Zillow<\/strong> has filed a federal antitrust lawsuit against Midwest Real Estate Data<\/strong> (MRED) and Compass<\/strong>, alleging the Chicagoland MLS and the nation\u2019s largest brokerage conspired to withhold listing data and pressure Zillow to carry private \u201chidden\u201d listings nationwide, according to a company announcement.<\/p>\n

The complaint, filed on Tuesday in federal court in Chicago, accuses MRED and Compass of coordinating to threaten Zillow\u2019s access to the Chicagoland listing feed unless the portal agreed to display Compass private listings across the United States. Zillow said this conduct amounts to an unlawful group boycott and abuse of monopoly power under the federal Sherman Antitrust Act.<\/p>\n

Zillow alleges that MRED and Compass are colluding to protect and expand private listing networks that keep some homes off public portals and restrict visibility to buyers working with certain brokerages.<\/p>\n

Alleged scheme escalated after April 2025<\/h2>\n

According to the complaint, the alleged scheme escalated after April 2025, when Zillow adopted its Listing Access Standards<\/a>, which Zillow said were aimed at restricting \u201chidden\u201d or private listings on its platforms. Zillow contends Compass responded by urging multiple MLSs to cut off Zillow\u2019s data feeds unless it reversed those standards.<\/p>\n

In April 2026, MRED and Compass announced a partnership<\/a> to expand MRED\u2019s private listing network nationwide. The arrangement allowed Compass agents across the country to input listings into MRED\u2019s system. Zillow alleges that the explicit aim was to shield these listings from \u201cpro-transparency\u201d platforms and extend MRED\u2019s leverage beyond its Chicago-area footprint.<\/p>\n

By early May 2026, MRED allegedly demanded that Zillow reinstate Compass private listings in markets hundreds of miles outside MRED\u2019s traditional service area. On the same day, Zillow says, the technology provider that distributes MRED\u2019s listing feed threatened to terminate Zillow\u2019s access entirely if it did not comply. MRED CEO Rebecca Jensen chairs that distributor\u2019s board, a dual role Zillow cites as evidence that the threat and its enforcement mechanism were coordinated.<\/p>\n

Zillow says the message was clear: Either allow Compass private listings nationally or lose access to all Chicagoland listings. The company\u2019s filing cites public social media comments by a Compass agent and a response from Compass CEO Robert Reffkin as evidence that Compass knew MRED\u2019s control over the local data pipeline could be used as leverage against portals that enforce stricter listing standards.<\/p>\n

Alleged effort to go beyond Chicago<\/h2>\n

The complaint describes a broader effort to align MLS policies across regions. Zillow says a May 11 email from a Compass executive to the CEO of a North Carolina-based MLS urged that organization to \u201crigorously enforce existing policies that prevent the rise of off-MLS databases\u201d by May 20, which Zillow characterizes as a push to cut off portals that exclude certain private listings. In exchange for complying with the request, Zillow claims Compass offered to keep its listings exclusively within that MLS\u2019s territory.\u00a0<\/p>\n

Compass also announced partnerships with Realtracs<\/strong><\/a>, a Tennessee-area listing feed provider and The MLS\/CLAW<\/strong> <\/a>in California over the past few weeks. Those entities adopted rules that bar platforms from excluding listings based on a participant\u2019s identity, broker or agent, mirroring the policy shift at MRED, according to the lawsuit.<\/p>\n

The suit alleges MRED agreed to use its control over Chicagoland listing data as \u201ca weapon\u201d against portals that did not carry private listings, in exchange for Compass subsidizing MRED membership costs for up to 100,000 Compass agents nationwide. Zillow says this could triple MRED\u2019s size and expand its ability to impose rules on portals and other industry participants outside its traditional market.<\/p>\n

An ongoing spat<\/h2>\n

Friction between Zillow, MRED and Compass began over a year ago, intensifying after Zillow\u2019s roll out its Listing Access Standards, which Compass filed a since abandoned<\/a> antitrust lawsuit <\/a>over. According to the complaint, Reffkin contacted at least eight regional MLSs, arguing that MLSs should \u201cdiscipline\u201d Zillow for those rules by blocking the portal from IDX and VOW feeds if it did not reverse course.<\/p>\n

Zillow alleges that MRED leadership signaled early willingness to act<\/a>. In October 2025, Jensen allegedly warned Zillow that MRED would cut off its data access<\/a> if the portal applied its transparency standards in the region and MRED later revised its rules to support that stance.<\/p>\n

The complaint also points to broader industry effects. By February 2026, after MRED rewrote its rules but before the formal MRED\u2013Compass nationwide partnership was announced, Zillow says Redfin<\/strong> dropped a similar set of transparency standards just prior to Compass announcing its mutually exclusive deal <\/a>with Rocket<\/strong> and Redfin to publish its coming soon listings on Redfin.\u00a0<\/p>\n

Zillow is asking the court to block MRED from enforcing its revised rules and from cutting off Zillow\u2019s data access. It is also seeking treble damages and attorneys\u2019 fees.<\/p>\n

\u201cThe writing is on the wall,\u201c the complaint states. \u201cIf defendants\u2019 unlawful conspiracy is not enjoined, defendants will work to ensure no portal dares to enact similar policies to ensure transparency in real estate.<\/p>\n

\u201cCompass and MRED \u2014 two competitors in Listing Creation and Distribution \u2014 cannot conspire to boycott a competitor\u2019s access to Chicagoland listings. And MRED cannot use its monopoly power over those listings as a cudgel to prevent a competitor from effectively competing in Chicagoland or beyond.\u201d<\/p>\n

In an emailed statement a Compass spokesperson said Zillow was \u201cpunishing agents for merely following their clients\u2019 lawful instructions on how they want their homes marketed.\u201d<\/p>\n

\u201cCompass believes homeowners should have the right to decide how to market their homes. The industry is evolving to give consumers more choice and we support that progress,\u201d the spokesperson added. \u201cWe remain committed to advocating for homeowner choice and an open, competitive marketplace.\u201d<\/p>\n

MRED did not immediately return HousingWire<\/strong>\u2019s request for comment.<\/p>\n
