CoStar Group to Acquire Data Provider Zonda for $800M

Commercial real estate data firm CoStar Group is in the closing stages of buying the housing market data specialist Zonda for $800 million in an all-cash deal that will close in the second half of 2026.

Zonda is a leading provider of new home construction data, homebuilder software, and residential real estate marketplaces, tracking housing starts and builder activity that help builders, developers, and housing professionals make smarter decisions throughout the homebuilding lifecycle.

The acquisition will boost CoStar's industry-leading residential data offering with a special focus on new homes, for which Zonda operates leading new-home marketplaces in the United States and Canada, NewHomeSource and Livabl.

According to a press release, Zonda's platform delivers end-to-end solutions spanning land acquisition, development planning, homebuilding analytics, construction forecasting, community marketing, operational workflow management, and online new home marketplaces. Zonda is an attractive B2B business with strong profit margins.

CoStar added that Zonda's 'Envision' visualisation and digital merchandising capabilities will be paired with Matterport's spatial technology to create "richer digital experiences for builders and consumers", improving how new construction homes are marketed, visualised, and discovered online.

Andy Florance, CEO and founder at CoStar Group, said:

"Zonda has built an extraordinary business with deep relationships across the homebuilding industry and one of the most valuable proprietary datasets in new home real estate.

"This acquisition extends CoStar Group's leadership into a major new segment of the real estate industry and strengthens our ability to provide clients with comprehensive information solutions across every major real estate segment. We believe the combination will deliver deeper insights, workflow efficiencies, and analytics to the homebuilding industry, while strengthening our core information offerings and significantly expanding our new home marketplace capabilities."

CoStar Group's latest financial results saw revenues of $897M in the first three months of the year.
