House Antitrust Panel Probes Compass-MRED Listing Network

A House Judiciary subcommittee sent letters on July 22, 2026, to Compass CEO Robert Reffkin and MRED President and CEO Rebecca Jensen, seeking explanations for their nationwide private listing network partnership. The Subcommittee on the Administrative State, Regulatory Reform and Antitrust, chaired by Rep. Scott Fitzgerald, R-Wis., expressed concerns that the arrangement could reduce transparency, stifle competition, and negatively impact homebuyers and sellers. The panel is examining whether real estate companies are utilizing private listing networks (PLNs) and similar structures to create insulation from competition, thereby undermining U.S. antitrust laws.

This investigation follows an April announcement where MRED, a major multiple listing service, partnered with Compass to broaden its Private Listing Network beyond its traditional Midwest service area. The agreement allows MRED to offer "off-MLS listings" not accessible to the broader public. Compass, in turn, markets these properties as "Compass Private Exclusive" listings, initially sharing them within its own agent network before they are listed on public platforms like Zillow, Redfin, or Realtor.com, or local MLSs. Compass also has a separate exclusive agreement with Redfin for pre-marketing "coming soon" listings.

The subcommittee highlighted several potential competitive issues arising from the Compass-MRED structure and PLNs in general. These include a reduction in transparency and fragmentation of property inventory. Lawmakers referenced industry observations suggesting that PLNs can confine listing information within closed systems, making it more difficult for potential buyers who lack access to these networks to discover available properties. This fragmentation could lead to a less efficient market and potentially higher costs for consumers.
