NWMLS is escalating its legal battle with Compass, filing a countersuit with the federal government alleging the intermediary’s deceptive listing strategy.
Northwest Multiple Listing Service is escalating its legal battle with Compass, filing a federal countersuit accusing Compass of operating a deceptive private listing strategy that harms buyers and sellers alike.
The counterclaim, filed April 2 in the U.S. District Court for the Western District of Washington, marks a turning point in the case that began last April, when Compass accused NWMLS of being a monopoly with no significant competitors. NWMLS is currently on the offensive.
The broker-owned MLS alleges in its filing that Compass’ three-tier marketing strategy (3PM) violates the Washington Consumer Protection Act and relies on misleading and exclusionary practices that benefit the broker at the expense of buyers, sellers, and competing brokers.
‘Orwellian’ strategy comes under scrutiny
NWMLS has characterized the strategy in particularly sharp terms, calling it an “Orwellian” approach that steers transactions towards Compass agents and presents itself as consumer-friendly, while restricting broader market access.
At the heart of the dispute is Compass’s gradual rollout of listings, starting with a “private exclusivity” period limited to Compass agents and customers, followed by a “coming soon” phase on Compass’ own platform, and ultimately publishing listings to the MLS. NWMLS claims that despite being labeled as “pre-sale,” these homes are effectively for sale and not available to the public.
“The private phase is a sham to gain market access at a critical time when properties are first entering the market, while simultaneously withholding listing information from buyers and other brokers who are not working with Compass agents,” NWMLS attorneys wrote in the filing.
NWMLS claims, based on Compass’ own marketing materials, that this strategy is insufficient for sellers. Listings have a 95% chance of not selling in the private stage, which is when they are sent to the MLS after a limited public viewing period.
The counterclaims also accuse Compass of withholding important information early on, including how long the home had actually been on the market and whether the price had changed. Compass calls such details “negative insights,” according to the filing. This information, which NWMLS claims is important to buyers, will be kept private when the listing is ultimately posted on the MLS.
NWMLS points directly to Compass when it comes to who benefits from a tiered marketing strategy.
“Such exclusive marketing only harms sellers, buyers, and other intermediaries, as well as benefits Compass and its intermediaries by giving them the opportunity to participate on both sides of the sale,” the filing states.
A Compass spokesperson pushed back against NWMLS’s counterclaim, calling the move retaliatory.
“Instead of focusing on solutions that benefit consumers and promote competition, NWMLS is retaliating against us for exposing an illegal scheme that disenfranchises homeowners and prevents competition,” a spokesperson said Friday. “This is how monopolistic companies like NWMLS treat their customers.”
Rule violations and governance issues become a problem
Beyond its consumer protection claims, NWMLS also accuses Compass of interfering with its membership agreements by encouraging agents to violate rules requiring listings to be submitted to the MLS and widely sold. The filing points to Compass’ long-standing role in NWMLS governance, including its recent board seat, as evidence that Compass understood these rules when it launched the program in Washington in March 2025.
Agents involved in Compass’ Seattle expansion have previously said the brokerage coordinated pre-marketing promotions and told participants the company would cover any fines associated with violations of MLS rules, details that counterclaims cite as evidence of intentional interference.
NWMLS is also suing under the new state law. Washington Acting Senate Bill 6091, signed into law in March and scheduled to go into effect in June, requires properties sold to buyers and some brokers to be made available to the general public. MLS argues that this standard reflects existing rules and would violate state law once Compass’ private phase begins.
NWMLS is seeking a declaratory judgment confirming the rule’s legality, along with damages and attorney’s fees.
Compass’ lawsuit against NWMLS last made headlines last month. In early March, NWMLS sought to rely on a legal ruling from a separate lawsuit by Compass against Zillow (which has since been dismissed). Then, in late March, a judge denied NWMLS’ request to dismiss the case against Compass.
In addition to calling NWMLS a “monopoly,” Compass on Friday also disputed NWMLS’ nonprofit status and governance structure, saying the MLS is “a for-profit corporation comprised of and controlled by competitors” and “wants to maintain tight control over the Seattle area real estate market and protect its power and funding,” resurfacing claims Compass has made since it first filed its lawsuit targeting Mr. Windermere’s representation on the NWMLS Board of Directors.
The brokerage also said NWMLS is “not focused on servicing consumers.”
“We advocate for consumers, real estate professionals, homeowners, homebuyers, and our competitors,” a Compass spokesperson further stated in an email. “We are confident that the NWMLS will fail to deter consumers and courts from illegal activity.”
