According to letters reviewed by Real Estate News, a House Judiciary antitrust subcommittee asked Compass and Midwest Real Estate Data to arrange staff briefings by Aug. 5 about their nationwide private-listing partnership. The panel’s July 22 letters ask whether the arrangement could restrict listing access or weaken competition. No violation has been found, but the inquiry could influence how brokerages and MLSs distribute private listings well beyond MRED’s Chicago-area market.
How MRED became a national listing channel
In April, MRED opened its MLS service and Private Listing Network to licensed agents nationwide. Compass became the first participating brokerage, committing a nationwide feed that includes Private Exclusive and Coming Soon listings with seller permission. The brokerage also agreed to subsidize part of the membership cost for the first 100,000 Compass agents who join.
The arrangement turns a system historically associated with the Chicago market into a potential national distribution channel. Listings submitted to MRED’s network may be visible to participating agents without appearing on public portals, depending on the listing category, seller instructions, and applicable rules.
Agents should not promise that Zillow, Realtor.com, or another consumer site displays every property available through professional listing systems. As private-listing networks expand beyond regional boundaries, buyer agents may also need access to additional MLSs or brokerage systems to identify available inventory.
Why Congress is examining the partnership
The subcommittee said private-listing systems could divide available inventory, reduce competition, and restrict access to listing information. It also questioned whether the arrangements could encourage private marketing or increase double-ended transactions. MRED said it plans to cooperate with the committee; Compass declined to comment on the letters.
The inquiry follows a July 1 request from the Consumer Federation of America and seven other groups that asked federal regulators to investigate Compass’ MLS agreements over alleged competition, transparency, and fair-housing risks. In a separate federal antitrust case, Zillow alleges Compass and MRED coordinated listing-feed rules to disadvantage the portal. The companies deny unlawful coordination and frame the dispute around seller choice and Zillow’s display standards.
MRED briefly suspended Zillow’s access to its Chicago-area data feeds in May. A federal judge restored the IDX and VOW feeds under a temporary restraining order that also required Zillow to display specified MRED listings. After a July 1–2 hearing and post-hearing briefs, the parties were still awaiting a preliminary-injunction decision in the latest public reporting reviewed.
What agents must verify with sellers and buyers
The inquiry arrives as NAR has issued expanded MLS antitrust guidance for brokers and MLS leaders. NAR’s Clear Cooperation Policy requires covered listings to be submitted to an MLS within one business day of public marketing, including marketing through a multi-brokerage listing-sharing network. A separate policy allows office-exclusive and delayed-marketing exemptions when local rules permit them and the listing broker obtains the required seller certification.
Before recommending private or delayed marketing, agents should explain where the property will appear, who can view it, how long distribution will be limited, and what exposure the seller may lose. Document the seller’s decision and instructions in writing.
Buyer agents should verify which private and delayed-marketing listings they can access and explain known gaps in public portals. Brokerage leaders should review local MLS rules, seller-disclosure forms, and state agency requirements before changing listing workflows.
How the case could reshape listing access
Compass and MRED face an Aug. 5 deadline to arrange the congressional briefings. A ruling in the Zillow case could also determine whether MRED may restrict the portal’s data feeds while the lawsuit proceeds.
The outcome could influence whether other MLSs pursue national private-listing partnerships. Agents should watch for changes to local distribution rules, membership requirements, and seller disclosures — and be prepared to explain why a listing available through professional systems may not appear on public portals.
