Hidden Zillow Listings Suit Turns Broker Inventory Fight Into Antitrust Case
Ars Technica reported that New York renters accuse Compass of hiding enough rental listings from StreetEasy to create an artificial supply shock and raise Manhattan rents.
A proposed New York class action turns a fight over hidden rental listings into a platform-market antitrust case, Ars Technica reported.
The complaint accuses brokerage firm Compass of pulling enough Manhattan rental inventory away from free listing platforms such as Zillow-owned StreetEasy to create an artificial supply shock for renters.
Plaintiffs Peter Castaneda and Haley Gelfand allege that Compass controls more than 80 percent of Manhattan rental-unit listings based on 2025 data.
Their complaint says that position lets the company influence pricing across a large share of the borough's rental market, while higher rents can also lift broker fees that are often tied to rent prices.
The Zillow dispute sits at the center of the case.
StreetEasy gives New York renters a way to search for apartments without paying a broker fee, while the complaint describes Compass as delisting thousands of homes from Zillow earlier this year.
Zillow responded with listing standards that exclude privately marketed homes from later appearing on its sites, and Compass then filed an antitrust suit against Zillow before voluntarily dismissing it in March after an early court setback.
Regulators and lawmakers have already begun looking at the same market structure.
U.S. Senator Elizabeth Warren has warned that exclusive listing practices could create a two-tier housing market in which insiders pay for access to inventory and market data while other renters are left outside.
Local and federal authorities have also opened antitrust probes into Compass' effect on real estate markets.
The renters tie the platform dispute to lease prices.
Castaneda's lease and Gelfand's filing account both place their apartment searches inside a period when the complaint says StreetEasy prices were rising and comparable local asking rents were lower.
That evidence is presented as part of the damages theory, not as a final finding by the court.
The complaint points to market data showing available New York rental units down 40 percent over the past year, with rental-price increases moving from 3 percent in June to 6 percent in July as inventory kept falling.
Compass declined Ars Technica's request for comment, while Zillow said deliberately hidden listings make real consumers pay the price.
The proposed class would cover New York City renters who leased non-rent-stabilized multifamily residential units from August 1, 2026, onward.
The plaintiffs seek damages, disgorgement of alleged unjust enrichment and an injunction blocking Compass from hiding listings from platforms such as Zillow.
