Zillow, Compass CEOs Clash in Court Over MLS’s Uniform 2.5% Broker Fees
ZG•Zillow and Compass executives testified July 2 in Chicago federal court over allegations that Chicago-area MLS rules require uniform 2.5% broker fees and exclude Zillow’s iBuying services. Zillow CEO Richard Barton called the mandates “anti-competitive,” while Compass CEO Robert Reffkin defended the rules as vital for agent compensation.
1. Background of the Dispute
The lawsuit challenges Chicago-area Multiple Listing Service policies that set flat 2.5% commissions for buyer brokers and bar alternative models, including Zillow’s direct-purchase iBuying program. Plaintiffs argue the rules inflate seller costs and protect incumbent brokerages from competitive pricing.
2. CEO Testimonies
During the July 2 hearing, Zillow CEO Richard Barton expressed “disgust” at being excluded from the MLS network, accusing the board of preserving outdated commission structures. Compass CEO Robert Reffkin countered that uniform fees ensure reliable agent compensation and market stability.
3. Potential Impact for Zillow
A court ruling against the MLS could open access for Zillow’s iBuying service to Chicago listings and pressure other regions to revisit commission policies. Conversely, a loss risks limiting Zillow’s market reach, potentially hindering its growth and iBuying expansion plans.
