Baird & Warner and Real Estate One have agreed to contribute an additional $3.7 million to a fund related to the ongoing MLS PIN antitrust case, which has resumed after a pause. The court is set to consider the approval of a deal that facilitates commission sharing within the multiple listing system. The companies were among the last entities not included in the National Association of Realtors (NAR) settlement and will collectively pay over $10.5 million in damages. In a related antitrust complaint, a broker is challenging NAR's three-way agreement and other membership rules. Additionally, Side and other brokerages, along with two MLSs, will pay $10,570,000 to settle a new antitrust case if the proposed terms are approved.
