CoStar Closes $800M Zonda Acquisition, Expanding Its New-Home Data Business
CoStar Group says it completed its $800 million cash acquisition of Zonda, adding new-home construction data, software and marketplaces to its residential business.
CoStar Group has completed its $800 million cash acquisition of Zonda, adding a new-home construction data, software and marketplace business to its growing residential real-estate portfolio. The company announced the closing Friday, saying required regulatory approvals and customary closing conditions had been satisfied.
The deal brings Zonda’s business-to-business homebuilding information platform, along with the consumer-facing NewHomeSource.com and Livabl marketplaces, under CoStar’s umbrella. CoStar said the transaction expands its property-data, analytics and marketplace capabilities into the U.S. new-construction sector.
What CoStar says it acquired
Zonda supplies data, software and research used across the new-home development cycle, from land acquisition and development planning through construction forecasting, community marketing and home sales. CoStar said Zonda serves more than 3,000 customers, including homebuilders, developers, suppliers and lenders.
According to CoStar’s announcement, Zonda generated approximately $170 million in 2025 revenue and had an Adjusted EBITDA margin of 23%. Those figures are company-reported, and the adjusted margin is a non-GAAP measure. CoStar also described the acquired business as a subscription-led platform with a proprietary lot-level database covering new-home communities, land development, construction status, sales activity and builder operations.
A larger push into new construction
CoStar already operates property-information and marketplace brands including CoStar, LoopNet, Apartments.com, Homes.com and Matterport. The Zonda purchase gives it a dedicated foothold in the new-home segment, where builders and lenders use specialized information to make decisions about land, financing, development timing and marketing.
The company said the U.S. new-home market represents roughly $400 billion in annual home sales. It also said Zonda’s Envision visualization and digital-merchandising capabilities could be combined with Matterport’s spatial technology. These are management’s stated strategic expectations, not completed operating results.
What happens next
With the transaction closed, the focus shifts to integration. CoStar says it sees opportunities to introduce Zonda’s information and marketplace offerings to more of its customers and to bring CoStar’s analytics products to Zonda’s customer base. Whether those plans produce the anticipated growth or profitability benefits remains subject to the usual execution, market-cycle and customer-retention risks identified in CoStar’s release.
CoStar reported second-quarter 2026 revenue of $925 million, up 18% from a year earlier, in the same announcement. It said residential revenue increased 33% year over year to $444 million. The company previously announced its agreement to acquire Zonda on May 29.
