A timeline of Zillow's listing war with MRED and Compass

Zillow sought a preliminary injunction to stop MRED from terminating listing access while an antitrust lawsuit proceeds. The dispute involves Zillow Listing Access Standards and whether MRED must display all listings it supplies without selective exclusion. MRED suspended IDX and VOW listing feeds to Zillow and Trulia after Zillow allegedly refused to cure what MRED called a material breach of license agreements. MRED said its licensing agreement requires displaying all supplied listings. Zillow filed the injunction motion after MRED warned it would pull the feeds. The antitrust lawsuit alleges that a Chicagoland MLS and a major brokerage conspired to withhold listing data and pressure Zillow to carry hidden listings nationwide. Zillow’s policy restricts listings publicly marketed more than one day before appearing on IDX or VOW sites.

"Zillow filed for a preliminary injunction to block MRED from terminating listing access during an antitrust lawsuit also involving Compass. The dispute centers on Zillow Listing Access Standards and whether MRED listings must be displayed without selective exclusion."

"MRED suspended its IDX and VOW listing feeds to Zillow and Trulia after the portal allegedly refused to cure what the MLS called a material breach of its license agreements. MRED claims that, according to its licensing agreement with Zillow, the portal must display all of the listings MRED supplies it with."

"MRED had warned Zillow of its plan to pull the listing feeds earlier in the week, causing Zillow to file a motion for a preliminary injunction asking the court overseeing its antitrust lawsuit against MRED and Compass to prevent MRED from terminating its listing access while the lawsuit proceeds. The lawsuit, which was filed in mid-May alleges that the Chicagoland MLS and the nation's largest brokerage conspired to withhold listing data and pressure Zillow to carry private hidden listings nationwide."

"Both the lawsuit and MRED's decision to suspend its listing data feeds to Zillow stem from Zillow's Listing Access Standards policy, which the portal first announced in early April of 2025. The policy bans listings that are publicly marketed for more than one day before being available for display on sites powered by IDX or VOW data feeds. Just prior to Zillow beginning to roll out enforcement of its policy late last June, Compass filed a lawsuit against Zillow, claiming that the portal was breaking federal antitrust laws with its policy."
