Северо-западная служба множественного листинга has filed counterclaims in federal court against Компас, alleging the brokerage’s “three-phase marketing program” is a deceptive scheme that hides listing data from the public and violates Washington’s Consumer Protection Act.
In the filing, the Kirkland, Wash.-based MLS argues that Compass’ strategy of scaling so-called “pocket listings” creates a “two-tier” marketplace, with fuller access for Компас-affiliated buyers and a depleted set of options for the general public and competing brokers. The counterclaims were filed in a federal case in which Compass is a plaintiff and NWMLS is a defendant.
“Across the country, we are seeing a clear trend that consumers want more choice, transparency and flexibility, and are pushing back on industry-imposed mandates,” according to a Compass spokesperson. “We stand with consumers, real estate professionals, homeowners, homebuyers and competition.”
Washington law now mirrors NWMLS listing rules
NWMLS said in its filing that its long-standing listing transparency rules have effectively been written into state law. Senate Bill 6091, which takes effect in June, requires brokers in Washington to market properties broadly to the public and to other brokers.
That standard — open, public marketing of residential listings rather than limited exposure to select buyers or internal networks — has been a core rule of the broker-owned MLS for decades, the organization said in the counterclaim.
For brokers and teams operating in Washington, the combination of MLS rules and SB 6091 means marketing strategies built around off-MLS exposure or extended private “coming soon” promotion will face heightened legal and regulatory risk once the law is in force.
Allegations: data manipulation and reduced seller proceeds
NWMLS’ counterclaims center on three main allegations about Compass’s “three-Phase Marketing Program” and related practices:
- Resetting market history: The MLS alleges Compass “wipes the slate clean” by artificially resetting days-on-market and price history when a property moves from off-market phases to the open market, which NWMLS says misleads buyers about true demand for a home.
- “Pocket listing” tax on sellers: By limiting exposure to internal or exclusive groups, NWMLS argues Compass suppresses the “public auction” effect of broad marketing that typically drives higher sale prices. The counterclaim cites data from Compass partner Красноперый showing homes sold off-market generally sell for less than comparable MLS-listed homes.
- Contract interference: NWMLS alleges Compass encouraged and incentivized its brokers to violate professional agreements with the MLS in order to prioritize corporate growth over transparency and consumer interests.
Justin Haag, CEO of NWMLS, framed the case as a broader test of how residential inventory is shared and monetized.
“This case is about more than just MLS rules; it’s about putting people over corporations,” Haag said in a statement. “We are standing up for the principle that every family has the right to see every home for sale, because housing data belongs in the sunlight, not in a private vault. It is time to make the housing market more equitable for everyone instead of simply making real estate CEOs richer.”
According to a Compass spokesperson,
“Instead of focusing on solutions that benefit consumers and promote competition, NWMLS is retaliating against us for exposing its illegal scheme to deprive homeowners of their rights and block competition. This is how monopolists like NWMLS treat their customers. NWMLS is not focused on serving consumers, or even the real estate professionals who rely on it.”
Why this matters for brokers and consumers
The dispute underscores growing legal and regulatory scrutiny of listing access, data transparency and the use of off-MLS marketing channels. Pocket listings, private networks and extended “coming soon” periods have been popular with some brokerages and teams seeking differentiation or exclusivity.
For brokers and agents, the NWMLS action signals that enforcement around off-MLS strategies in Washington is likely to tighten as SB 6091 comes online. Firms may need to review pre-market and internal marketing programs, listing agreements and compliance policies to ensure they align with both MLS rules and state consumer protection law.
For consumers, the case will help define how much listing data must be shared and how quickly, and whether private networks that restrict access to inventory can coexist with emerging state mandates for broad, public marketing of homes for sale.
