CoStar Completes $800M Acquisition of Zonda

CoStar Group finalized its acquisition of Zonda for $800 million on October 26, 2026, a move that significantly expands CoStar's footprint in the residential property data and analytics sector. Zonda, previously known as Hanley Wood, is a leading provider of data, analytics, and market intelligence for the U.S. residential construction industry. This acquisition positions CoStar to offer a more comprehensive suite of services to its clients, bridging the gap between new construction and the broader residential market. The integration of Zonda's offerings is expected to enhance CoStar's existing residential segment, which has demonstrated robust growth. In the second quarter of 2026, CoStar's residential segment reported $444 million in revenue, marking a substantial 33% increase year over year. This growth trajectory highlights the increasing demand for detailed property information and analytics in the real estate market. The acquisition of Zonda is strategically aligned with CoStar's long-term vision to become the dominant provider of information and analytics across all major commercial and residential real estate sectors. Zonda's expertise in new home construction data, including builder insights, project pipelines, and market trends, complements CoStar's existing strengths in areas such as multifamily, commercial property, and land data. CoStar Group, headquartered in Washington D.C., is a leading global provider of commercial real estate information, analytics, and online marketplaces. The company operates a portfolio of brands including LoopNet, Apartments.com, and Ten-X, serving a wide range of real estate professionals. Zonda, with its headquarters in Dallas, Texas, has been a key player in providing critical data to home builders, developers, and suppliers, enabling them to make informed decisions about market opportunities and product development. The transaction was structured as an all-cash deal, with CoStar Group funding the acquisition through existing cash reserves and a revolving credit facility. Financial analysts have noted that the acquisition is expected to be accretive to CoStar's earnings per share in the first full year following its completion. The combined entity aims to leverage synergies in data collection, technology platforms, and sales channels to drive further innovation and market penetration. This strategic move by CoStar underscores its commitment to consolidating its position as a comprehensive data powerhouse within the real estate industry, catering to an increasingly data-driven market. The integration process is anticipated to be completed by the end of the first quarter of 2027, with Zonda operating as a distinct brand within CoStar's residential segment.
