Edelson PC's Natasha Fernández-Silber has been appointed Interim Co-Lead Class Counsel in In re: CoStar Group Antitrust Litigation, No. 3:26-md-03192-DJN (E.D. Va.).
She and the firm represent a proposed class of commercial real estate brokers who allege CoStar engaged in an exclusive-dealing scheme to lock up listing data in the commercial real estate information services market, in violation of Sections 1 and 2 of the Sherman Act.
This alleged scheme allows CoStar to operate the dominant platform brokers rely on for property listings, comparables, and market data — and to charge brokers inflated subscription prices as a result.
