OneKey MLS rejects Compass demand on public listings

OneKey MLS has rejected a demand from Compass International Holdings to change its rules on publicly marketed listings, setting up a new flashpoint over whether homes advertised to the public must be placed in a shared multiple listing service or can be held inside private brokerage networks.

The New York-based MLS, which serves the Hudson Valley, Long Island and New York City, said Compass sought the ability to advertise homes for sale while keeping them out of the OneKey database. OneKey is framing the dispute as a test of whether the real estate marketplace remains open and cooperative or fractures into firm-controlled systems.

“A truly competitive real estate marketplace relies on shared, cooperative infrastructure, not fragmented, private networks,” Richard Haggerty, CEO of OneKey MLS, said in the statement. “Withholding inventory from the open marketplace comes at the direct expense of consumers by restricting buyer access and potentially limiting a seller’s return on their investment. Consumers deserve the freedom to work with the professional they trust without being limited to one company’s private inventory. That cooperative model creates equal opportunity, and those fundamental protections are worth defending.”

What Compass is seeking and how OneKey’s rules work

OneKey said Compass has framed its request as a matter of “seller choice,” but the MLS characterized it as a fundamental change: allowing listings to be promoted publicly while remaining outside the shared system that other brokerages rely on.

OneKey said its rules already allow for multiple marketing paths, including options that restrict public exposure to protect seller privacy. The organization argued that Compass’s proposal goes further by enabling a single firm to act as a gatekeeper over who can see certain homes and which competing agents can bring buyers.

“Real estate firms should earn a home buyer’s or seller’s business through better service not by restricting access to the local housing supply,” OneKey said.

The MLS emphasized that its policies are based on reciprocity and apply across the board. Participants collectively shape rules through an established process, OneKey said, and no special treatment is given to large brokerages. At the same time, firms that benefit from the shared inventory must also contribute their publicly marketed listings to the common pool.

Why this matters for brokers, teams and consumers

The standoff highlights a key competitive question for broker-owners, team leaders and agents: Will publicly marketed listings in major markets like New York remain visible to all MLS participants, or will large firms increasingly keep inventory inside their own private ecosystems?

This comes as MLSs nationwide adjust listing policies in response to commission lawsuits, decoupled compensation and heightened regulatory scrutiny. Many have strengthened “coming soon” and public marketing rules to ensure that once a property is publicly advertised, it must be submitted to the MLS within a specified time frame. At the same time, major brokerages have leaned into office exclusives, “private collection” offerings and tech-enabled internal networks.

OneKey linked Compass’s request to the financial outcomes sellers achieve and to agents’ fiduciary duty to secure the best possible result for clients. The MLS cited data and argued that limiting a home’s exposure weakens competitive bidding and suppresses true market value, undermining the duty agents owe their clients when “seller choice” is used to justify restricted marketing.

Fair housing and regulatory backdrop

Beyond price and competition, OneKey tied private listing networks to fair housing and equal access concerns, warning that fragmenting publicly marketed properties across closed ecosystems creates barriers for many buyers.

The MLS also cited several external developments, including Sens. Elizabeth Warren and Cory Booker, recently urging the Federal Trade Commission (FTC) to investigate anticompetitive and deceptive practices in the online homebuying marketplace, specifically highlighting the use of private listings and NAACP President Derrick Johnson describing private listing networks as a “modern form of digital redlining” and said defending open access to housing inventory is “more than an industry dispute” and instead a civil rights issue.

OneKey also argued that when some consumers see listings and others do not, based on whether they are plugged into a particular brokerage’s network, it “systematically shuts out minority and first-time buyers from equal homeownership pathways.”

These concerns arrive as regulators and advocates focus more broadly on how digital platforms, algorithms and off-MLS practices can create disparate outcomes, adding another layer of risk to strategies that limit listing exposure.

Broader implications for MLS governance

OneKey’s response signals that MLS governance around inventory sharing is likely to become a more active battleground alongside compensation and buyer agency rules. As large brokerages build proprietary tech and data platforms, MLSs are under pressure to demonstrate that cooperative systems still deliver clear advantages for participants and consumers.

While OneKey said it supports “industry innovation,” it said it will oppose any efforts that weaken the reciprocal framework at the center of the MLS model, calling such moves “a dangerous step backward to a less transparent era, where housing access depended entirely on who you knew.”

The MLS said it remains committed to a system where seller privacy options and broad access can “work together.” 

In an emailed statement, a Compass spokesperson told HousingWire that the issue it sees with what OneKey and other MLSs are arguing is that “they make a collection of competitors the judge, jury, and executioner for how agents compete, and take away from homeowners the freedom to make informed decisions for themselves.” 

OneKey is joining both Unlock MLS in Austin and California Regional MLS (CRMLS) in its rejection of Compass’s demands. 

All three MLSs have rejected these demands despite threats from Compass CEO Robert Reffkin that his firm would sue any MLS that did not give in. On Friday, Compass carried out this threat, filing a lawsuit against CRMLS alleging that its rules unlawfully restrict how homeowners and their agents can publicly market properties outside the MLS. Compass has said it plans to file a similar lawsuit against Unlock MLS.
