In a move reflecting the intensifying battle for dominance in the digital real estate market, CoStar Group has intervened in the ongoing legal dispute between Zillow and Midwest Real Estate Data (MRED). CoStar filed an amicus brief opposing Zillow's motion for a preliminary injunction, alleging that the 'Zillow Preview' initiative is designed to restrict competition and funnel leads exclusively to Zillow-affiliated brokers. According to reports, CoStar seeks to prevent Zillow from maintaining specific data feed advantages that could harm competitors like Homes.com.
This legal escalation comes as real estate tech firms face mounting pressure to restructure their business models amid broader antitrust scrutiny. For context, Zillow reported Q1 2024 revenue of $529 million, a 13% year-over-year increase, according to its latest earnings filing. Meanwhile, CoStar is aggressively positioning its Homes.com platform as a primary challenger, leveraging these legal challenges to question Zillow's market practices and transparency in the industry.
