What CoStar does
CoStar Group, Inc. (NASDAQ: CSGP) is the largest source of verified commercial real estate information and analytics in the United States, founded in 1987 and headquartered in Washington, DC. The company operates a subscription-based platform built around a census-level commercial property database covering 8.5M+ properties, 7M+ lease activities, 5M+ sale comps, and 8.2M+ commercial tenants, assembled over 40+ years by what CoStar describes as the largest dedicated research team in the industry. The product portfolio spans the core CoStar analytics platform, integrated solutions for hotel benchmarking (STR Benchmark, acquired 2019), debt analytics, risk analytics, and lease administration, plus a set of consumer and listing portals — LoopNet, Apartments.com, Homes.com, and Land.com — supported by Matterport 3D digital twin technology.
CoStar serves brokers and agents, owners and investors, corporate occupiers, appraisers, lenders, and hoteliers through vertical segmentation, and has begun extending into residential construction via the pending $800M acquisition of Zonda (announced May 2026, expected close H2 2026). The company employs an enterprise field sales model with regional offices across the US, UK, London, and Singapore, complemented by an online subscription portal with a 'Request Demo' conversion path. Revenue is predominantly recurring subscription income across 300,000+ subscribers, augmented by listing, advertising, and benchmarking services; pricing is quote-based and not publicly disclosed.
The platform is undergoing an AI-enabled refresh through Homes AI (launched February 2026), a Microsoft Azure OpenAI-powered natural-language search assistant that CoStar intends to extend across Apartments.com, LoopNet, Land.com, and CoStar. CoStar also pursues a serial M&A strategy, having added STR (2019), Domain (2022, Australia), Matterport, and the pending Zonda deal; the most recent strategic activity is balanced by concurrent regulatory scrutiny, including a UK CMA investigation into STR-based data sharing among major hotel chains and the revival of CREXi antitrust claims in US courts.
