Zillow seeks court order to block MRED feed termination

Zillow has asked a federal court to block Midwest Real Estate Data (MRED) from cutting off access to its listing feed, calling the move a direct attempt to cripple competition. The portal filed a motion on May 18 seeking a preliminary injunction, arguing that MRED and Compass — a real estate brokerage — colluded to exclude Zillow from critical data, which would harm buyers, sellers, and the broader market. MRED countered that Zillow is in breach of its agreement, claiming the portal violated rules by suppressing certain listings on its platforms.

The dispute centers on Zillow’s access to MRED’s listing feed, which provides data for Zillow.com and Trulia.com. MRED set a deadline: the portal must fix its alleged violations by Tuesday, May 19, 2026, or face suspension of its data feeds. The MLS also warned it could terminate the portal’s license if it continued to hide listings that violate MRED’s policies, including a ban on pre-marketed listings. Zillow claims it has not enforced its listing standards in the Chicago area to avoid losing access to MRED’s data.

Zillow’s lawsuit, filed earlier in May, alleges that MRED and Compass conspired to prevent the portal from enforcing industry-wide listing access standards. The company argues that by threatening to cut off its data, the two entities are forcing it to abandon transparency measures that benefit consumers. Zillow’s motion for an injunction highlights what it calls “irreparable harm” if its access is terminated, including reduced competition and distorted market dynamics.

According to the motion, Compass CEO Robert Rehmar and MRED President Rebecca Jensen sent emails warning the portal of potential feed suspensions if it did not display certain Compass listings nationwide. Days later, Compass and its subsidiaries terminated the portal’s direct feed access. A Compass broker also reported that MRED officials had informed them the portal would be barred from receiving listing feeds entirely.

MRED emphasized in a news release that its rules apply equally to all participants, regardless of platform size. The MLS said it hopes the portal will comply with its IDX and VOW (Visible On Website) rules to avoid disruptions. MRED also noted that if the portal’s feeds are suspended, MRED listings will remain accessible on thousands of other compliant websites, while Zillow Group brands like ShowingTime and dotLoop would not be affected.

Zillow’s legal team has cited economic analysis to support its claims. Lawrence Wu, an economist with NERA, testified that MRED and Compass hold significant market power due to their control over listing data. Wu argued that by threatening to cut off the portal’s access, the two entities could effectively pressure it to abandon transparency standards, which are central to its services. His 94-page declaration outlines how such actions may hinder competition and limit consumer choice.

Zillow’s motion also highlights the potential impact on its “Preview” service, a new platform aimed at helping buyers find homes. The filing states that cutting off the portal’s Preview access to MRED listings would reduce its ability to compete with established players like Compass, which operates its own brokerage. Zillow argues that the threat of feed suspension undermines its investments in technology and customer service, which are designed to benefit brokers, agents, and homebuyers.

The outlet has contacted Compass for comment, but the company has not yet responded. MRED’s stance remains firm: it will enforce its rules consistently, regardless of the size or reach of the platforms involved. The MLS stressed that compliance is the portal’s choice, but warned that noncompliance could lead to broader market disruptions.

The case raises broader questions about the balance between data control and competition in the real estate industry. If the court sides with the portal, it could set a precedent for how MLSs and brokers manage access to listing data. If not, it may reinforce the authority of MLSs to enforce rules that prioritize local market needs over national platforms. The outcome could shape the future of real estate technology and consumer access to market information.
