The deal brings Zonda’s construction data, 3,000-plus B2B customers and consumer marketplaces into CoStar’s portfolio, creating new opportunities to combine analytics, listings and 3D property technology for builders, lenders and buyers.
CoStar closed its $800 million purchase of Zonda, adding construction-focused data and marketplaces to its products.
Zonda supplies data tools to more than 3,000 customers and operates consumer marketplaces NewHomeSource and Livabl.
CoStar plans to integrate Zonda’s assets with its existing platforms and Matterport 3D tech to expand services for builders, lenders and buyers.
# What happened CoStar Group has completed its $800 million acquisition of Zonda, a company that provides housing construction data, analytics and marketplaces for the new-home sector. The closing was announced Aug. 21, 2026.
# Why this matters The purchase gives CoStar a direct foothold in the new-home construction market, an area the company described as "massive." Zonda supplies construction data and software to builders, developers, lenders and suppliers, and operates consumer-facing marketplaces where builders list inventory for prospective buyers. Bringing those capabilities into CoStar's technology stack expands the company beyond its commercial and existing residential products.
# What Zonda brings
These assets are purpose-built for the homebuilding ecosystem and are complementary to CoStar's existing property information, analytics and marketplace businesses.
# Zonda CoStar's CEO said the company will integrate Zonda's data and relationships with CoStar's technology to deliver analytics and marketing solutions for builders, lenders and other participants. Specific intentions mentioned include:
# Practical implications for industry players Builders and developers: Access to combined data and marketplace tools could streamline how they list inventory, market homes and reach buyers.
Lenders and investors: Integrated analytics tailored to new construction could improve underwriting, risk assessment and market intelligence.
Suppliers and service providers: A centralized marketplace and richer data may make it easier to identify demand trends and buyer preferences.
Buyers: Consumer marketplaces could gain richer listings and immersive 3D visuals if CoStar implements Matterport enhancements on NewHomeSource and Livabl.
# What CoStar gains strategically CoStar has spent decades building property information, analytics and online marketplaces across commercial and residential segments. Zonda extends that model into new residential construction, giving CoStar an established customer base and a pathway to develop new products and marketplaces specifically for the homebuilding ecosystem.
# Immediate next steps indicated The announcement frames the transaction as closed and signals integration work: combining Zonda's data and client relationships with CoStar's platforms and Matterport capabilities. No financial specifics beyond the purchase price were provided about integration costs or timelines.
# Bottom line CoStar's acquisition of Zonda brings construction-focused data, a large B2B customer base and consumer marketplaces into its portfolio. The company intends to merge those assets with its analytics and 3D listing technology to offer new tools for builders, lenders and buyers in the new-home market.
