Compass Antitrust Suit Adds a New Proposed Lead Plaintiff

What happened

Plaintiffs’ attorneys filed a proposed amended antitrust complaint against Compass International Holdings that names Charles Lieberman as the new proposed lead plaintiff. The prior plaintiffs voluntarily dismissed their claims against Compass, according to the filing described by HousingWire.

The amended complaint retains the central allegation from the original case: that Compass reduced consumer choice and raised rents and brokerage fees by removing rental listings from Zillow-owned StreetEasy. These are allegations in a lawsuit, not findings by a court. Compass declined to comment on the claims in the amended complaint.

The suit again seeks class-action status. Its proposed renter class would cover people who rented residential units in the New York City metropolitan area from Jan. 1, 2026, through the end of the alleged anticompetitive conduct. It also proposes a separate brokers’-fee class for renters who paid a broker fee, directly or indirectly, to Compass or its affiliates.

The key details

According to the amended complaint, Compass encouraged agents ahead of the fall housing market to remove properties from StreetEasy and use the “participant only” setting in the Real Estate Board of New York’s Residential Listing Service, or RLS. The complaint says that setting prevents a listing from being syndicated to, or displayed on, public-facing websites.

The plaintiffs contend that less public exposure to rental inventory reduced available choice for apartment seekers and contributed to higher rents and broker fees. Lieberman’s experience is presented as an example of the claimed harm. The complaint says he found a Manhattan rental on StreetEasy in August 2025 at $4,000 per month, with a broker fee bringing the price to $4,620 per month. When he searched again in August 2026, the filing alleges that reduced publicly available listings left him renewing his current lease at $4,850.

The complaint characterizes the $4,850 rent as above a competitive level and argues that some or all of the difference, as well as the broker-fee cost alleged by Lieberman, would not have existed without a severe reduction in public StreetEasy rental listings. Lieberman requests a jury trial, damages, and injunctive relief that would require Compass to stop the conduct alleged to be unlawful.

Compass previously told HousingWire that temporarily taking listings off the web in August was a common strategy among top agents. The company said the approach was not aimed at any particular portal, and that the listings remained visible to agents at all REBNY brokerages and to their clients through the RLS. Compass also said the strategy gives sellers broad exposure while listings are temporarily off the web during what it described as New York City’s slowest month.

Why it matters

The amended filing places the dispute squarely around the difference between access within the broker-facing RLS and visibility on public listing websites. For the proposed renter class, the plaintiffs are asking a court to assess whether the alleged shift in how rentals were displayed restricted competition and caused financial harm.

The case arrives while Compass is also facing antitrust claims in a lawsuit brought by Zillow against Compass and Midwest Real Estate Data. HousingWire also reported that a House Judiciary Committee has raised questions about the Compass-MRED partnership over potential effects on transparency and competition, and that the New York attorney general’s office is allegedly examining Compass’s acquisition of Anywhere over antitrust concerns.

What to watch

The immediate procedural question is whether the amended complaint will proceed with Lieberman as lead plaintiff after the earlier plaintiffs’ voluntary dismissal. Subsequent court decisions could address the proposed classes, the allegations of harm, and the requested damages and injunctive relief.

It will also be important to watch for any formal response from Compass and for further detail on the alleged use of the RLS “participant only” designation. The case has not established that Compass engaged in unlawful conduct.
