of the entire market. And that distinction matters, because the next claim depends on it: Does privacy create real scarcity?”
Keller argued that scarcity in real estate has traditionally referred 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 issue isn’t whether people know — it’s which people know, and who gets to decide who knows. It’s a preference for controlled visibility,” Keller said.

The remarks come as Compass’ push to expand its 3-Phased Marketing Strategy and Private Exclusives inventory has forced a broader industry debate over seller choice, MLS participation and brokerage-controlled inventory. Compass has argued that sellers should have more control over how their homes are brought to market, while critics say the strategy could limit exposure, advantage large brokerages and weaken the MLS system.
Keller did not reject seller choice outright, but argued that choice alone does not mean a strategy is good for sellers. Agents, he said, have a professional obligation to clearly explain the tradeoffs involved, including any incentives that may benefit the agent or brokerage.
Keller also warned that widespread use of private marketing could weaken the role of MLSs if brokerages increasingly use them only after a listing fails to sell internally.
“If every broker starts holding their listings back and only turns to MLS when nothing else works, what does MLS become? It becomes the market of last resort, the place where properties go after everything else has failed, leftovers, remnants,” Keller said.
Keller said feedback, preparation and sequencing can still be useful parts of a listing strategy. But he argued those tactics can be used within an open marketplace, rather than as a substitute for full exposure.
“These aren’t new ideas,” Keller said. “But if the goal is to give sellers the highest probability of achieving the best possible outcome, there’s still one mechanism that consistently delivers that result: broad exposure that creates the opportunity for real competition.”
Keller framed the debate as a defining test for the industry, warning that the spread of private listing strategies could fundamentally change how the housing market works — moving it away from shared information and open competition and toward selective access controlled by individual brokerages.
Ultimately, this shift could lead to the end of the open marketplace, he warned.
“There’s actually an economic term for this called information asymmetry,” Keller said. “Information asymmetry occurs when one party in an economic transaction possesses greater material knowledge than the other, leading to potential market inefficiencies and imbalances of power, and in severe cases, market failure.”
