- CRMLS is suing Compass, seeking a judgment that its cooperation rules do not violate antitrust laws.
- Compass had threatened to sue CRMLS and other MLSs for fining agents who publicly market office-exclusive listings.
- Compass claims CRMLS's rules violate antitrust laws and seeks to prevent CRMLS from fining agents.
- CRMLS alleges Compass is trying to erode the value of the MLS for others while benefiting itself.
- Compass previously settled a lawsuit with Northwest MLS (NWMLS) over similar listing policies.
California Regional Multiple Listing Service (CRMLS) has initiated legal action against Compass, filing a lawsuit in the U.S. District Court for the Southern District of New York. The suit seeks a declaratory judgment that CRMLS's cooperation rules do not violate antitrust laws and an injunction to prevent Compass from pursuing claims against CRMLS on these grounds.
This legal move by CRMLS comes after Compass, led by CEO Robert Reffkin, had issued demands and threats to sue multiple Multiple Listing Services (MLSs) that do not alter their rules. Compass's primary contention is that MLSs should not fine agents for publicly marketing office-exclusive listings, a stance CRMLS has publicly rejected.
Industry observers like Amit Kulkarni, co-founder of Alloy Advisors, have praised CRMLS's proactive approach, contrasting it with other MLSs' tendency to either concede to such demands or ignore them. Kulkarni stated that Compass appears to be attempting to diminish the value of the MLS for other participants while benefiting exclusively from its own listings.
James Dwiggins, president of NextHome, echoed this sentiment, advocating for open litigation to address the issue. He likened Compass's actions to a refusal to share, while CRMLS claims Compass is "free riding on the comprehensive listing contributions of thousands of cooperating brokerages while hoarding its own inventory for its exclusive financial benefit."
Compass's objective, as described by some in the industry, is to control the public display of listings, particularly on its own platform, Compass.com, to drive consumers to its agents. This strategy is seen as a response to the evolving homebuying journey, where consumers increasingly find listings online before engaging an agent.
Compass has stated that its goal is simply to allow homeowners to market any listing, including office exclusives, without their agents facing fines. A company spokesperson called CRMLS's lawsuit "without merit" and indicated Compass plans to file its own suit against CRMLS.
This legal battle follows a similar antitrust lawsuit filed by Compass against Northwest MLS (NWMLS) in April 2025, which was settled with NWMLS agreeing to implement a "coming-soon" listing status. NWMLS's chief legal officer, Kelly Lennox, advised other MLSs that inaction is not a viable strategy against potential lawsuits.
